TECHNICAL INFORMATION
Process plant in borosilicate glass 3.3 QVF process plant and pipeline components manufactured from borosilicate glass 3.3are widely used as the basis for the construction of complete process systemsthroughout the chemical and pharmaceutical industries, as well as many related areas such as food and drink production, dye works and the electroplating industry.One reason for this widespread use is the special properties of borosilicate glass 3.3(see below), complemented by the use of other highly corrosion resistant materialssuch as PTFE and ceramics. Secondly, borosilicate glass is an approved and provenmaterial in the construction of pressure equipment.
Another point which should be mentioned in this context is the great reliability of thepositive and high performance connection of all components. This is achieved by theuse of flat buttress ends, properly designed and optimised throughout the range ofnominal sizes to comply with the special requirements of the material, and a reliableflange system.
The full range of standard components and associated equipment available is described in the following sections of this catalogue.
Chemical composition of borosilicate glass 3.3The special properties – especially its high chemical resistance, its resistance to temperature and its low coefficient of linear expansion – of the borosilicate glass 3.3exclusively used by QVF for the construction of glass plant and pipeline are achievedby strict adherence to its chemical composition, which is as follows:
Properties of borosilicate glass 3.3The very wide use of this material throughout the world in the chemical and pharmaceutical industries as well as many other allied areas, is mainly due to its chemical and thermal properties (see also ISO 3585) together with a great number of other benefits that distinguish borosilicate glass 3.3 from other materials ofconstruction. These include special properties such as
• smooth, non-porous surface
• no catalytic effect
• no adverse physiological properties
• neutral smell and taste
• non-flammability
• transparency

TECHNICAL INFORMATION
Chemical resistanceBorosilicate glass 3.3 is resistant to chemical attack by almost all products, whichmakes its resistance much more comprehensive than that of other well-knownmaterials. It is highly resistant to water, saline solutions, organic substances, halogenssuch as chlorine and bromine and also many acids. There are only a few chemicalswhich can cause noticeable corrosion of the glass surface namely hydrofluoric acid,concentrated phosphoric acid and strong caustic solutions at elevated temperatures.However, at ambient temperatures caustic solutions up to 30% concentration can behandled by borosilicate glass without difficulty.
Borosilicate glass 3.3 can be classified in accordance with the relevant test methods asfollows (see also ISO 3585 and EN 1595):
Further information about acid and alkali attack can be obtained from the followingfigures.
The corrosion curves in fig.1 show a maximum for different acids in the concentrationrange between 4 and 7 N (HCl for example at the azeotrope with 20.2 wt %). Abovethat the reaction speed decreases markedly so that the eroded layer amounts to onlya few thousandths of millimetre after some years. There is, therefore, justification forreferring to borosilicate glass 3.3 as an acid-resistant material.

TECHNICAL INFORMATION
It can be seen from the corrosion curves in fig. 2 that the attack on the glass surfaceinitially increases as the concentration of the caustic solution increases but afterexceeding a maximum it assumes a virtually constant value. Rising temperaturesincrease the corrosion, while at low temperatures the reaction speed is so low thatreduction of the wall thickness is hardly detectable over a number of years.
Physical propertiesBorosilicate glass 3.3 differs from other materials of construction used for processplant not only because of its virtually universal resistance to corrosion (see above) butalso because of its very low thermal expansion coefficient. There is, therefore, no needfor expensive measures to compensate for thermal expansion resulting from changesin temperature. This becomes of particular significance in the layout of long runs ofglass pipeline.
The most important physical properties for the construction of plant are listed below(see also ISO 3585 and EN 1595).

Optical propertiesBorosilicate glass 3.3 shows no appreciable light absorption in the visible area of thespectrum, and consequently it is clear and colourless.
With borosilicate glass 3.3, the transmission of UV light, which is of great importancefor photo-chemical reactions, is somewhat greater in the middle spectrum than withnormal window glass. The chlorine molecule absorbs in the 280 to 400 nm range, andthus from the levels of transmission shown in fig. 3, it can be seen that plant madefrom this material is, therefore, ideal for chlorination and sulphochlorination processes.
If photosensitive substances are being processed, it is recommended that browncoated borosilicate glass 3.3 be used. This special coating reduces the UV lighttransmission to a minimum, since the absorption limit, as can also be seen from thefigure below, is changed to approximately 500 nm.
Sectrans coated glass components, which have an absorption limit of approximately380 nm, are also ideal for these applications.

Mechanical propertiesThe permissible tensile strength of borosilicate glass 3.3 (see table 4) includes a safety factor which takes into account practical experience on the behaviour of glassand, in particular, the fact that it is a non-ductile material. Unlike other materials ofconstruction used for similar purposes, it is not able to equalise stresses occurring atlocal irregularities or flaws, as happens in the case of ductile materials such as metals.The safety factor also takes into account additional processing which componentsmay have undergone (ground sealing surfaces), handling of the glass (minute surfacedamage) and permissible pressures and temperatures to which it may be subjected inuse.
The design figures indicated in the table below and specified in EN 1595 thereforeapply to the permissible tensile, bending and compressive stress to which glasscomponents may be subjected taking into account the likely surface condition of theglass in service.
1.6
TECHNICAL INFORMATION
Permissible operating conditionsThe permissible values for operating temperature and pressure must always be seen incombination. The reason for this is the thermal stresses that result from temperaturedifferences between the inner and outer surfaces of the glass component. Thesestresses are superimposed on the stresses resulting from the working pressure. Higherthermal stresses therefore result in a reduction of the permissible working pressure.Thermal insulation reduces the thermal stresses and can, therefore, become arequirement of an installation.
Permissible operating temperatureBorosilicate glass only deforms at temperatures which approach its transformationtemperature (approximately 525 ºC) and up to this point it retains its mechanicalstrength. The permissible operating temperature is, however, considerably lower –normally around 200 °C – for glass components, provided that there is no suddentemperature shock and that the components are not specially marked (see page 1.8).In exceptional cases, which call for special precautions, temperatures up to 300°C arealso possible.
At sub-zero temperatures tensile strength tends to increase. Borosilicate glass 3.3 can,therefore, be used safely at temperatures as low as -80 ºC.
These temperature limits should be regarded only as a guideline and must always bemodified in accordance with the actual operating conditions of a given application. Theindividual operating conditions of some components in this catalogue must also beconsidered. Where such operating limits apply, they are detailed in the individualcatalogue sections and component descriptions
Thermal shockRapid changes in temperature across the walls of glass components should be avoidedduring operation both indoors and outside. They result in increased thermal stress inthe glass which, as described above, has an adverse effect on the permissibleoperating pressure of the plant components. Although it is not possible to give a definitefigure applicable to all the operating conditions likely to be encountered in practice, amaximum permissible thermal shock of 120 K can be taken as a general guide.
Permissible operating pressureGlass components in all nominal sizes that are basically cylindrical, domed andspherical can be used with full vacuum (-1 bar g), provided they are not speciallymarked otherwise.
Likewise the maximum permissible operating pressures (ps) shown in tables 5 to 8apply to these glass components as a function of their principal nominal size DN ordiameter D (in the case of spherical vessels) and the internal (product side) and external(ambient) temperature difference (DQ). Further details with regard to the sizing ofborosilicate glass 3.3 components can be found in the next section.
Jacketed glass components are dealt with on page 1.10.
The internal areas of heat exchangers are dealt with separately in Section 5 underthe particular product description. In cases where glass equipment is operatedwith a gas pressure, appropriate safety precautions are required and oursales engineers will be happy to discuss these with you.
Depending on the shape and the particular working conditions, glass components canbe used under certain circumstances at higher internal pressures. In these cases, theglass component is specially marked on in accordance with EN 1595.

The permissible pressure.
This ranges from -1 bar g (vacuum) up to a pressure of 4 bar g (DN 15 to DN 50) and 0.6bar g (DN 1000) or 1 bar g (10l and 20l flasks) and 0.3 bar g (500l flasks).
The permissible temperature difference (∆Θ) between the outside area (ambient) andinterior (product area).
For standard glass components this has been fixed at 180 K which corresponds to thedifference between the permissible operating temperature of 200 ºC and the ambienttemperature of 20 ºC. At higher temperature differences the permissible pressure range willbe reduced.
The heat transfer coefficient (αa) at the surface of the glass.
This depends on the location of the installation and has a significant influence on thetemperature difference ∆T = u·∆Θ·s/λ between inner and outer surfaces of the glasswall of the component. Increasing values of the wall temperature difference resultsin a decrease in the permissible operating pressure or vacuum because of increasedthermal stresses. The heat transfer values indicated in the table below have beenselected on the basis of calculations and practical experience.

TECHNICAL INFORMATION
Grooves in the fire-polished sealing surface in the DN 15 to DN 300 nominal sizerange securely locate the O-ring gasket in place and prevent it being pushed out bythe internal pressure.
Flexible gaskets (see Section 9 "Couplings”) facilitate deflections of up to 3° so thateven complicated systems can be laid out simply and securely.

Glass components with safety flat buttress end can be connected direct tospherical ended components by means of the glass or PTFE adaptors descri-bed in Section 2 "Pipeline Components”.
Safety flat buttress endsIn practice the buttress end areas of borosilicate glass components have to withstandnot only the tensile and compressive stresses resulting from being operated underpressure or vacuum, and the thermal stresses caused by the operating temperature,but also the stresses set up by the bolting forces in the coupling. Engineering a safebuttress end therefore involves ensuring that the sum of these stresses is minimised.The design of the flange coupling and the fire polished sealing surface both makesignificant contributions to this end.
The major dimensions of the safety flat buttress ends can be found in the table below,in conjunction with the illustrations alongside.

All components with safety flat buttress ends produce positive and high performanceconnections ensuring safety in operation when used in conjunction with the couplingsdescribed in Section 9 "Couplings”. The following significant details are especiallynoteworthy in this context:
KF Pipe EndsIn addition to the safety flat buttress ends, QVF also supplies other pipe systems, suchas the ball/socket (KF) system from Schott. This pipe end enables deflection of theconnection without an additional joint element, and the systems is described fully inthe special supplement "KF Pipe Line Systems" including the accompanyingconnections and fittings. It offers full compatibility to the former Schott systemdescribed in catalogue 6076.
The dimensions are laid down in the special supplement.

TECHNICAL INFORMATION
Jacketed glass componentsThese borosilicate glass 3.3 components provide a solution that meets requirementsencountered in practice. They have proved their worth to excellent effect throughoutthe chemical and pharmaceutical industries as well as many related areas such asfood and drink production, dye works and the electroplating industry. They are usednot only to avoid heat loss for the purpose of saving energy but also where the producttemperature has to be maintained to prevent crystallising or undesirable reactions.This is achieved without losing the benefit of being able to monitor the process visually.
Jacketed versions of all the major glass components of our modular system areavailable. The range therefore includes not only pipeline components but also valvesand vessels as well as a wide variety of column components.
In the case of shorter pipe sections, fittings and spherical vessels up to 50 l nominalcapacity, the jacket is one-piece and welded at both ends. In all other cases, thedifferent linear expansion of the basic component and the jacket has to becompensated for by other means. On longer pipe sections the jacket is welded at bothends but it has a flexibly sealed expansion joint in the middle. On vessels it is weldedonly at the upper end and at the bottom it has a flexible seal.
The connections on the jacket are standard safety flat buttress ends. Further details onconnection options can be found in the respective product description.
Permissible operating conditionsThe permissible operating pressures for the inner part of jacketed components areidentical to those for their non-jacketed counterparts (see page 1.7). However,deviations will arise in the permissible operating temperatures for the inner part andthe permissible operating conditions in the jacket itself. These are caused by thepermanently flexible seal, which absorbs the different expansion levels of the innercomponent and the jacket, but does not have the high temperature resistance andstrength of borosilicate glass.
Permissible operating temperature: Taking into account a sufficiently high safety factor, the permissible operatingtemperature for the inner component is -80 ºC to +200 ºC and for the jacket it is -50ºC to +180 ºC. The maximum permissible temperature difference (∆Θ) between theinner and outer areas is 180 K.
Permissible operating pressure: The maximum permissible operating pressure in the jacket is +0.5 bar g up to anoverall heat transfer coefficient of u = 70Wm-2K-1. This average value can be expectedduring a heating process with thermal oil in the jacket and stirred liquid inside thevessel.
GMP-compliant installationsSpecial care is required in the selection of components and equipment for theconstruction of installations complying with GMP guidelines as regards their designand the materials of construction used. Because of its special properties, which arehighly valued in the pharmaceutical industry, and when used in conjunction withmaterials on the FDA-approved list such as glass lined steel (vessels, valves) and PTFE(bellows, linings, cladding) borosilicate glass 3.3 guarantees that the build-up ofdeposits is avoided in areas in contact with the product. Minimum dead space toensure complete draining and a capability for simple and effective cleaning areachieved by the design of the components, their layout and the selection of suitablevalves. Stainless steel coupling and support material is available (see Section 9"Couplings” and Section 10 "Structures & Supports”) for the design of complete unitscomplying with clean room conditions from the external aspect.
Jacketed components can be found in the appropriate section of this catalogue.
1.11
TECHNICAL INFORMATION
Protection against mechanical damageBorosilicate glass 3.3 components can be CORWRAP or Sectrans coated to protectthe glass surface against external damage such as scratching or impact. Both versionscan be applied to almost all glass components irrespective of their shape. Both haveexcellent resistance to chemicals and weathering. They present no health risk andheating them does not give rise to any unpleasant odours or gases.
External protection of borosilicate glass 3.3 pressure vessels against mechanicaldamage in working areas and areas subject to traffic can be provided by safetyscreens. The use of these is to be recommended and in some areas it is a legalrequirement (e.g. to comply with Point 9 of the TRB 801 Technical Regulations forPressure Vessels in Germany).
Coated and wrapped glass componentsSectrans is a highly transparent polyurethane-based coating that is applied to theglass component by spraying to a defined thickness. The permissible long-termoperating temperature for this material is 140 ºC, but it can also go up to 180 ºC forshort periods. Above 140 ºC the coating can turn yellow, but this has no adverse effecton its protection function and transparency.
All Sectrans coating is dissipative and may be used within Ex-areas.
In the event of the glass being broken, the Sectrans coating provides protectionagainst splintering. If no pressure is involved, limited protection against the productescaping is provided. However if the glass component is being used at the permissibleoperating pressure the contents can escape.
The coating incorporates UV protection so that it can be used for handlingphotosensitive substances.
The CORWRAP coating comprises of an impregnated glass fiber mat, which is cut tothe outer form of the glass and is wrapped in an overlapped fashion. This glass fiberreinforced polyester jacket is also almost transparent, yet it does not achieve thedegree of transparency of a Sectrans coating. The maximum permissible operatingtemperature for CORWRAP coated glass parts is about 150°C.
In case of glass fracture, the CORWAP coating also offers protection against splitters,and prevents the outflow of fluid at pressure-free operation.
In the event of the glass being broken, the GRP wrapping also provides protection againstsplintering and if no pressure is involved it prevents liquid escaping. Where low pressure isinvolved, there is limited protection against the product escaping which provides anemergency evacuation capability in the event of breakdown.
Coating or wrapping glass components does not increase their permissibleoperating pressure in any way.
When ordering Sectrans coated components the suffix "L” should be addedto the catalogue reference given in this catalogue, e.g. "PS100/500L”. ForGRP wrapped components the suffix "C” should be added, e.g. "PS100/500C”.
If CORWRAP coated glass parts are to be used in explosion rated areas of thecategory 1 or 2 (formerly zone 0 or 1), these shall be provided with a conduc-tive coating.
We would be happy to advise you on the basis of the regulatory requirementsapplicable in each particular case and the guidelines drawn up by ourselves for thedesign of GMP-compliant plant.

TECHNICAL INFORMATION
Safety screensSimple versions, such as wire mesh or expanded metal in box-section frames are ofcourse a low cost solution, but not user-friendly. This applies especially when the plantneeds protection on all sides. There is no doubt that it is better to use transparentplastic safety screens with frames that are self-supporting or fixed to the supportstructure and which can be equipped with covered service openings.
The best solution is to use safety screens consisting of medium flexibility transparentPVC which has a high resistance to abrasion. To ensure good lateral stability, thesehave galvanised metal strips bolted on at the top and bottom. Hooks are also fitted tothe top edge to enable the safety screen to be suspended from the structure.Swivelling versions and covered service openings guarantee optimum ease of use.The screens can be individually adapted to local conditions as they are subdivided intooverlapping sections.
For installations where electrostatic charges can be expected the screens can besupplied with an antistatic coating. This reduces the conductor resistance to less than10 8ž. The temperature of use of this material is between -40 and +40 ºC. It has limitedresistance to organic substances and adequate resistance to inorganic substances.
Glass Facilities Within Ex AreasIf ignition risks occur due to electrostatic charging during the operation of glassfacilities within explosion-endangered areas, relevant protective measures arenecessary, whose scope is aligned to the probability of occurrence for an explosion-capable environment. Details regarding the creation, assessment and prevention ofspark dangers due to electrostatic charging may be viewed in the regulation BGR 132edited by the German BG Chemistry.
The requirements of BGR 132 and the EU directive 94/9/EG have been implementedby QVF within a step-type safety concept so that the correct parts and safetymeasures may be chosen contingent to the zone type, explosion group, and theprocedure deployed. Thus, conductive PTFE and metal parts with earthing clips areavailable that are marked by a suffix "D" meaning "dissipative".
As the accumulation of charges in metal flanges must especially be avoided, thestandard usage of plastic flanges up to nominal diameters of DN 300 are of specialadvantage as these cannot accumulate explosive charge levels.
The Sectrans coating of glass is a standard product manufactured to be conductive,and may be deployed in ex areas. If one may expect dangerous charge accumulationon the glass surface in the course of a risk assessment, QVF offers a patented solutionfor the conductivity of the coated glass surfaces.
If it is necessary to earth metal parts this should be done by connecting them to anelectric protective conductor (drives etc) or by fitting conductive earthed points to thecomponents to be earthed. In the glass plant it is advisable not to earth all parts of theplant individually but to interconnect them in a continuous circuit. This can done bymeans of a main conductor located parallel to the column, pipeline etc to which thecomponents requiring earthing can be connected. By "earthing” it is to be understoodin this context that the conductor resistance,(i.e. the electrical resistance of theearthing between an electrode set up on one side and earth) is not greater than 106Ω.
Consideration of mechanical sources for sparks as required by the EU directive94/9/EG has been performed for QVF products. Drives with dual-action and single-action mechanical seals with ATEX conforming certificates are included.
1.13
TECHNICAL INFORMATION
Marking of electrical equipmentWith the introduction of EC directive 94/9/EC (ATEX 100a) additional marking ofequipment for use in explosive atmospheres is required. This indicates the area inwhich the equipment can be used, i.e. new EC test certificates (replacing theconformity certificates to directive 76/117/EEC) do not now contain any specialindication with regard to permissible use in a specific flameproof zone.
In process engineering installations, the relevant markings are "II 1G” and "II 2G” formeasurement and control instruments and "II 2G” for motors, where "II” means theappliance group (allowing the appliance to be used in any area except mining), "1” or"2” the category (formerly zone) and "G” (standing for gases and vapours) the type ofexplosive atmosphere.
As the marking prescribed by CENELEC, e.g. "EEx e II T4” or "EEx ia IIC T6” has beenretained and the information called for in ATEX 100a must be added, the full newmarking for this equipment is "II 2G EEx e II T4” or "II 2G EEx ia IIC T6”.
Risk analysis / residual risks All the components and apparatus in the 2002 edition of the QVF catalogue have beensubjected to a risk analysis in accordance with Directive 97/23/EC and thecorresponding countermeasures are documented by QVF. To exclude risks above andbeyond these resulting from improper use (Directive 97/23/EC, Appendix I, Section 1-3) the following points should be observed:
• Although borosilicate glass 3.3 is a material resistant to virtually all chemicalattack, alkaline solutions, hydrofluoric acid and concentrated phosphoric acid can cause some erosion. If there is any concern that there may be a reduction in wall thickness, the required minimum wall thickness should be checked at regular intervals.
• Unstable fluids, substances that can decompose, call for special safety precautions in the use of glass plant.
• The permissible operating conditions in accordance with section 1 the catalogue,page 1.6, should be observed and compliance ensured if necessary by means of additional measures such as pressure relief valves, bursting disks, over-fill preventi on or temperature limiters.
- Permissible operating pressures:The permissible operating pressure should be observed in every case, including when commissioning, checking for leaks and filling the plant.
- Permissible operating temperature:The maximum operating temperature for glass components is 200°C and this should be observed and where necessary, e.g. with electrical heating or exothermic reaction, ensured by the use of suitable measuring quipment.
- Permissible thermal shock:Borosilicate glass can withstand thermal shocks up to 120 K. For plants operating at temperatures in excess of 120 °C, and which are not protected by insulation, the thermal shock limit could be exceeded by cold water sprayed onto the equipment by a sprinkler system. To avoid this, sprinkler heads should not be mounted in the vicinity of unprotected glass process plant. In the event of a fire high temperatures may arise which could also result in breakage of the glass.
• Extra loads, such as reaction forces on side branches, are not permissible. Bellows should be included in interconnecting pipework to ensure a stress-free connection to the glass plant.
• Mechanical damage / protective measures:The tubular structure supporting the equipment or plant also provides protection against damage from external sources and prevents other items coming into contact with it.
Parts of the plant which are located outside the structure must be protected against mechanical damage.
1.14
TECHNICAL INFORMATION
Parts of the plant, which can reach a surface temperature higher than 60° C inoperation and which are located outside the support structure, must be provided with protection against contact.
Additional safety devices are available in the form of safety screens, spray guards, coated and wrapped glass components (see section 1 of the catalogue,pages 1.11 and 1.12).
• Damage to heat exchangers:Should damage occur to the coil batteries in coil type heat exchangers or the heat exchange tubes in shell and tube heat exchangers, the service fluid and product can become mixed.
Media, wich could react resulting in the generation of pressure and temperature (exothermic processes), should therefore be kept separate.

PIPELINE COMPONENTS
IntroductionQVF borosilicate glass 3.3 pipeline is widely used in the chemical, pharmaceutical andallied industries together with other applications such as food and drink production, dyeworks and electroplating. This is because of the special properties of borosilicate glass3.3 and PTFE (gaskets) plus the fact that borosilicate glass 3.3 is an approved andproven material of construction for pressure vessels.
Reference should also be made in this context to the extreme reliability of the improved,strong and high-duty coupling system used for all components. This is achievedthroughout the whole range of nominal sizes by the use of the safety buttress end whichhas been designed specifically by taking into account the properties of the materialcombined with a reliable flange system.
The complete range of standard pipeline components is described on the followingpages. Non-standard components can also be supplied to special order.
A detailed listing of all catalogue components by »Description« and »Reference« can befound in the »Index«.
Many of the components listed in this section are not only used in pipelines but also usedin the design of process plant. For example pipe sections are used in columns, feedpipes are fitted in reducing tee pieces and reducers are also used as the top or bottomcomponent in columns.
Detailed information on a number of the topics referred to in the followingpages can be found in Section 1 »Technical Information«.
A deviation of up to 3º can be achieved by using the flexible gaskets describedin Section 9 »Couplings« which considerably simplifies the design andinstallation of complicated pipeline systems.
Details of the design of the different types of optimised buttress ends areillustrated alongside.
Metric grid modular systemThe pipeline components in the DN 15 to DN 150 nominal size range (pipe sections alsoup to DN 1000) described in this section comply with EN 12585 "Pipeline and Fittings,Compatibility and Interchangeability” and are conceived as a modular system. The onlyexception to this is the side branch on some reducing tee pieces. The basic unit ofmeasurement is 25 mm and all component dimensions are a multiple of this basic length.The resultant metric grid system facilitates trouble-free design and installation of systemswith these components.
In addition, all fittings and valves (please see Section 3 »Valves & Filters«) in the samenominal size always have the same limb length, so that bends can be interchanged withtee pieces or tee pieces with valves etc. This means that any modifications which maybe required to existing pipelines can be carried out quickly and easily.
GMP compliant installationsThe layout of pipelines when designing plant and equipment complying with GMPregulations calls for special care in both the planning and selection of the components,together with the materials of construction used for them. Borosilicate glass 3.3 has anumber of special properties that are highly valued in the pharmaceutical industry andthese, in conjunction with PTFE materials (gaskets) approved in accordance with theFDA catalogue, ensure that any build-up of unwanted deposits is avoided in areas whichcome in contact with the product. A design without any dead space, which ensures thatcomponents drain fully and can be cleaned easily and effectively, is achieved by theshape of the components and the way they are installed. Where the external surfacesof the pipeline have to comply with clean room requirements,appropriate stainless steelcoupling and support material can be supplied (please see Section 9 "Couplings” andSection 10 »Structures and Supports«).

PIPELINE COMPONENTS
Components suitable for higher permissible operating conditions can be supplied on request.
We would be happy to advise you on the basis of the regulatory requirements applicableto a particular case and the guidelines drawn up by ourselves for the design of GMPcompliant plant.
Horizontally installed pipelineWhereas vertical pipelines only have to support their own weight, bow can also occurin horizontal lines as a result of the additional weight of the liquids they contain. To reducethe resultant stress to a permissible level, supports should be provided at adequateintervals. The maximum spacing of these is indicated in Section 10 »Structures andSupports« as a function of the density ρ of the product being conveyed.
Coated pipeline componentsDamage to borosilicate glass 3.3 components resulting from accidental external causescannot be entirely excluded, especially in the smaller nominal sizes. This is primarily dueto the relatively rigorous conditions prevalent in production plants and applies especiallywhere no additional protection is provided in the form of insulation.
Our answer to this problem is to provide borosilicate glass 3.3 pipeline components witha Sectrans transparent coating. This can be applied irrespective of the shape of thecomponent and it provides additional protection without having any adverse effect onvisual monitoring of the process.
A glass fibre reinforced polyester coating providing a higher level of protection can alsobe supplied on request. This does have a slightly adverse effect on the transparency ofthe glass, making it translucent and not transparent.
Permissible operating conditionsWhile the maximum permissible operating temperature for all borosilicate glass 3.3pipeline components is generally 200 ºC (³Q • 180 K), the maximum permissible operatingpressure is governed by the main nominal size of the component but not by its shape.Detailed information on this and the operation of jacketed components can be found inSection 1 »Technical Information«.
The permissible operating conditions for components in other materials can be foundin the respective product description.
The drainline piping systemFor drainage, venting and dye lines, we recommend our beaded end borosilicate glass3.3 drainline piping as an especially economical solution. All components can be used up to a maximum permissible operating pressure of 0.5 bar g.

PIPELINE COMPONENTS
Pipe sections are used not only in pipeline systems but also in the design of columns.
For example, pipe sections with »LBE..« type packing supports (please see Section 6»Column Components«) clamped between the ends provide a larger free cross-sectionthan the combination of column section and built-in packing support. Increased packed heights can be achieved by installing a pipe section on top of a columnsection.
Precision bore pipe sections with tight tolerances for chromatography columnsand special column internals are listed in Section 6 »ColumnComponents«.
The end form, which depends on the nominal size, is shown in thediagram on page 2.2. Further information can be found in Section 1»Technical Information«.

REDUCERSThere are both concentric and eccentric versions of these components available tocomply with the varying requirements encountered in practice. In DN 150 nominal size andabove the basic form of these components is hemispherical.
The concentric version should always be used for preference in vertical installations.
Eccentric reducers are very frequently used in horizontal pipelines where there is achange of bore to enable them to drain completely. There can also be a requirement forthis version for design reasons, e.g. where there is a change of lateral alignment.

In the case of fittings and shorter pipe sections (upto L = 500 mm) the jacket is one-piece and welded at both ends. On longer pipesections, because of differences in linear expansion between the inner component andthe jacket, we incorporate a split design with a flexible seal.
In addition to the standard components listed below, pipe sections of other lengths andlarger nominal sizes (up to DN 300 ) together with fittings up to DN 150 are also available.
The permissible operating conditions for the jacket and inner componentcan be found in Section1 "Technical Information”.
The branches on the jacket are of the QVF safety buttress end type. If theyare aligned horizontally with long or heavy hoses connected to them, werecommend 90º hose connectors to reduce the bending moment on thebranches.

3.2
VALVES & FILTERS
IntroductionQVF valves can be relied upon to require minimum maintenance and to provide maximum reliability in service. They are widely used in the chemical, pharmaceutical andallied industries together with other applications such as food and drink production, dye works and electroplating. This is because of the special properties ofborosilicate glass 3.3, PTFE, PFA, ceramic and tantalum plus the fact that borosilicateglass 3.3 is an approved and proven material of construction for pressure vessels.
Reference should also be made in this context to the extreme reliability of the improved,strong and high-duty coupling system used for all components. This is achievedthroughout the whole range of nominal sizes by the use of the safety buttress end whichhas been designed specifically by taking into account the properties of the materialcombined with a reliable flange system.
The complete range of standard valves is described on the following pages. Non-standard versions can also be supplied to special order where indicated in the productdescription.
A detailed listing of all valves by »Description« and »Catalogue Reference« can be foundin the »Index«.
Detailed information on a number of the topics referred to in the followingpages can be found in Section 1 »Technical Information«.
Metric grid modular systemThe valves described in this section comply with EN 12585 "Pipeline and Fittings,Compatibility and Interchangeability” and are conceived as a modular system. The onlyexceptions to this are »RKP..« non-return valves and »FVT..« butterfly valves. The basicunit of measurement is 25 mm and all component dimensions are a multiple of this basiclength. The resultant metric grid system facilitates trouble-free design and installation ofsystems with these components.
In addition valves and fittings (please see Section 2 »Pipeline Components«) in the samenominal size always have the same limb length, therefore the valves can be interchangedwith bends, tee pieces etc. This means that any modifications which may be requiredto existing pipelines can be carried out quickly and easily.
Sealing in Accordance with TA LuftThe former German regulation "Technical Manual for Clean Air" (TA-Luft) was amended,and the updated version came into force on 2004-07-24. It contains maximumpermissible limits for dust, steam, or gas emissions during the processing, conveying,or re-filling of dust, fluid, or gas materials.
TA Luft requires high-grade sealed metal bellows with a subsequent safety gland orequivalent sealing system for closing or control devices for the sealing of spindle feed-throughs. Equivalent sealing systems are deemed necessary if temperature-specificleakage rates are complied with during the proof procedure in accordance with VDI2440.
As metal bellows for QVF fittings are ruled out due to corrosion reasons, the equivalencetest was put to proof by TÜV Rhineland / Berlin-Brandenburg during the course ofdesign inspections.
All hand operated borosilicate glass 3.3/PTFE valves are, therefore, fitted with asecondary seal in addition to the basic bellows seal. Pneumatically actuated on/offvalves and control valves alone are available in two alternative versions. Butterfly valvesand ball valves are fitted with a secondary seal.
3.3
VALVES & FILTERS
Valves with PTFE bellows suitable for higher permissible operating pressurescan also be supplied on request.
Where different operating conditions apply to individual valves, the relevantdetails are provided in the respective product description.
GMP compliant installationsThe use of valves and the layout of interconnecting pipeline incorporating valves whendesigning plant and equipment complying with GMP regulations, calls for special carein both the planning and selection of the components, together with the materials ofconstruction used for them. Borosilicate glass 3.3 has a number of special propertiesthat are highly valued in the pharmaceutical industry, and these, in conjunction with PTFEmaterials (bellows, linings) approved in accordance with the FDA catalogue, ensure thatany build-up of unwanted deposits is avoided in areas which come in contact with theproduct. A design without any dead space, which ensures that components drain fullyand can be cleaned easily and effectively, is achieved in many valves by their shape andthe way they are installed. Where the external surfaces of these components have tocomply with clean room requirements, appropriate stainless steel coupling and supportmaterial can be supplied (please see Section 9 »Couplings« and Section 10 »Structuresand Supports«).
We would be happy to advise you on the basis of the regulatory requirements applicableto a particular case, and the guidelines drawn up by us, for the design of GMP compliantplant.
Coated valvesDamage to borosilicate glass 3.3 valves resulting from accidental external causescannot be entirely excluded, especially in the smaller nominal sizes. This is primarily dueto the relatively rigorous conditions prevalent in production plants and appliesespeciallywhere no additional protection is provided in the form of insulation.
Our answer to this problem is to provide borosilicate glass 3.3 valve bodies with aSectrans transparent coating. This can be applied irrespective of the shape of thecomponent and it provides additional protection without having any adverse effect onvisual monitoring of the process.
A glass fibre reinforced polyester coating providing a higher level of protection can alsobe supplied on request. This does have a slightly adverse effect on the transparency ofthe glass, making it translucent and not transparent.
Permissible operating conditions
While the maximum permissible operating temperature for borosilicate glass 3.3 valvebodies is generally 200 ºC (≥Θ •180 K) and their maximum permissible operating pressureis the same as for pipeline components of the same nominal size, the incorporation ofbellows imposes certain restrictions and the maximum permissible operating pressurefor the complete valve is somewhat lower. When the valves are used in plant applicationsthis is unlikely to be a problem since the maximum permissible operating pressure ofthe plant as a whole is governed bythe components with the largest nominal size.Detailed information on this and the peration of jacketed valves can be found in Section1 »Technical Information«.
3.4
VALVES & FILTERS
The design (bellows plug and seat shape) of the manually operated valves describedbelow is such that they can be used both as on/off valves and for the coarse regulationof liquid flow, for example in pump delivery lines. If required, on/off valves can also besupplied in the DN100 and DN150 nominal sizes but without regulating cone.
Manually operated control valves can be found on page 3.13 and on/off and controlvalves with pneumatic actuators are described from page 3.10 and 3.14.
These valves only act as regulating valves when the direction of flow is towardsthe cone.

JACKETED ON/OFF VALVESIn addition to pipe sections and pipeline fittings (see Section 2 »Pipeline Components«)jacketed valves with regulating plug can also be supplied for pipeline systems involvingtemperature control. Further versions of the valves described here are also available onrequest.
These jackets are one-piece and sealed at both ends. They are designed to ensure thatthe critical area in particular, i.e. the valve seat, can be maintained at a given temperature.The less critical pipe ends can be heated separately by a suitable method.
Details of the permissible operating conditions for the inner and outer area canbe found in Section 1 »Technical Information«.
The branches on the jacket are of the safety buttress end type. If they arealigned horizontally and if long hoses or heavy hoses are connected to them,we recommend 90º hose connectors to reduce the bending moment on thebranches.
In the case of the DN 15 angle valves the branches on the jacket are positionedturned through 90º to the front (DN 1) and back (DN 3) respectively.
Borosilicate glass 3.3 and metal hose connectors can be found in Section 2»Pipeline Components« and hoses in Section 9 »Couplings«.

The function of these valves is to ensure that flow in vertical pipelines can only be in one direction. The PTFE seat, ball and retaining plate provide excellent corrosion resistance.
Where there is an increased requirement for freedom from leakage these valves can besupplied on request with an O-ring gasket.
Ball-type non-return valves are not suitable for use as a long-term shut-offfunction.

BALL-TYPE NON-RETURN VALVES
These valves are used to maintain a constant pressure and are recommended for useafter dosing pumps. They may, however, also be used on occasions with centrifugalpumps (in this application it is more usual to use an orifice plate).
They can thus be used to deliver liquids safely, into or out of a vacuum, for example.Their use as by-pass valves in conjunction with dosing pumps prevents the build-up ofan unacceptably high pressure in the event of the pressure-side pipeline beinginadvertently closed off.
Unlike manually operated types, this valve has a spring the tension of which can beadjusted by a screwdriver. Thus, all intermediate values between 0.5 bars and thepermissible operating over-pressure may be set a tolerance range of ± 0.3 bar.
Please specify pressure setting on the order.
Care should be taken when operating these valves to ensure that the sum ofthe setting pressure and the pressure drop in the valve does not exceed themaximum permissible operating pressure of the pipeline.
Loading valves should not be used as pressure relief valves as they do not havethe necessary approval for such applications.

These valves are recommended for adjusting the interface in separators (e.g. in liquid-liquid extraction) azeotropic column heads or similar units. Level adjustment is infinitelyvariable and is by means of a PTFE tube fitted with sealing lips that can be moved upand down inside a precision bore glass tube.
Maximum possible throughputs (based on water and measured without any head in theinput) are indicated in the table below.
Horizontal separators with sealed-in adjustable overflow valve can be found in Section4 »Vessels & Stirrers«.
Technical Data
THREE WAY FLOW CHANGE VALVESWith normal three way valves it is possible to close both outlets at the same time bymistake which can result in the build-up of excess pressure in the line and also in theplant itself. The valve described here provides a safe solution to this problem since thedesign ensures that free flow through the valve is never impeded.
The use of a three way flow change valve is recommended when a plant is operatedbatchwise, under vacuum, and needs to be vented at regular intervals. In suchcircumstances one outlet is connected to the vacuum pump and the other (in reversedirection of flow) is used for venting purposes.
As in the case of on-off and control valves (please see page 3.10 and 3.14)three way flow change valves can be supplied with pneumatic actuators.

BOTTOM OUTLET VALVES
The »BAS40« is a short form valve, designed for use in spherical and cylindricalvessels which have short bottom outlets.
In the case of spherical and cylindrical vessels which have longer bottomoutlets, because they are jacketed or are for use in oil baths, the »BAL40« longversion should be used.
These fittings seal at the bottom side of the internal glass seat. The glass seat may beincorporated in spherical and cylindrical type vessels (see Chapter 4 »Vessels/Stirrers«).
For pneumatically actuated bottom outlet valves, please see page 3.19.
Versions which seal from above can also be supplied on request i.e. rising stem. Withthese valves a special inverted valve seat is required which must be specified whenordering the vessel. The plug is fitted from inside the vessel after the valve is attachedto the bottom outlet.
Valve with Drainage Nozzle
Valve for Integrated Drainage Nozzle
BOTTOM OUTLET VALVES
This fitting fully seals the bottom side of the melted glass joint dead space free. Theconvolutions of the bellow that experience product contact are manufactured to beround so that they also run empty if in an open state, and deliver good cleaningcapability.
The glass joint may be provided upon demand for spherical and cylinder type vessels.The joint with drainage nozzle is melted into the bottom of the vessel.
As PTFE tends to flow at high temperatures, QVF equips high-grade connections withspring elements. Two seals are performed in this drainage valve; the seal of the valvecasing, and the seal of the vessel floor. High sealing capability is ensured even for greattemperature deviations by employing this design principle.
The necessary valve length "H" is contingent to the deployed vessel (seeChapter 4, page 4-5).
This valve cannot be deployed for vessels of the type BAL/BAS.
In order to perform temperature measurements at the bottom nozzle of thevessel, valves with an integrated resistance thermometer of the type "PT100-,4-cable, class A - resistance thermometer with ATEX approval II 2G EEx e II"are on stock for delivery. In this case, the order number is supplemented by theletters "TH" in front of the nominal diameter (e.g. BASDTH25).
The valves are also available with a bonnet that includes an integrated stopagainst overturning (2 Nm).

PNEUMATICALLY ACTUATED BOTTOM OUTLET VALVEThis valve combines the valve body and bellows plug of the »BAS 40« manually operatedbottom-outlet valve with a Samson pneumatic diaphragm actuator. The length of travelof the sealing plug below the seat is 15 mm and this therefore leaves the entire flowcross-section free. The valve can be set to close or to open as required in the event ofa breakdown of the compressed air supply (please see below).
These valves are designed specifically for use with spherical or cylindrical vessels (seeSection 4 »Vessels & Stirrers«) or immersion heat exchangers (see Section 5 »HeatExchangers«) which have an integral glass-seat sealed into the bottom outlet. In the caseof spherical and cylindrical vessels this feature can be incorporated on request.
To provide a means of supporting the valves a »KK50-5« structure fitting (please seeSection 10 »Structures & Supports«) is provided on one of the yoke rods to facilitateattachment to the support structure.
Pneumatic actuators from other manufacturers, a long version based on the »BAL 40«and versions sealing from above can also be supplied on request. In the latter case thebellows plug has to be fitted from inside the vessel.
The supply pressure required is 2.5 bar g and this should not be exceeded bymore than 10 %.
When ordering please add a »1« to the catalogue reference if the »spring-to-open« fail-safe version is required or a »2« for »spring-to-close«.
If required the actuators can be supplied with the following additional built-onfeatures:
- Limit switch with built-in inductive proximity switches in accordance withEN 50227/IEC 61934, hazardous area type EEx ia IIC T6, to indicate if thevalve is open or closed.
- 3/2 way solenoid valve, hazardous area type EEx ia IIC T6 (24 V DC)..

VALVES & FILTERS
GAS MIXING VALVESThese valves are used to feed gas into bubble columns without internals and reactionvessels. The gas enters through holes drilled radially at the narrowest cross-section ofthe PTFE jet and the flow of liquid causes it to shear off into very fine bubbles. This alsoensures uniform distribution in the liquid even when used with large reaction vessels orsimilar equipment.
The liquid and gas throughput ratio can be selected within wide limits with the valve fullyopened. This is achieved by appropriate adjustment of the gas feed pressure, selectionof an appropriate diameter for the gas inlet holes or changing the liquid flow rate. It isalso possible to vary the ratio of the two flow rates to each other by adjusting the settingof the control cone.
A wide range of measurements have been carried out for the water/air system andgraphs recording the results of these are available on request. A summary of thesecurves can be seen in the diagram below.
The diameter of the gas inlet holes can be freely selected between 0.5 and 1.5mm in 1/10 mm increments.
When ordering, the required gas inlet hole diameter (please see below) shouldbe added to the catalogue reference.
The specification of the centrifugal pump is determined by the liquidthroughput on the one hand and the pressure drop in the valve and backpressure resulting from the column of liquid behind the valve on the other hand.
These valves should not be used as cut-off valves due to the risk of distortionof the gas inlet holes.

SAMPLING VALVESSampling Valves for Atmospheric and Positive Pressure
When taking samples from a vacuum, the vessels used (e.g. laboratory bottles)must be suitable for use under vacuum.
These valves are void of dead space and are designed for installation in horizontalpipelines. They are used to take samples from plant and other equipment. There are twodifferent versions (please see below and page 3.23) which should be selected accordingto whether they are to operate under positive or atmospheric pressure or alternatively,under vacuum.
The two-part sampling flange below the outlet neck has a PPH feed pipe fitted inside itand has a GL 45 screw thread (usual with laboratory glass ware). It will, therefore, accepta laboratory bottle (which is included in the supply), for example. It can also be ventedvia a hole provided in the flange. To evacuate the bottle when taking samples from avacuum, this hole is fitted with a three-way valve (G 1/4 connection).

BALL VALVES
The maximum permissible operating temperature for all versions is 180 °C. Themaximum permissible operating pressure is the same in each case as for thecorresponding size borosilicate glass 3.3 pipeline.
As a result of the careful selection of materials which ensures that they meet thecorrosion resistance standards expected of our products, these ball valves, which closewith a gas-tight seal, represent an excellent complement to the rest of our range of glassvalves. They are used in every type of application where full bore flow, i.e. low pressuredrop, is an important requirement. In addition, they offer the benefit of short operatingtravel.
All the various versions have the common features of a PFA-sheathed ball, PFA-sheathed stainless steel operating spindle and PTFE sealing ring (various designs). Bodymaterials, mating ends (with or without coupling components) and the sealingarrangements for the operating spindle vary.
All bodies (except »KH..«), coupling flanges and hand levers are epoxy resin coated.
Support fittings are available which consider the installation options for thesecomponents..

BALL VALVESCompact Ball Valves with Spheroidal Graphite CastIron/PFA BodyA feature of these compact ball valves with body and connecting flanges made ofspheroidal graphite cast iron/PFA (please see on page 3.24 for data on materials ofconstruction applicable to all versions) is their short overall length They are ideal for directinstallation in borosilicate glass 3.3 between components with safety buttress ends.Appropriately drilled type »CRSSE..« adaptor flanges (please see section 9 »Couplings«),inserts, bolts etc. should be ordered separately.
The operating spindle is sealed by means of a self-adjusting, maintenance-free stuffingbox.
PNEUMATICALLY ACTUATED BALL VALVES
Compressed air is required at 5.5 bar g for single-action actuators with the fullnumber of springs.
To avoid the sudden build-up of high surface pressure between the ball andoperating spindle at the start of the opening or shutting action, we recommendthe incorporation of air flow controls in the supply line to the actuator.
When ordering please add a »1« to the catalogue reference if the »spring-to-open« fail-safe version is required or a »2« for »spring-to-close«.
The »spring to open« setting can be changed to »spring to close« and vice-versa by changing the position of the operating spindle in the actuator by 90º.
If required, two inductive proximity detectors of hazardous area type EEx ia llC T6 to indicate on/off can be supplied for the actuators.
All the manually operated ball valves described above can be supplied with NORBROsingle-action actuators. Their spring return action can be set at will as a safety featureto either »spring to open« or »spring to close«.
Technical data and installation dimensions of these ball valves are the same as for themanually operated version.
The actuators themselves and the fitting kits used conform to ISO standards. Supportfittings are available which consider the installation options for these components.
If required, we can also supply actuators with a lower number of springs for lower airsupply pressures, double-action NORBRO actuators or actuators by othermanufacturers.

BUTTERFLY VALVES These valves, which close with a gas-tight seal, complement our ball valve range (pleasesee pages 3.24 to 3.26) in the larger bores. The combination of materials of constructionselected ensures that they also meet the corrosion resistance standards expected ofour products. They are used not only where there is a requirement for full bore flow, i.e.low pressure drop, and short operating travel, but also absence of dead space and shortoverall length.
In reaction units they can be used to separate the distillation overhead gear and reactionvessel when it is intended to operate the latter for periods at higher pressure.
These butterfly valves comprise essentially a PFA-sheathed stainless steeldisk/operating spindle unit, a two-part PFA / spheroidal graphite cast iron body, a maintenance-free, self-adjusting operating spindle seal together with a hand lever and an integral earthing strap for static electricity discharge purposes. The bodyand hand lever are epoxy resin coated.
As a result of their virtually equal percentage characteristic curve in the 20º to 80ºopening angle range, flap valves can also be used as control valves. The seal betweenthe disk and body lining is concentric and it makes a soft seal.
Support fittings are available which consider the installation options for thesecomponents.
Butterfly valves nominal size DN 50 are supplied as standard with a hand lever with fixedintermediate settings. Larger valves are supplied with a geared handwheel. All sizes can,however, be supplied with pneumatic actuators if required.
These butterfly valves can also be used for connections to glassed steelbranches. The corresponding sets of adaptors have to be ordered separately(see Section 9 »Couplings«).
The maximum permissible operating temperature is 190 ºC at -0,5/+4 bar gand 120 °C at -1/+4 bar g.
If required, butterfly valves can be supplied with an additional secondary seal(stuffing box), alarm connection and proximity switch (»valve closed« indicator).

VESSELS & STIRRERS
IntroductionQVF vessels and stirrers provide the optimum solution for every requirementencountered in practice because of the wide range of types available. Vessels in eitherbasic or jacketed form are essential components of many units and plants, both largeand small. They can be combined with various components such as vessel covers,stirrers, stirrer drives and heat exchangers to construct a widely varying range of stirredunits and reaction units. The range is supplemented by complete assemblies such asmobile vessels, horizontal separators and cyclones.
These components are widely used in the chemical, pharmaceutical and allied industriestogether with other applications such as food and drink production, dye works andelectroplating. This is because of the special properties of borosilicate glass 3.3, glass-lined steel and PTFE (gaskets) plus the fact that borosilicate glass 3.3 is an approvedand proven material of construction for pressure vessels.
Reference should also be made in this context to the extreme reliability of the strongand high-duty coupling system used for all components. This is achieved throughoutthe whole range of nominal sizes by the use of the safety buttress end which has beendesigned specifically by taking into account the properties of the material coupled witha reliable flange system.
The complete range of standard components and assemblies is described on thefollowing pages. Non-standard components that can be supplied to special order arereferred to in the respective product description.
A detailed listing of all components by »Description« and »Catalogue Reference« can befound in the »Index«.
Detailed information on a number of the topics referred to in the followingpages can be found in Section 1 »Technical Information«.
Details of the design of the different types of optimised buttress ends areillustrated alongside.
Immersion heat exchangers for spherical and cylindrical vessels can be foundin Section 5 »Heat Exchangers«.
GMP compliant installationsThe use of vessels, stirrers and stirrer drives and the layout of interconnecting pipelineincorporating valves, when designing plant and equipment complying with GMPregulations, calls for special care in both the planning and selection of the componentsused together with the materials of construction used for them. Borosilicate glass 3.3has a number of special properties that are highly valued in the pharmaceutical industryand these in conjunction with materials approved in accordance with the FDA catalogue,such as glass-lined steel (vessels, valves) and PTFE (bellows, lining, coating), ensure thatany build-up of unwanted deposits is avoided in areas which come in contact with theproduct. A design without any dead space, which ensures that components drain fullyand can be cleaned easily and effectively, is achieved by the shape of the components,the way they are installed and the selection of suitable valves. Where the externalsurfaces of complete assemblies have to comply with clean room requirements,appropriate stainless steel coupling and support material can be supplied (please seeSection 9 »Couplings« and Section 10 »Structures and Supports«).
We would be happy to advise you on the basis of the regulatory requirements applicableto a particular case and the guidelines drawn up by us, for the design of GMP compliantplant.

Glass components suitable for higher permissible operating conditions can besupplied on request.
Coated vesselsDamage to borosilicate glass 3.3 vessels and vessel covers resulting from accidentalexternal causes cannot be entirely excluded, especially in the smaller nominal sizes. Thisis primarily due to the relatively rigorous conditions prevalent in production plants andapplies especially where no additional protection is provided in the form of insulation.
Our answer to this problem is to provide borosilicate glass 3.3 vessels with a Sectranstransparent coating. This can be applied irrespective of the shape of the component andit provides additional protection without having any adverse effect on visual monitoringof the process.
A glass fibre reinforced polyester coating providing a higher level of protection can alsobe supplied on request. This does have a slightly adverse effect on the transparency ofthe glass , making it translucent and not transparent.
Permissible operating conditionsWhile the maximum permissible operating temperature for borosilicate glass 3.3 vessels,vessel covers and fittings is generally 200 ºC (∆Θ≤180 K), the maximum permissibleoperating pressure is governed by the main nominal size or the maximum diameter (spherical vessels only) of the component but not by its shape.Detailed information on this and the operation of jacketed components can be found inSection 1 »Technical Information«.
The permissible operating conditions for components in other materials can be foundin the respective product description.

Spherical vessels are commonly used not only as simple receivers and feed vessels butalso for stirred and reaction vessels as well as circulatory evaporators. Cylindrical vessels(please see page 4.9 to 4.12) can be used as a possible alternative as can jacketedglass-lined steel vessels as specified on pages 4.23 and 4.24.
Various items for use with spherical vessels can be found as follows: vessel covers andconnection flanges for stirrer drives on pages 4.18 to 4.20 and 4.42 glass and metalimmersion heat exchangers in Section 5 »Heat Exchangers«, heating mantles andheating baths on pages 4.31 to 4.33 and stirrers on page 4.35 onwards.
To cater for their wide variety of possible uses, spherical vessels are required with variousbottom and side branches (the top branch cannot be varied for manufacturing reasons).The illustration alongside shows the variations that occur most frequently and the tablebelow gives information about the range of possible side branch diameters.

JACKETED SPHERICAL VESSELSAs an alternative to heating the contents of spherical vessels in heating mantles (pleasesee page 4.31 ) or heating baths (please see pages 4.32 and 4.33) they can also besupplied up to a nominal capacity of 50 litre with a borosilicate glass 3.3 jacket. This iswelded to the vessel at both ends.
Due to their design, jacketed spherical vessels must be supported at the topbranch flange using tubular support frames.
If jacketed spherical vessels require a valve seat in order to fit a »BAL40« or»BAMD25« bottom outlet valve (please see Section 3 »Valves & Filters«) pleaseadd »BAL« or »BAMD« to the catalogue reference. For example »DVSM..BAL«or »DVSM..BAMD«.

The permissible operating conditions for the jacket and inner component canbe found in Section1 »Technical Information«.
Water or heat transfer fluids, can be used for heat transfer purposes. Ourengineers will be pleased to advise on this subject.
The branches on the jacket are the safety buttress end type. If they are alignedhorizontally and if long or heavy hoses are connected to them, we recommend90º hose connectors to reduce the bending moment on the branches.
Borosilicate glass 3.3 and metal hose connectors can be found in Section 2»Pipeline Components« and hoses in Section 9 »Couplings«.

CYLINDRICAL VESSELSThe version with full bore top neck can be used for a wide variety of purposes such asreaction vessels, separating vessels, receivers and feed vessels.
Cylindrical vessels with a reduced diameter top neck provide an economical alternativein some cases since they require a smaller vessel cover. These vessels are mainly usedas receivers.
Vessel covers for use with these cylindrical vessels can be found on pages 4.18 to 4.20.
Graduated and jacketed (up to DN 300 nominal size) versions can be supplied asstandard. Further information on these can be found on pages 4.11 to 4.15.
When cylindrical vessels require a valve seat in order to fit a »BAS40« or»BASD25« bottom outlet valve (please see Section 3 »Valves & Filters«) pleaseadd »BAS« to the catalogue reference. For example »VZ..BAS« or .»VZ..BASD«(dimension L increases in accordance with the table below).
Cylindrical vessels with a full bore top neck and nominal capacities of 5 to 10litre can be suspended from the upper backing flange. All other vessels shouldbe supported by the appropriate holder as described in Section 10 »Structures& Supports«.
All cylindrical vessels with reduced diameter top neck should be supported bya vessel holder (please see Section 10 »Structures & Supports«).

GLASS-LINED REACTION VESSELS
The internal pressure and temperature ratings are -1 to 1 bar g, and -60 to200 °C. The maximum working pressure of a complete reaction unit is dictatedby the pressure rating of the glass components selected for the overheadequipment. The vessels are capable of withstanding full vacuum.
The maximum operating pressure in the jacket is 10 bar g, with a temperaturerange of -60 to 200 °C. Higher pressures are available upon request.
The bottom outlet valve and the attachment bolts for the glass cover areincluded in the scope of supply.
In addition to jacketed glass vessels (see pages 4.8 and 4.13 to 4.15), these glasslinedvessels are also suitable for carrying out reactions with simultaneous heating or cooling.Additionally, due to their unique design, they form the basis for our standard series ofGMP reaction units.
They are supplied as standard with a main body flange of the same diameter as thereactor body, and are thus suitable for the use of both anchor and impeller-typeagitators. The jacket extends all the way up to the main flange, and is equipped withturbulence enhancing nozzles to maximise heat transfer performance. Either steam orthermal oil can therefore be used as the heating medium.
The vessels are designed for use with glass covers (see page 4.10), to permit constantvisual monitoring of the entire reaction process. The glass bottom outlet valve seats ontothe integral block flange at the base of the reactor, with minimum dead volume.
The glass foam insulation (in the VERI.. version) is sheathed in stainless steel, which iswelded top and bottom directly onto the reactor, to totally seal the insulation. The jacketsheath can also be supplied in a polished version on request. Non-insulated reactionvessels are fitted with angle plates to which the support brackets are attached. Forinsulated vessels, the support brackets are welded directly onto the insulation sheathing,thus providing a thermal barrier between the reactor and its supports.
Together with the agitator drives and agitators described on pages 4.35 to 4.45, thesereaction vessels form the basis of our Universal Reaction System. Standard fractionationcolumns, or overheads designed to meet your specific requirements, can also besupplied.
Upon request, we also offer Optimix type reactor vessels made of stainless steel and ofborosilicate glass up to 25 liters. On request, we also supply these reaction vessels inother materials such as stainless steel or hastelloy. If required, the vessel can also befabricated to a very high standard of internal finish, with ground welded seams and/orelectrolytically polished surfaces.

HORIZONTAL SEPARATORS
The end form, which depends on the nominal size, is shown in the diagramon page 4.2. Further information can be found in Section 1 »TechnicalInformation«.
The continuous separation of immiscible liquids with different densities requires low flowrates and the largest possible phase-interface between the light and heavy phase.Horizontal separators satisfy these requirements perfectly.
The separation layer is controlled by means of an adjustable overflow valve that can beinstalled either outside the separator (please see »OF..«, Section 3 »Valves & Filters«) orsealed into it (»AOF..«). The internals of the two types of overflow valve are identical for the same nominal size.
The table below indicates typical figures for maximum possible throughputs in theseseparators. These are based on water at 20º C and are measured without any head inthe input and can only be achieved up to the minimum density difference stated and forbuilt-in overflow valves. We would be pleased to provide an exact layout for you. Non-standard and intermediate sizes (up to DN 1000 and of different lengths), especially forsmaller density differences, can also be supplied upon request.

The borosilicate glass 3.3 coalescer illustrated on page 4.28 is a special feature and itconforms to GMP requirements. It is available in nominal sizes up to DN 300 and canbe incorporated into all horizontal separators and mixer-settlers. It is used to speed upcoalescence which would otherwise be very slow with fine dispersion (please requestspecial leaflet).

MIXER-SETTLERSMixer-settlers are used for extraction processes wherever there are great demands inflexibility on the operation of the plant. Frequently changing products, alterations to thenumber of stages required or wide variations in throughput can be decisive factors inthis decision process. A precondition for their use is, however, that only a restrictednumber of theoretical stages is required.
Scaling-up presents no problem since back-mixing effects can be excluded completelyby the clear separation of the light and heavy phases in each stage. When properly sized,each practical stage also corresponds approximately to a theoretical stage.
Each mixer-settler stage consists of a mixing chamber with a self-priming, variable speedstirrer as shown in the diagram below and a horizontal separator without a reducer onthe inlet end (please see »AOF..«, page 4.27), i.e. the two phases are mixed in each stagethen allowed to settle and separate from each other. The assemblies indicated, i.e. mixerand settler zone, are physically separated by a weir fitted within the flange coupling.
By connecting several mixer-settler stages in series and arranging for the phases to flowcountercurrent to each other, the plant can be adapted to handle the particularseparation problem in hand.

CYCLONESThe cyclones described here are designed for the separation not only of droplets fromgases and vapours but also of particulate solids from gases. The overall degree ofseparation can be as high as 99%, but this figure is governed to a very large extent bythe following parameters:
- Liquid loading of the gas or vapour or the solids loading of the gas
- Droplet or particle size range
- Droplet or particle size distribution
For the standard air/water system at ambient temperature and with a gas velocity of 15 m/s in the dip tube, limiting droplet diameters are approx. 2.5 µm for the DN 100 andDN 150 nominal sizes and approx. 3.5 µm for nominal sizes DN 200 and DN 300. Thepressure drop in these cases is in the region of 25 to 30 mbar.
We would be pleased to provide an exact design for the cyclone you require.

As an alternative to heating baths (please see pages 4.32 and 4.33) electric heatingmantles can also be supplied for spherical vessels. Their heating power varies accordingto the nominal capacity of the vessel involved.
These heating mantles are subdivided into several heating zones each of which isequipped with a temperature probe so that the surface temperature of the vessel canbe monitored. These work in conjunction with the control unit included in the supply toprevent local hot spots occurring. The control unit also includes energy regulators whichcan be used to control the heat input separately for each heating zone depending onthe liquid level.
For the heating mantle type HHW (version A), product temperature control is possiblevia an additional resistance thermometer (see Chapter 8 »Measurement/ControlDevices«). If no product temperature control is needed, or if such is performed by useof an existing contact thermometer, the heating mantle may also be delivered with asimple control device (type HHK, version B).
The number of heating zones and supply voltage of the heating mantles are indicatedin the table below.
If the heating mantle is to be used for a spherical vessel without abottom outlet or with a non-standard bottom outlet, the cataloguereference becomes »HH(W/K).., but for spherical vessel without bottomoutlet« or »HH(W/K).., but for DN .. bottom outlet« respectively. Themaximum nominal size for the outlet is DN100.
In view of the heat involved, a metal coupling must be used on thevessel’s bottom outlet (please see Section 9 »Couplings«).

HEATING BATHS FOR SPHERICAL VESSELSHeating baths can be used to advantage in applications where the materials beinghandled would tend to block or stick to the coils of immersion heat exchangers or wherethe use of heating mantles is not recommended. Options are available for heating eitherelectrically or with steam.
The spherical vessel sits on a support ring and a restraint prevents it from floating up. Astuffing box seals the bottom outlet to prevent leakage from the bath. The design alsoavoids imposing any stresses on the spherical vessel.
The baths are made of steel. The external surface is primed and painted.
The heat transfer fluid in the bath can be, for example, water of boiler feed water qualityor a synthetic oil. The bath temperature must always be a sufficient amount below theboiling temperature of the fluid. To ensure that this condition is met, the heating bathscan be fitted with suitable temperature control equipment if required.
Complete stainless steel heating baths and heating baths for cylindrical vessels can besupplied to special order.
Where it is necessary to ensure that the liquid in the bottom outlet is heated itis recommended to use spherical vessels with »BAL40« bottom outlet valve(please see Section 3 »Valves & Filters«).
HEATING BATHS FOR SPHERICAL VESSELSHeating Baths, Steam HeatedThe »BHKD..BAL« version is suitable for spherical vessels with sealed in seat for a»BAL40« bottom outlet valve, the »BHKD..E« version for spherical vessels with extendedbottom outlet (please see page 4.5).
The maximum permissible steam pressure in the heating coils is 10 bar g.
If required, a steam control valve, flexible hose and condensate separator can besupplied with these heating baths.

VESSELS & STIRRERS
STIRRER DRIVESVariable Speed Drive Assemblies with Bearing AssemblyThese assemblies incorporate a flange-mounted bearing assembly. This is fitted belowa variable speed drive motor and facilitates direct mounting of the complete drive unitonto a glass vessel cover. The drive spindle and stirrer shaft are connected inside thehousing by means of a clamp type coupling for smaller drives or muff type for largerdrives.
In order to meet the stirring duty, the speed can be varied from 0 up to the respectivemaximum via a manual hand wheel for these drive types. The setting can be changedwith the drive stopped or in operation. Before switching on the drive motor it should beset to its lowest speed.
As standard, electric motors are manufactured to protection type EEx e II T4 and EExde IIC T4, and for voltage connections of 230/400V, 3 phase, 50 Hz.
To facilitate supporting the drive unit in the structure, structure fittings and tubularstructures can be used (please see Section10 »Structures & Supports«). They are not included in the supply.
These stirrer drive units are designed for use with PTFE, glass coated steel and stainlesssteel stirrers with a shaft diameter of 44.5 mm.

The stirrers (suffix ..SAT) with single-acting mechanical seals are approved for operationswithin zone 0 (category 1) inside the vessel, and for zone 1 (category 2) outside thevessel in accordance with EU directive 94/9/EG (ATEX).
The mechanical seals operate on a SIC/hard-carbon sealing surface, and conform toFDA requirements. An integrated-temperature measuring device built into the sealingplate, which is a requirement for regulation-conform operations, monitors the maximumtemperature within the mechanical seal. For use within the temperature class T4, thetemperature rating is 100°C, for T3 it is 150°C.
ATEX Version with Double Mechanical Seal Protection Type II 1/2 G c b II T4
The stirrers (suffix ..AT) with double acting fluid-lubricant mechanical seals are approvedfor operations within zone 0 (category 1) inside the vessel, and for zone 1 (category 2)outside the vessel in accordance with EU directive 94/9/EG (ATEX).
The mechanical seal operates on a PTFE/ceramic sealing surface.
The installation of a cooled lubricant circulation is required to conform to regulations andfor which the sealing liquid level within the vessel and the sealing media temperature(as measured within the mechanical seal casing) shall be monitored, contingent to theabove rating.
Temperature monitoring may be omitted if the stirrer is only deployed within zone 1(category 2) inside the vessel.
If the maximum sealing media temperature is held at 50°C, use is possible at producttemperatures ranging up to 200°C.If used at temperature class T4, the maximum producttemperature shall not exceed 108°C; for T3, it shall not exceed 160°C.
The length L of the stirrer is extended by 90 mm compared to the single-actionmechanical seal, along with the overall length for the drive.

DRIVES WITH FREQUENCY CONVERTERS
Drives for Frequency InverterThis type of drive can be used whenever variations in speed are achieved by means ofa frequency inverter. The flameproof electric motor is fitted with the required thermistorsas standard. These drives can also be used to drive stirrers at a fixed speed (750 rpm),this can however cause problems on start-up. Such a solution should, therefore, onlybe adopted in exceptional cases.
The drive shaft and stirrer blade are also connected to each other via a clamp couplingwithin the lantern, just as the variants with gear motor.
The electric motors, which have a minimum speed of 75 rpm, are supplied withprotection type EEx de llC T4 and for a 230/400 V, 3 phase, 50 Hz supply. It shall beobserved that the small torque available at low turning speed can lead to difficulties fortough media or tasks.

THERMOSIPHON UNITSThese units work on the thermosiphon principle. We always recommend using them inconjunction with double mechanical seals whenever handling substances that are toxicor highly corrosive, that contain abrasive components or that have a tendency tocrystallise. The barrier fluid, which should be chosen on the basis of its compatibility withthe product, carries out three functions necessary for trouble-free operation: it acts asa barrier, provides lubrication and keeps the unit cool. It is covered by a gas buffer,pressurised to suit the operating pressure in the reaction vessel.
Thermosiphon units are supplied with or without a top-up unit to maintain the barrierfluid level during operation. This cannot be retrofitted.
Type »THAO..« (without top-up unit) comprises a vessel with an internally fitted coolingcoil in stainless steel, pressure gauge and sight glass together with the fittings necessaryfor connection to the mechanical seal including 4 m stainless-steel clad hose. Type»THAP..« (with top-up unit) comprises the same items plus an additional vessel and abuilt-on hand-pump. The parts in contact with the product are also made of stainless steel.

The adaptor flange, insert and fixings are included in the supply.
The PTFE used in the manufacture of these stirrers is carbon filled.
Conductive material may be delivered upon request.
For construction reasons the maximum possible stirrer length is limited to 1800 mm.
PTFE STIRRERSThe different shapes of vessel (spherical or cylindrical vessels) on the one hand and theduties to be carried out on the other (suspension, homogenisation, with or withoutsimultaneous heat transfer etc.) determine the type of stirrer to be used. Their design(propeller or turbine) is another factor influencing the need or otherwise for a baffle tocreate turbulence. Further information can be found with the individual types of stirrer.
These two-piece stirrers consist of a PTFE-sheathed shaft and a PTFE stirrer elementwith steel core that is attached to the shaft to prevent twisting. A perfect seal ismaintained between the two parts over the whole permissible temperature range (-50 to +150 ºC).

HEAT EXCHANGER
IntroductionQVF heat exchangers provide the optimum solution for every requirement encounteredin practice because of the wide range of types available. This applies not only to coiltype heat exchangers, which are available as condensers, boilers and immersion heatexchangers, but also to shell and tube heat exchangers, which are designed for use withtubes in the widest possible range of corrosion resistant materials.
These items are widely used in the chemical, pharmaceutical and allied industriestogether with other applications such as food and drink production, dye works andelectroplating. This is because of the special properties of borosilicate glass 3.3 and allthe other materials used plus the fact that borosilicate glass 3.3 is an approved andproven material of construction for pressure vessels.
Reference should also be made in this context to the extreme reliability of the strongand high-duty coupling system used for all components. This is achieved throughoutthe whole range of nominal sizes by the use of the safety buttress end which has beendesigned specifically by taking into account the properties of the material coupled witha reliable flange system.
The complete range of standard heat exchanger components is described on thefollowing pages. Non-standard components that can be supplied to special order arereferred to in the respective product description.
A detailed listing of all heat exchangers by »Description« and »Catalogue Reference« canbe found in the »Index«.
Detailed information on a number of the topics referred to in the followingpages can be found in Section 1 »Technical Information«.
Details of the design of the different types of optimised buttress ends areillustrated alongside.
GMP compliant installationsThe use of heat exchangers and the layout of interconnecting pipeline incorporatingvalves when designing plant and equipment complying with GMP regulations, calls forspecial care in both the planning and selection of the components used together withthe materials of construction used for them. Borosilicate glass 3.3 has a number ofspecial properties that are highly valued in the pharmaceutical industry and these inconjunction with materials approved in accordance with the FDA catalogue, such asPTFE (bellows, lining, coating), glass-lined steel (heat exchanger shells) and specialmaterials (silicon carbide etc.) ensure that any build-up of unwanted deposits is avoidedin areas which come in contact with the product. A design without any dead space,which ensures that components drain fully and can be cleaned easily and effectively, isachieved by the shape of the components (e.g. coil and circular ring type heatexchangers) and the way they are installed. Where the external surfaces of thesecomponents have to comply with clean room requirements, appropriate stainless steelcoupling and support material can be supplied (please see Section 9 »Couplings« andSection 10 »Structures and Supports«).
We would be happy to advise you on the basis of the regulatory requirements applicableto a particular case and the guidelines drawn up by us for the design of GMP compliantplant.

HEAT EXCHANGER
Glass components suitable for higher permissible operating conditions canalso be supplied on request.
Coated heat exchangersDamage to borosilicate glass 3.3 assemblies resulting from accidental external causescannot be entirely excluded, especially in the smaller nominal sizes. This is primarily dueto the relatively rigorous conditions prevalent in production plants and applies especiallywhere no additional protection is provided in the form of insulation.
Our answer to this problem is to provide borosilicate glass 3.3 heat exchangers with aSectrans transparent coating. This can be applied irrespective of the shape of thecomponent and it provides additional protection without having any adverse effect onvisual monitoring of the process.
A glass fibre reinforced polyester coating providing a higher level of protection can alsobe supplied on request. This does have a slightly adverse effect on the transparency ofthe glass, making it translucent and not transparent.
Permissible operating conditionsWhile the maximum permissible operating temperature for borosilicate glass 3.3 heatexchanger bodies is generally 200 ºC (∆Θ ≤ 180 K), the maximum permissible operatingpressure is governed by the main nominal size of the component but not by its shape.Detailed information on this can be found in Section 1 »Technical Informaton«.
The maximum permissible figures for pressure and temperature gradient across the heatexchange surfaces and PTFE tube plates (between the media) and the permissibleoperating conditions for components in other materials can be found in the respectiveproduct description.

HEAT EXCHANGER
Unlike the shell and tube heat exchangers described on pages 5.15 to 5.22 theseitems have the coil battery welded to the jacket. This is of importance for plant whichhas to conform to GMP requirements since it ensures that the product and thecoolant cannot come into contact with each other.
Coil type heat exchangers are mainly used as condensers or coolers. They can,however, be used for heat transfer between liquids and gases in general. Turbulent flowis ensured even in the larger nominal bores since the coil layers are offset and fill the flowcross-section to a great extent.
Information on pressure drop in the coils together with performance data which can beused to estimate the heat transfer surface required can be found on pages 5.6 and 5.7.We would be happy to carry out detailed design work for you.
The permissible pressure difference across the wall of the coils as a functionof the temperature difference at that point is indicated in the diagram below.The specified DQ is the difference between the temperature of the shell sidemedium and the medium inside the coils. The permissible pressure differenceis valid up to an overall heat transfer coefficient of U=290 Wm-2 K-1 wich coversmost practical applications.
COIL TYPE HEAT EXCHANGERS
Permissible pressure difference between coil and jacket as a function of thetemperature difference between the products in the two areas.
The inlet and outlet connections are of the safety buttress end type. If they arealigned horizontally and if long or heavy hoses are connected to them, werecommend 90º hose connectors to reduce the bending moment on thebranches.
When installing coil-type heat exchangers appropriate precautions should betaken. Details of these can be found in the installation and operatinginstructions enclosed with each item. The main points to be taken into accountwhen planning to use these items as coolers are (see also flow chart below):
5.5
HEAT EXCHANGER
COIL TYPE HEAT EXCHANGERS- The use of hoses or bellows on the cooling water connections to avoid
imposing stresses.
- Fitting a pressure reducing valve (if necessary), control valve, non-return valve (not when used under re-cool conditions) and pressure gauge immediately before the heat exchanger.
- Free drainage of the cooling water from the coils, if it is not possible to provide other means of ensuring that the permissible operating pressure (see page 5.4) is not exceeded.
- Ball valves or other rapid opening valves must not be used in the inlet lines to coil type heat exchangers to avoid any water hammer in the coil.
Up to DN 150 nominal bore coil type heat exchangers can also be installedhorizontally (with a slight fall).
The end form, which depends on the nominal size, is shown in the diagram onpage 5.2. Further information can be found in Section 1 »Technical Information«.

For approximate calculation of evaporation performance the heat transferred in all sizescan be considered on average as 400 Wm-2 K-1 with a steam pressure in the coils of 3.0 bar g. This figure declines marginally at lower pressures.
The table below shows figures calculated on this basis for the evaporation of water withan inlet temperature of 100 ºC and at atmospheric pressure (if the feed is cold, theperformance of the boiler will be only about 80% of the figures quoted):
- The use of hoses or bellows on the steam and condensate connections to avoid imposing stresses.
- Provision for sufficient fall on the steam inlet and condensate outlet lines.
- Fitting a pressure reducing valve (if necessary), control valve and pressure gauge immediately before the boiler and a reliable system to clear condensate with a by-pass valve (for use during start-up) immediately after the boiler.
- Ball valves or other rapid opening valves must not be used in the inlet lines to coil type boilers to avoid any pressure hammer in the coil.
Coil type boilers should not be fitted at the bottom of columns or vessels, sinceadequate circulation cannot be guaranteed in such locations. Delay in boilingcan occur which in turn may result in breakage of the coil.

IMMERSION HEAT EXCHANGERSThis type of heat exchanger is predominantly used in vessels to heat or cool productsin conjunction with stirring duties. Suitable vessels are spherical vessels with largebottom outlet (similar to type »VSH..«) or cylindrical vessels with a bottom outlet ofappropriate nominal size which can also be supplied on request.
Performance data which can be used to estimate the heat transfer surface required canbe found at the end of this section. We would be happy to carry out detailed designwork for you.
The inlet and outlet branches are of the safety buttress end type. Borosilicateglass 3.3 and metal hose connectors can be found in section 2 »PipelineComponents« and steam hoses, which can also be used on the condensateside, in section 9 »Couplings«.
When installing immersion heat exchangers appropriate precautions should betaken. Details of these precautions can be found in the installation andoperating instructions supplied with each item.

SHELL AND TUBE HEAT EXCHANGERSShell and tube heat exchangers provide a versatile alternative to the coil-type heatexchangers described on previous pages. They were conceived as condensers, but theyare equally suitable for heat transfer between two liquids or gases.
These shell and tube heat exchangers are of modular construction. They comprise thefollowing individual elements: tubular shell, headers, tube plates, heat exchange tubesand baffles. Sealing of the individual tubes in the tube plate is of particular importance.The threaded PTFE bushes and PTFE sealing rings provide a seal of the highest integritybetween the different materials.
Four basic versions of shell and tube heat exchanger, with PTFE tube plates andborosilicate glass 3.3 or silicon carbide heat transfer tubes, are available as standard.They are listed on pages 5.16 to 5.19.
Performance data which can be used to estimate the heat transfer surface required isgiven on page 5.21. We would be happy to carry out accurate calculations for you usingspecial programs.
The maximum permissible operating conditions in borosilicate glass 3.3 heatexchangers are detailed in the table below. If duties in excess of these figuresare called for, we recommend the use of the special versions described onpage 5.22.
The standard branch positions are as indicated in the appropriate diagrams.Alternative positions are available on request.
When making connections to the service necks on the heat exchangers,bellows should be used to avoid imposing any stresses.
When installing shell and tube heat exchangers appropriate precautionsshould be taken. Details of these can be found in the installation and operatinginstructions supplied with each item.
The standard version of these heat exchangers is designed to be installedhorizontally. If required, however, drain and venting facilities can be providedon the tube plates together with changes to the support arrangements on theunits to permit vertical installation (please see page 5.20).
The end form, which depends on the nominal size, is shown in the diagramon page 5.2. Further information can be found in Section 1 »TechnicalInformation«.

SHELL AND TUBE HEAT EXCHANGERSShell and Tube Heat Exchangers, special versionsBecause of the modular design of the standard heat exchangers (see page 5.15), a widevariety of alternative materials can also be supplied and this facilitates adaptation of theheat exchangers to the particular requirements of each case. Details can be found inthe table below and our special brochure which is available on request.
Additional features which can be supplied on request are:
- Turbulence devices for fitting in the heat exchange tubes. These increase heat transfer in the tubes by up to three times the normally attainable value.
- Double tube plates that ensure trouble-free separation of the shell-side and tube-side pressure area. Risks caused by leakage, for example the contaminationof the product by the heating or cooling fluid, are thus avoided. This is of importance above all else for plant which has to conform to GMP requirements.

HEAT EXCHANGER
METAL - IMMERSION HEAT EXCHANGERSBayonet Type - Immersion Heat ExchangersThere is a very wide range of applications for this type of heat exchanger, particularlywhere a high level of corrosion resistance is required. Typical applications include useas boilers in circulatory evaporators and for heating columns. The design incorporatingmultiple bayonets ensures good heat transfer even when larger heat transfer surfacesare involved.
Bayonet immersion heat exchangers can be supplied in nominal sizes DN 80 to DN 600with heat transfer areas from 0.05 to 8.5 m2.
The base of these boilers is designed to act as a vapour distributor and condensatecollector. A branch drilled to suit QVF PCD hole size and number welded through thebase serves as a product connection. Hoses can be supplied for the steam andcondensate connections (please see chapter 9 »Couplings«).
Bayonet immersion heat exchangers are supplied in tantalum as standard. Othermaterials are, however, also available.
The maximum permissible operating pressure for bayonet immersion heatexchangers is 10 bar g and the maximum operating temperature is 210 ºC (PN40 steam and condensate connection, EN 1092 ).

COLUMN COMPONENTS
IntroductionQVF column components provide the optimum solution for every requirementencountered in practice for operations such as distillation, rectification, absorption,reaction and extraction because of the wide range of different components available.This applies not only to the various types of column and pipe sections available (plainand jacketed and with or without internals) but also to the wide selection of internalsand random and structured packing that can be supplied.
These components are widely used in the chemical, pharmaceutical and allied industriestogether with other applications such as food and drink production, dye works andelectroplating. This is because of the special properties of borosilicate glass 3.3 andPTFE together with the special materials that are used in some instances for internals,plus the fact that borosilicate glass 3.3 is an approved and proven material ofconstruction for pressure vessels.
Reference should also be made in this context to the extreme reliability of the strongand high-duty coupling system used for all components. This is achieved throughoutthe whole range of nominal sizes by the use of the safety buttress end which has beendesigned specifically taking into account the properties of the material, coupled with areliable flange system.
The complete range of standard column components is described on the followingpages. Non-standard components can also be supplied to special order. Columnsections and fittings in other materials (glass-lined steel etc.) can also be supplied onrequest.
A detailed listing of all column components by »Description« and »Catalogue Reference«can be found in the »Index«.
Detailed information on a number of the topics referred to in the followingpages can be found in Section 1 »Technical Information«.
Further information on complete columns can be found in our special leafletsdealing with individual unit operations.
Details of the design of the different types of optimised buttress ends areillustrated alongside.
GMP compliant installationsThe use of columns and the layout of interconnecting pipeline incorporating valves whendesigning plant and equipment complying with GMP regulations, calls for special carein both the planning and selection of the components together with the materials ofconstruction used for them. Borosilicate glass 3.3 has a number of special propertiesthat are highly valued in the pharmaceutical industry and these in conjunction withmaterials approved in accordance with the FDA catalogue such as glass-lined steel(special versions of large bore column bottom sections), PTFE (redistributors andpacking retainers) and special materials (e.g. internals) ensure that any build-up ofunwanted deposits is avoided in areas which come in contact with the product. A designwithout any dead space, which ensures that components drain fully and can be cleanedeasily and effectively, is achieved by the shape of the components, the way they areinstalled and the selection of suitable valves. Where the external surfaces of completeassemblies have to comply with clean room requirements, appropriate stainless steelcoupling and support material can be supplied (please see Section 9 »Couplings« andSection 10 »Structures and Supports«).
We would be happy to advise you on the basis of the regulatory requirements applicableto a particular case and the guidelines drawn up by us for the design of GMP compliantplant.

COLUMN COMPONENTS
Glass components suitable for higher permissible operating conditions can besupplied on request.
Coated column componentsDamage to borosilicate glass 3.3 plant resulting from accidental external causes cannotbe entirely excluded. This is primarily due to the relatively rigorous conditions prevalentin production plants and applies especially where no additional protection is providedin the form of insulation.
Our answer to this problem is to provide borosilicate glass 3.3 column components witha Sectrans transparent coating. This can be applied irrespective of the shape of thecomponent and it provides additional protection without having any adverse effect onvisual monitoring of the process.
A glass fibre reinforced polyester coating providing a higher level of protection can alsobe supplied on request. This does have a slightly adverse effect on the transparency ofthe glass, making it translucent and not transparent.
Permissible operating conditionsWhile the maximum permissible operating temperature for all borosilicate glass 3.3column components is generally 200 ºC (∆Θ • 180 K, the maximum permissible operatingpressure is governed by the main nominal size of the component but not by its shape.Detailed information on this and the operation of jacketed components can be found inSection 1 »Technical Information«.
The permissible operating conditions for components in other materials can be foundin the respective product description.

COLUMN COMPONENTS
Depending on the nominal size, column sections are supplied in 1000 and/or 1500 mmlengths, and also with or without a thermometer branch. They have an integral shelf onwhich the packing support rests. A PTFE ring is fitted between the support shelf andpacking support to prevent direct contact between the two parts.
Column sections can be filled with random packing or alternatively structured packingif the free cross sectional area of the packing support is large enough (please see page6.5), For structured packing higher free cross sectional areas can be achieved by theuse of »CSDU..« type column sections (please see page 6.12).
Higher free cross-sectional areas can be achieved in the DN 80 to DN 300 nominal sizerange by combining pipe sections (please see section 2 »Pipeline Components«) with»LBE..« type packing supports (please see page 6.8). Use of pipe sections and specialtypes of support plates is possible across the whole range of nominal sizes. For largerdiameters, the patented support CORE-TRAY is available, which also serves as fluidcollector and distributor. Column sections with structured packing, such asDURAPACK® high performance borosilicat glass 3.3 packing, described on page 6.12are an example of this type of application.
Pipe sections can also be used to extend the length of column sections i.e. to increasethe packed height, provided the permissible load-bearing capacity of the packingsupport is not exceeded.
Column sections suitable for installing distribution plates as well as packing retainers aredescribed on pages 6.6 and 6.10. Precision bore pipe sections with and withoutbuttress ends for special internals or chromatography columns can be found on page6.32.
Jacketed column sections can also be supplied on request.
All column sections are supplied complete with a packing support. Randompacking (please see page 6.9) and structured packing (please see page 6.10and 6.11), should be ordered separately.
Details of free cross-sections (including packing support), the load-bearingcapacity of the support rings in conjunction with the supplied packing supportsand the recommended packing can be found in the table on the followingpage. The free cross-section of individual components used to constructcolumns and the load-bearing capacity of the packing supports is indicatedin the description of the product in question.
The minimum size of random packed or stacked raschig rings can also befound in the table on the following page. Where raschig rings of smaller sizesare used a layer of high performance DURAPACK® should be installed first.
In the table below »DN« refers to the nominal size of the column.
For manufacturing reasons on column sections in DN 800 and DN 1000nominal sizes in which the support shelf also acts as a redistributor thethermometer branch can only be located below the upper buttress end.

Mass transfer in absorption, desorption, rectification and extraction columns can beimproved by the use of structured packing in various materials. They provide highthroughput coupled with low pressure drop and at the same time ensure goodseparation efficiency.
The DURAPACK® borosilicate glass 3.3 mass transfer packing referred to herecombines these benefits with the ability to handle very corrosive and/or high purityproducts. Further information such as areas of application, pressure drop, separationefficiency and flooding point can be found in our special brochure "DURAPACK®Borosilicate Glass 3.3 Structured Mass Transfer Packing”.
Complete couplings with longer bolts are required for column sections withstructured packing installed, this is because of the support rings and packingrestraints clamped between the flat buttress ends. These can be found in thesection 9 »Couplings«.

DURAPACK®-ElementsSTRUCTURED PACKING
On request we can also supply DURAPACK® elements in different sizes or forlarger diameters (e.g. glass-lined columns) as well as structured packing inother materials of construction.
The installation of DURAPACK® mass transfer packing calls for considerableexperience and requires a certain amount of fitting work (make-up rings,retainers, drilling of holes for measurement probes). Any elements suppliedincluding accessories should, therefore, only be installed by our trainedinstallation personnel on the actual site. The maximum packing height shouldnot exceed 3 metres.
Where the packing elements are not intended for use in glass pipes, pleaseconsult us because of the possibility of varying diameters and the possibleneed for adaptation of the edge seal.

Support rings are generally used to support structured packing such as highperformance DURAPACK® packing (please see pages 6.10 and 6.11) in pipe sections.Up to DN 300 nominal size they are made of selected quality PTFE. In larger nominalsizes PTFE-sheathed steel rings are used. These also act as a support flange for thecolumn section. In the DN 800 and DN 1000 nominal sizes there is also the alternativepossibility to combine the support ring with a fixed-point flange with the latter supportedon a steel angle substructure. Further information to this can be found in section 10»Structures and Supports«.
Support rings are clamped between the buttress end faces using longer bolts in thecoupling. The rings have a bead on both faces, so that no additional gasket is required.

Structured packing such as high efficiency DURAPACK® packing (please see page6.11) must always be very carefully fixed after installation in column sections. Otherwisethere is the risk of relative movement between the jacket and the internals should anypressure surges occur which could result in damage to the packing elements withconsequent loss of performance or even disruption of operation.
For this reason, one or more spacer rings should be inserted above a section ofstructured packing to fill any free space between the internals and a restrainer (pleasesee below) clamped between the buttress ends in the upper coupling. These spacerrings are made of selected quality PTFE.
It is advisable to have a variety of rings available in different thicknesses to ensure thatthe free space can be filled to optimum effect.

SPRAY FEED SECTIONS WITH BUILT-IN FEED PIPEWhere there is a requirement for a finer initial distribution of the liquid stream than canbe obtained with a column feed pipe (please see page 6.17) a spray feed section withbuilt-in feed pipe can be used in the DN 100 to DN 300 nominal size range. Thiscomponent delivers the liquid to the column in the form of a ring. Spray feed pipes forDN 450 and DN 600 nominal size columns can be found below.
These one-piece components comprise an unequal tee piece with a fused-in spray typefeed pipe. They make it possible to use a spray type feed even in small and medium sizecolumns.

For DN 450 and DN 600 nominal size columns these spray feed pipes are used insteadof column feed pipes to provide a finer initial distribution of the liquid stream in the formof a ring. A version suitable for smaller columns can be found above.
This design, which can only be used with larger column sizes, facilitates the fitting andremoval of the spray feed pipe without the need for any extensive dismantling work. Thismakes adaptation to changes in operating conditions a very simple matter.
For more specialised requirements tray, tube and nozzle type distributors can besupplied (please see pages 6.19 to 6.23).

LIQUID DISTRIBUTORS To create the conditions required for optimum mass transfer in larger nominal sizecolumns through even distribution, we recommend the use of special components bothfor the first feed distribution and also redistribution in the column. Depending on theparticular duty we can supply borosilicate glass 3.3 column components with sealed-intube and channel type distributors as well as nozzle type distributors in a combinationof borosilicate glass 3.3 and PTFE. The latter are fitted in distributor sections (please seepage 6.23) for feed distribution duties or for use as redistributors in special columnsections (please see page 6.6).
The following criteria have an important bearing on the selection of the appropriate liquiddistributor:
– Process conditions such as pressure, temperature, F factor and irrigation density Bmax
– Column diameter and type of packing
– System properties where a distinction should be made between clean (C=clean) and slightly soiled (S=soiled) systems
Liquid distributors can be selected from the table below on the basis of the nominal sizeof the column, irrigation density and system properties. Further data can be found in theindividual product descriptions.

Channel Distributors
Technical Data
Where good distribution of the liquid over the whole cross section of the column isrequired with low irrigation densities we recommend the use of a channel distributor. Theitems described here are especially suitable for feed distribution of the liquid with all typesof structured packing. On request, we can also supply them with an integral collectingtray for use as redistributors.
Channel distributors are one-piece borosilicate glass 3.3 components which can befitted in columns without the need for any special adaptation. The liquid flows throughdrilled holes aligned in a downward direction and also through overflow pipes. The latterstart to work from 40% (stage 2) or 75 % (stage 3) respectively of the maximum irrigationdensity onwards.
In the event of overloading, the liquid backs up along the whole length and runs off overthe channel edges ensuring that irrigation of the column cross section is achieved overa large surface. Good drainage of any remaining liquid is ensured by appropriate sizingof the draining holes.
Special versions of these distributors can be supplied on request, i.e. with drop pointsdiffering from those indicated in the table below (diameter and number of holes andoverflow pipes) and also in nominal sizes DN 800 and DN 1000.

Nozzle distributors for feed distribution
Technical Data
This type of distributor is ideal for high irrigation densities and widely varyingthroughputs. Good distribution of the liquid over the column cross section is ensured inboth cases.
Nozzle distributors for feed distribution are a combination of borosilicate glass 3.3 andPTFE (nozzles only). The nozzles have lateral slits and are inserted separately in asupport tray. They can, therefore, be replaced if required. The tray in turn is located onthree support fingers positioned at 120º to each other and adjustable by means of aflexible gasket (see section 9 »Couplings«). A PTFE ring is fitted to prevent direct contactbetween the tray and the support fingers. Holes are designed to ensure good drainagewhen empty.
When a nozzle distributor is used for redistribution purposes an »RDA..« type refluxseparator should be fitted above it with the inlet branch DN1 closed off. As an alternativewe can supply the nozzle distributors described on page 6.23 which can be installed indistributor sections or column sections specially designed for the purpose.

Manually Operated Reflux Separators
Reflux separators are used to control the reflux ratio in rectification columns, i.e. toseparate the condensate produced into reflux and take-off streams. There are variousversions available. In the manually operated version the off-take is adjusted by meansof a valve on the outlet connection. The electromagnetically and pneumatically operatedversions are automatically controlled in conjunction with a timer (please see section 8»Measurement & Control«).
In these units the reflux is adjusted by means of a manually operated valve on thedistillate outlet connection. When the valve is fully open the divider is set to total off-take,as the return pipe is located higher than the outlet connection. By regulating the valve,the reflux ratio can be continuously adjusted up to total reflux.
If a specific and reproducible reflux ratio is required, the use of an automatically operatedreflux divider is recommended.
The end form, which depends on the nominal size, is shown in the diagramon page 6.2. Further information can be found in section 1 »TechnicalInformation«.

COLUMN COMPONENTS
REFLUX SEPARATORSElectromagnetically Operated Reflux Separators - InternalThis type of reflux separator uses a swinging funnel mechanism. The funnel, which hasa soft iron core sealed into it, is operated magnetically from outside the column by meansof a timer. When the electromagnet is not energised the funnel is at rest and all thecondensate is returned to the column. Activation of the electromagnet moves the funnelinto the off-take position and the distillate is removed from the column via the off-takebranch.
The electromagnet and timer (see section 8 »Measurement & Control«) shouldbe ordered separately.
To prevent vapour entering the distillate line, a liquid seal (please see page6.28) should always be used on the off-take line.

Technical Data
There are two different versions of columns with bubble cap plates available withborosilicate glass 3.3/PTFE/tantalum bubble-caps or with stainless steel bubble-caps(please see page 6.31). The actual column section is borosilicate glass 3.3 in both cases.
Column sections specifically designed for the purpose are used to provide correctsupport for the plates, to ensure that they are firmly fixed on the underside and to ensurea permanently reliable edge seal. This is achieved by reducing the cross-section of theouter jacket within sufficiently close tolerances at the appropriate points and using aPTFE sealing ring. The glass plates and sealing rings are also braced within the columnby means of tantalum hooks as protection against pressure surges.
The standard bubble-caps supplied have a relatively low pressure drop. These bubble-caps can, however, be supplied with risers on, as these are better suited for use asscrubbers which are downstream of batch processes. This ensures that the scrubbingliquid is retained on the plates when vapour flow is halted for short periods.
Glass pipes are used as downcomers, with a cross-section selected for the liquidloading for the particular application. The bottom column section requires a downcomerfitted with a dip pot to provide a liquid seal. Both versions, i.e. with and without dip pot,can be found in the table below
Further information on column sections with bubble-caps such as areas of application,operating range, flooding point and pressure drop can be found in our special brochure"Column Sections with Random and Structured Packing and Internals”.

There are two different versions of columns with bubble cap plates available: withstainless steel bubble-caps or with borosilicate glass 3.3 bubble-caps (please see page6.30). The actual column section is borosilicate glass 3.3 in both cases.
The stainless steel bubble-cap internals are completely preassembled and thenintegrally fitted into precision bore borosilicate glass 3.3 pipe sections so that theirperformance can be visually monitored at all times. The seal between the bubble-capplates and the pipe section is made with specially designed PTFE seals.
The original version of the bubble-cap design was a single bubble-cap sized to provideoptimum vapour and liquid cross sectional areas. It has now been modified and adaptedto the tube diameters to ensure that the column sections are suitable for high vapourand liquid loading with small tray spacing and ensure a consistently high level ofefficiency over a wide operating range.
To achieve these benefits in their entirety, various designs of bubble-cap have beenselected. In the DN 80 and DN 100 nominal sizes kidney-shaped bubble-caps are usedand circular bubble-caps in DN 150.
Further information on column sections with bubble-caps such as areas of application,operating range, flooding point and pressure drop can be found in our special brochure"Column Sections with Random and Structured Packing and Internals”.
Bubble-cap internals and column sections can also be supplied on request inother materials.

MEASUREMENT & CONTROL
GeneralQVF measurement and control equipment complements the component range andensures that borosilicate glass 3.3 plant and apparatus operates safely. In addition tocommercially available equipment, which we always fall back on if it complies with ourcorrosion resistance requirements, we also offer a range of special items (in particulartransducers) developed either by ourselves or in cooperation with well-known companies.
Above all, because of their corrosion resistance, our transducers are widely used in thechemical and pharmaceutical industries and also in a wide range of related areas, aswell as food and drinks manufacturing, dyeing and the electroplating industry. Thespecial properties of borosilicate glass 3.3 and tantalum contribute to this plus the factthat borosilicate glass 3.3 is an approved and tried and tested material for theconstruction of pressure vessels.
The full range of standard equipment is described on the following pages. Reference ismade in the particular product description of special versions that can be supplied onrequest.
In addition to the individual items of equipment we can also supply completecontrol loops, measurement and control systems and process control systemsincluding the necessary documentation and control panels subject to therelevant regulations in each case (e.g. CENELEC).
GMP Compliant InstallationsThe use of transducers and, where required, the layout of interconnecting pipeworkincorporating valves when constructing plant and apparatus complying with GMPguidelines calls for special care in the design and selection of the components used andthe materials of construction employed for them. Because of its special properties thatare so highly valued in the pharmaceutical industry in conjunction with the PTFEmaterials (gaskets, special parts, bellows) approved in accordance with the FDA catalog,borosilicate glass 3.3 guarantees that the build-up of deposits is prevented in areas incontact with the product. The design and arrangement of many transducers results inthe avoidance of any dead space and ensures that they can be fully drained and easilyand effectively cleaned. Appropriate stainless steel coupling and support materials areavailable (please see section 9 "Couplings” and section 10 "Structures”) to ensure thatthe external design of these assemblies meets clean room requirements.
Permissible Operating ConditionsWhile the permissible operating temperature for all borosilicate glass 3.3 componentsis generally 200ºC, the permissible positive operating pressure is dependent on the mainnominal size and not on the shape of the component.
Detailed information on this can be found in section 1 "Technical Information”.

MEASUREMENT & CONTROL
The installation and operation of electrical equipment in hazardous areas is covered bythe "Regulations for electrical installations in potentially explosive atmospheres ElexV”.
EC Directive 94/9/EC (ATEX 100a)
This directive regulates the suitability of equipment and protective systems intended foruse in potentially explosive atmospheres and lays down fundamental safetyrequirements.
Fundamental Technical PrinciplesClassification of zones Hazardous areas are classified into zones based on the frequencyand duration of the occurrence of explosive atmospheres. Information and guidelineson the classification of zones can be found in IEC 60079-10 and national standards.
In Zones 0 and 1 only electrical equipment may be used for which a certificate ofconformity or a type examination certificate exists; in Zone 0, however, only apparatusspecifically certified for this purpose may be installed. The table below provides anoverview of the classification of zones and indicates the apparatus applicable to theparticular zone.
Dusts are classified in Zones 20, 21 and 22 and correspond to Categories 1D, 2D, 3D(D = Dusts).

MEASUREMENT & CONTROL
These are supplied as standard with safety flat buttress end and can be fitted in DN 25nominal size measuring branches. The measuring range is 0 to 200 ºC.
Thermometers for local display are made of 16 III Normalglas. They are mainly used inlaboratories and pilot plants and are available in three different versions. The angledversions are mainly used in column adaptors, spherical vessels and columns. Becauseof the properties of the mechanical sensors severe turbulence should be avoided in themeasuring vessel. The thermometers are filled with light oil (petroleum).
As these thermometers are made from 16 III Normalglas (equivalent to N16Bthermometer glass) it is not possible to make them in DN 40. It is, therefore,necessary to specify a spherical vessel with a DN 25 side branch when usinga THL45/... thermometer.
Our 45º and 90º angled thermometers have a scale that can be rotatedthrough 360° for ease of legibility.
Thermometers with limit contact can be found on page 8.7.

Wiring diagram
This comprises a DN 25 nominal size bypass tube, in which a glass float with a built-inmagnet moves up and down, and an externally fitted bistable max. and min. contactwhich is set or reset when the float passes it completely.
The standard scope of supply includes the borosilicate glass 3.3 float, two cast limitswitches (function: max. and min. closing with reference to the up and down travel ofthe float) with pipe supports and two PTFE float traps. These limit the movement of thefloat to the range being monitored. Further limit switches (see below) can be used forextra signalling of alarm situations. A DN 25 bypass tube of the length required shouldbe ordered separately.
The limit switches must be fitted with a contact protection relay or an isolatingswitching device with a II 2G EEx ia IIC T6 input.

Float Traps for Level ControlThe float traps listed here are used with type "LEC…” level controls. They are fitted aboveand below the magnetic float in one of the couplings used with the bypass tube. Theyhave a built-in bead on both sides for sealing purposes and, therefore, there is no needfor a separate gasket.
8.22
MEASUREMENT & CONTROL
This comprises a DN 50 nominal size bypass tube containing a glass float with built-inmagnet. An externally fitted level transmitter contains a chain of resistors with dedicatedreed contacts. The change of the resistance is converted by a flow converter in to a 4to 20 mA signal.
The standard scope of supply includes the measuring tube, the borosilicate glass 3.3float, the transmitter complete with fixings (pipe supports with support rings), two PTFEfloat traps and the connecting housing with built-in type II 2G EEx ia IIC T6 transmitter.The 4 to 20 mA output signal is available in a 2-wire version and must be supplied byan appropriate supply device. The measuring device can thus be operated in hazardousareas.
The float traps are built into the upper and lower measuring tube couplings and limit themovement of the float to the range to be measured. They have a built-in bead on bothsides for sealing purposes and, therefore, there is no need for a separate gasket.
Floats are available for two density ranges (see below). The depth of immersion in bothcases is between 50 and 90 %. The position of the resistor chain is arranged in relationto them in such a way that the magnet switches the first and last reed contact (0 to 100% of the level) at the maximum and minimum float position respectively. The contact gridselected as a function of the length of the measuring range (distance between thebypass tube connections) guarantees a good resolution. Further details can be foundin the table below.

ELECTRIC TIMERThis is an electronic timer used for controlling the reflux ratio in rectification columns withelectromagnetically or pneumatically operated reflux separators with magnetic controlvalves. The reflux and offtake times can be adjusted on the timer from 1 to 99 seconds.The boiling point is monitored with a resistance thermometer (Pt 100) and this intervenesin the control so that when a preset temperature is reached the timer switches to totalreflux or offtake and gives a warning that this has happened by sounding an alarm. Whena second cut-off value (hysteresis value from 1 to 9 seconds presettable) is reached, thecontrol returns to the preset timing cycle. There are 4 keys on the front panel which areused to enter all the preset values. Additionally there are 3 different programs available:
Program 0: all functions operating,Program 1: alarm off, fault warning offProgram 2: Pt100 off, output signal off, fault warning off

ELECTRODESFOR PH, REDOX AND CONDUCTIVITY MEASUREMENT
The TMXP controller is a pneumatic timer used for controlling pneumatic refluxseparators. As it operates completely pneumatically, it can be used without restrictionin hazardous areas. The reflux and offtake times can be adjusted on the timer from 0.3to 10 seconds or alternatively from 0.3 to 100 seconds. There are two buttons whichcan be used, when the timer is set to "Manual”, to switch it to total offtake or total reflux.When set to "Automatic” the timer starts the preset reflux ratio. Whether set to "Manual”or "Automatic” the instrument display panel indicates the current position of the refluxseparator (reflux or offtake).
The equipment available for process monitoring and control of pH, Redox andconductivity includes borosilicate glass electrode measuring chambers with PTFEflange. Up to two commercially available electrodes with PG 13.5 thread and 120 mmlong can be fitted in the PTFE flange. One screw thread is blanked off as standard. Themaximum operating temperature is 120 °C. The choice of a suitable electrode isgoverned by the process conditions.
If glass electrodes cannot be used for conductivity measurement, we can alsosupply inductive measuring cells for the measuring chamber.
Straight and angled dip tubes can be supplied in various lengths for use incolumns, receivers and spherical vessels.

IntroductionQVF couplings are a strong and high-duty system providing maximum reliability with theminimum of maintenance. This is achieved throughout the whole range of nominal sizesby the use of the safety buttress end, which has been designed specifically to take intoaccount the properties of the material, coupled with corrosion resistant, easy-to-installgaskets plus the carefully dimensioned individual parts of the actual coupling. Thematerials are selected to consider both the type of products being handled in the plantand equipment and also the possibility that they may be located in a corrosiveatmosphere.
The particular properties of borosilicate glass 3.3 and the fact that it is an approved andproven material of construction for pressure vessels are of prime importance in thisconnection. This is one of the reasons that borosilicate glass 3.3 is so widely used inthe chemical, pharmaceutical and allied industries together with other applications suchas food and drink production, dye works and electroplating.
The complete range of standard components available is described on the followingpages. Non-standard components can, however, also be supplied to special order.
A detailed listing of all couplings and individual components by »Description« and»Catalogue Reference« can be found in the »Index«.
Detailed information on couplings and a number of other topics referred to inthe following pages can be found in Section 1 »Technical Information«.
The use of flexible gaskets (please see page 9.24) makes it possible to achievea deviation of up to 3º and provides the same degree of movement as a balland socket system.
The term »DN« always refers in this section to the nominal size of the glasscomponents.
GMP and clean room compliant installationsThe design of plant and equipment complying with GMP regulations calls for special carein both the planning and selection of the components together with the materials ofconstruction used for them. Borosilicate glass 3.3 has a number of special propertiesthat are highly valued in the pharmaceutical industry, and these, in conjunction with PTFEmaterials (gaskets, bellows, lining) approved in accordance with the FDA catalogueensure that any build-up of unwanted deposits is avoided in areas which come in contactwith the product. A design without any dead space, which ensures that componentsdrain fully and can be cleaned easily and effectively, is achieved in the case of manycomponents by their shape and the way they are installed.
All these benefits can, however, only be taken advantage of if the gaskets used meetthe same criteria. For that reason we use exclusively gaskets made from PTFE of thehighest quality and can also supply a special GMP compliant gasket without any deadspace (please see page 9.23) in addition to the other types of gasket available.
Where the external surfaces of the pipeline have to comply with clean roomrequirements, appropriate stainless steel coupling and support material can be supplied(please see also Section 10 »Structures and Supports«).
We would be happy to advise you on the basis of the regulatory requirements applicableto a particular case and the guidelines drawn up by us for the design of GMP compliantplant and for plant suitable for use under clean room conditions.

Sealing In Accordance With TA LuftThe former German regulation "Technical Manual for Clean Air" (TA Luft) was amended,and the updated version came into force on 2004-07-24. It contains maximumpermissible limiting values for dust, steam, or gas emissions during the processing,conveying, or re-filling of dust, fluid, or gas materials.
TA Luft requires that flange connections conform to a specific leaking rate of10-5 kPa.l /(s.m). Compliance shall be proven by a design inspection in accordance withVDI 2440 (edition November 2000).
QVF flange connections have undergone design category inspections by TUEVRhineland / Berlin-Brandenburg, and fulfill the specified requirements.
The relevant certificates may be supplied upon demand.
Coated glass componentsDamage to borosilicate glass 3.3 components resulting from accidental external causescannot be entirely excluded, especially in the smaller nominal sizes. This isprimarily dueto the relatively rigorous conditions prevalent in production plants and applies especiallywhere no additional protection is provided in the form of insulation.
Standard couplings and inserts are used to install Sectrans coated borosilicate glass3.3 components.
In the case of components with a glass fibre reinforced polyester coating, which providesa higher level of protection, and can also be supplied on request, couplings completewith thinner inserts are required for nominal sizes DN 15 to DN 150.
Permissible operating conditionsAll couplings are suitable for operating temperatures of up to 200 ºC on the product side and for the permissible operating pressure applicable to the particular nominal size.Plastic flanges may, however, only be used up to an operating temperature of 150 ºCon the product side when lagged.
In the case of cover plate assemblies, quick release couplings and bellows,the operating conditions indicated in the respective product description apply.
Connection to other materialsThe requirement for connecting QVF borosilicate glass 3.3 plant and equipment to othermaterials of construction such as PTFE lined components, glass-lined branches andexotic materials, to mention but a few, is becoming more and more frequent
In addition to standard couplings for glass components, the following pages also containsolutions for these very different applications. They ensure that the normal bolting forcesapplicable to glass plant are applied but without being exceeded.

COUPLINGSComplete couplings include two flanges and two inserts in the selected materials andthe necessary quantity of stainless steel nuts, set screws, flat washers and springs. Adetailed description of all the individual parts can be found on pages 9.12 to 9.20.
Compression springs are used to set and maintain the correct bolt load on the coupling.Further information on this can be found under the Compression Springs heading onpage 9.20.
We recommend greasing stainless steel coupling set screws as protection againstseizure.
Couplings do not include gaskets which should be ordered separately andshould be selected in accordance with the operating requirements of eachparticular case (please see page 9.22 to 9.24).
Standard inserts can be used with Sectrans coated glass components (suffix»L«) but glass fibre reinforced polyester coated components (suffix »C«) in theDN 15 to DN 150 nominal size range require the use of thinner inserts (pleasesee section 1 »Technical information« and page 9.4).
In the DN 15 to DN 600 nominal size range fixed points are created by usinga combination of standard couplings and support frames (type A) or supportplates and support frames (type B) respectively in the structure. For nominalbore DN 450 use the special drilled flanges CCS450RRD or CSS450RRD. Inthe DN 800 and DN 1000 nominal size a special fixed point coupling (type C)is required. This includes a fixed point flange which is fixed directly to the heavyduty support stool.

There is a frequent requirement in process plant applications to open or close couplingsas quickly as possible without using tools. Charging materials to reaction or extractionvessels or replacing measurement indicators are typical examples of this. The idealsolution in such instances is our quick release couplings.
These comprise a stainless steel upper flange with slotted bolt holes, hinged quickrelease bolts and a lower plastic backing flange which is fixed to prevent it falling down.The support ring and the fastenings are stainless steel. As with all couplings, the gasketis not included and should be ordered separately.
QUICK RELEASE COUPLINGS
The permissible operating pressure for quick release couplings ranges from -1 to +0.5 bar g as the bolts can only be tightened by hand.
If thinner inserts are required for glass fibre reinforced polyester coated glasscomponents of nominal sizes DN 25 to DN 150 (please see page 9.4), thesuffix »C« should be added to the catalogue reference which then becomes»CVS..C«.
In nominal sizes DN 200 and DN 300 the standard couplings can also be usedwith Sectrans and glass fibre reinforced polyester coated glass components.

These shackle closures provide a more convenient solution for special applicationscompared to the quick release couplings described previously. They have a swivellingbracket and are closed or released by means of a spindle attached to it via a centrallylocated hand-wheel.
The flange, cover, bracket and hinged bolts are stainless steel. The cover is faced witha PTFE disc on the product side and the O-ring which is also corrosion resistant, islocated in a recessed groove so that it cannot fall out when the closure is opened.
SHACKLE CLOSURES
The permissible operating overpressure of the shackle closure is -1 to +0.1 bar. Theversion KMC...A may be deployed at an operating overpressure of +0.6 bar, if theunit is equipped with a local pressure gange.

Because of their low weight and relatively good corrosion resistance, glass fibrereinforced Duroplast backing flanges are used in the vast majority of installations. Theyprovide the additional benefit that they do not need earthing even if the products beinghandled are prone to setting up an electrostatic charge.
Flanges can be supplied in a variety of materials to complement the complete couplingsdescribed on pages 9.4 to 9.9.These are one-piece units up to and including DN 300nominal size and two-piece in the larger sizes. The materials used have been selectedon the basis of the bolting forces required whilst also taking into account the practicalrequirements of plant and pipeline in borosilicate glass 3.3.
The diameter and number of bolt holes as well as the PCD (QVF PCD) are identical forall types of the same nominal size. They can, therefore, be easily interchanged. However,the different set screw lengths required for DN 200 and DN 300 should be taken intoaccount.
Plastic backing flanges can be used up to a maximum operating temperatureon the product side of 200ºC. If the coupling is insulated, this temperatureshould not exceed 150ºC.

Because of the bolting forces required, only metal backing flanges are used for the largernominal sizes. The standard versions are made of spheroidal graphite cast iron (DN 450and DN 600) or profile steel (DN 800 and DN 1000).
These backing flanges consist of two halves joined together by means of locationsleeves and set screws. They are primed and then painted with epoxy resin to providethem with relatively good resistance to corrosion.
They are supplied complete with a bonded segmented rubber/glass fibre insert.
These backing flanges are made up of matching halves which carryappropriate identification. Non-matching halves should not be substitutedduring installation.

FIXED POINT FLANGES
In the DN 15 to DN 600 nominal size range, fixed points are created by using acombination of standard couplings with support flanges and vessel holders and supportrings with tubular support frames in the structure (please see section 10 »Structures &Supports«). In the DN 800 and DN 1000 nominal sizes, special couplings are used tomount fixed points directly onto a profile steel support frame. For this purpose a specialfixed point flange should be used as the lower flange. This is fixed directly to the U-profileframe by means of four support lugs set at 90°.
All fixed point flanges are supplied in epoxy resin painted steel or stainless steel. Theyconsist of two halves joined together by means of location sleeves and set screws.

Where borosilicate glass 3.3 components have to be connected to flanges onequipment in other materials of construction, different PCDs, bolt hole diameters andbolt configurations are generally involved. These adaptor flanges provide a solution tosuch problems. They have a larger than normal outside diameter and can be suppliedeither undrilled or drilled to a particular specification.
As the bolting force applicable to couplings for glass components is lower than for metalequipment, we supply adaptor flanges predrilled to your specifications but with bolt holediameters identical to those in our standard backing flanges. Where the mating flangeis drilled to take larger bolts, reducing washers (please see page 9.21) should be used.
Adaptor flanges can be supplied in cast iron (in the DN15 to DN150 nominal sizes) ormachined steel (in the DN200 and DN 300 nominal sizes) with an epoxy resin paintingor alternatively stainless steel.
If the flanges are required with a hole configuration differing from thoseindicated below, please provide details when ordering.

To achieve the required sealing load and to ensure that the coupling bolts aretightened evenly, first make the nuts finger-tight and then finish off with aspanner (from DN 80 upwards alternating between bolts on opposite sides ofthe coupling). The free length L0 and compressed length L1 are shown in thetable below.
In addition, with couplings in the DN 450 to DN 1000 range the compressedlength L1 should be checked after the plant is heated for the first time and ifnecessary the set screws retightened.

The diameter of the bolt holes in these flanges is identical to theequivalent type of standard flange described on pages 9.12 and 9.14 in order to limitthe bolting force to the figure applicable to glass components.
As the mating flange is usually drilled to take larger bolts, reducing washers should beused to locate the smaller bolts centrally in the mating flange hole. These are suppliedin stainless steel as standard.

‘O’ ring gaskets are made to the highest standards from pure, high quality PTFE.
‘O’ ring gaskets are also suitable in many cases for connections tocomponents in other materials of construction provided the surface does notexhibit any great unevenness. We would be happy to advise you in cases ofdoubt.

If borosilicate glass 3.3 components have to be connected to PTFE-lined components,we recommend the use of a flat gasket in addition to the ‘O’ ring gasket. The standardbolting forces applicable to the connection of glass components are then adequate forthese applications and the ‘O’ ring cannot press into the PTFE sealing surface. Theseflat gaskets are also made from a PTFE material of selected quality.
The essential difference between this special type and the version described on page9.22 is that the seal between the glass components is made on the internal bore. To dothis it was necessary to replace the ‘O’ ring with a flat, slender sealing bead. The samequality material is used as for the »TR..« type.
In addition, these gaskets have a double collar that prevents the product escapingradially in the event of leakage.

BELLOWS
Permissible operating conditions for »FB..« bellows
Permissible operating conditions for »VB..«, bellows
Bellows are important elements in the construction of borosilicate glass 3.3 plant andpipeline. They can be used not only to compensate for expansion and contraction dueto changes in temperature but also to avoid stress within plant or to ensure stress-freeconnection to other components, usually in other materials, which could induce vibration(e.g. service lines, pumps, stirred vessels, etc.). The versions described below take intoaccount these various applications.
Bellow flanges are supplied in either epoxy resin coated, spheroidal graphite, cast ironor stainless steel. Screws, nuts and compression springs are stainless steel in bothversions.
The relationship between permissible operating pressure and temperature forthe various types of bellows is indicated in the tables below. If used at themaximum permissible operating temperature of 200 ºC, they are only suitablefor use without any internal pressure. Intermediate figures can be interpolated.
As this table indicates, »FB..« type bellows of DN 80 and above cannot beused under vacuum at temperatures in excess of 100 ºC. In such cases type»VB..« vacuum bellows, which have an internal stiffening tube, should be used.
The bellows are set to the correct length with the permitted amount ofmovement ±DL (please see table) using locknuts before leaving the factory.The adjustment of the locknuts at the time of installation and the support andrestraint of equipment should be such that the forces resulting from pressureor vacuum in bellows does not result in undue stresses in the pipework. Forfurther information please consult our sales engineers.
We can also supply bellows for higher operating pressures as well asdissipative PTFE bellows.

STRUCTURES & SUPPORTS
GeneralQVF structures are designed to support plant and other equipment comprisingcomponents exclusively or principally in borosilicate glass 3.3. Because of the specialrequirements resulting from the use of this material, structures are now available in theform of a proven modular system that not only meets standard requirements but alsoprovides or facilitates solutions for problems of a very special nature.
Basically these structures consist of steel tubing in three different diameters which isconnected using the appropriate fittings. As a result, the structures can not only bedismantled and reassembled whenever required but they can also be modified andadded to quite easily. The modular system also includes components for establishingfixed points, supporting spherical and cylindrical vessels and horizontal cylindricalcomponents plus a wide range of supports, to mention just the most important items.The result is an extremely flexible system.
The full range of components, which are available as standard in galvanised mild steeland to some extent in stainless steel, is described in this section. Special versions, whichare available on request, are referred to under the respective product descriptions.
A detailed listing of all structure components by »Description« and »CatalogueReference« can be found in the »Index«.
If any supports are required which you cannot find in this section, please contact us.Space does not permit the inclusion of every possible version in this catalogue.
Design of tubular structuresThe diameter of structure tubing to be used plus minimum dimensions, i.e. width anddepth of tubular structures are determined by the nominal size (cylindrical glasscomponents) or diameter (spherical vessels) and the weight of the components they aredesigned to support. Details can be found in the table below and the related illustration.If additional equipment or complicated pipework needs to be accommodated in astructure, appropriately larger sizes should be used.
The sizes of structure tubing and other fittings indicated for the various nominalsizes, shapes and configurations of glass components should be adhered to.If this is not possible due to special circumstances, please seek our advice onthis and any other problems relating to structures.
The figures for DN 800 and DN 1000 cylindrical components and 500 litrenominal capacity spherical vessels only apply to installations with a low totalweight. In all other cases, we recommend the use of a heavy duty fabricatedbase structure.

STRUCTURES & SUPPORTS
The establishment of fixed points is of particular importance. They are formed bycombining a light duty support frame or heavy duty support frame with a coupling, asupport plate or a support element (vessel holder, angle bracket, etc.). Fixed points haveto carry the entire weight of a unit or column and should therefore, be located at thelowest point (in the case of a vessel holder) or lowest possible point (in the case of asupport plate) in the installation.
If there is the risk of vibration generated in the vicinity of glass units being transferred tothe tubular structure, appropriate preventive measures should be taken.
The structure components described on pages 10.5 to 10.8 can also be used tosupport platforms and walkways for the use of plant operators and maintenance staff.They are connected directly to the plant support structure which results in a particularlycompact design. The decking of these platforms and walkways is in the form of gridsor embossed metal sheets.
Where supports are used in a structure for individual components or assemblies, theseshould be installed in such a way that the glass components are subject in the main tocompressive forces. It has to be taken into consideration, that normally an additionalfixed point is created at such points.
Support structures must be sufficiently rigid to prevent any bending of the individualtubes in excess of the permissible amount and the subsequent transfer of external stressto the glass components. This is achieved by incorporating additional bracing
Glass components must be able to expand freely from a fixed point, thereforea bellows is generally fitted between two fixed points.
For rigidity at least two adjacent sides of the structure should be provided withdiagonal bracing. In addition, tall structures (e.g. for columns) should bebraced back to existing structural steelwork or the walls of the building.
Assembly of the glass components must always be started from the fixedpoint.
Glass units and their structures expand at different rates as a result of changein temperature. The unit must, therefore, be able to expand above the fixedpoint without restraint.
Guides giving lateral support must always be provided for units and columns.
If the overall height of the unit or column is fairly low this can be achieved byusing two »KK50-5« or »KK50-7« structure fittings each with one of the setscrews of a horizontally positioned coupling passing through them.
Above a certain height this is achieved with a light duty support frame whichcan also be used to support the weight of glass components during installationand maintenance work.
Guide elements should not be bolted rigidly to the unit or plant duringoperation.
10.4
STRUCTURES & SUPPORTS
Supporting Horizontal PipelineBoth horizontal and vertical pipelines must be supported at certain intervals to avoidsubjecting them to additional stress due to bending or lateral movement (e.g. on eitherside of bellows). The recommended spacing of horizontal pipeline supports as afunction of nominal size is indicated in the table below.
Clean Room DesignStainless steel structure, support and coupling components can be supplied for usein applications where clean room conditions apply (see also Section 9 »Couplings«).
We would be happy to advise you on the requirements applicable in each particularcase using the guidelines we have drawn up for the design of complete tubularstructures for use under clean room conditions.

STRUCTURE TUBINGThis tubing is used in conjunction with the structure fittings described on pages 10.6 to10.8 to form the basis of structures to support borosilicate glass 3.3. plant. Structuretubing is available in three sizes and can be supplied in galvanised mild steel or stainlesssteel. This is to take into account the fact that glass is used in areas where variousdegrees of corrosive atmosphere are encountered.
As it is important that the structure tubing should not bow by more than 2 mm, themaximum permissible free length of the tubing is dependent on the load it is carrying.This can be calculated, at a fixed point for example, as the sum of the weights of supportframes, glass components including couplings and liquid content. The number ofsupport points should also be taken into account. Further information can be found inthe illustration alongside and the diagram below.
The structure components described below and on pages 10.6 to 10.8 can also be usedto support platforms for the use of plant operators and maintenance staff. They areconnected direct to the plant support structure which results in a particularly compactdesign. The decking of these platforms is in the form of grids or embossed metal sheets.
Permissible structure tubing load as a function of unsupported length
If individual lengths of tubing are required cut to a specific length, please addthe length (in mm) to the catalogue reference.
For tubular structures that are to be installed in clean rooms, we can alsosupply stainless steel tubes with a ground finish on request. The cataloguereference is then for example: »M-RO7E/..«.

STRUCTURE FITTINGSClosed sided fittings are used principally in conjunction with structure tubing to buildcomplete structures where the design has been fixed prior to installation together withthe necessary support frames, brackets, diagonal bracing and supports. In such casessubsequent modifications can only be carried out on a restricted basis.
If it is expected at the time of the original installation that extensive modification may berequired or will have to be carried out subsequently, we recommend that the use of opensided structure fittings be considered. They are also ideal for items added to thestructure at a later stage ( e.g. support frames) or extra fittings (e.g. brackets).
We can supply a comprehensive range of closed and open sided structure fittings tocater for the various applications and the many different requirements encountered inpractice. The finishes available are galvanised (catalogue reference »KK..« and »KKO..«),coated blue (catalogue reference »M-KK..« and »M-KKO..«) and to some extent stainlesssteel (catalogue reference »KK.. E« and »KKO..E«). Further details, including details ofthe various possible uses of the individual fittings and the necessary accessories, canbe found in the tables on pages 10.7 and 10.8.
The structure components described on pages 10.5 to 10.8 can also be used tosupport platforms for the use of plant operators and maintenance staff. They areconnected directly to the plant support structure which results in a particularly compactdesign. The decking of these platforms is in the form of grids or embossed metal sheets.
If type »KKO..« structure fittings are fixed to horizontal tubes, they shouldalways be located on top of the tube, so that a closed assembly is ensured.

STRUCTURES & SUPPORTS
One of the best ways to fix supports in structures is to use screwed rod. This isconnected directly to the tubular structure using structure fittings or, where heavycomponents are involved, using structure bushes as well. In addition, structure bushesare also required to fix support brackets and support saddles (see pages 10.14 and10.15) in the structure.
In special cases, it is also possible to fix vessel holders and support rings (see pages10.13 and 10.14) and column support plates (see page 10.12) directly to the tubularstructure using structure bushes. There is then no need to use a support frame (seepage 10.11).
REDUCING FITTINGSIf it is necessary for design or technical reasons to reduce the diameter of the tubingused in a support structure, the reducing fittings listed below can be used. In principle,these should be handled in the same way as »KK14.. « sleeve couplings.

SUPPORT STOOLS
Because of the considerably greater weight to be supported when tall units and columnsin the DN 800 and DN 1000 nominal sizes are involved, the design of the fixed pointmust be more substantial than in the smaller nominal sizes. The ideal solution is a heavyduty support stool which can be combined with a fixed point flange (see section 9»Couplings«) and on which the 60mm tubular structure required is erected. A typicalapplication is shown in the illustration alongside.
Plant and columns must be able to expand without restriction from a fixedpoint, therefore a bellows is generally fitted between two fixed points.
We can also supply suitable designs for special sizes and other nominal sizeson request.

SUPPORT FRAMESThese frames are used in the DN80 to DN600 range of nominal sizes as a base elementfor a fixed point and are installed horizontally using tubes and fittings on a framework inthe structure. Cylindrical components are then fixed directly via a coupling (see pages9.4 to 9.10) or indirectly via support plates (see page 10.12). Spherical and cylindricalvessels are supported indirectly via vessel holders or support rings (see pages 10.13and 10.14 ). These elements are connected to the support frames using screwed rodwhich, for stability reasons, should be as short as possible. They are also used to alignthe couplings or structure elements supported on the support frames.
Support frames are supplied in galvanised finish or stainless steel and have a QVF PCD.The material required for fixing the support frames and the screwed rod required (seeabove) are included in the supply.
Information about using these support frames with couplings, vessel holders, etc. canbe found in the respective product description.
Plant and columns must be able to expand without restriction from a fixedpoint, therefore a bellows is generally fitted between two fixed points.
Plant and columns must always be provided with lateral support. Above acertain height, support frames should be used for this purpose.

STRUCTURES & SUPPORTS
SUPPORT PLATESIndirectly installing cylindrical borosilicate glass 3.3 components on support framesusing support plates offers a significant benefit compared to the combination of acoupling and light duty support frame: the glass components above and below can beinstalled and dismantled independently from each other. As the PCD is different, thesupport flange remains firmly connected to the support frame or structure during suchwork.
Another benefit of the support plate is that the weight of the glass componentssupported on it only results in compressive stress therefore as a rule there is no needto compensate for this weight.
Support plates consist of a steel ring, which is primed and protected against corrosionby an epoxy resin paint, and a high grade PTFE sheath. The complete assembly alsoincludes the coupling components for the glass such as bolts, nuts, washers, andcompression springs but no flanges. As the support plate incorporates a sealing beadon both sides, no additional PTFE gaskets are required.
The support plate metal rings can also be supplied in stainless steel on request.

SPHERICAL VESSEL SUPPORT RINGS
ANGLED SUPPORT BRACKETS
This type of ring can be used to support borosilicate glass 3.3 spherical vessels up toa nominal capacity of 20 litres. They are stainless steel and are fitted with a close fittingsilicon rubber sleeve. All support rings are drilled to a QVF PCD.
An alternative method of supporting these small spherical vessels in a tubular structureis by means of support brackets (see page 10.15). These are connected to the couplingon the top neck and this then forms the fixed point.
These brackets are used to support horizontal assemblies in the DN150 to DN300nominal size range such as horizontal separators (see section 4 »Vessels & Stirrers«) orshell and tube heat exchangers (see section 5 »Heat Exchangers«). They are fitted to acoupling using longer set screws or fixed by means of »RRM..« structure bushes andclosed or open structure fittings (see pages 10.6 to 10.9) to cross members.
Angled support brackets are supplied with either a galvanised finish or stainless steelas standard. The material required for connection to the tubular structure (see above)should be ordered separately.

PIPELINE SUPPORT BRACKETSThese brackets are used in tubular support structures in conjunction with open sidedstructure fittings (see page 10.8), which guarantee the flexibility required in installation,and short lengths of structure tubing to provide a versatile support for borosilicate glass3.3. components. They are supplied in a galvanised finish as standard.
As these brackets have the same PCD as the corresponding flange, they can beconnected directly to a coupling. However, the standard set screws should be replacedby longer set screws or screwed rod which is available in all the normal diameters. Bothshould be at least 50 mm longer than the standard set screws to ensure an adequatesetting range.
Fixing pipeline support brackets couplings nearly always creates a fixed point,from which glass components must be able to expand without restriction,therefore a bellows is generally fitted between two fixed points.
If long horizontal tubes are required to connect pipeline support brackets tothe structure, these must be braced diagonally.
SUPPORT SADDLESThese support saddles with bracing strap are designed to support DN450 and DN600assemblies such as horizontal separators (see Section 4 »Vessels & Stirrers«) in tubular structures. The lower part consists of a steel bar with segmented rubber liningand a profiled steel support frame. It is fixed by means of »RRM.« structure bushes andclosed or open structure fittings (see pages10.6 to 10.9) to horizontal structure tubes.The upper part is a rubber lined metal strap braced to the lower part by means of captivescrewed rods and nuts.
Support saddles are supplied with either a galvanised finish or stainless steel asstandard. The material required for connection to the tubular structure (see above)should be ordered separately.

PIPELINE SUPPORTSThese supports are used in conjunction with open sided structure fittings (please seepage 10.8) which guarantee the flexibility required in installation, or structure feet andshort lengths of structure tubing to support borosilicate glass 3.3 pipeline componentsin tubular structures and from walls. They consist of a two-piece rubber collar whichgrips the glass pipe firmly and a ‘U’ bolt fixed to a backplate. The latter has a socket sothat it can be connected to the structure.
Pipeline supports are supplied with metal parts either in galvanised finish or stainlesssteel as standard. When correctly installed they do not constitute a fixed point, i.e. theweight of vertical pipelines should be taken up by other means, e.g. using pipelinesupport brackets.
When these supports are used for horizontal pipelines the recommended spacingindicated on page 10.4 must be adhered to. In the case of vertical pipeline, the distancebetween two supports should not exceed 5 meters.

SAFETY SCREENSFitting support structures with safety screens meets two safety requirements at the sametime: operating personnel are protected from any hazards that may arise from possiblebreakages and the units are protected against mechanical damage arising from externalsources.
Safety screens consist of sheets of medium flexibility transparent PVC with highresistance to abrasion. To ensure good lateral stability, they have galvanised metal stripsbolted on both sides at the top and bottom. Hooks are also fitted to the top edge toenable the safety screen to be suspended from the structure.
Safety screens are 5 mm thick. Up to a width of 1100 mm they are supplied in one pieceas standard. Larger screens are two-piece with an overlap. The maximum possiblelength is 6 metres.
Safety screens can also be supplied on request in special widths, in articulated form or,where the complete structure requires screening, with sliding panels or with coveredhand holes on the operating side.
When ordering, the required height in mm should be added to the cataloguereference.
We can also supply rigid PVC safety screens with antistatic coating, i.e.electrically conductive surface, on request. These are suitable for use in areaswhere electrostatic loading is possible. The surface resistance is 106 to 107Ω.
