The LISEGA product program embraces all elements
that are required to create the latest, state of the art
pipe support concepts.
These components correspond to the LISEGA standardization
philosophy and are organized in a modular system
with load and attachment compatibility.
Containing the complete product program, this catalog is in full
compliance with LICAD (Rev. 8), the LISEGA pipe support design program.
The catalog is available, identical in all details, as a pdf-file:
either as a CD-Rom or directly from our homepage.

STANDARD SUPPORTS 2010
LISEGA is differentAs far as the mutual success of customers and suppliers is concerned, one can’tdo without the other! Accordingly we act as partners for our clients and under-take every effort to make them aware of that. We know this can only be reachedby optimum performance. Not only that - we have to be the best. This way, wecan convince customers or perhaps even rouse their enthusiasm - and we areonly satisfied when that’s achieved!
The constant challenge excites us, for we love suc-cess. There is no greater motivation than success.In order to be the best, we have specialized. Our whole concentration is centered on pipe supports, and has been for more than 35 years.
Regarding our particular sphere, we have a com-prehensive understanding of it. Not only qualityand price determine the customer benefits of theproduct; low application costs are equally import-ant. Often, these alone can prove decisive for thesuccess or failure of a project.
Customer benefit demands the highest efficiencyfrom us. This is why performance with system hasbecome the foundation of the organization and anessential factor in our strategy. On this keynotewe also support product application: standardi-zation, the modular system, series production and user software (LICAD) are themost important elements to this end. Just for this, our customers have made usinternational leaders!
With the catalog in hand, Standard Supports 2010, we wish to present our latesttechnology, and via comprehensive and clearly structured information, make a further contribution to efficient product application.
This is quite in the spirit of our objectives - superior product quality at the keen-est costs for the customer! Even if these aims do seemingly compete, we stickto them, because this is the most effective way to recommend ourselves as partners - and above all, we have already proved it.
That’s why LISEGA is different… through performance with system!

1. STANDARD SUPPORTS
1.1 RequirementsFor the support of industrial piping systems,the use of standard supports is regarded aswell proven, up-to-date technology.
Only a correspondingly high level of standar-dization in support components can adequatelysatisfy the justifiable demand for productsthat are technically top-class and economi-cally attractive at the same time. The complexrequirements for modern pipe supports are:
➜ reliable functioning➜ maintenance-free operation➜ low unit prices➜ simple planning with DP systems➜ instant availability➜ economical installation strategy➜ easy to install designs➜ supplementary service benefits
1.2 DefinitionStandard supports must fulfill the followingcriteria:
➜ component shapes are uniform and designed for optimum exploitation of material
➜ units are compatible regarding connectingdimensions and loading capacity
➜ units are cataloged and clearly identifiableby a designation system
➜ components are manufactured in series production
➜ components comply with the relevant standards and international regulations
➜ functional capacity, suitability and durability of the units is well proven
➜ components are certified and approved for use
The relevant codes for pipe supports inGerman plant construction (power plants),VGB guideline R 510 L, require the preferen-tial use of standard supports and define thecriteria as follows:
“Standard supports are pipe support com-ponents, the construction of which, in formand dimensions as well as in the designdata relating to loading capacity, is certificatedand cataloged, and which are manufacturedaccording to firmly established, reproducibleprocedures, e.g. series production”.
2. LISEGA STANDARD SUPPORTS
2.1 ScopeAt LISEGA, standard supports form the basisof a comprehensive performance package. A complete program from more than 8000standardized components thereby covers alloperational loads, temperatures and travelranges normally met in piping systems inindustrial plant construction:
➜ � 1200°F operating temperature for pipe clamps and clamp bases
➜ 90 kips nominal load for all mainly statically determined components
➜ 224 kips nominal load for rigid struts and standard shock absorbers
➜ 1124 kips design load for large bore shock absorbers
➜ 36 inch travel range for constant hangers
➜ 16 inch travel range for spring hangers
2.2 Design featuresSpecially developed components are availablefor the various support functions. In thedesign and construction of the units, funda-mental design principles have been takeninto consideration:
➜ symmetrical design shapes➜ compact installation dimensions➜ especially reliable function principles➜ extra wide adjustment ranges➜ fully compatible load ranges and
connection dimensions➜ favorable performance/weight ratios➜ integrated installation aids
TECHNICAL SPECIFICATIONS
The products outlined inthis catalog - STANDARDSUPPORTS 2010 - are fullyin line with the latest deve-lopments in support tech-nology and satisfy generalrequirements for plantinstallation at the highestlevel. For the generaldesign of LISEGA standardsupports, uniform criteriaare applied. They aredescribed in the followingTECHNICAL SPECIFICATIONSand are binding for thecontents of this catalog.Componentrelated featuresare outlined in the corre-sponding sections of theproduct groups and in thetype data sheets
Unless expressly agreedotherwise, the stipulationsin the catalog STANDARDSUPPORTS 2010 apply toall our shipments.

0The LISEGA modular system is specially targ-eted towards this efficiency. The standardi-zation of components forms the foundation andis the precondition for rational series produc-tion, dependable quality, systematic warehou-sing and computer assisted application. Withthe LICAD design system and correspondinglogistics, significant rationalization effectscan be achieved in engineering, design andinstallation.
3.2 ScopeThe standardization at LISEGA extends bey-ond the components to their systematic inte-raction. To this end, load and travel distri-bution as well as function and connectionsare meaningfully coordinated.
In this way the LISEGA standard supportprogram has been developed as a functionalmodular system with logical linking. The indi-vidual units form modules therein and arecompatible regarding loads and connections.This enables the formation of meaningful com-binations to produce support configurationsfulfilling all requirements. The large selectionof components makes adaptation possible towidely differing support and applicationsituations.
3.3 Product groupsThe standardized units are divided into 7product groups according to their basic modesof function (see diagram, page 0.3, and table,Standardized Components, page 0.4).
3.4 Load groupsTo guarantee compatible loads in unit com-binations, the load spectrum is split intofixed load groups.Within a load group (nominal load), all com-ponents feature uniform load limits and stresssafety characteristics. The connection shapesof the units (threads - either metric or UNCaccording to market area - or pin diameters)are uniform within a group and thus compat-ible. Components of different product groupscan therefore be connected only within a uni-form load group to safe load chains and thefaulty combination of different load groupsis precluded. As all units in a load group aredesigned uniformly regarding strength, thestresses on a complete chain of components
In addition, LISEGA hangers feature only oneupper attachment point. As a result, and duealso to the compact and symmetrical designshape, the load transfer free of moments tothe connecting elements is ensured andsimple installation enabled. The operationalposition of the moving parts (hangers, supports and shock absorbers) can be readdirectly off a travel scale. Load adjustmentof the constant hangers and supports can bemodified at all times, also in the installedcondition under load. Hangers and supportscan be blocked in any travel position.
2.3 Principle of the optimum design typeFor the design of support components, opti-mum coverage of the specific support func-tion is the decisive factor. For each functiononly one component is therefore required,namely, the optimum one for the purpose.The project engineer is spared costly selectionfrom a series of alternative solutions. Thisnot only facilitates application but alsoincreases safety. Above and beyond this, itis a prerequisite for the rational applicationof standardized construction on the principleof the modular system.
➜ There’s only ONE best solution!
3. LISEGA MODULAR SYSTEM
3.1 FundamentalsThe cost of pipe supports is a major elementin the total cost of a piping system. The cost of the supports is the accumulatedtotal cost arising from:
➜ project management (processing)➜ design and engineering work➜ use of materials (components) as well as➜ installation work
The pipe supports are almost always criticalfor the commissioning deadline and can,through delayed delivery, cause incalculableextra costs. The aim of LISEGA product stra-tegy is to forge, out of all the cost factors in-volved, the common cost minimum for theuser in the sense of the economic principle.
The economic principle:

groups and load cases, are set out in theLISEGA load tables (see page 0.5). The defini-tion of load cases is regulated according toASME III, Div. 1 Subsection NF, ASME B31.1/MSS SP58 and DIN 18800, VGB-R 510L, KTA 3205.The load table applies uniformly to all com-ponents in the LISEGA modular system andto other LISEGA units systematically connectedto it, e.g. integral special designs (see loadtable, page 0.5).

are uniformly determined.For permissible stresses, a difference is madebetween statically and dynamically determinedcomponents. The units in product groups 1,2, 4, 5, 6 and 7 are stressed in only oneload direction (statically or quasistatically)and are considered to be statically determinedcomponents. The components in ProductGroup 3, as well as their accessories, areloaded in alternating directions and are there-fore regarded as dynamically determinedcomponents.

Standardized components
3.5.1 Static componentsThe nominal load is used for the determin-ation of load groups. For the statically deter-mined components in Product Groups 1, 2,4, 6, 7, the nominal load corresponds to the max. adjustment load of the spring ele-ments, such as spring hangers and constanthangers. The maximum permissible hot load(load case H) lies considerably higher thanthe nominal load when components areused as rigid supports, and is tied to theload capacity of the connection threads.LISEGA threaded rods should therefore onlybe replaced in kind (see page 6.5, 6.6).
Spring and constant hangers in the blockedposition also count as rigid supports, where-by for cold loads in hydrostatic tests (shortduration) the emergency loads (level C) canbe exploited.
For Product Group 4 (pipe connections) a lim-ited area of overlapping in the load groupsis foreseen, due to the temperature-related,variable spectrum of loading capacities. Dataon the permissible loads relating to the res-pective operating temperature are set out forpipe connection components in the indivi-dual type data sheets.
For Product Group 5 see 3.5.5, page 0.5.
3.5.2 Dynamic componentsFor dynamically determinedunits, the stipulation of thenominal loads follows fromthe meaningful division ofthe standardizable loadspectrum. Here, the nominalload corresponds at thesame time to the operatingload for load event levelA/B (ASME).As these components aregenerally used to guard against emergencies, theload event level C (ASME),possibly even level D, isusually adopted as the max.expected operating load. In each case the projectengineer’s instructionsapply.

3.5.5 Product Group 5The units in Product Group 5, pipe clampbases for cold piping systems, cryogenicsystems, as well as roller bearings and pipesaddles, are regarded as statically determined,but are not directly connected with the hangersupports. As they are comparable with secon-dary steel components, they constitute a spe-cial group. The nominal load correspondshere to the max. operational load accordingto level A.
� Max. operating load for spring and constant hangers correspon-ding to max. load on load springs.
� Permissible loads according to the design criteria for US code MSS SP 58 (ASME B 31.1).
� All loads are to be included hereunder that can possibly resultfrom the normal operation of theplant, including start-up and shut-down, load tolerances and hydro-static tests.
� Loads outside normal operation are grouped hereunder, possibly also hydrostatic tests. In each case a final inspection of the whole support arrangement is recom-mended.
� For the given loads, the yield stress of components can be reached. In each case replacement is recommended.
� Hereunder all dynamic loadsare to be included that can pos-sibly result from plant operation,including pressure shock forcesfrom valve operation, and perhapsoperating basis earthquakes (OBE).
� Hereunder all the dynamicloads are grouped which lie out-side normal operation, as for example safe shutdown earthquakes(SSE). In each case a final inspec-tion of the whole support arrange-ment is recommended.
� Dynamic loads from faultedconditions. For the given loads,the yield stress of componentscan be reached. Replacement isrecommended in each case.
� Load groups 1 and 2 are loadand connection compatible, where-by load group 1 applies to thesmallest shock absorber and loadgroup 2 to the correspondingrigid struts and weld-on brackets.

3.6.1 Travel ranges of static componentsMoving parts such as spring and constanthangers are divided into travel ranges corres-ponding to the usable spring travel of thestandard springs employed.The appropriate travel range in each case ismarked by the 4th digit of the type desig-nation according to the following table.
For spring hangers and supports (ProductGroup 2) the springs are already installedpreset to approx. 1/3 of their nominal load. The initial load follows from this and thespring travel is correspondingly reduced.
3.6.2 Shock absorber travel rangesThe maximum strokes of LISEGA shock ab-sorbers are divided into economical strokeranges as standard, and are so designatedin the 4th digit of the type designation ac-cording to the following table.
3.7 Type designation
All components can be clearly identified viacoded type designations. Six digits containall the necessary information required. The type designation system facilitates theuse of modern information technology andenables the unrestricted application of themodular system in current CAD programs.

5. MATERIALSMaterials are exclusively used which corres-pond to ASTM material requirements andDIN or DIN-EN norms.
As a matter of principle, only materials ofguaranteed strength properties are used forsupporting components.
6. QUALIFICATION LEVELS FOR STANDARD ANDNUCLEAR APPLICATIONStandard supports have the same functionboth in the conventional and in the nuclearfield of application, and therefore do not
differ in design. Due to additional quality-assuring measures and materials with spe-cial certification, separate manufacture is how-ever necessary.
4. STANDARDS AND CALCULATIONSIn design, stress and load calculations, aswell as in manufacturing, the relevant Germanand international standards, technical regu-lations and codes are taken into account.
The characteristic values of materials that alldesign calculations are based on are takenfrom the relevant standards and recognizedtechnical codes.
Worldwide coverage of recognized codes and standards!
Standardized selection of high temperature materials!

5.1 Preferred materials for pipe connection parts
0.10
0In the field of nuclear application, all mate-rials are traceable right through to the finishedproduct via heat number restamping, and thecomponents themselves are marked accor-ding to ASME and KTA regulations. In thetype designation, the nuclear design is notedin the 5th digit (for struts, the 6th digit). Therelevant component documentation relatesto this and to the fabrication order number.
In this catalog, the standard design, i.e. non-nuclear applications, provides the basis forthe type designations. As the given function-al data and unit dimensions are the same fornuclear applications, selection can also bemade here with the help of the catalog. On planning or ordering, attention must how-ever be paid to corresponding conformity ofthe type designations. The table showing thetype designation system (3.8, page 0.7) can beconsulted in this respect.
7. WELDINGAll welding is carried out as gas metal arcwelding - in special cases by stick welding.LISEGA holds certifications according to:
➜ ASME III Div I NCA NPT stamp➜ DIN EN 729-2 by the German TÜV➜ AD-HPO, production and testing of
pressure vessels, by the TÜV➜ DIN 18800 T7 Extended suitability
certification for steelwork and bridge construction by the SLV, the training and testing institute for welding technology
LISEGA welding inspection personnel are qua-lified according to ASME III NCA 4000 NF,DIN EN 719, AD HP3 and HP4. Non-destructive tests are carried out by testingstaff qualified acc. to ASME IX and DIN EN473, level 2, and SNT-TC-1A, level II.
Supporting connections are produced corres-ponding to the material group by qualifiedwelders according to ASME IX or DIN EN287, part 1. The welding procedure is quali-fied according to ASME IX and DIN EN 288.
8. SURFACE TREATMENT
8.1 Standard coating systemsThe surfaces of LISEGA products are protectedas standard from corrosive influences by highquality protection systems that are also sui-table for external use in aggressive conditions(coastal, industrial and chemical areas). The following coating systems are applied to the different products:
8.1.1 Primer coatingComponents that are either to be welded to existing structure in the plant or simplyrequire higher quality transport protection arecoated on a bright metal surface with wel-dable primer (thickness app. 1.18 mil [30µm],color reddish brown).
8.1.2 ElectrogalvanizingSpring hangers and supports up to load size9, as well as all threaded parts and specialfunction parts, are electrogalvanized (zincthickness app. 0.59 mil [15µm], yellow chro-matized).UNC threaded parts are white chromatized.
8.1.3 Paint coatingsConstant hangers and supports and otherproducts according to table 8.2 receive thefollowing surface treatment:
1. Steel grit blasting according to SP-6 orSP-10 for the U.S. and EN ISO 12944-4grade SA 2 1/2 for Europe.
2. Undercoat of 1-component polyurethanezinc dust primer, dry film thickness 2.36 mil[60µm], approx. 62% zinc in solid statevolume, color grey.
3. Final coating of 2-component acrylic poly-urethane paint, dry film thickness 2.36 mil[60µm], color RAL 5012, light blue.
The total dry film thickness of the systemamounts to approx. 4.72 mil [120µm].
8.1.4 Hot dip galvanizationRoller bearings, pipe saddles and cryogenicpipe clamp bases are hot dip galvanized asstandard, zinc thickness approx. 2.36 mil[60µm].

8.2 Standard surface protection in order of products (corresp. to 8.1)
8.3 Extended surface protectionFor applications in the open involving highlycorrosive conditions, such as coastal sites orchemical plants, extra protection can be sup-plied, insofar as this has not already beenprovided as standard by hot dip galvanizingor special steel versions. The following coa-ting systems are thereby applied:
8.3.1 Electrogalvanization with additionalcoats of paint1. A barrier layer (dry film thickness 18 mil[30µm]) is applied to the galvanized surfaceacc. to 8.1.2.
2. As a final layer, a 2-component acrylicpolyurethane finish (dry film thickness 2.36mil [60µm], color RAL 5012 - light blue) isapplied.
8.1.5 Stainless steel designsShock absorbers and energy absorbers (E-Bars) are made entirely of non-corrodingmaterials. Connecting parts are electrogal-vanized according to 8.1.2.
8.1.6 Cathodic immersion process (CIP)All LISEGA springs are given special treat-ment because of their distinctive functional
significance. The peeled surface of the springsis steel ball blasted and zinc-phosphated; sub-sequently a 2-component epoxy resin coatingis applied via electroimmersion and thenburnt in at approx. 392°F [200°C] (CIP). This highly sophisticated process has beenadopted from the automobile industry.

9. CONNECTION DIMENSIONS
9.1 Installation dimension EFor the simple determination of minimuminstallation lengths, the installation dimen-sion E is given for all components except theconnecting rods (Product Group 6). Thisdimension comprises the installation lengthminus the engaging length of the connectingpart. For load chains, the E therefore desig-nates the complete rod section.
Special product-related features are to betaken into account as follows:
0
To determine the total length of the rods ina load chain, all the E dimensions are to beadded together. The sum of these is then tobe compared with the total installation length.If the resulting difference is greater than thesum of the engagement depths (X dimensions),the chain selected is appropriate for the totalinstallation height.
For load chains consisting solely of pin con-nections, the minimum installation dimensionfollows from the sum of all E dimensions.

9.2 Regulation of the total installationlength
9.2.1 Turnbuckle function of the connectingthreadsFor length adjustment in installation condition(adjustment of pipe installation position, ac-tuation of loading), the lower connections inconstant and spring hangers provide a turn-buckle function. This way, subsequent adjust-ment of the installation lengths (attachmentrods) within a sufficient range is possible:
➜ for constant hangers type 11, by 113/4 inch [300mm]
➜ for spring hangers type 21, by the adjustment possibility of a turnbuckle, type 62
➜ for spring hangers type 22, by min. 51/2 inch [140mm]
➜ for spring hangers types 25 and 26, the load bearing rod is fed through the weld-on support tube and fixed with an adjustment nut. The adjustment can be made within the scope of the avai-lable threaded length of the rod.
All connection threads are supplied as righthand threads.
9.2.2 Spring supportsFor spring supports types 28 and 29, theinstallation height can be regulated by thesupport tube, functioning as a spindle inde-pendently of the presetting. The necessary load is actuated on installationby screwing the support tube upwards.
9.2.3 Turnbuckle, type 62, tie rod, lefthand/right hand thread, type 65For rigid hanging support arrangements withshort installation lengths, a defined reservelength in the connection parts type 60 and61 usually enables sufficient length adjust-ment. For longer installation lengths, the useof a turnbuckle L/R, type 62, in conjunctionwith a tie rod L/R, type 65, is appropriate.For easy access, this combination should bearranged at the lower end of the load chain.
9.2.4 Rigid struts, type 39The connections in rigid struts type 39 aresupplied as left/right, with fine threading forlength adjustment in the installation conditionas standard.Flat faces on the body of the rigid struts en-able simple adjustment with a wrench.
10. OPERATIONAL BEHAVIOR
10.1 FunctionConstant hangers type 1 are designed so thatin theory no load deviation occurs over thewhole range of action. The total deviationresulting from springs, bearing friction, andfabrication tolerances is held to within � 5%in series production. The load adjustment follows with a level ofaccuracy of 2%.
For spring hangers and supports, the loadalters linearly corresponding to the springtravel. The deviation of the spring force fromtheoretical values, resulting from spring hys-teresis and fabrication tolerances, amounts toless than � 5% within the ordered travel.

11.2 Quality management program, QMPThe QMP is clearly laid out in a quality ma-nagement manual, QMM, and regulates all thequality-assuring activities in the company.The QMM covers the organization as a whole,whereby the observance of rules is monitoredby the independent quality management de-partment QM. The QMM has been compiledaccording to international quality norms andstandards and specifically takes into accountthe regulations according to ASME III - NCA3800 and NCA 4000 incl. NF as well as DINEN ISO 9001 and KTA 1401.
The QMM applies in principle to both the con-ventional and nuclear fields. The extent ofmonitoring of materials and tests, as well asthe documentation, can in each case be exactly adapted to special requirements by theuse of extended QA levels. All internationalrequirements concerning nuclear applicationscan be covered. Corresponding qualificationsare available and are regularly renewed.

11.3 International qualifications
QMP and Processing constitute a single entity!
10.2 Spring relaxation
Conventional helical coil springs under load,depending on time and temperature factors,lose part of their tension by relaxation (sett-ling loss), a loss that is not inconsiderable.If no appropriate measures are taken, forconstant and spring hangers this can in thelong run lead to a reduction in adjusted ul-timate load of more than 10%.
In contrast to common practice, LISEGA onlyuses springs that, through special treatment,permit no settling loss of any significance. In these springs the settling loss normally tobe expected is anticipated via the process ofhot setting from a longer coil length, prod-ucing corresponding prerelaxation.
11. QUALITY ASSURANCE

CONSTANT HANGERS, CONSTANT SUPPORTS, PRODUCT GROUP 1
1.1
To avoid detrimental constraints in the system,thermal expansion in piping and other plantcomponents must not be prevented.
Constant hangersConstant hangers compensate for verticalmovement caused by thermal expansion. Via constant hangers, the respective pipingloads are constantly absorbed and transferredwith no significant deviation over the wholerange of movement.
Significant deviations would act as harmfuland uncontrolled extra loads in the system.
In this case, connection points are especiallyat risk because of unacceptable forces andmoments. It is vital that the constant hangers workreliably and efficiently, as this is decisive forthe operational safety and long life of thepiping system.
Constant hangers - the LISEGA systemFor nearly forty years LISEGA constant hangershave proven themselves convincingly in allkinds of operating conditions. The specialfunctional principle, based on the parallelogramof forces, is patented worldwide and hasfundamental significance in this respect.
Continued development of LISEGA constanthangers on this foundation has led to mat-ured products of superior quality with world-wide recognition.
See the sections “Operational Function”,page 1.13 and “Design Features”, page 1.15,in this regard.

Functional performanceThe specific functional principle of LISEGA con-stant hangers guarantees absolute constancyacross the entire travel range. This is not evenaffected by load adjustment. Only a minorfriction force resulting from tolerances andbearings has to be taken into account as aslight deviation. The hysteresis produced bythis is kept within very narrow limits by thedesign principle and by state-of-the-art manu-facturing procedures.
For normal load settings, deviations in theoperating load for LISEGA constant hangersin series production is kept in practice at � 3% on average. Using a selection process,supply of hangers with a maximum deviationof � 2% is possible.
The generally permissible deviations are laiddown in the following international standards:
➜ MSS-SP 58, USA, max. � 6% referring to operating load.
➜ VGB R 510 L and KTA 3205.3, Germany, max. � 5% referring to operating load.
➜ EN Europa Normenentwurf, max � 5%, referring to operating load. The mean load deviation is limited to max � 2%.
Function testsBefore delivery, each constant hanger is testedfor correct function and set to the requiredload.
The test results are both graphically and digi-tally plotted and recorded. They can be sup-plied on request.
The load setting values are stamped on ariveted aluminum name plate. In addition,the set load is permanently marked on theload scale. Cold and hot positions are markedon the travel scale in white and red respec-tively.
The relevant travel position is directly read-able on the travel scale in mm and inches.The relevant set load can be read from theload scale in kN or lbs.
For function testing, quasistatically actingtest benches with a capacity of up to225000 lbs [1000kN] are available in all the factories. The test benches are inspected at regularintervals by an independent authority.

OPERATIONAL FUNCTION
1.13
Special requirementsStrict demands are placed on constant han-gers to ensure reliable function:
➜ absolute constancy for all load settings
➜ minimum mechanical friction
Likewise, particular requirements are to befulfilled for the continuous monitoring of thepiping system performance:
➜ reliable indicators for set load and travel
➜ adequate and precise subsequent load adjustment if required
The LISEGA functional principleLISEGA’s patented functional principle forconstant hangers provides the ideal condi-tions for fulfilling all requirements. The prin-ciple is based on the interplay of force fromone main spring and the resultant forcefrom two hooked up compensating springs.The directions of force of the two pre-stressed compensating springs are opposedto each other in the form of a parallelogramof forces.
The suspended load acts directly on themain spring via a central load tube . The force of the compensating springs operates as resultant force , via camsand rollers . This force acts additionallyon the load tube. The main spring forceand resultant force change when the loadis moved over the travel range . This is inaccordance with the characteristics of thespring, and the angle and shape of the cams.The individual components are arranged insuch a way that any changes in the resultantspring constancy correspond exactly withthe characteristic curve of the main spring.In this way the force of the main spring isevenly compensated for, providing constantsupporting force.

1Down towards the apex of the cams theresultant force diminishes in proportion tothe increase in the relatively low startingforce of the main spring.
At the apex of the cams the forces of thecompensating springs are cancelled out. The resultant is zero. At this point only themain spring carries the load. Beyond the apex,the direction of the proportionally increasingresultant force of the compensating springs isreversed. It now reduces the relatively strongmain spring force in the same way.
The sum of, or the difference between theforces F1 and F2 at each point in the travelrange = F.
➜ Only the LISEGA functional principle guarantees absolute constancy right from a theoretical basis.
➜ Only the LISEGA functional principle allows a particularly wide load adjustmentrange of 40 - 100% of the nominal load.
Load adjustmentLoad adjustment is carried out by adjustingthe pre-tension of the main spring. Becausethe characteristic curves of the resultantcompensating force and those of the main-spring are identical, only a linear displace-ment of the starting load occurs. The forcevariation achieved by altering the main springpre-tension is the same at every point in themovement cycle. Therefore, the ultimate loadremains constant at each load setting. The
usable travel changes in proportion to theload alterations.
The extremely wide load adjustment rangeenables us to cover a broad range of appli-cations with a compact number of unit sizes.This special advantage is the prerequisite forthe formation of load groups as the basis ofthe LISEGA modular system. In this way,rational series production and warehousingcontrol are made possible.

Connection typesThe connection threads correspond to thestandardized diameter of the relevant LISEGAload group. At the upper connection thethread depth is limited. At the lower end, thenut is used as a turnbuckle for adjusting rodlength.
The shape of the hanger housing allows directseating on existing connection structureswithout extra accessories. In addition, specialbrackets can be attached using the standardtapped holes provided. Constant hangersabove load group 9 (heavy duty) have yokeplates for bolted connections instead ofconnection threads.
Performance rangeConstant hangers and supports are manufac-tured in load groups C - 9 as serialized single-cell units. They can also be coupled togetherfor load groups 8 or 9 as multi-cell hangerswith heavier loads. In this way a standardized range of 20 lbsto 112400 lbs [0.1kN to 500kN] can becovered. Constant hangers are manufacturedin 6 standard travel ranges: 6/ 12/ 18/ 24/30/ 36 inch [150/ 300/ 450/ 600/ 750/900mm] - constant supports up to 12 inch[300mm].
Standards and calculationsComponent design and layout fully complyas regards load capacity, dynamic functionand lifespan with the relevant national andinternational standards and codes. This ap-plies equally to the materials used, weldingtechnology and other processes. Relevantdetails can be found in the TechnicalSpecifications (page 0.9).
SpringsThe springs are decisive for the flawless functioning of constant hangers – the longterm operational safety of these componentsdepends on them. DIN standards form thebasis of the LISEGA coil spring specifications.Details can be found in the TechnicalSpecifications in section 0.

DESIGN FEATURES
Design shapeLISEGA constant hangers are made to a com-pact and symmetrical design. This facilitatesspace saving installation dimensions and theuse of standard accessories. When installingon site, much time and effort is saved bylow unit weight and simple positioning atconnection points. Only one hanging point isneeded for fitting. The load transfer passesthrough the axis of symmetry. Space for ra-dial deflection (lever arm hanger) need not beconsidered. Additional moments posed on thesupporting structure by lever arm units aretherefore avoided. The design enables a directreading of the travel position on a scale of 1:1.
Design constructionA steel housing encases the internal workingparts such as springs and cams. The compactarrangement of these individual parts insidethe housing leads to small external dimen-sions. The housing is designed to be loadbearing and to accommodate LISEGA standardconnecting components.

1Spring relaxationConventional helical coil springs subjected toload and temperature over a period of timelose part of their force (spring relaxation). In the long term, it can cause a reduction inthe adjusted support loads of more than 10%in constant and variable spring supports(see calculation example).
LISEGA only uses prerelaxed springs whichby an artificial aging process allow no signi-ficant settling loss. In a hot setting procedurewith extended coil lengths a correspondingpreplastification is attained. The settling lossnormally to be expected is thereby prevented.
Corrosion protectionConstant hangers are finished with a LISEGAstandard coating system which in conjunc-tion with a metallically pure treated surfaceoffers superior corrosion protection with highmechanical stability. Bearings and pins aremade from stainless steel. All threaded parts and cams are electro-galvanized and yellow chromatized.
The spring coil surfaces are given specialfinishing treatment (see Technical Specifica-tions, page 0.10).
The standard corrosion protection for constanthangers needs no maintenance inside buil-dings, or in areas protected from the weather.For components in the open and in specialcases of operation, a more comprehensivecorrosion protection can be agreed on.

➜ unpredictable random influences on pipe statics
➜ differences between theoretical and actual values of load distribution
A combination of deviations can normally beexpected, which cumulatively can amount toconsiderably high values. This is especiallyunfavorable with long-legged (soft) pipingsystems. Vertical movements can be obstruc-ted here, even on relatively minor individualdeviations, and partially or even totally sup-pressed. Apart from the extra load caused,unacceptable sagging can occur with a rev-ersed slope, supported by spring hysteresisfrom the pressure-loaded system. In additionto possible time yield damage, this wouldfavor dangerous water hammer effects dueto a false incline.
In such cases, a sensible solution would beto complement the “passively” reacting con-stant hangers with the “actively” workingLISEGA servo hanger.Via the hydraulic servo assistance, the pipingis now actively supported in its movementat every predetermined height.
THE LISEGA SERVO HANGER
ApplicationIn the ideal situation the weight of the pipingis almost balanced out with the set load ofthe constant hangers. The sum of deviationspresent and the additional stresses in thepiping system thereby caused then remainwithin the permissible harmless range.In certain cases, total deviation can exceedpermissible levels. In the form of secondarystresses it can considerably reduce the lifespan of the piping or its connections in thearea of creep strength depending on time.
Deviations can occur due to:
➜ wall thickness tolerances of the pipes, if these are not weighed individually and weight differences are not taken into consideration
➜ insulation weights not exactly determinable in advance
➜ mechanical friction and manufacturing tolerances within constant hangers (permissible � 5%)
➜ relaxed springs in constant hangers

Operating instructionsInstallation and commissioning instructionsand maintenance recommendations are sup-plied on delivery.
Design and functionThe basis for the servo hanger is a standardType 11 constant hanger. To overcome loaddifferences, it is additionally fitted with ahydraulic auxiliary device providing additionalactive force in both directions (servo assis-tance).
As a control parameter, the temperature ofthe piping to be supported is normally used.The relevant temperature is converted elec-tronically into the corresponding position. Inthe actual / theoretical value comparison pro-cedure, the control provides for a regulatedadvance towards the vertical theoreticalposition.
Electro-hydraulic controlThe hydraulic unit and the electronic controlare housed separately from each other in aswitchgear cabinet mounted near the servohanger (max distance 52 feet [16m] ).The hydraulic piston controlling the move-ment is located in the load tube of the con-stant hanger.
Automatic safety switchThe electrohydraulic control is designed insuch a way that only the servo assistance islost if there is an operational breakdown, e.g. a power failure. The unit itself wouldcarry on operating in the normal way as aconstant hanger.For deviations in theoretical (temp.) / actual(travel) a tolerance range can be adjusted.The control shuts off automatically if thedeviation lies outside these values.
Manual shut offFor possible maintenance work in the systemor at the boiler, the servo assistance can beshut on or off by hand.

2.1 Constant hangertypes 11 C3 .. - 11 96 .. (single cell)The upper connection is supplied as internalthread with limited screw engagement. The lower connection is a spherical load nutwhich can angulate through a minimum of 4°in all directions. The connection threads arefilled with grease and sealed with plastic caps.
2.2 Constant hangertypes 12 82 - 14 96 (multi cells)The upper connection is provided as standardin the form of a lug for a connecting pin.The lower attachment exists of several ten-sioning bolts connected by a yoke plate.
2.3 Constant hangers (seated)Constant hangers of all sizes can be directlyseated. They can also be supplied with serial-ized brackets type 71. The brackets can bebolted on at works or on site according toorder using the precision fit holes provided.The base plates of the mountings can be eitherwelded or bolted to the mounting surface.
2.4 Constant supports type 16Constant supports follow the same designprinciple as the constant hanger. Instead ofthe lower connection, they have an uppersupport tube with a screwed-in adjustingspindle and load plate.
3. InstallationWhen installing, the rules for the InstallationInstructions for Piping are to be adhered to.Special attention must be paid to the desiredinstalled position of the hanger rods in thewhole support chain. Two possibilities areusual practice:
1. The hanger rods are to be installed at anangle in accordance with expected horizontaldisplacement of the piping. It is expected thatthe rods become vertical during operatingconditions.
2. The hanger rods are to be installed ver-tically for better control. A controlled angledposition during operating conditions is thenpermitted.
In all cases there should be a unified set ofrules for the whole plant.
Attachment rods and points must be connec-ted under actuation of load.
3.1 Constant hangertype 11 C3 - 11 96 (single cell)Transport lugs or other installation aids canbe screwed into the threaded holes providedon the sides. After deblocking the hangers(see Point 4), the blocking plates should bebolted on here for storage. For constanthangers with type 71 brackets, the hangersare supplied with transport lugs instead ofthe upper connection. The lugs can also ac-commodate the blocking plates. When rem-oving the blocking plates from constanthanger types 11 82 to 11 96, care must betaken that only the larger circlip is removed.For connection to the connecting rod, caremust be taken that the lower rod is screwedinto the load nut at least up to the controlbore. A further screw engagement of 12 inch[300mm] is provided.

3.2 Constant hanger types 12 82 - 14 96To install the hangers, the side openings ofthe upper yoke plate can be used for lifting.On hangers fitted with brackets, the upperyoke plate is substituted by a transport lug.
Constant hangers types 14 82 - 14 96(4 - cell design) are supplied with a transportsafety device marked in red along the centeraxis. This serves to provide additional mid-blocking to the blocking pin on an unloadedhanger.
The transport safety device must not be loosened until after the complete installationof the hanger simultaneously with the remo-val of the blocking plates.
For this purpose the red locknut is removedat the lower end using a box spanner. Bothparts are to be stored in the same place asthe blocking plates. When making the load-actuating connection, care must be taken thatthe lower load anchors are screwed into thelower load nuts at least up to the controlbore. The installation dimension of the loweryoke plate can be extended with the loadnuts by up to 97/8 inch [250mm] or shortenedby up to 23/4 inch [70mm].

4. Removing the blocking devices
4.1 RequirementsThe correct deblocking of the constant han-gers as per the following instructions is deci-sive for the subsequent flawless functioningof the piping system.
The blocking devices should only be removedimmediately before commissioning. The blocking devices must be removedsystematically, i.e. from fixed point toconnection or from connection to connection.
Prior to this the whole system should bechecked as per Item 3 in these installationinstructions.
4.2 Theoretical and actual conditionIf it has been ensured that all connectionsare actuated by load, the load suspended iscompletely taken over by the constant han-gers or supports. If the actual load corresponds to the instal-led load and the piping system shows nosigns of constraints, the planned equilibriumhas been achieved. The travel stop platescan now be removed.
In practice, however, slight constraints andhence certain load displacements in thepiping system can hardly be avoided. Thetheoretically determined loads can also showconsiderable tolerances. Deviations resultingfrom this can lead, according to increased ordiminished loading, to a corresponding jam-ming of the blocking pin in the upper orlower part of the blocking plates.

4.3 Load distributionThe travel stop plates must never be removedby force!By loosening or tightening the connectingrods with a few turns of the load nut for con-stant hangers, or adjustment of the supporttube for constant supports, the locked-upstress in the piping can be compensated sothat the blocking pin is free.However, the geometrical layout of the pipingmust not be altered when balancing thesestresses.Because the adjustment of one position canlead to stressing at another location, thisprocedure must be repeated if necessary atdifferent points.For thorough control, we recommend as amatter of principle removing the travel stopplates only after all the blocking pins are free.

4.4 Load correctionIf the blocking pins jam, and cannot be freedwithout displacement of the piping, significantdeviations in the piping load can be assumed.
The adjustment bolts of the constant hangers and supports can then be corres-pondingly set. Once more, this should be donefrom position to position, as described inpoint 4.3. If this is done correctly, load differ-ences can be practically balanced out by thismethod. Any load adjustments must as a mat-ter of principle be agreed on with the tech-nical department responsible for the pipingsystem. Any new load setting values shouldbe indicated on the load scales and recorded.
4.5 Installation devicesWith all hangers, tightening or loosening theconnecting rods, as well as load adjustment,can be done by hand. With hangers and sup-ports for higher load groups, however, thisoperation may need considerable force. To make this easier, an installation aid canbe provided which takes on the load hydrau-lically with the aid of a hand pump.
4.6 CommissioningBefore commissioning it must be checkedthat each hanger allows the expected pipingmovement.The hanger travel can be read directly fromthe position of the blocking pin in the guideslots on the travel scale.If required, for example when carrying outrevisions, hangers and supports can beblocked again in any travel position. This isdone by mounting and securing the blockingplates onto the blocking bolt.
5. Control and maintenanceThe correct performance of the constant han-gers and supports can be checked in all ope-rating situations by noting the position ofthe blocking bolt.Under normal operating conditions no main-tenance is required.

Spring elementsTo compensate for slight vertical displace-ments in the piping, spring components areused as supports. The functioning of thesecomponents is based on preset helical coilsprings which exert a variable supportingload over the whole range of movementcorresponding to the given spring character-istics. Load variations resulting from this arelimited through corresponding specificationsbased on stress calculations for the piping -this depends on the sensitivity of thesystem.
The fundamental principles relevant for thefunction of the spring components are foundin the MSS SP 58 and VGB R 510 L guide-lines. See Technical Specifications, page 0.5.
LISEGA spring hangersVarious versions of spring elements, ideallysuited to whatever structural requirementsexist, are available. The optimum choicedepends on the installation situation.
Spring hangers, type 21This type, the one most frequently used, isfitted with an upper connection for suspen-
sion. It is installed whereverthe surrounding locationoffers a suitable connectionpoint and sufficientspace. The upperconnections can beuniversally adaptedwith standard com-ponents to any given
situation.
SPRING HANGERSSPRING SUPPORTS
2.1
Spring hangers, type 25This type is frequently used for
its simple installation, just sea-ting it on the existing steel. Theconnection is made by a rodpassing through the unit.
Spring supports, type 29If the installation location doesnot permit sus-
pension, then this model is asuitable alternative as a“prop” support. Where thereis considerable horizontaldisplacement of the supportload, and steel slides onsteel, lateral forces canunder certain conditionshave an adverse effect onthe operation of the sup-port system. To take precautionsagainst this, the use of PTFE bearings isrecommended. In this case the counter bea-ring should have a stainless steel surface.

To prevent constraints inthe system, thermalexpansion in the pipingand other piping compo-nents must not be hinde-red. The piping must there-fore be supported in a cor-respondingly elastic man-ner.
2.2
Angulating spring supports, type 20Unlike the spring support type 29,horizontal displacement can betaken up almost free of lateralforces by this design. This way that constraining fric-tional forces are completelyexcluded at all levels of move-ment, vertical and horizontal.
Sway braces, type 27These particular components act both intension and compression and are used tostabilize the piping and other plant com-ponents. An additional damping effect isobtained at the same time. The connectionparts correspond with those of ProductGroup 3.
With LISEGA sway braces, type 27, the following adjustmentscan be made:
➜ load presetting➜ free stroke➜ installation dimension
See also Installation and OperatingInstructions, page 2.17
Load setting and blockingSpring hangers and supports are preset at theworks to the installation load and blocked inboth directions of movement. Blocking isnecessary to take up additional loads duringpickling, flushing, or hydrostatic tests. The factory settings are carried out on elec-tronically controlled test benches:
➜ with spring hangers, values set at the factory are stamped onto a riveted nameplate.
➜ the installation position is marked on the travel scale.
➜ cold and hot settings are marked on the travel scale with a white and red sticker respectively.
➜ the blocking device can be blocked in any position. The blocking pieces can be reinserted in any required position.
Spring hangers and supports should be setin such a way that the spring load and thepiping weight correspond with the cold loadposition.The corresponding hot load position resultsfrom the theoretically determined pipe move-ment (travel) and the spring rate.The load difference between the cold andhot positions acts on the piping as a reac-tion force and is limited by the relevantdesign specifications.
Generally, the max. permissible load devia-tion amounts to 25% of the operating load.
Above and beyond that, constant hangersexerting a constant supporting load over thewhole travel range are to be used.
Selection of spring hangersA decisive factor for the reaction force is thestiffness of the spring rate value of the res-pective coil springs. To cover the widest pos-sible field of application using spring han-gers, the load ranges are divided into 5 tra-vel ranges.
Please see Technical Specifications page 0.13for details of usage. See also the selectiontable, pages 2.3 and 2.4, as well asInstallation and Operating Instructions, page2.15.

SELECTION CRITERIA FOR SPRING HANGERS AND SUPPORTS
Permissible force variationThe permissible force variation betweencold load (installation load) position tohot load (operating load) position islimited internationally by common speci-fications for pipe stress analysis to max.25% of the operating load.
Maximum working travelAdditionally, to preclude functionalimpairment due to instability from extralong springs, a working travel of maximum 2 inch[50mm] should not be exceeded.
Spring ratesTo cover as wide a field of applicationsas possible while adhering to thesestandards, LISEGA spring elements aredivided into 5 travel ranges with cor-respondingly different spring rates.
Extra long springsTravel ranges 4 & 5 relate to extra longsprings and should only be used aftertechnical evaluation of the whole situ-ation, especially in sensitive pipingsystems.
Design typesThe selection of the suitable designtype depends upon the respective sup-port configuration or installation situ-ation.

2.6 Sway braces, type 27Sway braces are provided at the top with alength-adjustable ball bushing joint and atthe bottom with a fixed lug suitable for con-nection to weld-on bracket type 35 or dyna-mic clamp type 36 or 37. Presetting of theload and if necessary the free stroke arecarried out at the works in accordance withcustomer requirements.
3. InstallationWhen installing, the rules given in InstallationInstructions for Piping must also be observed.Special care must also be given to theinstalled position of the connecting rodsover the whole support chain. Two possibili-ties are the norm:
1. The connecting rods are to be installed atan angle corresponding to the horizontal dis-placement to be expected. A vertical positionof the rods is expected under normal opera-ting conditions.
2. The connecting rods are to be installedvertically for easier checking. A controlledangled position under normal operating con-ditions is thereby permitted.
In each case there should be unified rulesand regulations for the whole plant.
Connecting rods and points must be actuatedby load at connection points.
3.1 Spring hangers, type 21Connection is made by screwing the connec-ting rod into the upper threaded connectionhole in type 21, and by screwing the lowerconnecting rod into the turnbuckle. As a tension range and length adjustment,the turnbuckle length available in the hangercan be used for the connecting rod.
3.2 Spring hanger, type 22Connection is made by pinning the lug to theupper attachment point and by screwing thelower connecting rod into the turnbuckle. As a tension range and length adjustment,the turnbuckle length available in the hangercan be used for the connecting rod.
2.17
3.3 Spring hangers, type 25 & 26These spring hangers are set on beams andcorrespondingly positioned. Once the preciseposition is defined the unit should be securedagainst horizontal movement. The load actu-ated connection is made via the connectingrod, which is led throught the support tubeand tightened with a nut.
3.4 Spring supports, type 28 & 29After positioning, these spring supports areconnected to the structure by bolting or wel-ding the base plate to the structure. Loaddistribution is applied through the loadplate or through one or more adjustableload tubes.
3.5 Angulating spring supports, type 20The angulating spring supports are connec-ted to the structure after correspondingpositioning by welding the lower weld-onbracket. Load distribution is applied throughthe upper weld-on bracket via the pinconnection to the height-adjustable loadtube.
3.6 Sway braces, type 27After positioning of the connection points,the weld-on brackets are attached andconnection is made through the connectionpins of the brackets or dynamic clamps. The ball bushing joints allow a � 11/2 inch[37.5 mm] adjustment of installation length.
4. Removing the travel stopsThe spring hangers and supports should onlybe deblocked when the set load is fullyapplied to all the supports, which form onesystem. If this is the case, the travel stopscan easily be removed. If the travel stops arejammed, the load actually applied does notcorrespond with the theoretical adjustedload. (See Installation and OperatingInstructions, Constant Hangers, page 1.23,item 4, in this regard).

5. Load readjustment
5.1 Spring hangers, spring supportsFor spring hangers the load can be readjustedby loosening or tightening the threaded rodsat the lock nut. For spring supports, the loadcan be readjusted by a corresponding adjust-ment of the load tube.Under all circumstances, however, the approp-riate technical department must be consultedbefore attempting any load readjustment.
5.2 Sway braces, type 27Load readjustment is made by rotating thethreaded tube (A). The large counter ring (B)is loosened to do this. In order to maintainthe E dimension, the resulting gap is com-pensated for by readjustment of the guidetube.
For sway braces, a free stroke can be set.To do this, the guide tube (C) opposite theinner guide rod (D) is to be unscrewed (loosen middle lock nut). The working travelreduces in the compression direction inaccordance with the free stroke selected.
6. CommissioningBefore commissioning it must be checkedthat each hanger or support allows the pre-calculated movement of the piping.The working travel of the hanger or supportcan be read off at the bottom edge of thespring plate as travel in the blocking slots,and read directly off the travel scale.
7. Checking and maintenanceThe correct functioning of the spring hangersor supports can be checked in all operatingsituations by noting the position of thespring plates. Under normal operating conditions no main-tenance is required.

PRODUCTGROUP 3
Product group 3 componentsPipe supports specially designed for thepurpose are necessary to absorb and trans-fer loads from dynamic events. With ProductGroup 3, LISEGA provides a comprehensivesystem whereby all fields of application arecovered by the corresponding ideal compo-nent. This enables users to exploit optimumconcepts.
The LISEGA Product Group 3 includes thefollowing main products:
➜ shock absorbers, types 30 and 31➜ energy absorbers (E-Bars), type 32➜ rigid struts, type 39
A comprehensive selection of connection pos-sibilities is available for the correct installa-tion of the main products:
➜ installation extensions, type 33➜ weld-on brackets, type 35➜ dynamic pipe clamps, types 36 and 37
In accordance with the LISEGA modularsystem, the connecting parts are designedto be compatible and are subject to uniformcalculation criteria. A generally applicabletable of permissible loads can be found onpage 0.5 of the Technical Specifications.
The fundamental calculation procedurescomply with international regulations andstandards and are certified by practical typeand suitability tests. Design Report Summaries in accordancewith ASME III NF are available.
Dynamic eventsWhenever unplanned dynamic events occur,LISEGA Product Group 3 supports have thejob of protecting the piping or other com-ponents affected from any damage.
Undesirable abrupt movement of the com-ponents in the system can be caused by:
A Internal excitation, such as:
➜ pressure shocks from valve operation➜ water hammer➜ boiler events➜ pipe breakage
B External excitation, such as:
➜ wind load➜ seismic events➜ aircraft impact➜ explosions
Components affected can be:
➜ piping➜ pumps➜ valve assemblies➜ pressure vessels➜ steam generators
To avoid unacceptable ten-sion and moments in thepiping system, unplanneddisplacement in piping orother plant components mustbe eliminated. However, ther-mal movement must not behindered in any way!

3Shock absorbers, type 30, 31The use of shock absorbers (snubbers) ispreferred in thermally operating pipingsystems. In a dynamic event, shock absor-bers instantaneously form a practically rigidrestraint between the protected componentand the structure. Resulting dynamic energycan at once be absorbed and harmlesslytransferred.
Through the special function of the shockabsorbers, thermal displacements during nor-mal operation remain unhindered.
Energy absorbers, type 32If only slight operational movement is to beexpected at the load application point, thenas a rule energy absorbers can be used.These components allow a small amount ofmovement, which is limited by an adjustablegap in the end positions. The componentsaffected are protected from overload because,due to the design, the dynamic energy intro-duced is transformed into deformation energy.
Rigid struts, type 39If no operational movement is to be expec-ted, e.g. at so-called “zero positions”, thenrigid struts are used. They form rigidrestraints from attachment point to attach-ment point and do not allow axial move-ment. However, as they have angular bear-ings, limited angular movement is permitted.

PRODUCT GROUP 3RECOMMENDATIONS FOR USE
Product Group 3 components are dynamicallystressed. In their use, the following pointsmust be observed for effective functioning:
1. Where the design of dynamically fixedpoints is concerned, the stiffness of the supporting system as a whole, i.e. of allcomponents in the support chain, must beconsidered.
2. In the selection of unit sizes, the total ofall loadings avising must be taken intoaccount.
3. For given loads it must be made clear,beyond any doubt, which level of design load(H, HZ, HS, and/or Level A,B,C,D) the datacorresponds to. The table of permissible loadson page 0.5 of the Technical Specificationsmust be observed.
4. The stroke length of shock absorbersshould not be fully exploited. An overtravelsafety margin of 3/8 inch [10mm] at eachend of the snubber should be maintained.
5. When arranging the components, sufficientlateral freedom should be allowed so thatthere is no jamming at connection lugs.
6. When shock absorbers are arranged inparallel, it is recommended that load re-serves be considered. Instead of 50%, ineach case it is recommended that bothshock absorbers be designed to take 70%of the total calculation load.
7. The installation drawings should clearlyindicate how much freedom of angulationmay be required by the components.
8. Any necessary torque values for threadedconnections in the structural attachmentsshould be indicated.
9. Before commissioning the plant, all sup-port points should again be visually inspec-ted.
10. The LISEGA instructions for commissioningand inspection, as well as the maintenancerecommendations, are to be observed.

LISEGA shock absorbers have stood the testof time in practical applications for overthree decades, and thereby proven theiroutstanding reliability. Extensive operationalexperience has, through constant furtherdevelopment, led to a matured product, uni-versally respected and leading worldwide.
Access to shock absorbers after installation isgenerally difficult and, because of possibledanger from radiation when installed innuclear power plants, involves stringentsafety regulations for personnel. The highestdemands are therefore made on reliable andmaintenance-free continuous service.
For the reliable operational safety of shockabsorbers, the quality of the following criticalcomponents, together with the functional prin-ciple and whole design, is a decisive factor:
➜ sealing systems➜ piston and rod guides➜ hydraulic fluid➜ sliding surfaces➜ corrosion-resistant interiors➜ control valve system
SHOCK ABSORBERSTYPE 30, 31
The most frequent causes of failure in shock absor-bers are prematurewear and tear andcorrosion. For this reason LISEGA shock absorbersare manufacuredfrom non-corroding materials and any form of metal to metal contactis precluded by the use of special guide bands.
At LISEGA, the sealing system, guidings andhydraulic fluid are certified through reliablequalification procedures to give at least 23years trouble free operation in nuclear powerstations under normal operating conditions.
The following qualities have led to the recog-nized superiority of LISEGA shock absorbers:
➜ non-corroding materials➜ special sealing systems➜ vibration proof guide systems➜ pressurized self-contained hydraulic system➜ dynamic function➜ exchangeable control valves (Type 31)➜ 23 years approved maintenance-free
operation➜ 40 year lifespan➜ certified by ASME - NCA 3800
➜ certified by TÜV qualification testing

INSTALLATION EXTENSIONSTYPE 33
Installation extensions type 33 18 18 to 33 03 12
Type 33 extensions are usedto bridge larger installationlengths, thus avoiding struc-tural adjustments on site.
Connection to the shockabsorber or energy absorberis made at the cylinderbase. Standard threadedconnections allow the simple substitution of exten-sions for standard connec-tion lugs. The same appliesfor special connections,helpful when exchangingunits made by other manu-facturers, because this wayexisting structural con-nections can remain (see page 3.8).

It is a well known fact that most earliergeneration shock absorbers do not fulfillcurrent demands and specifications. The result is failure, and huge maintenancecosts. Considerable savings can be made byreplacing these units with LISEGA shock orenergy absorbers (E-bars).
So that connections already existing on sitecan still be used, a range of special connec-tions is available.

absorbers endure these loads whilemaintaining their functional integrity.
The special guide systems of the shockabsorbers make them largely resistantto permanent cyclic operating loads.This is confirmed by proven practicalexperience.
It has to be considered that the rangeof possible influential parameters suchas frequencies, amplitudes, oscillationshapes, impact directions, mono- andmultiaxial effects, as well as possibleoverlapping, permit no uniform definitionof continuous operational vibration.

MODE OF FUNCTION
Dynamic eventIn the event of a sudden shock, an instan-taneous, secure and almost rigid connectionis produced between the supported com-ponent and the fixed point on the structure.The resulting dynamic loads are at onceconducted into the structural connection anddissipated without any harmful consequences.
Normal operational movements of piping andother components remain however unhindered.
Moments of force can often change directionat random within the framework of complexoscillation spectra. The response frequencyrange for LISEGA shock absorbers is 0.5 -100 Hz.
FUNCTION
Control valvesThe function of LISEGA hydraulic shock ab-sorbers type 30 is controlled by the main con-trol valve (B), axially mounted within thehydraulic piston (A).During the piston movement (� 4.72inch/min [2mm/s]) the valve is kept open by
spring pressure, and hydraulic fluid flows fre-ely from one side of the piston to the other.During rapid piston movement (approx. �4.72 inch/min [2mm/s]) above the speedlimit, the resulting fluid flow pressure on thevalve plate closes the main valve. The flowof the hydraulic fluid is stopped and move-ment blocked. The compressibility of thefluid cushion has a softening effect on therestriction of the piston. This preventsdamaging load spikes.For movement in the compressive direction,the compensating valve (D) closes almostsynchronously with the main valve.
If the pressure on the closed valve subsides,e.g. through reversal of the direction of move-ment, the main control valve opens automa-tically when the fluid force falls short of thespring force.
BypassTo prevent the valves from jamming in theblocking position, they are fitted with abypass system.

This allows limited piston movement undercontinuing load and ensures safe opening ofthe valves by rapid equalization of pressurein both cylinder chambers. The compensa-ting valve works synchronously with themain valve in the same way.
ReservoirFor both variable piston rod positions as wellas for changes in hydraulic fluid volume caused by temperature changes, volume com-pensation takes place through a coaxiallymounted reservoir (C). The link between thereservoir and main cylinder is regulated bythe compensating valve (D).
Large bore shock absorbers type 31The function of the LISEGA shock absorbertype 31 is fundamentally the same as for type30.The special dimensions, however, require adifferent design arrangement of the reservoir(C). The valve assembly also differs.
The valves (B) themselves operate similarlyto those in type 30. The circulation of thefluid is also blocked by closure of the corres-ponding valve in each respective direction ofmovement. This happens whenever a flow-

speed limit is exceeded. Because the valvesare directly linked to the reservoir, no specialcompensating valve is needed.
Recurrent testingTo facilitate routine maintenance, the controlvalve system is designed for removal with theshock absorber still in place. The valves canthen simply be replaced in the event of arecurrent test by a previously qualified set ofvalves. A special shut-off device is used toprevent loss of oil. The original valves canthen be remotely tested in a surrogate snub-ber and made ready for use again.

SHOCK ABSORBERSDESIGN CHARACTERISTICS
3.13
Design characteristicsThe shock absorbers are closed systemswith no external threaded pressureconnections. Individual parts of the unitare assembled without welding bymeans of precision fits and threadedconnections and secured mechanically(see Fig. 3).
For protection against corrosion, LISE-GA shock absorbers are made exclusi-vely from non-corroding materials. Theconnections are made of galvanizedcarbon steel. The guides on piston rods and pistonsare made from a special wear-resistantnon-metallic material (see Fig. 2).
The fluid reservoir is sealed from theatmosphere by a preset piston, so thatslight overpressure in the hydraulicsystem constantly maintains a slightpresetting of the seals.
The control valves are decisive for thedynamic operation of the shock absorber.To achieve high operational accuracy,the valve parameters have been opti-mized by extensive testing and specialcalculation models.
Seals The sealing systems play a vital role inthe long term function of a hydraulicshock absorber. Together with the hyd-raulic fluid and guide bands, the sealsform part of the non-metallic compo-nents of the shock absorber and aretherefore subject to natural ageing andwear. The most important requisite fora lasting sealing effect is the selectionof the right sealing material. A goodmemory for shape retention (compres-sion set) or lowest possible relaxation oftension is thereby an absolute essential.
For optimum exploitation of materialcharacteristics, the shape of the sealsand the design of their locations arealso important.
The optimum combination of the following factors is decisive for functional efficiency:
➜ temperature resistance➜ radiation resistance➜ abrasion resistance, especially
at high frequency vibration➜ good memory for shape retention➜ good dry running qualities➜ limited diffusion tendency into the
metal surfaces ➜ minimal stick/slip drag effect
The material which best meets these requ-irements is a special compound on thebasis of the fluor elastomer VITON. To exploit the special characteristics tothe fullest extent, the following criteriamust also be considered:
➜ special design shapes➜ backing compound materials➜ optimum mixture consistency➜ optimally balanced hardness➜ precision in gliding surfaces➜ design of locations for defined
presetting of seals
Commercially available seals in shockabsorbers do not fulfill these require-ments, and as experience has shown,lead to premature failure. For LISEGAshock absorbers, a specific sealing sys-tem was developed as early as 1984 incooperation with a major seal manufact-urer. Since then, these seals havedemonstrated their worth in practicalapplication.
Alongside other successful qualificationprocedures through artificial ageing andfatigue tests, a qualification test proced-ure was carried out on LISEGA shockabsorbers in 1992 by order of a majorEuropean nuclear utility. The tests cer-tified a maintenance free service life ofat least 23 years in nuclear powerplants under normal operating condi-tions.
Control indicatorsThe piston position of the shock ab-sorbers can be read from all sides bychecking the scale rings on the body ofthe cylinder. The sturdy stainless steelshroud connected to the piston rod pro-tects it from mechanical damage, dirtand heat and also serves as an indicator.
The fluid level of the reservoir is indi-cated by the position of the reservoirpiston. A sight glass can be used forchecking the minimum level in type 30.Type 31 has a marked indicator rodattached to the base of the externalreservoir.

3SHOCK ABSORBERSFUNCTION TESTS
LISEGA applies a test procedure using the verylatest technology. The test benches operate asdynamic hydro pulse units, with either force-controlled or travel-controlled excitation asdesired. The frequency bands range from 0.5 - 30Hz and the test loads from 100 - 1100000 lbs [0.5-5000 kN]. Altogether,seven test benches of various sizes are avail-able for LISEGA in different factories. At customers’ request, they are frequently usedon site as mobile units. Several test bencheshave been supplied to different countries to

Shock absorbers are pre-cision-made, safety-relatedcomponents. Correspondingcare must therefore be takenwhen handling them. For the flawless functioningof the shock absorbers it isessential that the followinginstructions are observed.
Transport and storageShock absorbers and related componentsshould be stored in closed rooms and pro-tected from dirt and damage. Transportationmust therefore be carried out with great care.LISEGA recommends that the shock absorbersremain in their original packing until just bef-ore installation. Any damage during shipment,off loading, on site transportation or instal-lation must be reported to the manufacturerimmediately.
Delivery conditionShock absorbers are supplied as fully oper-ational units, complete with hydraulic fluid,ready for service. The connecting lugs fortype 30 are connected at one end with thebase, at the other with the piston rod andsecured by locking bolts. For type 31 the bottom end lug and cylinderbase form a unit.
LISEGA shock absorbers are made entirelyfrom non-corroding materials, so they needno additional surface treatment. The threadedconnecting lugs are electrogalvanized andwhite chromatized.
Type 35 weld-on brackets are supplied sepa-rately, including fitted pins. Their surface hasa protective coating of weldable primer.
For transportation, type 30 shock absorbersare supplied packaged individually in pur-pose made boxes with pistons fully retrac-ted. Type 31 are fixed on special woodenskids.
For these unit sizes, the actual installationdimensions are preset at the factory.
InstallationShock absorbers must be inspected for da-mage before installation. Also, the connec-ting lugs must be checked for tight fits. Thestructural attachments on site and weld-onbrackets must be completely welded. Thearrange-ment of the weld-on brackets mustbe such that the maximum angular displace-ment takes place in the direction of thegreatest thermal expansion in service.Lateral displacement is limited to a maxi-mum of � 6°. Any twisting of the weld-onbrackets against each other should be pre-vented because of the limitation on move-ment resulting from this.
All welding at the connections or in theirvicinity should be completed before installingthe shock absorbers.
For installation, type 30 shock absorbers mustbe set at the required installation length (theconnection pin to connection pin dimension)by extending the piston rods. This must bedone slowly, smoothly and below the lockupvelocity to avoid blocking the shock absor-ber. Smaller types can be extended by hand.The weight of the larger shock absorbers canbe exploited to help extend them by hangingthe unit to the connecting lug of the pistonrod.
The shock absorbers can be installed in prac-tically any conceivable position. The pistonrod should be connected to the heat con-ducting component to dissipate, via the pro-tective shroud, any heat from radiation.
The installation position of the absorbersshould be so selected as to offer easy accessto the sight glass for fluid inspection duringservice checks.

3Welding the weld-on bracketsThe following procedure is recommended forthe welding of weld-on brackets:
The minimum weld seam thickness “a“ fortype 35 weld-on brackets is dependent onthe angular displacement and . A permissible stress of 13.05 ksi [90N/mm2]at load case Level A formed the basis of thecalculation.
If the angular displacement increases to90°, the permissible loads are reduced byapproximately 15% at a constant weld seamthickness (a min at = 45°).For permissible loads, see load table inTechnical Specifications, page 0.5
Welding procedure1. Remove pins from weld-on brackets2. Preheat weld-on brackets, from
type 35 79 19 onwards, to 212°F [100°C]3. Use base electrodes4. Welding should be performed in layers
to avoid welding distortion. (For sequence, see diagram)
5. Allow bracket to cool to 212°F [100°C] after each welding layer

The connections to the various attachmentstructures must be form-fit for load actu-ation. All threaded connections in the flux offorce must be tightened with sufficient torque.
If, after installation, any welding on theattachment structure is performed near theinstalled shock absorber, care must be takenthat no welding current strays through thebody of the snubber.
After installing the complete system, it isrecommended that each unit be inspectedfor the following:
A. Correct fitting of form-fit connections forload actuation (locking screws on the connec-ting lugs, secure pins, threaded connec-tions).
B. All installation points must be checkedfor adequate freedom of movement duringthermal expansion. Care must be taken toallow the connecting lugs to move freely inthe connection brackets and care also takento prevent the piston from reaching the endposition.
For the piston position, a safety zone of 10mm at each end of the cylinder stroke isrecommended. The position can be read fromthe travel scale.
Before commissioning the plant, a full visualinspection of all shock absorbers and instal-lation situations is recommended.

For normal operating conditions shock absor-bers are designed to function for the entire40 year life of a plant. The seals and hyd-raulic fluid should be changed at least onceduring this period, at the latest after 20years.
However, under certain conditions (extremestresses) shock absorbers can experience pre-mature ageing and increased mechanical wear.Preventive maintenance is recommended inorder to make sure the shock absorbers re-main fully operational and reliable. This main-tenance is the responsibility of the plant ope-rators.
Measures
1. Regular inspection -visual inspection, once per year
2. Extended inspection -function tests, 12 years after commissioning at the latest.
ImplementationInspection and maintenance work should becarried out by specially trained personnel.LISEGA servicing specialists can do this ifrequired. For dynamic function tests, qualifiedtest benches which can also be brought tothe plant are available.
1. Regular inspectionRegular inspection should involve a visualinspection carried out once a year on all unitsinstalled. The first inspection should takeplace immediately before commissioning.
During the regular inspection, not only theshock absorbers must be inspected, but alsothe environmental conditions and installationsituation. The check list should include thefollowing points:
➜ all units to be inspected, noting installation position
➜ planned operational connection displacements
➜ special environmental or operating conditions.
➜ any maintenance work previously carried out.

SHOCK ABSORBERSMAINTENANCE RECOMMENDATIONS
Shock absorbers are com-ponents of great safety-related significance for aplant. They offer protec-tion to the piping systemand other componentsagainst dynamic over-loading due to unplannedload events. As these areunpredictable, the comp-lete functional safety of theshock absorbers must beguaranteed at all times.
3.18
The following should be checked at theinstalled position:
➜ Conformity of name plate data with check list.
➜ Correct form fitting of all connections for load actuation
➜ Correct freedom of movement of shock absorber during operating displacements
➜ Position of main piston rod as regards sufficient stroke, including travel reserve (minimum 3/8 inch [10 mm] ).
➜ Exterior condition of shock absorber for any damage or leakage.
➜ Surrounding area for possible signs of unusual operating conditions, e.g. increased temperature
➜ Fluid indicator level
As long as the reservoir piston cannot beseen through the sight glass there is suffi-cient fluid in the reservoir. If the piston isvisible, it must be assumed that fluid hasbeen lost.
Observations and findings are to be recordedon the check list and if required, recommen-dations for corrective action made.
2. Extended inspectionAn extended inspection is carried out after12 years of operation, whereby a number ofinstalled shock absorbers (min. 2 units pertype) are subjected to an additional functiontest. After successful testing, the shock ab-sorbers can be reinstalled for further service. In the event of deviations in performance,the shock absorber in question should bedismantled and the function-related parts in-spected. The plant operators are responsiblefor taking and documenting any correctivemeasures.
The scope of testing and the selection ofshock absorbers should be agreed on by therelevant plant department and the serviceengineer responsible. Special considerationis to be given to various stress factors (temperature, radiation, loads, operationalvibrations).
The timing and scope of the next ExtendedInspection is to be decided on the basis ofinspection results recorded.
After approximately 20 years of operation atthe latest, it is recommended that the hydraulicfluid and seals are replaced in all shockabsorbers. Following this work, carried outby trained personnel using original LISEGAspare parts, and after successful functiontesting, the shock absorbers can be usedagain for a further 20 years.

Instability caused by twisted clamps of thefrictional grip type (fig. 1) is especially dan-gerous. Because of the unavoidable creepcharacteristics of preset metals a lasting fric-tional grip cannot be maintained at hightemperatures by way of simple bolt preset-ting. Even oversize boltings do not solve theproblem, because on corresponding preset-ting they would cause impermissible contrac-tion of the pipe (“pipe squeezer”).
➜ A typical fault is too soft a clamp design (fig. 2), where the necessary stiffness is not attained.
➜ Care should be taken that the connec-tions on the pipe clamps fit snugly.
➜ So that no constraints arise, sufficient room for lateral movement on displacement in the piping system must be guaranteed.
Prevention of twisting through shear lugsTo prevent twisting, LISEGA recommends onprinciple the use of shear lugs with dynamicpipe clamps (fig. 3, 5, 6). This way, definedand verifiable behavior is ensured.
The lugs maintain the position of the pipeclamps in the expected direction of force andare not subjected to any significant load(fig. 5). Even in the load case, no significantlateral stresses are produced, as the frictionforces on the contact surface of the pipeunder load provide a secure grip.
Because of the slight forces to be absorbed,welding stress can be kept to a minimum,despite the small dimensions of the shearlugs. Generally, they are kept below 35% ofthe yield strength, or creep stress limit forload condition H, according to the permis-sible values in ASME / DIN codes.
Frictional grip with the help of disc springsIf the welding of lugs is not possible for anyfundamental reason, LISEGA offers dynamicpipe clamps fitted with disc springs (fig. 4).Via correspondingly dimensioned sets ofsprings, a lasting torque for permanent frictiongrip can be produced.
In the sphere of dynamicsupports, the design ofpipe clamps is often notcarried out with sufficientcare. In spite of impeccablemain support units (shockabsorbers, rigid struts andenergy absorbers), the functioning of the wholeconstruction can be adver-sely affected by faultypipe clamps.
If no special arrangement is ordered, thebracket connection is so fitted that the mainangulation range runs along the axis of thepipe. For type 37, the weld-on bracket is tobe ordered separately.
3LISEGA standard designTo provide the ideal solution for all areas ofapplication and at the same time achievethe most favorable performance weight ratios, LISEGA offers four standard designs.
Dynamic pipe clamps as hanger clampsThe given permissible loads have been cal-culated for dynamic operation with shockabsorbers / rigid struts in accordance with thedynamic load spectra shown on page 3.10.
In special cases the dynamic clamps are fittedas hanger clamps, under permanent staticload. In this case, the given permissible loadshave to be reduced as per the following table:
Special designsIn some cases, special designs can be a use-ful alternative to pipe clamps types 36 and37. Especially in cases of parallel and angu-lated arrangements, standardized designand calculation methods have proven theirworth.
SelectionThe selection tables are divided according topipe diameters. Via the temperature rangesand the permissible loads, the type designa-tion for the appropriate clamp is found. Afterthat, the installation dimensions are to bechecked using the drawing. Special attentionmust be given to the lug connections of shockabsorbers, energy absorbers or rigid struts.If the standard pin connection d1 does notfit, another appropriate weld-on bracket (seepage 3.8) can be provided.

LISEGA dynamic pipe clamps are suppliedready for installation complete with all thenuts and bolts required.It is recommended that units be stored onlyin closed rooms. If storage in the open isunavoidable, they must be protected fromdirt and moisture.
Prevention of twistingTo prevent the clamp from twisting, it isrecommended that a shear lug be welded to the pipe (see also page 3.19). The lug dimensions can be found in the selection tables for dynamic clamps onpages 3.21 – 3.30.
Type 36This design has a solid upper yoke with inte-grated connection bracket and, depending onthe load range, one or two U-bolts with inlayplate are provided.
For installation, remove the preassembled U-bolts. Then place the yoke over the shearlug. Reassemble the U-bolt and inlay fromthe opposite side, tightening the nuts onlylightly at first. Then check and position theclamp as required. Finally, the nuts can beproperly tightened and countered.
DYNAMIC PIPE CLAMPSINSTALLATION INSTRUCTIONS
Type 37This is the heavier type for larger pipe dia-meters and higher loads. Normally, thebracket type 35 is welded to the upper yoke.If the bracket is supplied loose on customerrequest, it must be welded on site followingthe welding instructions on page 3.16. Thecounterpart to the yoke consists of one ortwo flat steel straps depending on load. Thestraps are pinned to the yoke to make trans-port easier. For installation, the straps mustbe removed from the forked blocks by loo-sening the pin connection. The yoke is placed on the shear lug. From the oppositeside the flat steel strap is fitted into the bolt-on clevises, fixed with the pins and securedby cotter pins. The clamp is then checked andpositioned as required.
Finally the nuts are properly tightened. Thehex nuts must be locked in position by ben-ding the tab washers to prevent uninten-tional loosing.

Short lived but high magnitude fluid transientloads can be compensated by smaller, definedsupport loads. As a result, if energy absor-bers are installed, any reinforcement of exis-ting structures can be dispensed with. In new constructions, the load limitation permits a more economical use of steel rightfrom the start.
Replacement for box frame constructionsEnergy absorbers are ideally suited to theguidance and limitation of thermal move-ments. This way, not only are the usual andoften expensive box frame constructions notrequired, but frictional forces between thepiping and the frame are also avoided.
Pipe whip restraintAn ideal application for energy absorbers isas protection from pipe whip. When used inangular arrangements, large forces can beabsorbed. The direction of defined lines offorce can be determined by the arrangement.The advantage over U-bolt designs consistsin the far less restricted effective radius.
ENERGY ABSORBERTYPE 32
A fully deve-loped concept is
needed for the best pos-sible protection of plant components
against pressure shocks. In the specific useof the most appropriate components, safetyand economic efficiency need not excludeeach other.
Field of applicationThe field of application for LISEGA energyabsorbers lies roughly between the LISEGArigid struts and shock absorbers. Energy ab-sorbers are used just like these components,to suppress abrupt displacements in pipingor other components. In contrast to rigidstruts and shock absorbers, energy absorbersare equipped with an adjustable free stroke(0 - 11/8 inch [0 –30mm] ) allowing slightthermal movements without any resistance.
Conversion into deformation energyAfter passing through the free stroke, possiblepressure shocks are absorbed by limitingstops, and up to a defined load maximum(nominal load) are transferred to the surroun-ding structure. Forces in excess of this orpeaks of force are converted into deformationenergy by the energy absorbers, rather thanloading the other attached components.Piping displacements within the adjusted rangeof the free stroke are acceptable, providedthat the permissible stresses are not therebyexceeded. If necessary, corresponding proofmust be supplied. Special software andadvice can be offered if required.
Maintenance-free useLISEGA energy absorbers are ideal for dealingwith small or negligible thermal movementswhen connected components are to be pro-tected from dynamic overload in a controlledmanner. The energy absorbers contain nowear parts of any kind, and therefore re-quire no maintenance.
Protection from water hammerEnergy absorbers are ideal for protectingother connected components against pos-sible water hammer.
3.33
Energy absorber used instead of a dual guide. The box frame can be dispensed with.
Analysis of piping behaviorWhere energy absorbers are used, the GAPPprogram can be applied to perform seismicand fluid transient analysis. GAPP allowspiping to displace within the permissible tole-rance for the movements. For the load event,the specific load limiting property of energyabsorbers is taken into account. In response spectrum analyses, the programreproduces an equivalent linear spring charac-teristic to approximate to the non-linear situa-tion. When fluid transient analyses are per-formed, the program uses time historymethods.
The unique capacity of the energy absor-ber to take up and convert kinetic energybrings the user valuable benefits:
➜ limitation of dynamic loads for attached components
➜ lighter steel constructions enabled
➜ no need to strengthen auxiliary structures
➜ small installation dimensions minimize danger of interference
➜ thermal piping movement not impeded
➜ no maintenance required due to absence of wear parts
➜ no recurrent testing required
➜ simple installation via length adjustment
Replacement of shock absorbersWhere thermal movements are relatively small,energy absorbers constitute an ideal replace-ment for earlier types of shock absorbers,often prone to failure. In this way, costlyrepairs and recurrent tests are avoided.
Development cooperationThe development of type 32 energy absor-bers is the result of specific and successfulcooperation between SARGENT & LUNDY, aleading American engineering company, andLISEGA.
SARGENT & LUNDY also created the calcula-tion software, or GAPP program. Both thisprog-ram and the energy absorbers themsel-ves have been rigorously tested by theAmerican NRC (Nuclear Reactor Commission),and approved for use in nuclear power stati-ons.

InstallationThe energy absorbers correspond to theload groups in Product Group 3 (dynamiccomponents) and are correspondingly loadand connection compatible with otherconnection components of this productgroup. Attention is drawn to the notices onpages 3.3 and 3.15 to 3.16.
Functional qualificationThe LISEGA energy absorbers have undergonea stringent test program to prove their func-tional reliability. Adequate safety marginshave been proven by numerous dynamicand static loading tests.
3.36
3MODE OF OPERATIONAn energy absorber works via an adjustablefree stroke that absorbs thermal movements.The adjustment of this free stroke can bemade in the range of � 11/8 inch [30 mm] (fora medium sized design). Within this rangethe pipe is free to move without resistance.Dynamic shocks, on the other hand, arelimited in their movement by stops. Theresulting forces are transferred to the surro-unding structures up to the given nominalload, and when above that, are transformedinto deformation energy by the energyabsorber. This has the effect of providing acontrolled protection from overload for theattached components.
The unit consists of an austenitic outer sleeve(A) with a defined undersize, into whichtapered bronze disks (B) have been force fitted. The outer sleeve is closed off with abase plate (C), onto which the connectionlug (D) is attached. Forces are transferredthroughout the whole unit by the stops (E)and the shaft (F).
In the event of a dynamic force exceedingthe insertion force of the tapered disks(nominal load), the disk affected is drivenforward and leads to an expansion of thesleeve. This way, the excess forces are keptclear of the attachment structures via con-version into deformation energy. If such aprocess has occurred, the advance of thetapered disk affected can be read off on theindicator rod (G). For further use of the ener-gy absorber, only a corresponding readjust-ment of the free stroke for the new position

The strut bodies are manufactured in stan-dard lengths. This way, LISEGA rigid strutsare available from stock, TÜV qualificationtested and ASME qualified.
LISEGA rigid struts differ from ordinarydesigns by offering the following advantages:
➜ length adjustable by left hand / right hand threads
➜ no welding
➜ secure locking of joints due to fine threads
➜ favorable performance weight ratios
➜ qualification tested by independentauthority
TasksLISEGA rigid struts type 39 have a numberof important functions for the operationalsafety of piping systems:
➜ Absorption of shocks from unexpected load events. (See page 3.1)
➜ Guidance of pipe systems to control direction of calculated thermal displace-ment direction.
➜ Stabilization of flexible pipe systems by fixing the so-called “zero” positions.
➜ Design of axial stops (“movable” fixed points).
Mode of operation Rigid struts form rigid connections with ballbushings between the piping and structure.No restriction is placed on the limited move-ment of the pipe within the angular displace-ment of the strut. Any movement in the axialdirection of the strut is suppressed.
DesignThe struts consist of a rigid body with a ballbushing joint as a connection at both ends.The structural attachment is formed by a weld-on bracket type 35 (see page 3.8). The con-nection to the piping is formed by the approp-riate dynamic clamp type 36 / 37 (see pages3.21 - 3.30).
The body is made from a tube tapered at theends by forging. The shape corresponds tothe flux of force, and allows a favorable per-formance/ weight ratio. Welding has beencompletely dispensed with. The connectionsare designed as ball bushing joints withturnbuckle function having left hand / righthand threads and enable alength adjustment ina range of
6 or 12inch [150 or
300 mm]. Flat faces areforged on the body to allow a
proper use of wrench and facilitatelength adjustments in the installed condition.Fine threads are used on the ball bushingjoints to ensure secure locking.

PIPE WHIP RESTRAINTS
3.41
Pipe whip restraintsOne speciality in the area of dynamic pipesupports is the pipe whip restraint. Alongsidethe energy absorber type 32, which providesthe optimum solution to this problem, a U-bolt design for specially large loads hasproven to be highly successful.
Pipe whip restraints are exclusively used inthe nuclear industry. They dampen and absorbthe kinetic energy of bursting pipes in emer-gency cases. For this purpose, the elonga-tion capacity of the encompassing U-bolts isused, as they are designed to absorb theexpected dynamic loads.
Pipe whip restraints have safety-related sig-nificance and are subject to the highest de-mands in quality, design and manufacture. As a large scale supplier to the latest gene-ration of nuclear plants, LISEGA has success-fully proven its qualification to supply thisspecific design.

PIPE CLAMPS AND CLAMP BASES,PRODUCT GROUP 4
4.1
StandardizationPipe clamps, clamp bases, pipe weld-on lugsand U-bolts constitute the group of pipe con-nection components. Regarding these pro-ducts, the design criteria for piping systemslead to a wide variation and hence to a particularly large number of components. The dynamic clamps in Product Group 3(see page 3.19) also belong in principle tothis group. The design of both horizontaland vertical piping is determined by
➜ diameters
➜ loads
➜ temperature of the medium
For appropriate coverage of the whole spec-trum with safe products, LISEGA provides acomplete program of standardized productsfor the whole field of application. In linewith the special requirements of the field ofapplication, the corresponding ideal designshape has been developed. Diameters rangefrom OD 0.84 to 36 inch [OD 21.3 to OD914.4], the temperature range extends to
In high temperature pipingsystems, pipe clamps andclamp bases are the mosthighly stressed and there-fore most vulnerable com-ponents in the supportsystem, owing to the add-itional effects of high tem-peratures. In spite of this,pipe clamps are seldomchecked, as access is diffic-ult after commissioningdue to the surroundinginsulation.
1200°F [650°C] and the loads – divided intoeconomical areas of operation – cover the highest level of the practical field of application.

Through standardization of the entire appli-cation spectrum with sophisticated designs,plant designers, constructors and operatorscan draw equal profit:
➜ Comprehensive and clearly structured data tables simplify planning work
➜ all supplies from a single source through integration into a complete support program (LISEGA modular system)
➜ superior quality at competitive prices through rational series production and favorable designs
➜ consistent standardization enables instant availability
➜ favorable performance/weight ratios, easy to install designs and connection compatibility of LISEGA components allow rational installation
➜ the uniform design with guaranteed safety factors ensures maximum operational safety
➜ a correspondingly compact design prevents excessive heat loss
➜ certification from type tests by independent authorities is on hand

These standardized components are an in-tegral part of the LISEGA modular system, soconnection and load compatibility to the loadgroups are correspondingly assured.
QualityBecause of their exposed field of application,the design and construction of the pipe con-nection components require particular at-tention. Just as much care should be spenton the pipe supports as on the piping itself,since:
Piping can never be better than its supports!
The most important prerequisite for depen-dable component quality is general standar-dization.
When purchasing pipe connection compo-nents, confidence should only be placed inproducts of proven suitability.

1. Riser clamp type 45With the riser clamp type 45, the lowerrange suited to this design is covered.
Connection to the vertical piping is made viathe shear lugs welded to the pipe. The designand application of the lugs is the responsib-ility of the piping manufacturer.
Connection to the load chain is made viaconnection pins and LISEGA eye nuts type60. Up to 3 LISEGA load groups can beaccommodated.
When ordering, the desired span (dimension L)is to be given.
Material: carbon steel13CrMo4-5/A387 Gr.12/Gr.22
2. Riser clamp type 46/48The design of this riser clamp exploits the boxshape as the best precondition for the econo-mical use of material. The individual partsare bolted together without weldings viasocket connections.(Patent no. DE3817015)
Connection to the vertically assembled pipingcan be made in two different ways and there-fore demands two different designs:
➜ Type 46 for load support through either 4 or 2 shear lugs welded to the pipe. In general, two lugs come into operation only at ND � 6 inch and are to be so arranged that they lie laterally to the longitudinal axis.
➜ Type 48 for load support through trunnions welded to the pipe.
The bore diameter for the trunnions isapproximately 1/3 of the pipe diameterbased on ASME Code case N-392-3 andDIN EN 13480-3. Connection to the load chain is formed byintegrated lugs designed for connection toLISEGA clevises, type 61.The connection lugs are designed to accom-modate the connection pins for a number ofLISEGA load groups.

➜ For equipping austenitic pipe systems, all pipe clamps can be fitted with austenitic inlay plates.
➜ For special diameters not contained in the selection table, corresponding inter-mediate sizes are available or, for minimaldiameter differences, appropriate inlay plates are supplied.
➜ The riser clamp type 48 can quite easily be supplied as a special design in con-junction with LISEGA rigid struts type 39 as an axial stop for both directions, also for dynamic loads (see “Special Designs”on page 4.7).
4.5
CLAMP BASE TYPE 49
Clamp bases are generally used as slidebearings (loose supports) for horizontally arranged piping systems.
As with pipe clamps, the application spec-trum embraces a diameter range ofOD 0.84 to 36 inch [OD 21.3 to OD914.4mm] and a temperature range up to1110°F [600°C].
Besides the support load, the operationaltemperature of the piping is an essentialdesign criterion in the design of clamp bases.The material to be used is determined bythis. The installation height is governed bythe thickness of the heat insulation.
To keep within a clear level of available sizes,fixed installation heights are assigned to thetemperature ranges.
The fixed installation heights relate, for all diameters, to the respective lower rim of thepipe and have a dimension range of 2 or 4inch [50 or 100mm] increments.
The standard dimensions selected for thesupport height of pipes as well as the lengthof the slide bases cover the most commoncases of application.
Different application conditions through temperature and loading demand differentclamp base designs.
If required, components with special dimen-sions can be supplied (see also “SpecialDesigns”, page 4.7).

41. Design for lower temperatures and smaller pipe diametersThe design for this field of application consistsof two shaped halves. On installation with thepiping, the lower section of both halves isbolted on firmly and provides the slide base.
In the upper section the pipe is secured inposition via a preset screw.
Through the free space under the pipe al-lowed by the design of the component, con-stant ventilation of the area is assured. This is essential for cold piping systems, be-cause otherwise permanent moisture woulddevelop here after only a short time, causingcorrosion of the piping.
Material: A36
2. Design for medium and high temperaturesThis design consists of a shaped lower metalpart firmly welded to two pipe clamps. The lower section is fitted, according to therespective design load, with a reinforcementgosset.
The clamp bases are versatile in application.By the use of two lower sections set againsteach other, a double guide can easily be prod-uced. By the additional application of lateralguides, a manifold guiding system can beprovided. The shape of the support platepermits the simple mounting of lift-offrestraints. The lower section is so designedthat it can be equipped with a stainless steelplate as a sliding surface for a PTFE bearing.

3. Special designs
➜ For the support of austenitic piping systems,all clamp bases can be fitted with corresponding stainless steel inlay plates.
➜ Special lengths or heights are possible if required. In cases of great expansion it might be more expedient to arrange for correspondingly long support surfaceson site.
➜ The slide bearings of all clamp bases can be supplied as sliding surfaces for a PTFE or graphite bearing.
➜ For special diameters not contained in theselection table, corresponding intermediatesizes are supplied. For minimal diameter differences suitable inlay plates areprovided.
➜ The clamp bases can if required be fitted with lift-off restraints.
➜ Two-fold or manifold guidings using standard clamp bases can be supplied if required (see “Special Designs” on page 4.7).

SPECIAL DESIGNS
Special designsAlthough the standardized LISEGA range ofpipe surrounding support components is comprehensive and covers all common areasof application, more complicated casessometimes arise where only a special solu-tion can solve the problem.
Among other cases, special designs are mostoften required especially for the followingspecific applications:
➜ exceptionally restricted areas
➜ interferences insurmountable by common techniques
➜ tailor-made fixed point designs
➜ exceptionally high load requirements
➜ especially high temperatures (up to 1800°F)
➜ abnormal insulation thicknesses
➜ irregularly inclining pipes
➜ special trunnion diameters
LISEGA’s customers are not left on their ownin this regard. For such particular assignmentsan experienced team of technicians andengineers is available, ready to react speedilyand flexibly with appropriate solutions. Theyare supported by a kit of special tools suchas modern CAD programs and individual in-house calculation software. In addition tothis, a broad repertoire of well proven basicdesigns is on hand.
Every problem has a solution – this convic-tion motivates LISEGA’s experts in supporttechnology. For our clients this can bedemonstrated as required at any time!
The use of standard com-ponents in the field of pipesupports has long sinceproven its superiority, lea-ding to enormous savingsin time and costs associ-ated with engineering, deli-very and installation. This especially includespipe clamps and clampbases.
However, because of anextremely wide range ofapplications and the complexity of piping, insome cases special designsare required. In such situations it is important tohave experts on hand toensure tried and testedsolutions and to profit fromproven calculation proce-dures.

The selection tables on the following pagesoffer a general view of the fields of applic-ation. They have been arranged in ascendingorder according to pipe diameters. All pipeclamps and clamp bases to be considered fora given design of pipe system can thereforebe found clearly set out on one page.
The following points are important for appli-cation purposes:
1. In the selection table, all the informationcan be found that is required for determiningthe correct component and placing an orderfree of uncertainty.
2. The component with the lowest permissibleload to cover in the appropriate temperaturerange is at the same time the most econo-mical of all those listed.
3. The geometrical values of the connectionsare compatible with those of LISEGA connec-tion components. Via the wide load appli-cation range, connections in various LISEGAload groups can be linked up.
4. The lengths of connection lugs are so de-signed that the connection points lie outsidethe economical insulation thicknesses.
5. For use in pipe systems made of austeniticmaterial, all pipe clamps and clamp bases canbe equipped with corresponding inlay plates.
6. In selecting an appropriate pipe clamp, thefollowing procedure should be followed:
6.1 Determination of the correct page for theexternal dimensions (OD) of the piping to besupported.
6.2 Determination of the correct temperaturerange in the column for the desired supporttype, horizontal or vertical.
6.3 Determination of the permissible load tobe covered.
6.4 Checking of the installation dimension E and width B for agreement with the installation conditions prevailing.
6.5 For riser clamps, checking of the span(L-dimension).
6.6 For riser clamps of Type 46/48, the de-cision as to whether shear lugs or trunnionsshould be used.
6.7 On the basis of the properly fitting LISEGAload group ranges provided, the conformityof the connection with the load chain requi-red can be ascertained.
6.8 Determination of the selected componentthrough specification of the appropriateLISEGA type designation.
7.0 In selecting a suitable clamp base, pro-ceed according to points 6.1 – 6.3.
In addition, attention should be paid to thechoice of the correct height (dimension H)which is determined by the thickness of theheat insulation.
7.1 The heights given (dimension H) as wellas the lengths (dimension A) are standarddimensions and cover the most commonapplication cases. If required, componentsof different dimensions can be supplied.
8. The supply of pipe clamps and clamp basesis possible as special designs for particularuses and conditions (see pages 4.4 and 4.6in this regard).
9. In the design and construction of LISEGApipe clamps and clamp bases, nuclear ap-plications have also been considered.However, separate fabrication is required inthis case with strict adherence to the LISEGAquality management system. The type desig-nation hereby differs in the 5th digit by ad-dition of a 5 (see also page 0.7 in this respect).

INSTALLATION INSTRUCTIONS
LISEGA pipe clamps and clamp bases aresupplied ready for use complete with all bol-ting required. The standard surface treatmentis outlined in Technical Specifications, page0.11.
For safe operation and rational installationthe following points should be observed.
If stored in the open, components should beprotected from dirt and water.
Horizontal clamp type 42This pipe clamp is used as a horizontal clampwith eye nut type 60. When tightening bol-ting it must be ensured that the halves areparallel to each other. Counter nuts are tobe used.
Horizontal clamp type 43With this horizontal clamp, connection ismade via a separate connecting pin, with eyenut type 60. It has to be made sure that thepin is secured by the cotter pin provided.Otherwise, proceed as with type 42.
Horizontal clamp type 44, U-bolt/strapThese horizontal clamps consist of an upperpart with connecting lug and, depending onload or temperature range, of a U-bolt withan inlay plate or strap as lower part. Forinstallation, the preassembled lower part istaken off by loosening the fastening nuts orremoving the connecting pins. The upperpart is seated on top of the pipe and thelower part fitted by screwing the U-bolt on orpinning the flat steel strap on. After adjustingthe clamp, the connections are tightened.The U-bolts are secured by counter nuts andthe flat steel straps by tab washers for thehexagon nuts.
Pipe clamp type 44, over 1110°F [600°C]These clamps consist of a yoke with connec-ting lug and restraint, as well as a flat steelstrap for the lower part. To install, therestraint and strap are taken off by removingthe outer threaded rods and connectingbolts. The upper part is then fitted into the hanger.The restraint and strap are fitted again, bol-ted on, and the threaded rods mounted. All parts are to be checked for secure fit.

The bolting has to be tigh-tened and secured by counter nuts.The clamp is mounted via the other suppor-ting pins, which are secured by washers andcotter pins. The clamp is to be adjusted tothe height indicated by tightening the sup-porting boltings so that it is form fitted forload actuation onto the shear lugs.
Riser clamp type 46This clamp is supplied loose, sealed in plasticfoil.
For installation we recommend hanging thefront plates � in the supports first. The partsto be tightened should be set at their lowestlevel. Afterwards both side plates � can beinserted in the intake slot. With heavyclamps, the other side should be moment-arily supported. Then the top plates � forthe shear lugs can be fitted and bolted onby adjusting and tightening the preassemb-led securing plates �. By tightening the hanging parts the clamp isto be adjusted to the height indicated andform fitted for load actuation onto the shearlugs.

For heavy clamps, support with woodenblocks or ropes is required.
The front plates � are now fitted into theintake slots and connected to the hangingparts. Secure connection of the front andside plates is made by adjusting and tigh-tening the preassembled securing plates �.By tightening the supports the clamp is tobe adjusted to the height indicated andform fitted for load actuation to the trun-nions.
Clamp bases type 49LISEGA clamp bases are sliding supports,connected to the pipe by clamping tension.During installation it is essential that thebase plate lies flush and can glide unob-structed over the given stretches.
If required, the base plate may be weldedto the supporting surface.
According to the particular field of applica-tion, different designs are used with regardto support height, pipe diameter, support loadand operating temperature. The followingpoints are hereby to be observed:
Type 49 .. .1 and 49 .. .2This clamp base consists of two halves to befitted to each side of the pipes. The cornered
ends form the base plate. In the lowerpart, both halves are firmly connected to
each other by bolting. Through clampingtension, the upper bolting secures theclamp base against slipping.
Type 49 .. .3 and 49 .. .5The foot of this clamp base forms a solidsupport into which the pipe can be fitted.The upper part, providing clamping tension,consists of half a clamp and is to be securelybolted.

ROLLER BEARINGSTYPE 51 TO 53
LISEGA – Standard Roller Bearings & Pipe SaddlesThese items are standardized in LISEGAProduct Group 5 for a wide range of applic-ations.
For applications outside the standard range,special designs can be offered.
Specification and design of roller bearingsIn the design of standard components, prac-tical requirements find special consideration.
The standard roller bearing is hot-dip galvan-ized and provides optimum corrosion protec-tion. Except for the movable double cylinderroller bearing Type 53 .. 29, weldings havebeen dispensed with.
The bearing axles are made from austeniticmaterial and have a polished surface. The slide bearings incorporate bushings madefrom a Teflon bronze sintered compound mat-erial fitted into the roller. The bearings aremaintenance free and guarantee dry runningqualities. The formed shoulder of each bushingminimizes the stick-slip drag effect on lateralloading. The bearing axles are permanentlyfixed in the middle section of the base. Spec-ial locking on the side bracket is not required.
The rollers are made from high tensile carbonsteel. Their outer surfaces are machined.
To compensate for misaligned anchor bolts,on site, the base holes are slotted for addi-tional adjustment.
The height dimensions (E) within a load grouprange are identical for all roller bearings, inc-luding the lateral movement type.
Information regarding material codes, stan-dards, calculations and weldings are givenin the Technical Specification on page 0.9and 0.10
Manufacture and StoringFor frequently used items, efficient serial prod-uction and stocking can be achieved throughstandardization.
Modern order logistics is possible through asingle fabrication process or in small lots,thus ensuring short fabrication and deliverytimes.
Technical Data for Roller Bearings
➜ rolling resistance of the rollers max 4%
➜ rolling resistance on lateral movement max 4%
➜ temperature range at nominal load -22°F to 176°F [-30°C to 80°C]
➜ permissible lateral loading 35% of nominal load
➜ permissible lift-off load 10% of nominal load
Piping systems arrangedhorizontally over longstretches are placed onsupports. To allow normalthermal movement, thesupport points are designedas either sliding or rollertypes.
For larger diameter pipingand especially when fluidsand insulation produce highloads, roller bearings prov-ide the optimum solution.

INSTALLATION INSTRUCTIONS
Roller BearingsThe roller bearings can be fixed by simplebolt connections or welded to the contactsurface of the pipe support. In each case thecomplete width of the base plate must besupported and secured.
Due to the slotted holes, roller bearings caneasily be adjusted even with slightly misal-igned anchor bolts.
Pipe SaddlesWelded pipe saddles are supplied coated witha weldable primer (1.18 mil [30µm]) (seeTechnical Specification page 0.10).
Care must be taken that the specified min-imum weld size is applied.
Pipe saddles with clamps are supplied readyto install.
Care must be taken to ensure the correct pos-itioning and adequate presetting of the bolts.
Lift-off restraintsWhen installing the lift-off restraint plate, caremust be taken to ensure that the gap bet-ween plate and roller is sufficient for normalmovement along the whole travel range.

INSULATED PIPE SUPPORTSTYPE 56
5.7
Pipe Supports for Cryogenic ApplicationsLISEGA offer a complete range of insulatedpipe supports for all types of cryogenic pipingapplications. Typically, these include industrialprocesses involving the production, transpor-tation and distribution of liquefied gasesincluding methane, propane, butane (LNG),ethylene, oxygen, nitrogen and ammonia (LPG).
LISEGA standard insulated pipe supports aredesigned in accordance with recognized engin-eering specifications and international stan-dards for pipes ranging in size from OD 0.84inch [21.3mm] to OD 36 inch [914mm] withinsulation thicknesses from 1 inch [25mm]up to 10 inch [250mm]. The supports aremanufactured using materials suitable forthe loads specified and for temperaturesranging from ambient to –321°F [–196°C].
Insulation Material
The insulation material that forms an integralpart of the insulated pipe support assemblyis manufactured using fire-retarding high-density polyurethane (PUF) foam. For thesupply of the PUF components and consu-mables, LISEGA have formed an alliance with Bains HardingIndustries Pty. Ltd., Australia. With more thantwenty five years experience in industrialinsulation, the company has extensive experience in the manufacture of rigid polyurethane insulation materials includinghighdensity moulded products and provideconstruction and maintenance services tothe liquefied natural gas industry (LNG) inAustralia and South East Asia.
PUF ManufactureThe PUF is monolithically molded in heavyduty steel molds under carefully controlledtemperature and humidity conditions. Thisensures compliance with dimensional spec-ifications and provides clean, sharp edgesthat fit neatly with the adjacent line insul-ation material on site. Careful attention isgiven to the curing of the PUF after moldingto ensure dimensional stability.
Both single and multilayer PUF cradlesystems are manufactured in accordancewith ASTM C-585 and incorporate steppedradial and offset longitudinal joints. This pro-vides a reliable interlocking interface witheach layer of the adjacent line insulation onsite and prevents a direct vapor path to theinsulation surface.
All exposed PUF cradle surfaces are sealedwith cryogenic fire-retarding elastomeric vaporbarrier mastic to prevent moisture ingress.A laminated aluminum/polyester foil is bon-ded to the outermost surface of the PUFcradle assembly. This has an overlap allo-wance designed to cover the adjacent lineinsulation material on site. Finally, a sheetmetal jacket forms part of the PUF cradleassembly and fits over the aluminum/poly-ester foil to provide additional support andinsulation protection.
The PUF cradles are available in three stan-dard densities toprovide for varyingload requirements – 10 lbs/ft3 [160 kg/m3], 14 lbs/ft3 [224 kg/m3], 20 lbs/ft3 [320 kg/m3].

Pipe Supports for Cryogenic ApplicationsLISEGA standard cold block supports are de-signed in accordance with recognized engin-eering specifications and international stand-ards for pipes ranging in size from OD 0.84inch [21.3mm] to OD 36 inch [914mm]. Thesupports are manufactured using materialsthat are suitable for the loads specified andtemperatures ranging from ambient to–321°F [–196°C].
Cold Block MaterialThe cold block insulation material formingan integral part of the cold block pipe supportassembly is designed to provide a sufficientthermal insulation barrier between the pipeoperating at subzero temperatures and thesupporting structure that is at ambient tem-perature.
LISEGA standard cold block supports incor-porate Lignostone® densified wood blocksthat are manufactured from selected beechveneers, impregnated under vacuum withthermosetting synthetic resin and densifiedunder heat and pressure. The Lignostone®
blocks combine high strength with low ther-mal conductivity, have proven cryogeniccapability and are used exclusively for coldpipe applications throughout the world.
Alternative cold block insulation materialssuitable for cryogenic applications are avail-able on request.

LISEGA connecting components offer special advantages:
➜ universal application
➜ load and connection compatibility with the LISEGA modular system
➜ drop forged and heat treated
➜ standard electrogalvanized or if required, hot dip galvanized finish
➜ qualification by special type testing
ROD CONNECTING ELEMENTSTYPE 60 TO 64
The components in Product Group 6 arespecially designed threaded elements forconnecting the attachment rods to othersupport components. In the load chains,they connect components that in part havedifferently designed connections such aslugs, clevises or eye nuts.
The connecting parts in Product Group 6form an independent group within themodular system and have been speciallydesigned for optimum suitability as pipesupport components.
The components are drop forged, and de-signed (apart from turnbuckles type 62) toallow slight length adjustments, despitetheir limited installation height.
The permissible loads correspond with theload table for statically determined pipesupports on page 0.5 of the Technical Specifications.
Eye nut Type 60 is used to join the rod to apin connection, the clevis Type 61 to join itto a lug connection.
Turnbuckle Type 62 is supplied with a right-hand thread at one end and a left-hand thread at the other. It is used togetherwith the tie rod Type 65 to provide lengthadjustment and presetting of the load chains.
Coupling Type 64 is used to produce rodlengths greater than 12 feet [3.65m].
All threads (except in turnbuckles Type 62)are right-hand and available in metric or UNCstandard.
For corrosion protection, all components aresupplied complete with a standard electro-galvanized finish (zinc thickness approx. 0.59 mil [15�m], yellow chromatized formetric and white for UNC threads). For use inparticularly aggressive environments, thecomponents can be supplied with a hot dipgalvanized finish.
Material certification can be supplied for allcomponents if required.

constant hanger. The longer one is the fit-ting length and can be cut on site accordingto installation length.
Standard lengthsIn general, larger tolerance ranges in thebuilding structure of plants frequently leadto problems when lengths cut to measurefor the connecting rods are used; they oftenprove to be too short. Offering more flexibilityin application, connecting rods in standardlengths have come into increasing use.Fitting can be simply carried out with hang-ing rods already mounted at the upper end.Awkward measurement involving the risk oferrors is thereby avoided. Structural toleran-ces can be favorably compensated.
Length adjustmentTie rods type 65 with left/right hand threadsare always used together with turnbuckletype 62 and form standard lengths. They aredesigned for length adjustment and load-actuated presetting of load chains. All otherthread connections are exclusively right-hand and have to be locked using hexagonnut type 63.
Corrosion protectionAll rods are electrogalvanized as standard(coat thickness 0.59mil [15µm], chromatizedyellow for metric and white for UNC standards).Hot dip galvanizing is available on request.
CertificationMaterial certification can be supplied for allcomponents on request.
Piping systems are embedded in load chainswhere connecting rods form an indispensablecomponent. When selecting them, specialattention must be paid to quality to preventthese seemingly simple units from becom-ing the weakest link in the chain. Decisivefactors for their loading capacity are, besideadequate dimensions, material quality anddesign.
ApplicationsThreaded rods and tie rods connect supportcomponents to each other to bridge instal-lation heights. In conjunction with connec-ting components they can be used as rigidsupports, and in elastic load chains can beused with spring and constant hangers.
Materials and loadingsFor the attachment rods, only materials withguaranteed mechanical properties, with goodhomogeneity and sufficient cold ductility areused. The permissible loads correspond tothe load sufficient table for statically definedcomponents (see Technical specificationspage 0.5).
Rolled threadsAll threads are manufactured using a rollingprocess. Thread rolling does not sever mil-ling fibres as in thread cutting. By means ofthis thread rolling process the material ismade to flow and thereby plastically formed.In this way, additional strengthening of thesurface is achieved, free of notches and offering high surface quality.
In this way, frictional resistance is reduced, with a favorable effect on theadjustment of the rods under loading. In addition, additional reserves for thebending and tensile strength propertiesresult from this by comparison with thedesign calculations.
TypesFully threaded rods type 67 up to 2 UNCand tie rods type 66 (from 3/4 UNC) are avail-able in 24 inch length increments from 24inch up to 12 feet. Tie rods are threaded 12inch at one end and 24 inch at the other. The shorter thread is for adjustment and,for example, for connection to a variable or

STRUCTURAL ATTACHMENTS, TRAPEZESPRODUCT GROUP 7
Product Group 7As well as trapezes, the components ofProduct Group 7 include attachment elementsconnecting directly to the structure, such astrapezes.
The permissible loads correspond with theload table for statically determined compo-nents on page 0.5 of the TechnicalSpecification.
For weld-on clevis type 73 and weld-on eyeplate type 75, the minimum weld thicknessesmust be considered. These are designed insuch a way that the maximum weld stressesdo not exceed 10.9ksi [75N/mm2] duringnormal operating conditions.
The stress analysis is based on a loadapplied conically at under 6° angulation.
The weld-on clevis type 73 is particularlysuited for attachment to hollow sections.
The beam clamp type 78 is designed forunwelded on site attachment. The beamwidth is to be specified when ordering.
Trapeze types 79 are suitable for use withclamp base type 49 and can be used asrigid hangers or in conjunction with variableand constant hangers.
For protection against corrosion, the com-ponents are coated with a weldable primer(1.18mil [30µm] ) or electrogalvanized andthen yellow chromatized (zinc thickness0.59mil [15µm] ). The trapeze sections arecoated to the LISEGA standard.
Material certification can be supplied for allcomponents on request.
Standardized connecting parts
The attachment of pipesupports to the load bear-ing structure is producedby means of special com-ponents to be welded orclamped. The safety of theconnections depends ontheir adaptation to the prevailing situation andtheir particular suitabilityin each case.

BEAM ADAPTER TYPE 76
For alterations or extensions to pipe systems or structural steel in existing plants, clamp connec-tions are often preferred to wel-ding for the necessary attachmentto the existing structure of pipe supports or additional steel. The use of this method is obligatory when welding is ruled out for safety reasons.The long-lasting security of this type of connection depends essen-tially on the condition of the contactsurfaces and the preset forces applied. For a reliable connection, the specific design of the clamp elements used is decisive.
Offering the utmost reliability, LISEGA beamadapters type 76 serve as secure connectionsfor this purpose.
These newly developed components enablethe attachment of diverse components toexisting steel without welding or drilling,while installation is simple and time-saving.LISEGA beam adapters adjust automaticallyon tightening to the thickness of the compo-nent to be clamped. If the given torquevalues are observed, the lasting security ofthe connection is guaranteed. Existing corro-sion protection, e.g. hot-dip galvanizing orcolor coating, is not impaired.

The intelligent solution for support planningLISEGA’s unique modular system was theprerequisite for the creation of highly sophis-ticated user software. The solutions on handopen up new opportunities for increasedengineering design efficiency, improved qualityand significant savings in project manhours.
The general introduction of 2D and 3D CADmodelling has already had a dramatic effecton the design process for pipework systems.However, the benefits for pipe support designhave been limited because supports were notincluded in the 3D CAD programs.
The LICAD® program has set new standards inthis field. It allows the generation of pipe sup-port drawings, bills of materials and 3-Dmodels in minutes rather than hours. LICAD isan intelligent front-end program that providesall the required interface data for all commonCAD software programs from a single source.From the point of view of quality this singlesource function cannot be overemphasised. To exploit further fields of application for

8SOFTWARE WITH PROFIT EFFECT
Needed first - designed lastAs a rule, the planning and design of com-plex pipe systems runs through numerousphases of optimization. Inevitably, the designof pipe supports takes place at the end ofthe whole process, and therefore oftencomes too late to ensure prompt delivery.Although the supports are needed on sitebeforehand in order to ensure optimuminstallation of the piping, they lie right atthe end of the planning chain.
At this point, it is even more vital to avoidunnecessary delay. The time factor is now allimportant.
LICAD speeds up the planning processLICAD, the unique LISEGA design programfor pipe supports, sets the highest standardsin efficiency. With LICAD, poring over catalogsand the painstaking preparation of bills ofmaterial can be dispensed with. The designof supports and load chains no longer needsto be configured manually and then drawnup at great expense in time and money.What otherwise takes hours to produce canbe done in minutes electronically - at theclick of a mouse!
Future orientated logisticsVia LICAD, savings in time are possible in the logistics process from planning rightthrough to delivery. For example, if requiredthe LICAD data can be sent directly by acustomer to our main computer system for order processing on thesame day. This fits in well with ever tighterorder schedules!

LICAD is simple to useThe relevant data for individual supportpoints is entered using a menu driven prog-ram control. Only 6 parameters are requiredin order to find the optimum solution.
➜ pipe diameter➜ temperature of the medium➜ operating load➜ travel➜ installation height➜ support configuration
From this input, the appropriate load chainsare created automatically and in fractions ofa second. The optimum selection of variablespring and constant hangers is made by theprogram simultaneously. Specific customerrequirements, such as travel and load reservesin accordance with ASME, B 31.3, VGB or othercodes, are taken into account. This is provi-ded for by the corresponding input in a spe-cial menu. Considering these requirements,the programmed algorithm always ensuresthat the most economical solution will beselected from the possible options.
True to scale drawingsThe support chains created are automaticallysaved as complete assemblies and can beprinted or plotted as a drawing at any time.They are true to scale and contain all relevant details, including parts lists withweights and material, and if required, pricingand location plan.
LISEGA modular system forms the basisA database system forms the basis of theprogram which the complete LISEGA productrange is incorporated into as a functionalmodular system. From more than 8000 stan-dard items, compatible herein with regard toloads and connections, more than 100 stan-dard configurations cover practically anyinstallation situation.

Interference checksFor larger plant projects, the design of thebuilding structure, including steelwork, maincomponents and piping, is carried out via3D CAD programs, such as PDS/Microstation(Intergraph), Plant Space (Bentley) or PDMS(CADCENTRE). Planning continuity, as well asthe need to consider possible interferences,necessitate the inclusion of the pipe sup-ports in the process. Using defined interfaces,LICAD support designs can be transferredwith no additional effort three-dimensionallyand true to scale into the leading CAD programs . The standard LICAD drawings are automaticallytransposed into 3D using special data files.
LICAD saves up to 50% of planning costsLICAD runs smoothly on any modern PC withWindows and is easy to use. Due to its parti-cular effectiveness, LICAD has already becomean indispensable tool for numerous enginee-ring departments when designing supports.Potential cost savings of up to 50% simplycannot be ignored!
Auxiliary steelworkLICAD creates ready to install load chains from standard supports, from the buildingconnection right through to the pipe-surrounding attachment. In order to producethe connection to the existing structure,supplementary auxiliary structures are fre-quently required. Via a special interface, the appropriate LICADdesigns are transferred to a separate CADprogram (e.g. AutoCAD), where they can besupplemented as desired. In most cases,where designs are not to complicated, EASYSTEEL (see page 8.5) offers the idealsolution.

Concept sketch
The ideal task when design-ing pipe supports is to con-nect a pipe directly to theexisting plant structure. However, due to the givensupport positions, in mostcases the existing plantstructure does not allow asuitable connenction. Thesupport designer is thenrequired to plan additionalsecondary steel, so-calledauxiliary structures.
Standard supportsWith LICAD, the most appropriate supportconfigurations in each case are determined,then the corresponding standard supports inall their individual elements selected. A sup-port drawing, parts list and 3D model can allbe automatically generated using thissystem. If the standard supports cannot beconnected directly to the existing plant struc-ture, the next step is to use additional steelelements for the necessary adaptation.
Planning secondary steelAlthough this steel may consist of only 1 or2 items, each design is invariably unique, itsmanufacture being both labour-intensive andcostly using traditional techniques.Creating the design and producing a drawingand a bill of materials with the cut lengthsand economic load calculations requires asignificant amount of time, even for simpledesigns.
With EASYSTEEL, LISEGA has now developeda powerful tool to reduce this time to a mini-mum and improve the quality of the designprocess. At the same time it ensures interfacecompatibility for electronic integration. Thenew LISEGA EASYSTEEL design program is alogical complement to the LISEGA modularsystem and the LICAD program.
The program can be used either indepen-dently or in conjunction with data importedfrom a LICAD file. The user is guided menu-controlled through the design process, usingeasy selection screens.
EASYSTEEL provides the user with the mostfrequently used forms of steel designs asbasic elements. The most common connec-tion types are also supplied. The user selectsthe appropriate design shape from the cor-responding selection screens and puts inthe relevant dimensions and interface data.The program then suggests beam sizes thatare compatible in dimension and loadingwith the LISEGA attachment component. Afurther feature is the possibility of adaptationto the surrounding structure.After the user has decided on the preferredsection size, the program generates a trueto scale drawing with bill of materials andcut list.
For the design elements available, EASY-STEEL contains a series of load capacitydata bases. The information needed for thedesign-related selection of frame elementsregarding weld sizes or bolt dimensions canbe found here.

Beam systemsThe program allows the selection of beamarrangements most commonly used forsecondary steel designs as standard:
➜ beam between two existing structures
➜ cantilever types
➜ post types
Loading of beams is possible from above or below.
Section sizesThe program uses virtual section sizes andcovers a sufficiently wide range of commonlyused beam sections for various countries.
The list of programed beam sections consi-ders American, European, Japanese andChinese standards. After determination of arange of suitable steel sizes the designer candecide which national standards shall beused to generate the drawings.
Due to the modular program, and the use ofvirtual section sizes, further specific nationalstandards can be included.
This system allows the flexibility to design independently of specific nationalstandards.

Options of steel attachment
Attachment to existing structureThe most common techniques for attachment to the existing structure are available in theprogram:
➜ beam directly welded
➜ beam with shim plates or beam with end-plate to spread the load
➜ beam with bolt-on plates
➜ welded clip-angle connections
➜ cut-out flange connection to fit inbetween two beams (with or without end/shim plate)
➜ beam end support on or under a roof girder.
Weld sizes The weld sizes selected by the program areload compatible with the LISEGA modularsystem whether the weld is measured inthroat thickness (mm) or leg length (inch,acc. to American standard).
Connection compatibilityGeometric checks are performed to avoiddesigns which would not fit when assembledon site. These checks include:
1. for welded attachments:
➜ comparison of the width of the attachment(incl. weld seam) with beam width
➜ determination of the weld size suitable for the section and attachment according to prevailing rules and recommendations
2. for bolted connections:
➜ selection of section sizes that allow com-patibility of bolt holes with each other
8.9
How the program worksThe program is database driven, working withload capacity tables to determine the correctsection, bolting and weld sizes. The conceptallows the addition of other national sectionstandards.
Codes and regulationsThe permissible load values used to selectbeam and weld sizes are based on commonlyrecognized steelwork codes such as AISC, BS,DIN. Additionally, user specifications can bedefined and considered during the selectionprocess.
USE OF THE PROGRAM
User inputThe program requires the following inputs:
➜ type designation of the attachment part
➜ operating load acting on the beam
➜ notation of the connection point
This input can be taken directly from theLICAD file.
Four continuous screens guide the user indefining:
➜ positioning of the attachment
➜ the beam system
➜ the necessary length information
➜ the type of connection to surrounding structure
The scaled drawing includes all dimensionsand the bill of material. The weld sizes areshown according to requirements in throatthickness (mm) or leg length (inch). The lan-guage desired can be selected from a rangeof the most common languages.
All relevant data can be entered in one step

ENGINEERING, SUPPORT DESIGN
9.8 Engineering, support designBesides high quality requirements, it isessential in the planning of supports tokeep to tight schedules and economic tar-gets. At the same time, plant operatorskeep a consciously tight rein on the resour-ces required. To avoid thereby endangeringthe budgeting and logistics of entire projects,the planning arrangements are placed in thehands of suitable engineering firms (out-sourcing).
LISEGA has been a specialist for a long peri-od in the provision of the relevant facilitiesfor the execution of complex planning activi-ties. Highly qualified and experienced techni-cians and engineers are available at all LISEGAlocations. For the optimum fulfilment of all customer requirements, the differentareas are equipped with the latest, most
sophisticated software. In internationallyoverlapping projects, and whenever required,the engineering sections at the various loca-tions work in close association.
Pipe supports for complete plant systemsincluding secondary steel are conceived,planned and drawn up according to projectrequirements. On the basis of the LISEGAmodular system and decades of experience,ready-to-install load chains from structuralattachment right through to pipe-surroundingcomponent are generated from stan-dard supports. The relevant internationaltechnical codes and standards as well asparticular customer requirements are thereby

Engineering in Zeven, Germany
systematically considered. For the designand dimensioning of both supports andsecondary steel, the relevant pipe systemcalculation data as well as detailed plansof the piping layout and structural factorsare taken into account.
For the effective transfer of the supportarrangements into 2D or 3D models, and toguarantee the economical preparation ofdrawings, the most sophisticated software isapplied. In addition to our own speciallydeveloped material the following standardprograms are currently in use:
➜ LICAD
➜ AutoCAD (2D-CAD)
➜ MicroStation (2D and 3D-CAD)
➜ PDMS (3D-CAD)
➜ Staad III (static / dynamic calculation of secondary steel)
➜ PSA 5 (pipe system calculation program)
➜ CAE-pipe (pipe system calculation program)
Analysis of complex support arrangements
The proper functional inte-gration of pipe supportsinto the existing pipingand plant concept has adecisive influence on thelong-term behavior of pipesystems. The same careand attention should there-fore be paid to supportplanning as to the pipesystems themselves. Inthis respect, the choice ofproduct and the availabilityof up-to-date design soft-ware has a major effect onthe quality of planning.

LICAD drawing
CAD drawing according to customer requirements
The following engineering services are avai-lable according to requirements:
9.8.1 Design of support arrangements (loadchain designs) with LICAD:
The following data should ideally be sup-plied by the customer:
➜ pipe diameter
➜ loads
➜ movements
➜ temperatures
➜ insulation thickness, if necessary
➜ piping material
➜ installation length and position, orcorresponding piping and structural plans
➜ specifications
On the basis of these data, ready-to-installload chains are generated with the LISEGAdesign program LICAD from standard sup-ports, from structural attachment right throughto pipe-surrounding component. The designsso prepared are stored and printed out asscale drawings, including parts lists with loadand material data. As an option, locationplans and pricing details can be included withthe LICAD drawings.
9.8.2 Generation of 2D CAD drawings with-out supplementary steel
For the preparation of 2D CAD drawings thefollowing information on the drawing layout,in addition to the details in 9.8.1, is required:
➜ drawing sheet in format DXF, DWG or DGN
➜ drawing numbers
➜ location plans
As the basis for the CAD drawing, a LICADsupport configuration together with dimensio-ning, parts list and relevant adjustment datais supplied via a special interface. The drawingsheet required is inserted in the customer's
specific drawing layout. The CAD drawing is supplemented by a location plan and drawingnumber.
9.7
9.8.3 Generation of 2D CAD drawings incl.supplementary steel
As well as customer details mentioned in9.8.1 and 9.8.2, data as to dimension andposition of the steelwork is required for CADdrawings including supplementary steel(secondary steel). The CAD drawings aregenerated as in 9.8.2 but additionally sup-plemented by the steelwork required.
9.8.4 Complete planning with preparation ofCAD drawingsFor complete support planning (engineering),the following documentation is supplied bythe customer beside the data according to9.8.1:
➜ drawing sheet in format DXF, DWG or DGN
➜ drawing numbers
➜ piping isometrics
➜ piping calculations
➜ pipe plans
➜ structural plans
The planning of the support designs and thesecondary steel required is based on thedocumentation supplied. The results aregenerated as 2D CAD drawings in the AutoCAD program as described in 9.8.2 and 9.8.3.
9.8.5 Preparation of 3D models withMicroStation for PDSFor the generation of 3D models onMicroStation the pipe supports are first pre-pared as 2D models. The 2D data are thentransposed into 3D data by LICAD andtransferred via an interface into theMicroStation 3D model. The secondary steelrequired is supplemented in the 3D model.In PDS the 3D models so generated can beused for interference checks.

9.8.6 Support design of 3D models inPDMSFor the design of 3D pipe system supportsin the PDMS program, the customer makesa PDMS model complete with pipe systems,steel and all structural components available.In addition, the data listed in 9.8.1 is required for the design of pipe supports.The support points, including the necessarysecondary steel, are planned and laid outdirectly in the PDMS 3D model by experien-ced designers. LICAD provides the well-triedbasis for this. The load chains generated inLICAD, transposed into 3D data, are integra-ted into the model with the aid of a PDMSinterface. Any secondary steel required canbe directly supplemented in PDMS.
Finally, an examination of possible obstructions(interference check) is carried out in the 3Dmodel. The customer receives a complete,fully checked 3D model with all plannedsupport positions and the relevant 2D draw-
ings, including parts lists. The support draw-ings can also be generated in the 3D modeif required.

9.8.8 Pipe system calculation In older installations it is often necessary forreasons of operational safety to renew pipesystems and supports in order to meet cur-rent standards in technology. There is ofteninsufficient documentation available offeringinformation on calculations regarding theoriginal design. If so desired, a static calcu-lation of pipe systems can be provided. Thefollowing typical load conditions per supportpoint are calculated:
➜ weight
➜ temperature
➜ static G
➜ emergency shutdown
➜ hydrostatic test
The codes ASME B31.1, ASME B31.3 andBS806 are observed for the calculations. Therelevant code is to be defined on orderingaccording to version and year.

ON SITE SERVICE
9.9 Plant serviceAdditional stress and strain caused by low-quality pipe supports during pipe systemoperation can lead to long-term damagethat considerably increases the risk of mal-function and breakdown when the plant isin operation.
Faults frequently occurring in pipe supportsare:
➜ poor support designs
➜ faulty installation
➜ incorrect load settings
➜ inappropriate instructions
➜ deficient quality of support components
A particular problem often arises in olderinstallations when variable spring and con-stant hangers are installed with springs thatare not pre-relaxed (see page 1.16 in thisrespect). Through the increasing relaxationover a period of time a growing loss of ulti-mate load gradually occurs. Load deviationsresulting from this can lead to impermissibleadditional stress in sensitive areas, e.g. atconnection points. Timely inspection in theplant can contribute to the prompt identifi-cation and elimination of critical stresses.
The operational safety ofpipe systems and thereforethe availability and longlife of the plants is depen-dent to a large degree onthe condition and functionalcapacity of the supportsemployed.
To avoid costly damageand operational breakdownthe regular inspection ofthermal movement inpiping systems and thecondition of supports -especially in older installa-tions - is urgently advised.
