Selection Guide

Many factors affect thesuitability of a gasket in agiven application making itdifficult to determine whichis the correct one for theduty. In heat exchangerapplications, factors such as relative flange movementcan complicate gasketselection still further and it is important that theattributes of each gaskettype are fully understood.

To help you make aninformed choice on gasketselection the table below lists the advantages anddisadvantages of each gasketunder various conditions.

This table should be used as a general guide for selection only.

2 Metallic Gaskets

Camprofile GasketsCamprofile Gaskets consist of a metal core, generally stainlesssteel, with concentric grooves on either side. A sealing layer isnormally applied to both faces and depending on the service the material for this layer can be graphite, PTFE, Novus sheetmaterial, Hi-temp or metal (e.g. aluminium or silver).Camprofile gaskets are ideal forboth standard pipe and heatexchanger applications.

Corrugated GasketsCorrugated Metal Gaskets consist of a corrugated metalcore, normally stainless steel, with a soft facing layer applied to each face. The corrugationsprovide resilience and reduce thesealing surface area of the gasketwhile the soft layer ensuresoutstanding sealing, even at lowloads. Particularly suited as areplacement to metal jacketedgaskets.

Spiral Wound GasketsSpiral Wound Gaskets consist of a ‘V’ shaped metal strip spirallywound in combination with a softfiller material, normally graphite,PTFE or Hi-Temp. The metal stripprovides outstanding recoverywhilst the flexible filler ensuresexcellent sealing. Depending onthe application the gasket can bespecified with outer and/or innerrings.

Metal Jacketed GasketsMetal Jacketed Gaskets consist of soft filler material encapsulatedin a metallic material. The fillermaterial provides the gasket with compressibility and resiliencewhile the jacket conferscompressive strength and blow out resistance.

Ring Type JointsRing Type Joints are designed to concentrate the bolt load overa small area thus producing highseating stresses. As the ring typematerial should always be softerthan the mating flanges, the highseating stress causes ‘plastic-flow’ of the ring joint in the flange faces creating the seal.

Gasket ProfilesAll profiles feature as standard a 1mmcam pitch and a maximum groovedepth of 0.5mm. Alternative profilesare available on request e.g. 1.5mmcam pitch and a maximum groovedepth of 0.75mm (DIN profile).

Profile Selection

With or without centering ringCamprofile gaskets with centeringrings ensure optimum gasketpositioning between the bolts.

Loose or integral centering ringsThermal shock conditions maydamage camprofiles with integralcentering rings (thermal tension maycause cracks in the core). This isprevented by using camprofilegaskets with loose or floating guiderings.

The centering rings on styles M21LMand M41LM allow for expansion and contraction without reactionaryforces being applied to the core.

Optimal gasket performance isultimately ensured by the quality of flange surface finish and correctassembly.

Camprofile Gasket shapesIn addition to the round profiles,gaskets can be made in a variety ofshapes, oval, rectangular andexchanger with pass bars.

Correctly dimensioned gasketdrawings are required to make non-standard gaskets and gasket shapes.

Camprofile GasketCharacteristics

Camprofile gaskets consist of a metal core, generallystainless steel, with concentricgrooves on either side. A sealing layer is usuallyapplied on both sides anddepending on the service thematerial for this layer can begraphite, PTFE (Teflon), Novussheeting material, Hi-temp or metal (e.g. aluminium orsilver). Camprofiles can beused without sealing layersto provide an excellent sealbut there is a risk of flangesurface damage especially at high seating stresses. The sealing layers protect the flange surface fromdamage in addition toproviding an excellent seal at low bolt stress.

PropertiesCamprofiles have a number ofproperties which make themunique:

• Highly suitable for varyingtemperatures and pressures

• Less sensitive to assemblyfaults (inaccurate bolttightening)

• Suitable for light and heavydesigned flanges

• Dependent upon the layermaterial camprofile gasketscan resist temperatures up to1000OC

• Resistant to media pressures> 400 bar

• When assembled the remainingthickness of the sealing materialis extremely low (0.1 - 0.2mm),thus reducing leaks, fail ratesand environmental pollution

• The gasket will not damage theflange surface and can be easilyremoved

• Camprofile cores are re-usableafter cleaning, inspection andrelayering with new sealingmaterial. This is of particularinterest in the case of heatexchanger gaskets

• Reduces maintenance costs andleakage - thanks to camprofile’shigh sealing performance andreliability.

Seating Stress RangeThe camprofile gasket offers reliablesealing performance when seatedwithin the following seating stressranges. The below are based on parallel form gaskets. The values haveslight variations for convex forms ofcamprofiles.

Flange Surface FinishThe recommended flange surfacefinish for camprofiles with sealinglayers is from 3.2 to 6.3μm Ra (125-250 RMS), this is also referredto as a smooth finish.

Core Material Selection

Core MaterialThe core material is generallyfabricated in material identical to thepiping system to prevent corrosionproblems.

Stainless Steel 316L camprofilescores are generally used with carbonsteel pipe systems to prevent gasketcorrosion.

The recommended camprofile metalcores are shown in the table below.

Camprofile Gaskets M21L and M41LDuring recent years, modified gasketshave been introduced and these arenow included in our manufacturingprogramme.

Generally camprofile gaskets aremanufactured with a 0.5mm thickfloating centering ring. Based onintensive research and practical tests,in cooperation with major users, a1.5mm thick floating centering ringwas developed featuring a uniqueouter edge attachment.

The M21LM and M41LM stylesoffer the following advantages:

• The floating centering ring is stableand free from expansion stresses

• No distortion of the centering ringby the threads of the bolts, assometimes occurs in verticalassemblies, causing the camprofileto be positioned eccentrically.This also increases the possibilityof re-use, reducing costs

• User friendly - the 1.5mm thickguide ring reduces the risk ofoperator injury during handling

• The floating guide ring allowsfor expansion without applyingmechanical stress to the camprofilecore.

Corrugated GasketCharacteristics

Novus corrugated gasketscomprise a corrugatedmetallic core, normallystainless steel, with a softfacing layer applied to eachface. The corrugations provideresilience and reduce thesealing contact surface areaof the gasket while the softlayer ensures outstandingsealing, even at low loads.These gaskets are particularlysuited for heat exchangerapplications as a replacementto metal jacketed gaskets.

Properties• Excellent resistance to

radical shear

• Creates a tight seal at lowbolt loads

• Can be used when there isinsufficient bolt load to sealspiral wound gaskets

• Outstanding resistance tothermal cycling

• Safe to handle and fit

• Excellent thermal andchemical stability

• Tolerant to flangeimperfections

Practical Benefits• No sharp edges for safe

handling

• Excellent rigidity ensures easyposting between flanges

• Does not stick to flanges

Heat Exchanger ApplicationsHeat exchanger flanges, owing to thedifference in thickness of the matingflanges, heat and expand at differentrates.

This differential expansion can causeradial shearing of the gasket andtherefore it is critical that a gasket isselected which resists radial shearand maintains a seal even underthermal cycling conditions.

Corrugated metal gaskets have aproven record in problematicexchanger applications, offering lowrelaxation, high resistance to radialshear and high levels of tightness.For this reason these gaskets arereplacing more traditional gasketstyles such as metal jacketedparticularly on these applications.

Gasket Stress Range:

Type SGThe standard spiral wound gasketformat identical to Novus RF1 butfitted with an outer centering ring(applied to raised face flanges).An integral centering guide ringensures fast, accurate centeringof the gasket on the flange.Provides additional radial strengthto prevent gasket blow-out andacts as a compression stop.

Type RF-IRSpiral wound gasket formale/female flangesconsisting of a woundcomponent fitted with aninner ring to bring the gasketflush with the pipe bore toprevent inward buckling.

Type SG-IRIdentical to Novus SG butalso fitted with an innerring to prevent inwardbuckling at the windings.

Type HX-RThis type of gasket consists of a wound component fitted with a narrow wound centering ring.Centering windings ensurecorrect centering in flush flanges(e.g. in heat exchangers).

Type RF1The gasket consists of a sealing filler and V-shapedmetal strip wound incombination. This profileis usually applied totongue/groove flanges.

Type SG-RTJA standard spiral woundgasket (SG Type) withdimensions tailored to Ring Joints (RTJ) flanges.

Type HX-RIRThis gasket is identical to HX-R but also fitted with an inner ring, rendering thisgasket type suitable formounting in male and femaleflanges.

Type WLThis gasket is identical to RF1 but fitted with an outer winding.Centering is achieved by positioningthe winding over two bolts oppositeeach other.

Type HEFitted with pass partition bars for useon heat exchangers and vessels, thisgasket type is otherwise identical tothe RF1 profile. Metal - jacketed barshave a thinner design than that ofspiral wound gasket material.

The bars are fixed through welding.

Type HE-SGFitted with an outer centering ring,the HE-SG is otherwise identical tothe HE profile.

Type HE/SG-IRFitted with an outer centering ringand an inner ring, the HE/SG-IR isotherwise identical to the HE profile.

Special ShapesSpiral wound gaskets can be producedin a wide variety of shapes, such asoval and pear-shape, with passpartition bars and many other types.Generally, the pass partition bars onspiral wound gaskets aremanufactured as metal-jacketed bars.A variety of alternatives are available.

Type MHThis spiral wound gasket is identical to the RF1 profile but oval shaped to fit manholes.

Type TC/HHThis type of gasket is for hand holesand special flange assemblies (tubecap and hand hole covers). They areavailable in square, rectangular, oval,diamond and pear shapes.A drawing specifying the correctdimensions are required tomanufacture special shapes.

Special Profiles

Profile with a GT - ZoneIn the event of a graphite filled spiralwound gasket possibly causing anundesirable reaction between thegraphite and the medium to besealed, or of possible mediumcontamination, the problem can besolved by using a spiral wound gasketwith a GT - Zone.

The spiral wound element of a NovusGT - Zone gasket consists of outerwindings of Hi-Temp material with acentral winding zone made ofgraphite or PTFE (depending on theoperating conditions) to improve gastightness. This results in a spiralwound gasket with the followingproperties:

• Can be used at highertemperatures

• Has excellent sealing properties

Combined with the other advantagesof a spiral wound gasket, the spiralwound with a GT - Zone may be usedin a wide range of operatingconditions and applications.

Guide Rings and Material Selection

Benefits of the Centering RingThe spiral wound gasket outer centeringring provides the following benefits:

• Optimum location between the bolts

• Protection of the spiral wound element

• Additional security against gasketblow-out

• Acts as compression limiter preventingoverloading and over compression ofthe spiral wound element

• Prevents radial-flow of soft fillers,1such as PTFE.

For these reasons it is preferable to usespiral wound gaskets with outer centeringrings.

The outer ring is marked with nominal size,pressure class, standard and materials.

Benefits of the Inner Ring The spiral gasket inner ringprovides the following benefits:

• Prevents radial-flow of softfillers, such as PTFE + Graphite

• Reduces turbulence-minimisingflow resistance

• Acts as a heat shield when thespiral wound gasket issubjected to high temperatures.

Inner and outer rings areparticularly recommended for useon spiral wound gaskets exceedingclass 600lbs, but specificallyrecommended for hightemperatures and pressures tooptimise the operational reliabilityof the spiral wound sealingelement. Inner rings are mandatoryfor PTFE filled spirals.

Material SelectionThe material selected for the innerring and winding metal is usuallythe same as the flange metal. Thisprevents corrosion and differentialexpansion problems. The outercentering ring is generallymanufactured from carbon steel with an anti- corrosion treatment.However, the ring may also bemanufactured in the same metal asthe flange to prevent corrosionproblems.

Filler Material Selection

The table opposite may be used toselect the correct filler. It should bepointed out that graphite will be theoptimum filler in most cases. Onlywhere graphite could cause mediacontamination, or is not chemicallyresistant, should the use of anothertype of filler material berecommended. In such cases, analternative solution might be toselect a gasket with a GT-zone.

GraphiteGraphite is universally chosenbecause of its good chemicalresistance, resistance to ageing,good gas tightness and ability tooperate at high temperatures.

APX2APX2 is an oxidation resistantgraphite which offers the sameexcellent sealing characteristics ofgraphite but can be used at higherservice temperatures.

One-piece

Metal Jacketed GasketCharacteristics

Metal jacketed gasketsconsist of a metal cover and a ‘soft’ sealing material filler.

The sealing filler providesoutstanding resilience, whilethe metal jacket guaranteesgood sealing and protects thefiller against pressureconditions, fluctuatingtemperatures and corrosion.

A wide variety of materials are available to guaranteesatisfactory sealing. Themetals listed on the next pageare standard, other metals areavailable on request.

This type of gasket is beingreplaced by either Camprofiles(see pages 4-7) orcorrugated metal products(see pages 8-9).

Welded

Welded bar metal jacketed gasketsoffer the following benefits overone-piece gaskets with integral bars:

• Lower price - Typical cost savings10% to 40% (depending onmaterial)

• Quicker delivery - Less timeto manufacture

• Technically superior and safer- Extra sealing safeguards give abetter gasket

• Longer sealing life - Bars sealindependently of the outer ring.

Welded Metal JacketedGasketsWelded metal jacketed gaskets aremanufactured in a wide range of sizesand styles. Generally they are used in Heat Exchangers, Vessels, Pumps,Autoclaves, Engines, Valves, andExhaust Systems.

Metal jacketed gaskets requiremachined flange faces, high bolt loadsand exact flange alignment to ensurean effective seal. It is for this reasonthat we recommend the use ofCamprofile or Corrugated MetalGaskets for most applications.

Installation of Novus Metallic Gaskets

In order to ensure theoptimum service life of Novusmetallic gasket materials it isnot only important to choosethe correct material for theapplication but to install and maintain it correctly.

The following guidelines aredesigned to assist the enduser in the assembly ofNovus gasket materials.

Gasket• Always use a new gasket

• Check that the gasket is in goodcondition and that the dimensionsare correct for the class and sizeof the flanges

• Do not use jointing compounds,grease or lubricants with Novusmetallic gasket materials. Thesecompounds can affect the contactfriction between the gasket and theflange and can lead to creep andpremature joint failure

• If there is a requirement to fix thegasket to the flange prior toassembly (e.g. large vertical flanges)then a light dusting of sprayadhesive e.g. 3M 77 spray maybe used. The adhesive should beapplied sparingly and in isolatedareas, and must be compatiblewith the fluid medium.

Bolting• Ensure the bolt and nut threads

are clean. Apply bolt lubricationto the bolt and nut threads and tothe face of the nut to be tightened.Do not apply grease or boltlubricant to the joint face. Aftercleaning and lubrication it shouldbe possible to run the nut alongthe full length of the bolt by hand.If this is not possible the bolts andnuts should be refurbished orreplaced

• Scrape, wire brush or file asnecessary the back face of eachflange where the bolt heads andnuts are to sit, ensuring that thesurfaces are clean and flat

• If possible use hardened flatwashers to ensure even transferof the load.

Installation• Ensure that the gasket is installed

centrally

• It is recommended that the boltsare tightened using a controlledmethod such as torque or tension.If using a torque wrench, ensurethat it is accurately calibrated

• Tighten bolts in a star-like crossingpattern in the following sequence

• Finger tighten nuts

• Tighten to 30% of the final load

• Tighten to 60% of the final load

• Tighten to full load

• Make a final tightening sequence,working around the flange,tightening each bolt in turn untilthe specified torque is achieved.

After InstallationCheck that the flange faces areparallel using a suitable tool e.g. Novus Flange Gap Tool (below).

Flange Condition• Remove the old gasket and check

that the flange faces are clean andfree from indentations and scoring.Radial (cross face) scoring is aparticular concern and can lead tojoint leakage

• For camprofiles, corrugated metaland spiral wound gaskets, a surfacefinish of between 3.2μm to 6.3μmRa (125 to 250 micro inch) isrecommended; for metal ring joints asurface finish of between 0.8μm and1.6μm is recommended (dependenton style) and for metal jacketedgaskets a surface finish of 1.6μm Rais recommended. Use a surface finishcomparator e.g. Novus comparatorto check flange finish (right).

• Check that the flangefaces are parallel orthat the pipework issufficiently flexibleto allow the flanges tobe pulled parallel andconcentric withoutexcessive bolt loads.

Ring Type Joint ProfilesType R Ring Type Joints

Novus models M8 and M9

M8 model R oval section and M9model R octagonal section ring typejoints are designed for flanges withstandard ring type grooves. Thesestandard shapes are used to sealpressures up to 5,000 psi inaccordance with API 6A.

The octagonal cross section has ahigher sealing efficiency than the oval cross section and is thereforepreferred. The oval section ring jointswere originally designed for the nowobsolete round bottom groove. Boththe oval and the octagonal crosssection are interchangeable on the flat bottom groove design.

We suppy a range of specialisedRing Type Joints for critical andnon standard applications to suitthe requirements of thepetrochemical industry.

Cam-ORJThe Cam-ORJ is a standard API 6Aoctagonal ring joint but with the fourangled seating surfaces concentricallyserrated and faced with oxidationinhibited graphite. The gasket offersthe high sealing efficiency associatedwith the octagonal design but withthe added benefit of being capable ofsealing flanges with minor damage.Under compression the graphiteflows into minor imperfectionscreating a tight seal.

The Cam-ORJ is available in a rangeof Alloy materials and in sizing to suitASME B16.5 or API 6A flanges.

Novus model M8R and M9R

Rubber Coated Ring Type Joints

This is an octagonal/oval section ringtype joint generally soft iron or lowcarbon steel totally enclosed in anitrile rubber coating. Widely used inpressure testing procedures,minimising any damage to the flange.

Ring Type Joints

Ring type joints are designedto concentrate the bolt loadover a small area thusproducing high seatingstresses. As the ring typematerial should always besofter than the matingflanges, the high seatingstress causes ‘plastic-flow’ of the ring joint in the flangefaces creating the seal.

Type RX Ring Type Joints

Novus model M12/M12S

M12 model RX ring type joints aredesigned for pressures up to 5,000psi.

A pressure activated ring joint, itsshape is designed so that the fluidpressure increases sealability. The outside sealing surface of thering joint makes the initial contactwith the flange. As the internalpressure rises the contact pressurebetween ring joint and flange alsoincreases. This is sometimes referredto as a pressure activated ring joint.due to the shape of the gasket. High seating pressures are createdincreasing the sealability. This designcharacteristic makes the RX ring jointmore resistant to vibrations, pressuresurges and shocks that occur duringoil well drilling.

M12S Model SBX ring type joint isthe same in design to the RX ring,however, the suffix ‘S’ indicates thatadditional pressure equalisation holeshave been drilled in accordance withAPI 17D for use on sub sea wellheadand christmas tree equipment.

M12

Novus model M12PI

Ring Type Joints with PTFE Inserts

M12 model RX ring type joints can be supplied with PTFE inserts.Designed to reduce turbulent flowand eliminate ring joint and flangecorrosion. The insert is speciallydesigned with radially drilled holesensuring the self-energisingperformance is not affected. Theinsert is located between the insidediameter of the ring joint and thebore of the flange. On assembly, the insert is captured between theflanges, filling the void between ringjoint and flange bore.

Blind Ring Type JointsThese specialised ring type joints aredesigned and manufactured for thecustomer who has a requirement toblank off flanges and pipe work. Thejoints are standard rings but with amachined metallic centre.

Blind ring type joints can be suppliedin a variety of materials.

RX Ring Type Joint

PTFE InsertType BX Ring Type Joints

Novus model M11/M11S

M11 model BX ring type joints aredesigned for pressures up to 20,000psi, suitable only for use with APItype BX flanges and grooves.

The gasket has a square cross sectionwith bevelled corners. The averagediameter of the ring joint is slightlygreater than that of the flangegroove. This way, when the ring jointis seated, it stays pre-compressed bythe outside diameter, creating high seating stress.

The M11S Model SBX ring type jointis the same design as the BX ring,however the suffix ‘S’ indicates thatadditional pressure equalisation holeshave been drilled in accordance withAPI 17D for use on sub sea wellheadand christmas tree equipment.

Seating StressTo achieve a reliable seal, the ringtype joint should be assembled withinthe seating stress parameters shownin the table above.

Flange Surface FinishThe ring type joint and the sealingface of the groove must be free ofindentations, score marks, tool andchatter marks.

The maximum flange surface finishfor M8, M9, model R, M12 model RX is 1.6μm RA (63RMS).

The maximum flange surface finishfor M11 model BX is 0.8μm RA(32RMS).
