Thorburn Flex IncFlexible Piping SpecialistComplete THORLOC make up requires two conditions.1) Hubs must be completely face to face with the rib ofthe sealring where standard hubs are used and completelyface to face with each other where recessedhubs are used.2) Bolts are made up to the correct torque.DisassemblyDe-pressurise the lineAlways check, never take it for granted that the line hasbeen de-pressurised. Proceed with caution in case seepagehas caused pressure to build up again.THORLOC ASSEMBLY/ DISASSEMBLYAssemblyInspect components prior to assemblyHub and sealring seating surfaces must be clean and freefrom foreign matter. Damage to hub seatsand seal lips is notacceptable, and should be rectified before assembly.LubricateUsually sealrings are coated which acts as lubricantduringmake-up. If required light oil or MoS2 spray can beused onhub sealing surface but not on sealring. Take care that nosolid particles are present in the lubricant.Check sealring stand-offThe sealring should rock slightly against hub face.Stand-off dimensions given below in inches.Assemble componentsInstall sealring into the hubs, and assemble clampsaround the hubs. Lubricant applied to the hub/clamp contactarea will aid assembly. The studbolts should be fitted ensuringthat spherically faced nuts locate into spherical seats ofthe clamps. Lubrication of nut faces and bolt threads is recommended.Tighten bolts in uniform mannerBolting should be tightened to keep spacing between clamphalves approximately equal. Clamp segments should beshocked with suitable soft-faced hammer to aid assembly.Always re-tighten bolts after shocking to the torque/preloadvalues given on facing page.Slacken nuts but do not remove the nuts from thebolts - then slacken clamp segmentsGradually run the nuts back along the bolts until just loose.If clamp segments remain bound onto hubs, thenboth segments must be slackened by hitting the inner faceof the clamp lugs with a suitable soft-faced hammer.Repeat slackening procedureRe-loosen nuts and re-slacken both clamp segments untilthe maximum nut travel shown below is reached. Thisshould release sealring contact and any residual pressurewill then be released through, with the joint.Check clamps are slack and free to rotate and rockabout hubsDo not proceed until discharge ceases ensure that hubs areapart, sealring is free to move and clamps are slack, free torotate or rock.NOTE - If pressure is still in the line, the sealring might remainseated, making the join`t tight even though it is partdis-assembled. When all components are loose and theclamps are free to move can dis-assembly be completed. Ifthe components are not free to move DO NOT CONTINUE- contact your supervisor.Bolt Torque RequirementsClamp Size11 1/22Stud Bolt Size1/2 - 13UNC-25/8 - 11UNC-23/4 - 10UNC-2Stud Bolt Length(Inches)3 1/255 1/4, 6AverageTorque173555Align hubsHubs should be aligned so that sealring can be installed betweenhubs.

CANDUNUCLEARHow Thorburn THORLOC Connectors WorkTHORLOC is an innovative pipe clamp connector which allowsquick connect and disconnect capabilities and is anideal connector where space, weight and joint integrity arecritical requirements. These features make THORLOC a superioralternative to ANSI & DIN flanges.ClampSpherical NutSeal RingTHORLOC pipe clamp connectors are designed to be interchangeablewith Grayloc type pipe clamp connectors. Thorburn’sTHORLOC is designed and registered to meet all therequirements of ASME Section III, Class 1, 2, 3, 6, CSA Can3 N285.0 and ASME Section VIII division 1 & 2.Threaded StudThe sealing ring is an inverted “T” with therun portion having two conicle surfaces.The conicle surfaces of the sealing ring interfaceagainst the hub sealing surface toprovide a metal-to-metal seal.The conicle portionof the sealing ringslides into the huband engages theseal by elasticallydeflecting againstthe hub’s sealingsurfaces.Seal Ring(Inverted “T”)Butt Weld HubTHORLOC is a four bolt pipe clamp connector consistingof two butt weld hubs that are welded to connectingpipes, two clamps (180º segments) which are rotatedaround the hubs and one sealing ring which fits betweenthe two hubs.THORLOC pipe clamps fit over the hubsand as the nuts are torqued the clampsdraw the hubs together.The bolt set consists of four studs and four sphericallyfaced nuts which mount the clamps over the hubs andengages the assembly.Thorburn THORLOC Pipe Clamp cutawayfully assembled© 2013 Thorburn Flex Inc

Thorburn Flex IncFlexible Piping SpecialistTHORLOC Sealing AdvantageThorburn’s THORLOC four main components include, hubs,sealring, clamps and bolting. THORLOC does not rely on theconventional flange gaskets or correctly tensioned bolting tomaintain seal integrity. When bolting the assembly, the hubsare drawn together by the twin wedge action of the two clampsegments compressing on the seal ring to make a self-energizingseal.CLAMPINGFORCESEAL SURFACECLAMPINGFORCESEAL SURFACETHORLOC seal ring and hubs are made of different materialshaving their own unique hardness and thermal properties thatenhances the seal as temperature changes are encountered.In service the sealring becomes even more effective as internalpressure reinforces the metal-to-metal seal to the extentthat its strength can normally exceed the burst pressure ofthe connected pipe.Withstanding External Pipe LoadsExternal bending forces are an inevitable part of any pipingsystem, resulting in high stresses being placed on pipe joints.THORLOC’s applied bolting loads are transmitted to theclamps through almost 360º contact with the hubs. As thebolts are transversely mounted they are almost completelyisolated from the operating loads, resulting in a strong, reliableyet compact connection. This feature allows THORLOCto withstand considerable bending forces and axial loadingunder pressure without leaking or the bolts becoming loose,greatly reducing maintenance costs at the same time asbeing highly beneficial to the environment.Tension Bending CompressionPRESSUREAfter Assembly: Pressure Energized SealTHORLOC Pipe Clamp BenefitsUp to 75% lighter and significantly smaller than ANSI flanges25% smaller clamp diameter & 40% shorter connection lengthEasier fabrication and installation with no bolt holes to alignOnly 4 bolts to tighten rather than up to 24 on an ANSI flangeTHORLOC can be rotated around the hub for easy boltorientation and tighteningAncillary components such as valves and piping layouts canbe installed without worrying about bolt hole alignmentQuicker and easier make-up and breakout minimizesmaintenance downtimeLower bolt torque: typically 50% less than that for a ring jointflangeSealing integrity is unaffected by over-tensioning boltsTHORLOC can be assembled or disassembled in the time ittakes for a single ANSI flange connectionIt is not usually necessary to re-tighten bolts once in serviceOne clamp size is required for each nominal pipe sizeReusable sealrings give greater flexibility for hydro-testing andcommissioning prior to serviceAvailable in standard 316 stainless steel (other materialsavailable upon request)Thorburn’s THORLOC pipe clamp connector, as compared to conventionANSI flanges, are capable of withstanding higher tensileloads, more severe bending loads and prevent compressive forceoverloads, all the while, maintaining a gas tight seal.THORLOC Pipe Connectors can be used in applicationswhere design pressures up to 30,000 psi are found. THOR-LOC’s energized seal, light weight, compactness and simplicityto install make it an extremely versatile and valueadded pipe connector.THORLOC 2 inchPipe Clamp ConnectorANSI 2 inch 2500 lbsFlange Connectorwww.thorburnflex.com

THORLOC BUTT WELD HUBTHORLOC Butt Weld Hubs are usually suppliedready to be welded to pipe or as an integral connectoron any associated piping equipment. During assemblyas the clamps draw the hubs together usingthe angular outer shoulders of the hubs, the seal ringis deflected against the hub seating surfaces creatinga pressure tight seal. Internal pressure reinforces thisseal so that it is both self energized and pressuresealed.CANDUNUCLEARTECHNICAL DATAMaterial: SA-479 Type 316/316LDesign Pressure: 3700 psig (255 bar)Design Temperature: 450ºF (232ºC)NUCLEAR CLASS:To Specify ASME Section III Code Class - Replace "X" withNC1 (Class 1), NC2 (Class 2), NC3 (Class 3).For Class 6 (Leave Blank)For ordering information - See back coverNomPipeSizeScheduleorWeightStainless Steel Part NumberApproxWeight(lbs)SealRingSizeClampSizePipe OD Pipe ID Dimensions (Inches)(Inches) A B C D EF180160N1616TL-80-BWH-S6-XN1616TL-160-BWH-S6-X0.540.66117111.3151.3150.9570.8152.0002.0001.7501.7501.5001.5000.3130.3131 1/280160N2424TL-80-BWH-S6-XN2424TL-160-BWH-S6-X1.832.0114141 1/21 1/21.9001.9001.5001.3383.1253.1252.3752.3752.3752.3750.4370.437280160N3232TL-80-BWH-S6-XN3232TL-160-BWH-S6-X2.592.932020222.3752.3751.9391.6893.6253.6252.7502.7502.8752.8750.4370.4372 1/280160N4040TL-80-BWH-S6-XN4040TL-160-BWH-S6-X6.367.1625202 1/2-32 1/2-32.8752.8752.3232.1255.0005.0003.2503.2504.0004.0000.5000.500380160N4848TL-80-BWH-S6-XN4848TL-160-BWH-S6-X5.506.5327252 1/2-32 1/2-33.5003.5002.9002.6245.0005.0003.2503.2504.0004.0000.5000.500480160N6464TL-80-BWH-S6-XN6464TL-160-BWH-S6-X7.8010.134034444.5004.5003.8263.4386.0006.0003.6253.6255.0005.0000.5000.500© 2013 Thorburn Flex Inc
