    TYPE APPROVAL TESTING

    The G-LOK range of connectorshas been subjected to extensivestrain gauge and destructivetesting and has been awardedfull design approval by LloydsRegister.

    EXTERNAL LOADING

    TensionThe G-LOK connector is capableof withstanding higher tensileloads than a conventional ANSIflange. Tensile loads can causeconventional flange faces toseparate, providing a leak pathacross the flange face. With thepressure energised bore seal, thisdoes not occur and the G-LOKconnector will remain leak tight.

    BendingG-LOK connectors are designedto withstand severe bendingloads without leaking orloosening.Independent tests evaluatingG-LOK clamp connectors haveshown that even under severepressure and bending conditions,the connector does not leak andthe bolting remains tight.Increasing the bendingmovement to ultimate failure ofthe pipe has not resulted inconnector leakage.

    CompressionAs in most cases thebearing area of the sealring ribis larger than the cross section ofthe adjoining pipe it becomesimpossible to over compress thesealring within the G-LOKconnector. For normal pipingapplications, the compressivelimits are governed by otherfactors such as piping flexibilityanalysis or anchor loads and inpractice the G-LOK connectorwill always perform under theapplied compressive loading.

    Thermal ShockG-LOK connectors have beenapplied to both Cryogenic andhigh temperature service whichare subject to thermal transientconditions.For very severe thermal shock(i.e. quenching), the connectorscan be provided with thermalshrouds to protect the sealringlips from the full effects of thethermal shock.

    G-LOK The Advantages

    Pressure Temperature Rating Superduplex

    The G-LOK Connector is designed to offer thestrength and sealing integrity of a welded joint andthe versatility of a mechanical joint. It serves the sa-me purpose as a bolted flange assembly, with theadvantages of being more easily installed, lighterand smaller.A self-energized, pressure activated connection, theG-LOK, clamp-type connector consists of four basicelements:

    (1) Hub

    (2) Clamps

    (3) Seal

    (4) Bolting

    The hubs are usually welded to pipe; the seal is in-stalled and the bolting is tightened on the clamps toform a pipe connector that provides superiorstrength and leak integrity. The G-LOK is commonlyused in service with temperatures of up to 650C.The G-LOK also excels in high pressure applica-tions, with working pressure of 30,000 psi not un-common.The G-LOK clamp has been designed for the opti-mum strenght of a bolted connection. Since the boltsare at right angles to the axis of the pipe, they donot receive direct bending and pressure loads. Thissystem of clamping provides greater strength thanANSI or API flanges at a fraction of the seal sizeand weight as a result of this design. Less boltingtorque is required for proper seating of the seal.The design of the connector provides considerablestored energy in the system when compared withANSI or API flanges. This stored energy works toprovide leak resistance during thermal cycling andmaintains proper bolt loading.When properly installed, the G-LOK will usuallyprovide greater bending and torsional strength thanthe connecting pipe. The full face contact of the con-nector resists bending and ensures rigidity not provi-ded by other clamp-type connectors. The pressureand temperature limitations are determined only bythe materials of construction.

    HOW THE G-LOK CONNECTORS SEALS

    The seal ring in the G-LOK resembles a T in crosssection. The base of the T is the rib that is held byabutting hub faces as the connection is made up.The top of the T forms the lips that seal against theinner surfaces of the hubs.In the assembly of the connection, the clamps fit over

    the two hubs, and as they draw the hubs togetherthe seal ring rib ensures proper seal alignment.As the hubs are drawn together by the clamp as-sembly, the seal ring lips deflect against the innersealing surfaces of the hubs. This deflection elastical-ly loads the lips of the seal ring against the innersealing surface of the hub, forming the self-energi-zed seal. Internal pressure reinforces this seal, so thesealing action of the G-LOK is both self-energizedand pressure energized.

    G-LOK clamp connectors are interchangeable withother connectors designed and manufactured accor-ding to the same standard.

    Designed To Withstands Severe Conditions

    STANDARD SERIESClamp material-Low Alloy Steel

    The G-LOK connector has been designed formany different critical service applications. Manyof these involve rapid cyclic operating conditionsover extended periods of time, with various com-binations of both pressure and temperature. Toensure compliance with the applicable design co-des with regard to these severe thermal and pres-sure excursions, G-LOK utilizes state of the artengineering technology.Finite Element Analysis (FEA) allows the detailedexamination of all connector elements under the-se varying conditions.

    G-LOK CONNECTORS VS ANSI FLANGE

    G-LOK Finite Element Model

    The G-LOK clamp connection has a significantlysmaller diameter and a shorter lenght than that of acomparably rated ANSI or API ring joint flange con-nection, reducing weight and space required formake-up.The G-LOK is especially well suited to systems thatrequire close piping and hookup arrangements. Asthere are no bolt holes to align, the G-LOK clampmay be rotated to conveniently locate the bolts foreasy make-up and break-down of the connections.

    Sizing Selections

    Pressure Temperature Rating Stainless Steel

    HOW TO SELECTTHE G-LOK CONNECTOR

    1) Determine the following information needed tocorrectly size the G-LOK connector:

    Maximum Service Pressure and Temperature (YourDesign Conditions)

    The engineering or industry code your project hasspecified. (ASME VIII, B31.3, etc.)

    Pipe size and schedule or the I.D. and O.D. of theweld end.

    Your piping material.

    2) Refer to the tables in this catalogue:

    Locate your pipe size and schedule in the Buttweld hub table on pages 6 to 7, then read acrossto the corresponding hub size (third column). Asan example, the 4 schedule 40 Pipe requires aG-LOK Hub size of 4GR40. Also note that thischart has weights and dimensions for this hub andfor most popular hub sizes.

    The G-LOK number for the 4GR40 designates thecorrect clamp, bolting and seal ring sizes for thisconnection. The first number refers to the pipe andclamp size, in our example the pipe size is 4 andthe clamp would be the 4. More information onthe clamp can be located in the Clamp table onpage 11.

    The final set of numbers is the G-LOK seal for thisconnection (in our example this would be a 40).The G-LOK seal chart is located on page 10.

    3) Finally, refer to the pressure-temperature ratingcharts, on pages 14 to 19, to ensure that theG-LOK connector selected meets the design pressu-re and temperature requirements for the code towhich it is being specified.

    The standard line of G-LOK connectors andproducts are available in materials and sizesto fit nearly any requirement. But if your requi-rements, pipe size, material or design condi-tions, are not covered by one of our charts,please contact Galperti Engineering. We havean engineering and design staff ready to helpyou solve your most demanding needs.

    Assembly and Dis-Assembly Procedure

    INSPECT COMPONENTS PRIORTO ASSEMBLYHub and sealring seating surfaces must beclean and free from foreign matter. Damage tohub seats is not acceptable, and should be rec-tified before assembly.

    LUBRICATEUsually sealrings are coated which acts as lu-brificant during make-upe. If required light oilor MoS2 spray can be used. Take care that nosolid particles are present in the lubricant.

    CHECK SEALRING STANDOFFThe sealring should rock slightly against hubface.Stand-off dimensions given below in mm.

    ASSEMBLE COMPONENTSInstall sealring into the hubs, and assembleclamps around the hubs. Lubricant applied tothe hub/clamp contact area will aid assembly.The studbolts should be fitted ensuring thatspherically faced nuts locate into sphericalseats of the clamps. Lubrication of nut facesand bolt threads is recommended.

    TIGHTEN BOLTS IN UNIFORM MANNERBolting should be tightened to keep spacingbetween clamp halves approximately equal.Clamp segments should be shocked with suita-ble soft faced hammer to aid assembly. Alwaysre-t ighten bolts after shocking to thetorque/preload values given below.

    ALIGN HUBSHubs should be aligned so that sealring can beinstalled between hubs. DO NOT attempt tocorrect badly mis-aligned piping by clampingforce alone; piping pulling forces should onlybe released when clamps is fully assembled.

    ASSEMBLY

    DE-PRESSURISE THE LINEAlways check, never take for granted that theline has been de-pressurised. Proceed withcaution in case seepage has caused pressureto build up again.

    SLACKEN NUTS BUT DO NOT REMOVE THENUTS FROM THE BOLTS - THEN SLACKENCLAMP SEGMENTSGradually run the nuts back along the bolts un-til just loose. If clamp segments remain boundonto hubs, then BOTH segments must beslackened by hitting the inner face of the clamplugs with a suitable hammer.

    REPEAT SLACKENING PROCEDURERe-loosen nuts and re-slacken BOTH clampsegments until the maximum nut travel shownbelow is reached. This should release seal ringcontact and any residual pressure will then bereleased through, with the joint.

    CHECK CLAMPS ARE SLACK AND FREE TOROTATE AND/OR ROCK ABOUT HUBSDo not proceed until discharge ceases andclamps are slack, free to rotate or rock. NOTE- If pressure is still in the line, the sealring mi-ght remain seated, making the joint tight eventhough it is part dis-assembled. Dis-assemblycan be completed when clamps are free to mo-ve.

    DesignationsThe G-LOK connector designation (exam-ple 4 GR 40) designates the correct hub,clamp, bolting and sealring sizes. The firstnumber (4 in the example) refers to thehub and clamp size. The correct clamp canbe located in the clamp table on page 11.The second number in the designation(40 in the example) refers to the sealringsize. The correct sealring can be located inthe sealring table on page 10.

    G-LOK blind hubs are designed to savespace.Available for all standard size G-LOK con-nectors, they can carry the full basic pres-sure rating of the G-LOK connector.They can also be used as closures for pres-sure vessels and heat exchangers, and canbe drilled and tapped to incorporate instru-mentation, and customised to fit your speci-fic requirements.

    Assembly and Dis-Assembly Procedure

    INSPECT COMPONENTS PRIORTO ASSEMBLYHub and sealring seating surfaces must beclean and free from foreign matter. Damage tohub seats is not acceptable, and should be rec-tified before assembly.

    LUBRICATEUsually sealrings are coated which acts as lu-brificant during make-upe. If required light oilor MoS2 spray can be used. Take care that nosolid particles are present in the lubricant.

    CHECK SEALRING STANDOFFThe sealring should rock slightly against hubface.Stand-off dimensions given below in mm.

    ASSEMBLE COMPONENTSInstall sealring into the hubs, and assembleclamps around the hubs. Lubricant applied tothe hub/clamp contact area will aid assembly.The studbolts should be fitted ensuring thatspherically faced nuts locate into sphericalseats of the clamps. Lubrication of nut facesand bolt threads is recommended.

    TIGHTEN BOLTS IN UNIFORM MANNERBolting should be tightened to keep spacingbetween clamp halves approximately equal.Clamp segments should be shocked with suita-ble soft faced hammer to aid assembly. Alwaysre-t ighten bolts after shocking to thetorque/preload values given below.

    ALIGN HUBSHubs should be aligned so that sealring can beinstalled between hubs. DO NOT attempt tocorrect badly mis-aligned piping by clampingforce alone; piping pulling forces should onlybe released when clamps is fully assembled.

    ASSEMBLY

    DE-PRESSURISE THE LINEAlways check, never take for granted that theline has been de-pressurised. Proceed withcaution in case seepage has caused pressureto build up again.

    SLACKEN NUTS BUT DO NOT REMOVE THENUTS FROM THE BOLTS - THEN SLACKENCLAMP SEGMENTSGradually run the nuts back along the bolts un-til just loose. If clamp segments remain boundonto hubs, then BOTH segments must beslackened by hitting the inner face of the clamplugs with a suitable hammer.

    REPEAT SLACKENING PROCEDURERe-loosen nuts and re-slacken BOTH clampsegments until the maximum nut travel shownbelow is reached. This should release seal ringcontact and any residual pressure will then bereleased through, with the joint.

    CHECK CLAMPS ARE SLACK AND FREE TOROTATE AND/OR ROCK ABOUT HUBSDo not proceed until discharge ceases andclamps are slack, free to rotate or rock. NOTE- If pressure is still in the line, the sealring mi-ght remain seated, making the joint tight eventhough it is part dis-assembled. Dis-assemblycan be completed when clamps are free to mo-ve.

    Sizing Selections

    Pressure Temperature Rating Stainless Steel

    HOW TO SELECTTHE G-LOK CONNECTOR

    1) Determine the following information needed tocorrectly size the G-LOK connector:

    Maximum Service Pressure and Temperature (YourDesign Conditions)

    The engineering or industry code your project hasspecified. (ASME VIII, B31.3, etc.)

    Pipe size and schedule or the I.D. and O.D. of theweld end.

    Your piping material.

    2) Refer to the tables in this catalogue:

    Locate your pipe size and schedule in the Buttweld hub table on pages 6 to 7, then read acrossto the corresponding hub size (third column). Asan example, the 4 schedule 40 Pipe requires aG-LOK Hub size of 4GR40. Also note that thischart has weights and dimensions for this hub andfor most popular hub sizes.

    The G-LOK number for the 4GR40 designates thecorrect clamp, bolting and seal ring sizes for thisconnection. The first number refers to the pipe andclamp size, in our example the pipe size is 4 andthe clamp would be the 4. More information onthe clamp can be located in the Clamp table onpage 11.

    The final set of numbers is the G-LOK seal for thisconnection (in our example this would be a 40).The G-LOK seal chart is located on page 10.

    3) Finally, refer to the pressure-temperature ratingcharts, on pages 14 to 19, to ensure that theG-LOK connector selected meets the design pressu-re and temperature requirements for the code towhich it is being specified.

    The standard line of G-LOK connectors andproducts are available in materials and sizesto fit nearly any requirement. But if your requi-rements, pipe size, material or design condi-tions, are not covered by one of our charts,please contact Galperti Engineering. We havean engineering and design staff ready to helpyou solve your most demanding needs.

    Designed To Withstands Severe Conditions

    STANDARD SERIESClamp material-Low Alloy Steel

    The G-LOK connector has been designed formany different critical service applications. Manyof these involve rapid cyclic operating conditionsover extended periods of time, with various com-binations of both pressure and temperature. Toensure compliance with the applicable design co-des with regard to these severe thermal and pres-sure excursions, G-LOK utilizes state of the artengineering technology.Finite Element Analysis (FEA) allows the detailedexamination of all connector elements under the-se varying conditions.

    G-LOK CONNECTORS VS ANSI FLANGE

    G-LOK Finite Element Model

    The G-LOK clamp connection has a significantlysmaller diameter and a shorter lenght than that of acomparably rated ANSI or API ring joint flange con-nection, reducing weight and space required formake-up.The G-LOK is especially well suited to systems thatrequire close piping and hookup arrangements. Asthere are no bolt holes to align, the G-LOK clampmay be rotated to conveniently locate the bolts foreasy make-up and break-down of the connections.

    G-LOK The Advantages

    Pressure Temperature Rating Superduplex

    The G-LOK Connector is designed to offer thestrength and sealing integrity of a welded joint andthe versatility of a mechanical joint. It serves the sa-me purpose as a bolted flange assembly, with theadvantages of being more easily installed, lighterand smaller.A self-energized, pressure activated connection, theG-LOK, clamp-type connector consists of four basicelements:

    (1) Hub

    (2) Clamps

    (3) Seal

    (4) Bolting

    The hubs are usually welded to pipe; the seal is in-stalled and the bolting is tightened on the clamps toform a pipe connector that provides superiorstrength and leak integrity. The G-LOK is commonlyused in service with temperatures of up to 650C.The G-LOK also excels in high pressure applica-tions, with working pressure of 30,000 psi not un-common.The G-LOK clamp has been designed for the opti-mum strenght of a bolted connection. Since the boltsare at right angles to the axis of the pipe, they donot receive direct bending and pressure loads. Thissystem of clamping provides greater strength thanANSI or API flanges at a fraction of the seal sizeand weight as a result of this design. Less boltingtorque is required for proper seating of the seal.The design of the connector provides considerablestored energy in the system when compared withANSI or API flanges. This stored energy works toprovide leak resistance during thermal cycling andmaintains proper bolt loading.When properly installed, the G-LOK will usuallyprovide greater bending and torsional strength thanthe connecting pipe. The full face contact of the con-nector resists bending and ensures rigidity not provi-ded by other clamp-type connectors. The pressureand temperature limitations are determined only bythe materials of construction.

    HOW THE G-LOK CONNECTORS SEALS

    The seal ring in the G-LOK resembles a T in crosssection. The base of the T is the rib that is held byabutting hub faces as the connection is made up.The top of the T forms the lips that seal against theinner surfaces of the hubs.In the assembly of the connection, the clamps fit over

    the two hubs, and as they draw the hubs togetherthe seal ring rib ensures proper seal alignment.As the hubs are drawn together by the clamp as-sembly, the seal ring lips deflect against the innersealing surfaces of the hubs. This deflection elastical-ly loads the lips of the seal ring against the innersealing surface of the hub, forming the self-energi-zed seal. Internal pressure reinforces this seal, so thesealing action of the G-LOK is both self-energizedand pressure energized.

    G-LOK clamp connectors are interchangeable withother connectors designed and manufactured accor-ding to the same standard.
