The G-LOK ® Connector is designed to offer the strength and sealing integrity of a welded joint and the versatility of a mechanical joint. It serves the same purpose as a bolted flange assembly, with the advantages of being more easily installed, lighter and smaller. A self-energized, pressure activated connection, the G-LOK ®, clamp-type connector consists of four basic elements: • (1) Hub • (2) Clamps • (3) Seal • (4) Bolting The hubs are usually welded to pipe; the seal is installed and the bolting is tightened on the clamps to form a pipe connector that provides superior strength and leak integrity. The G-LOK ® is commonly used in service with temperatures of up to 650°C. The G-LOK ® also excels in high pressure applications, with working pressure of 30,000 psi not uncommon. The G-LOK ® clamp has been designed for the optimum strenght of a bolted connection. Since the bolts are at right angles to the axis of the pipe, they do not receive direct bending and pressure loads. This system of clamping provides greater strength than ANSI or API flanges at a fraction of the seal size and weight as a result of this design. Less bolting torque is required for proper seating of the seal. The design of the connector provides considerable stored energy in the system when compared with ANSI or API flanges. This stored energy works to provide leak resistance during thermal cycling and maintains proper bolt loading. When properly installed, the G-LOK ® will usually provide greater bending and torsional strength than the connecting pipe. The full face contact of the connector resists bending and ensures rigidity not provided by other clamp-type connectors. The pressure and temperature limitations are determined only by the materials of construction.
G-LOK ® – The Advantages the two hubs, and as they draw the hubs together the seal ring rib ensures proper seal alignment. As the hubs are drawn together by the clamp assembly, the seal ring lips deflect against the inner sealing surfaces of the hubs. This deflection elastically loads the lips of the seal ring against the inner sealing surface of the hub, forming the self-energized seal. Internal pressure reinforces this seal, so the sealing action of the G-LOK ® is both self-energized and pressure energized.

The seal ring in the G-LOK ® resembles a “T” in cross section. The base of the “T” is the rib that is held by abutting hub faces as the connection is made up. The top of the “T” forms the lips that seal against the inner surfaces of the hubs. In the assembly of the connection, the clamps fit over

Designed To Withstands Severe Conditions
The G-LOK ® connector has been designed for many different critical service applications. Many of these involve rapid cyclic operating conditions over extended periods of time, with various combinations of both pressure and temperature. To ensure compliance with the applicable design codes with regard to these severe thermal and pressure excursions, G-LOK ® utilizes state of the art engineering technology. Finite Element Analysis (FEA) allows the detailed examination of all connector elements under these varying conditions.

G-LOK ® CONNECTORS VS FLANGES G-LOK ®
The G-LOK ® clamp connection has a significantly smaller diameter and a shorter lenght than that of a comparably rated ANSI or API ring joint flange connection, reducing weight and space required for make-up. The G-LOK ® is especially well suited to systems that require close piping and hookup arrangements. As there are no bolt holes to align, the G-LOK ® clamp may be rotated to conveniently locate the bolts for easy make-up and break-down of the connections.

Sizing Selections
HOW TO SELECT THE G-LOK ® CONNECTOR 1) Determine the following information needed to correctly size the G-LOK ® connector: • Maximum Service Pressure and Temperature (Your Design Conditions) • The engineering or industry code your project has specified. (ASME VIII, B31.3, etc.) • Pipe size and schedule or the I.D. and O.D. of the weld end. • Your piping material. 2) Refer to the tables in this catalogue: • Locate your pipe size and schedule in the Butt weld hub table on pages 6 to 7, then read across to the corresponding hub size (third column). As an example, the 4” schedule 40 Pipe requires a G-LOK ® Hub size of 4GR40. Also note that this chart has weights and dimensions for this hub and for most popular hub sizes. • The G-LOK ® number for the 4GR40 designates the correct clamp, bolting and seal ring sizes for this connection. The first number refers to the pipe and clamp size, in our example the pipe size is 4” and the clamp would be the 4. More information on the clamp can be located in the Clamp table on page 11. • The final set of numbers is the G-LOK ® seal for this connection (in our example this would be a 40). The G-LOK ® seal chart is located on page 10.

SEALRING SIZE 40
3) Finally, refer to the pressure-temperature rating charts, on pages 14 to 19, to ensure that the G-LOK ® connector selected meets the design pressure and temperature requirements for the code to which it is being specified.
The standard line of G-LOK ® connectors and products are available in materials and sizes to 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 have an engineering and design staff ready to help you solve your most demanding needs.
HOW TO ORDER THE G-LOK ® CONNECTOR After following the selection procedures the information necessary for ordering G-LOK ® connectors is the quantity, the hub number and material, the seal number and seal material, and the clamp number and clamp material. A G-LOK ® assembly consists of the following: • Two G-LOK ® Hubs • One G-LOK ® Clamp Set, with four studs and eight nuts (Spherical washer available on request) • One G-LOK ® Seal Ring

Assembly and Dis-Assembly Procedure
ASSEMBLY
DIS-ASSEMBLY INSPECT COMPONENTS PRIOR TO ASSEMBLY Hub and sealring seating surfaces must be clean and free from foreign matter. Damage to hub seats is not acceptable, and should be rectified before asse mbly. LUBRICATE Usually sealrings are coated which acts as lubrificant during make-upe. If required light oil or MoS2 spray can be used. Take care that no solid particles are present in the lubricant. CHECK SEALRING STANDOFF The sealring should rock slightly against hub face. Stand-off dimensions given below in mm.

ASSEMBLE COMPONENTS Install sealring into the hubs, and assemble clamps around the hubs. Lubricant applied to the hub/clamp contact area will aid assembly. The studbolts should be fitted ensuring that spherically faced nuts locate into spherical seats of the clamps. Lubrication of nut faces and bolt threads is recommended. TIGHTEN BOLTS IN UNIFORM MANNER Bolting should be tightened to keep spacing between clamp halves approximately equal. Clamp segments should be shocked with suitable soft faced hammer to aid assembly. Always re-tighten bolts after shocking to the torque/preload values given below. ALIGN HUBS Hubs should be aligned so that sealring can be installed between hubs. DO NOT attempt to correct badly mis-aligned piping by clamping force alone; piping pulling forces should only be released when clamps is fully assembled. CLAMP SIZE

DE-PRESSURISE THE LINE Always check, never take for granted that the line has been de-pressurised. Proceed with caution in case seepage has caused pressure to build up again. SLACKEN NUTS BUT DO NOT REMOVE THE NUTS FROM THE BOLTS - THEN SLACKEN CLAMP SEGMENTS Gradually run the nuts back along the bolts until just loose. If clamp segments remain bound onto hubs, then BOTH segments must be slackened by hitting the inner face of the clamp lugs with a suitable hammer. REPEAT SLACKENING PROCEDURE Re-loosen nuts and re-slacken BOTH clamp segments until the maximum nut travel shown below is reached. This should release seal ring contact and any residual pressure will then be released through, with the joint. X CLAMP SIZE MM STANDARD CLAMP SERIES

EXTERNAL LOADING Tension The G-LOK ® connector is capable of withstanding higher tensile loads than a conventional ANSI flange. Tensile loads can cause conventional flange faces to separate, providing a leak path across the flange face. With the pressure energised bore seal, this does not occur and the G-LOK ® connector will remain leak tight.
Bending G-LOK ® connectors are designed to withstand severe bending loads without leaking or loosening. Independent tests evaluating G-LOK ® clamp connectors have shown that even under severe pressure and bending conditions, the connector does not leak and the bolting remains tight. Increasing the bending movement to ultimate failure of the pipe has not resulted in connector leakage.

Quality Type Approval & Testing Compression As in most cases the bearing area of the sealring rib is larger than the cross section of the adjoining pipe it becomes impossible to over compress the sealring within the G-LOK ® connector. For normal piping applications, the compressive limits are governed by other factors such as piping flexibility analysis or anchor loads and in practice the G-LOK ® connector will always perform under the applied compressive loading.
Thermal Shock G-LOK ® connectors have been applied to both Cryogenic and high temperature service which are subject to thermal transient conditions. For very severe thermal shock (i.e. quenching), the connectors can be provided with thermal shrouds to protect the sealring lips from the full effects of the thermal shock.
QUALITY ASSURANCE GALPERTI ENGINEERING has been successfully audited and awarded the prestigious BS EN ISO 9001 accreditation for its thorough Quality Assurance Programme. This ensures strict compliance with all relevant Regulatory Specifications and codes including ANSI, API, ASME, BS, NACE. Material specifications to ASTM and BS are adhered to, and full traceability of all components is assured. Using the latest CNC machine tools in a modern factory environment, manufacture is carried out in accordance with all current specification. G-LOK ® connectors, in addition to meeting the current Industry Standards for Interchangeability, can be supplied in accordance with various design codes/regulations including: x ANSI/ASME x API x BS 5500 x UK Offshore Regulations x Customers’ special requirements x Country Codes
TYPE APPROVAL TESTING The G-LOK ® range of connectors has been subjected to extensive strain gauge and destructive testing and has been awarded full design approval by Lloyd’s Register.
