‘GOLDEN LOCK’

THE “FOURWENTS” GOLDEN-LOCK CLAMP CONNECTOR
IS A RELIABLE AND SMALL 4-BOLT FITTING THAT WAS CREATED AS A
HIGH-PERFORMANCE SUBSTITUTE FOR FLANGES.

  • For use in piping systems needing high integrity seals in applications involving corrosive, erosive, high temperature, high pressure, and cyclic environments, the “FOURWENTS” Golden-Lock clamp connection is a dependable, simple-toassemble, metal-to-metal sealed connector. It is designed to work with compressors, pumps, manifolds, valves, pressure vessel nozzles, and closures.
  • The clamp joint is constructed using two clamps, two hubs, one seal ring, four studs, and eight nuts.
  • The hub sealing surface is interfaced with a reusable, zero leakage seal ring to provide high integrity and a strong seal. In order to provide a self-energized seal during operation, the joint conguration makes sure that the seal ring is elastically loaded during assembly.
  • To t any application, “Fourwents” Oil & Gas Technologies will custom create and optimise unique Golden-Lock products.

HOW THE WORKS ‘FOURWENTS’ ‘GOLDEN LOCK’ CLAMP CONNECTOR.

Fourwents GOLDEN LOCK is a fourbolt pipe clamp connection with two butt weld hubs welded to connecting pipes, two clamps (180º segments) spun around the hubs, and a sealing ring that ts between the hubs.

The bolt set includes four studs and four spherically facing nuts that secure the clamps over the hubs and engage the assembly.

Fourwents ‘GOLDEN LOCK’ is a unique pipe clamp connector with quick connect and disconnect capabilities. It is suited for applications requiring space, weight, and joint integrity. GOLDEN LOCK outperforms ANSI and DIN anges due to its greater characteristics.

The ‘GOLDEN LOCK’ pipe clamp connections are interchangeable with any other type connectors.

Fourwents ‘GOLDEN LOCK’ is compliant with ASME Section III, Class 1, 2, 3, 6, CSA Can 3 N285.0, and ASME Section VIII division 1 & 2.

FOURWENTS 'GOLDEN LOCK'
SAVES WEIGHT AND SPACE.

The ‘Golden Lock’ connector offers the chance to build lightweight, compact systems since it is substantially lighter and smaller than an equivalently rated ANSI or API ring joint ange connector. The clamp fully rotates around the hub, making it simple for position the pipes and hookups. SHORTER LENGTH, SMALLER DIAMETER, NO BOLT HOLES TO LINE UP.

THE ‘FOURWENTS’ METAL-TO-METAL ‘CLAMP CONNECTOR SEALS’

The rib of the seal ring is clamped between the hub faces. The lips of the seal ring engage the inner hub surface in an interference t, Which deects the lips to form a seal.

TWO HUBS

The clamp secures the two hubs against the seal ring ribs. The clamp assembly draws the hubs together, causing the seal ring lips to deect against the hubs' inner sealing surfaces. This deection elastically loads the lip of the seal ring against the hub's inner sealing surface, resulting in a self-energized seal.

METAL SEAL RING

A seal ring's cross section is shaped like a "T". As the connection is created, the legs of the "T" form a rib that is supported by the hub faces. Two arms form a lip seal on the hub's inner surface, which serves as the sealing surface. Internal pressure helps to reinforce the seal.

CLAMP ASSEMBLY

Designed for almost 360° clamping contact with the hubs. A relief notch in the clamp segments allows for uniform distribution of makeup forces.
There is no need for a certain orientation when installation.

THE ADVANTAGES OF FOURWENTS 'GOLDEN LOCK'
PIPE CLAMP CONNECTORS.

  • EASIER TO CONSTRUCT AND INSTALL BECAUSE THERE ARE NO BOLT HOLES TO LINE UP.
  • INSTEAD OF UP TO 24 BOLTS ON AN ANSI FLANGE, THERE ARE JUST 4 TO TIGHTEN.
  • TURNING THE GOLDEN LOCK AROUND THE HUB MAKES IT SIMPLE TO ALIGN AND TIGHTEN THE BOLTS.
  • REDUCED MAINTENANCE DOWNTIME IS ACHIEVED WITH FASTER AND SIMPLER MAKEUP AND BREAKOUT PROCESSES.
  • REDUCED BOLT TORQUE: NORMALLY 50% LESS THAN A RING JOINT FLANGE'S TORQUE.
  • BOLT OVER-TENSION HAS NO EFFECT ON SEALING INTEGRITY.
  • SIGNIFICANTLY SMALLER AND UP TO 75% LIGHTER THAN ANSI FLANGES.
  • 40% SHORTER CONNECTION LENGTH AND 25% SMALLER CLAMP DIAMETER.
  • THE GOLDEN LOCK MAY BE INSTALLED AND REMOVED IN THE SAME TIME IT TAKES TO CONNECT A SINGLE ANSI FLANGE.
  • ONCE IN SERVICE, BOLTS ARE USUALLY NOT REQUIRED TO BE RE-TIGHTENED.
  • ONE CLAMP SIZE WILL BE REQUIRED FOR EACH NOMINAL PIPE SIZE.
  • PROCESS PIPING SYSTEMS
  • GREATER FLEXIBILITY IS PROVIDED BY REUSABLE SEAL RINGS FOR HYDRO-TESTING AND COMMISSIONING BEFORE SERVICE.

THE PIPE CAN WITHSTAND TENSION, BENDING AND COMPRESSION
WITH FOURWENTS 'GOLDEN LOCK' CONNECTORS.

The Forwents 'Golden Lock' connector operates better when constructed of the same material as the pipe and a majority of other components that may be connected.

The rib of the seal ring keeps the seal lip from being crushed by over-tightening. The rib serves as a positive stop during makeup, but it also distributes compressive and bending loads from one hub member to another. The rib bearing area is large enough to support the most severe loading that a piping system can sustain.

TENSION, COMPRESSION & BENDING

TENSION :

  • Supports higher tensile stresses than traditional ANSI anges.
  • Can resist higher strain loads than the pipe itself.
  • In destructive tests, the pipe can be loaded to failure without leaking the Golden Lock connector.

COMPRESSION :

  • In conventional piping applications, the ‘Golden Lock’ connector or seal ring cannot be overloaded during compression.
  • For high compressive loads, the connector's maximum load is dened by the pipe limit.

BENDING:

  • Independent tests have demonstrated that ‘Golden Lock’ connectors can endure high bending strains without leaking or loosening.

SERVICE EXTREMES

‘FOURWENTS’ ‘GOLDEN LOCK’ CONNECTORS CAN EXPERIENCE VIBRATION, HEAT, COLD, AND THERMAL SHOCK DURING HEAVYDUTY USE. GOLDEN LOCK CONNECTORS REGULARLY WITHSTAND HARSH CONDITIONS WITHOUT REQUIRING ROUTINE MAINTENANCE. SPECIAL DESIGNS ENABLE MAINTENANCE-FREE SERVICE EVEN IN THE HARSH CONDITIONS SHOWN IN THE TABLE.

Examples of ‘Fourwents Golden lock’connector applications in extreme service circumstances.

  • Vibration: 80 to 200 cycles per second under 6,600 PSI
  • High Temperature: Service experience to 1700° F.
  • Low Temperature: Routine liquified gas service including liquid hydrogen and nitrogen to -425° F.
  • Thermal Shock: Routine service with temperature changes up to 300° F. per hour.
