Grayloc: the pipe connection for high pressure and high temperature applications

Grayloc is the alternative to the use of heavy flanges and comes into its own in extreme conditions. Want to save weight and space? High pressure and high temperatures? With these connectors will ensure 100% helium-tight metal to metal seals, even under exceptional conditions.

Grayloc is considered the standard in the oil and gas extraction, and petrochemical industries. With over fifty years of experience, Grayloc is a reliable and safe choice!

How does it work?

A Grayloc connection consists of four components: a seal ring, two hubs, two clamp segments and four sets of studs & nuts. The hubs are welded to the pipe ends. Next, the seal ring is placed between the hubs and the connection is completed with the clamps and studs & nuts.

What makes the Grayloc connection so efficient?

  • More compact than traditional flanges
  • Less weight than traditional flanges.
  • Always only 4 studs and 8 nuts required.
  • Reduced maintenance costs
  • 360-degree rotation, no alignment required.
