What is a Grayloc flange?
Grayloc® compact flanges (GCFs) incorporate our proven metal-to-metal technology into a bolted flange design. Including the Grayloc seal ring in a compact flange design provides a solution with significant space and weight savings that outperforms conventional flanges.
What is Grayloc connection?
The Grayloc connector provides a highly reliable metal-to-metal seal that is both self- energized and pressure-energized. A complete Grayloc connector consists of two hubs, one seal ring, one set of clamps, stud bolts, and spherical-faced nuts.
How does a Grayloc work?
The metal Grayloc® seal ring consists of a rib and two lips. During makeup, the seal ring lips deflect inward as the connector is assembled. This deflection is controlled and is within the elastic limits of the seal ring material. Two Hubs—The clamp fits over the two hubs and forces them against the seal ring rib.
What is compact flange?
A compact flange, similar to a swivel ring flange, is a two-piece constructed flange used extensively for offshore pipelines, offshore industry applications and onshore and sub-sea applications. Its double sealing action prevents hydrocarbon releases to address health and safety issues and concerns.
