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. Hub sealing surfaces must be clean prior to being placed in the furnace.
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.
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 a grayloc connector used for?
DESCRIPTION The Grayloc® Connector has been a fieldproven and reliable mechanical connector for over 50 years. This connector features a metal-to-metal bore seal that is recognized as the standard for critical service piping and vessel connections. Grayloc® connectors save weight, space, and fabrication time.
