Product Families

Weld Neck Flanges

Flanges with a tapered hub that is butt-welded to pipe or equipment, transferring stress smoothly into the line and providing a high-integrity connection for wellhead piping and adapter spools.

Blind Flanges

Solid flanges with no bore used to close off a flanged outlet, valve, or vessel; on wellheads they cap unused outlets and provide isolation for pressure testing or future tie-ins.

Adapter Flanges

Flanges machined with different connections, bores, or pressure ratings on each end to mate dissimilar wellhead equipment, such as crossing between two flange sizes or API rating classes.

Double Studded Adapters (DSA)

Spool-type adapters with studded (tapped) flange faces on both ends, used to stack or convert between two different flanged connections without an intervening pipe section.

Hanger / Tubing Head Flanges

Flanged bodies that land and support casing or tubing hangers, transferring the weight of the suspended string to the wellhead while sealing around the hanger.

Companion / Studded Flanges

Matched pairs of flanges joined by full-length studs and nuts (companion) or tapped studded faces (studded outlet) used to bolt valves, chokes, and spools into the wellhead stack.

Test Flanges

Flanges fitted with test ports or gauge connections used to apply and monitor hydrostatic or gas pressure when verifying seals on the wellhead assembly.
