Three Standard Systems

Flanges to ANSI B16.5 (1/2-24 inch, 150-2500LB), JIS B2220 (10A-1500A, 1K-30K) and BS4504 (DN10-DN2000, PN6-PN40) cover the standard pressure systems used across global projects.

Types and Materials

Welding neck, slip-on, blind, lap joint, threaded and socket-weld types in carbon steel (A105, A694 F42-F70, A350 LF1/LF2), stainless (A182 F304/304L, F316/316L, F321) and alloy (F11/F12/F22).

Matched With Pipe Supply

Ordering flanges together with pipe and fittings from one source keeps pressure classes, facing finishes and bore schedules aligned - and one inspection covers the whole spool package.
