How does flange connection work?

A flange connection involves two pieces of equipment, pipes, two flanges, flange mats, and bolts. Force must be exerted to form a seal, often using a gasket between flange faces secured by bolts.

What standards do your flanges comply with?

Our flanges comply with multiple standards including GOST 12820-80, ANSI B16.5, EN1092, BS4504, JIS B2220-2012, DIN, and AMSE B16.5.

What materials are available for the flanges?

We offer Stainless Steel (e.g., 304, 316L), Carbon Steel, Duplex Stainless Steel, and Pipeline Steel options.
