How does a flange connection work?

A flange connection joins two pieces of equipment or pipes using two flanges, bolts, and a gasket. Force is exerted to compress the gasket, forming a tight seal between the flange faces.

What materials are available for the flanges?

We offer various materials including Stainless Steel (304, 316L, Duplex), Carbon Steel, Pipeline Steel, and others like A182F304/304L and UNS32760.

What standards do your flanges comply with?

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