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 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 is the minimum order quantity (MOQ)?

For normal and standard products, the MOQ can be as low as 1 piece.
