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 Stainless Steel (304, 316, etc.), Carbon Steel, Duplex Stainless Steel, and Pipeline Steel, among others.

What is the minimum order quantity (MOQ)?

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