Stainless steel flange is a kind of pipe flange made of stainless plate. As we know stainless steel is usually divided into 304, 304L, 316, 321, 316L and others. So, SS pipe flange can be also classified into these types based on different stainless material. Flange stainless is often divided into threaded (wire) flange and welding flange. SS blind flange is mainly used in chemical equipment, pressure vessels, pipeline engineering.

SS flange specification: 1/2 ″ ~ 80 ″ (DN10-DN5000)

Stainless flange pressure level: 0.25Mpa to 250Mpa (150Lb to 2500Lb)
