Detailed explanation of the way of connecting pipes with stainless steel flanges

Stainless steel flange is often used in pipeline engineering. The material is generally high in hardness and is mostly formed by quenching, so the toughness is general, so it is suitable to be used in pipeline application. The core hardness of stainless steel flange is generally only more than 30 degrees. Under normal circumstances, stainless steel flange will be quenched, because its chromium content is 0.1% ~ 0.5% (stainless steel flange generally does not contain chromium), The carbon content is below 1.0%, and the stainless steel flange is made of high-temperature stainless steel. Although the surface hardness (HRC) of some stainless steel flanges can reach ≥ 56 (the hardenable layer is only about 15mm).

Stainless steel flange connection is to fix two pipes, pipe fittings or equipment on a flange respectively, add flange pads between the two flanges, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flanges, which also belong to flange connection.

Stainless steel flange connection is an important connection mode in pipeline construction. Stainless steel flange connection is convenient to use and can bear large pressure. In industrial pipelines, stamping elbows connected by stainless steel flanges are used. In the family, the pipe diameter is small, and it is low-pressure, so the flange connection can not be seen. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.

Stainless steel flange fittings also have high requirements for welding rods for welding flanges. It is used in chemical industry, chemical fertilizer, petroleum and machinery manufacturing.
