304 Stainless Steel Socket weld Flanges are flanges where the end of the pipe is inserted into the flange ring step, and the pipe end and the outside are welded. They are made of high-quality 304 stainless steel, which is a type of austenitic stainless steel with excellent corrosion resistance, heat resistance, and low-temperature strength. 304 stainless steel is widely used in various industries such as food processing, chemical processing, and pharmaceuticals, making it an ideal material for flange pipe fittings.

These flanges come in two types: with necks and without necks. The flange with neck tube has good rigidity, a small welding deformation, and good sealing performance. It can be used on occasions with a pressure of 1.0 to 10.0 MPa. Type B flanges for vessels also belong to socket welding flanges, which are used on occasions with higher sealing requirements. When designing, the socket welding flange can be checked according to the integral flange.
