Stainless steel socket welding flange refers to the flange where the end of the pipe is inserted into the flange ring step, and the pipe end and the outside are welded. There are two types with neck and without neck. The flange with neck tube has good rigidity, small welding deformation and good sealing performance. It can be used in 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 in occasions with higher sealing requirements. When designing, the socket welding flange can be checked according to the integral flange.Material:
