Socket welding flange

The socket welding flange refers to the flange that is inserted into the flange ring step at the end of the pipe welded at the end of the pipe the outside. There are two types of necked non-necked. The flange with neck tube has good rigidity, small welding deformation good sealing performance. It can be used in the pressure of 1.0 ~ 10.0MPa. Type B flanges for containers are also socket-welded flanges are used in applications with high sealing requirements. When designing, the socket welding flange can be checked as an integral flange.
