Socket-weld Steel Pipe Flange

Socket Weld Flange

Our socket welding flange is designed for pipelines with small diameter and high working pressure. Generally, the diameter is not greater than 40mm and the working pressure shouldn't exceed 10.0Mpa. The production process of the socket welding flange is similar to that of loose flange. One end of the flange is welded together with pipe, while the other end is connected through thread.
