Plate flat welding flange

Overview:

Plate type flat welding flange is a common type of flat welding flange. The structure of the plate type flat welding flange is relatively simple, usually consisting of a circular flange plate and several bolt holes. There is a through hole at the center of the flange that matches the outer diameter of the pipe. After the pipe is inserted into this through hole, welding is carried out between the flange and the outer wall of the pipe. Its sealing surface is generally flat or raised. Flat sealing surfaces are suitable for occasions with lower pressure and cleaner medium, while raised sealing surfaces can provide better sealing performance and are suitable for situations with slightly higher pressure.
