Neck butt welding flange refers to a kind of flange with cone neck and butt welding with cylinder or pipe. It is an integral flange.
Because of the transition structure and butt welding connection of the conical neck, the strength and rigidity of the flange are strengthened, and the sealing performance is better than that of the flat welding flange.
It is suitable for high pressure, high temperature or high sealing requirements.
