A105N RF Welding Neck Flange, Forged, DN50, SCH 160, CL150, Galvanized, Pipe Connection.
Neck butt welding flange is a flange with conical neck and butt welding with cylinder or pipe. It belongs to integral flange. [1]
Because of the transition structure of cone neck and butt welding connection, the strength and stiffness of flange are strengthened, and the sealing property is better than that of flat welding flange. The disadvantage is to use forgings to manufacture, cost more materials, manufacturing costs. Suitable for high pressure, temperature or sealing requirements.
