Product Description

          Butt welding flange with neck is a kind of flange with conical neck and butt welding with cylinder or pipe. It belongs to integral flange. Due to the transition structure of conical neck and butt welding connection, the strength and stiffness of flange are strengthened, and the sealing property of flange is better than that of flat welding flange. The disadvantage is that it needs to be manufactured with forgings, which consumes a lot of materials and costs a lot of manufacturing costs. Suitable for high pressure, high temperature or high sealing requirements.
