1. Introduction: Welding Neck Flanges are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.
2. Description: WN flange is suitable for occasions with high pressure, high temperature or high sealing requirements. The WN flange refers to a kind of flange with cone neck and butt welding with cylinder or pipe, which belongs to integral flange. Butt welding flange is not easy to deform and well sealed. It is used in many industries with reasonable rigidity and elasticity. The neck butt welding flange is a bell shaped structure and is used in pipelines with large fluctuation of pressure or temperature. Due to the transition structure of the conical neck and the butt welding connection, the strength and rigidity of the flange are strengthened, and the sealing is better than the flat welded flange.
