Product description
Gost PN25 12821-80 welding neck flange
The welding neck flange refers to a kind of flange with cone neck and butt welding with cylinder or pipe, which belongs to integral flange. 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. The WN flange is suitable for occasions with high pressure, high temperature or high sealing requirements.
Butt welding flange with neck is a kind of excellent engineering component. It is often used in the occasion of high requirement of pipeline medium. The butt welding and flat welding process we used is mainly used to improve the welding stress of welding junction and reduce the deformation of sealing surface. However, the cost of raw materials used in the neck butt welding flange is higher, and the pressure of flat welding flange with neck is lower than that of butt welding flange.
