Welding neck flange
It is a type of tube fittings and it is refers to a flange with a neck that has a transition of a round pipe, welding neck flange connect with pipe for butt welded . meanwhile, Butt welding flange is not easy to be deformed, sealed, it is widely used for construction,it has rigidity and elasticity requirements and reasonable butt welding thinning transition, the welding joint be away from the joint surface, in addition, the joint surface be free from welding temperature deformation.

The advantage of welding neck flange
The sealing performance is better than that of the Slip on welding flange.,and it can applied in high temperature and pressure work situation,so it Suitable for applied in where pressure, temperature is high or where sealing is required. it widely used in Boiler pressure vessel, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbow food and other industries
Disadvantage
It needs to be manufactured with forgings, which consumes a lot of materials and has a large manufacturing cost.
