Concept of  WN flanges

Welding neck Flanges  are a kind of parts that are widely used in engineering design and involve a wide range of areas. The distance between the welding port and the joint surface is large, and the joint surface will not be deformed due to the welding temperature, so it is currently widely used in the welding of pipelines. Butt welding flanges are generally suitable for pipelines with large fluctuations in pressure or temperature, as well as pipelines with high temperature, high pressure and low temperature, and also suitable for pipelines that transport expensive, flammable and explosive media.
