JIZHONG(G)Welded Neck Flange is flange that is designed to be joined to a piping system by butt welding. This kind of flange includes lots of specifications.

Weld Neck Flange is expensive because of its long neck and the cost of people to contact WN flange with pipeline or fitting but is preferred for high-stress applications. The necks, or hubs, transmit stresses to the pipeline.

The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the Weld Neck Flange. The Weld-Neck flange bore matches the pipeline, reducing turbulence and erosion.

Product Name: Weld neck flange

Product Number: NO248

The flange is the part for connecting pipe and pipe at pipe end. There are holes on the flange, use bolt to connect two flanges, and use gasket to seal two flanges.
