With a neck on one side of the flange, the other side of the flange is sealing face, which are between the two flanges joint. WN flange usually supplied with flat face (FF), raised face(RF) and ring type joint (RTJ).

Product Details

        The weld neck flange is suitable to used for high pressure, high temperature, low temperature situation because of the butt welding connection method.

The weld neck flange has a good excellent stress distribution by its tapered neck .

         The butt welding joint can be inspected easily ,for example the radiography testing. Our weld neck flanges feature high strength,good toughness,and high reistance to corrosion,high pressure and temperature.The raw materials of them come into carbon steel,stainless steel,alloy steel,low temperature steel and high performance steel.Also,we can provide customized flanges according to customers'requirements.

         Weld-Neck flanges or welding-neck flanges can be differentiated from all other types of flange by their long tapered hub.

         The Welding neck flanges is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange.
