Weld Neck Flange

We are leading manufacturer and stockist of Weld Neck Flange in China.Weld neck pipe flanges attach to the pipe by welding the pipe to the neck of the pipe flange. The Weld Neck Flange allows for the transfer of stress from the weld neck pipe flanges to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck flanges are often used for high pressure applications. The inside diameter of a weld neck flange is machined to match the inside diameter of the pipe. The Weld Neck flange with a hub have published specifications that range from 1/2" thru 80".
