Copper Nickel Weld Neck Flange

attach by welding the pipe to the neck of the flange. This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Weld neck flanges are often used for applications where high pressure is a factor. The inside diameter of the flange is designed to match the pipe’s inside diameter. Weld Neck Pipe flanges with a hub have published specifications that range from 1/2″ thru 24″.
