  Weld-Neck flanges or welding-neck flanges can be differentiated from all other types of flange by their long neck. The weld neck flange is so named because its neck part of the flange is welded to the end of a piping system. Weld neck flange is designed to transfer stress to the pipe in the purpose of reducing high stress concentrations at the base of the flange. Normally Weld neck flange is expensive because welding neck flange use more material than other flanges due to it's long neck.
