Weldneck Flanges

These are the most common type of flanges used for high-pressure application.It is designed to transfer stresses concentrations of the base of the flanges. These are recognized by their long tapered hub. The hub provides an important reinforcement to the flange itself and acts to reduce rotation of the flange at bolt up. The smooth transition between flange and the hub combinbed with the strength of the butt weld joint, allows the flanges to be used in extreme conditions of cyclic loading, bendng and temperature fluctuations.
