Weld neck flange is the most widely used type in process piping, it is designed to be connected by a butt weld connection to the pipe. Weld neck flanges are used in high-pressure and temperature applications. Weld neck flange typically have a raised or flat surface. At ASME/ANSIB 16.5 flange, the standard height of raised face is 0.06″ (1.6mm) for WN flanges under class 400#, if the class of WN flange is 400# and up, the height of raised face will be 0.25″ (6.4mm).
