What Is Weld Neck Flange?

A weld neck flange is a type of pipe flange designed with a long, tapered neck that is welded to the pipe, providing a strong and secure connection for high-pressure and high-temperature applications. A weld neck flange often features a raised face to ensure a secure and leak-resistant connection. Weld neck pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for weld neck pipe flanges, the standard height is 1/16 inch for weld neck pipe flanges fewer than 400#. For weld neck pipe flanges of 400# and up, the standard weld neck pipe flange raised face height is 1/4 inch.
