Welding neck flanges are commonly referred to as high hub flanges. It is designed to transfer stress to the pipe, reducing the high stress concentrations at the base of the flange.

A weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange. There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant. A weld neck flange consists of a circular fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt welded to a pipe. Weld Neck Flanges have a long tapered hub and are often used for high pressure applications. These flanges are designed to be joined to a Piping system by But Welding.

The inside diameter of the flange is designed to match the inside diameter of the pipe. The neck solder pipe flanges with a hub have published specifications that range from 1/2 "to 96". Our company provides these products in all categories of materials, specifications and sizes.

Welding neck pipe flanges are generally provided with a raised face, flat face or RTJ coating. When a raised face is required for weld neck pipe flanges, the standard height is 1/16 " for weld neck pipe flanges of more than or equal to 400#. For weld neck pipe flanges of 400# and up, the standard weld neck pipe flange raised face height is 1/4".
