U-Ideal Weld Neck flanges attach by welding the pipe to the neck of the flange.
This transfers stress from the flange to the pipe instead. It also reduces the stress concentration from the base of the hub. Weld neck flanges are often used for applications where high pressure is a factor. The inside diameter of the flange is designed to match the pipe's inside diameter. Weld Neck Pipe flanges with a hub have published specifications that range from 1/2" thru 96". Our company provides these in all material grades, specifications and sizes.
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" for weld neck pipe flanges under 400#. For weld neck pipe flanges of 400# and up, the standard weld neck pipe flange raised face height is 1/4".
