A182 Stainless Steel Flanges Production Range & Specificatio

ASTM A182 F304 Stainless Steel Weld Neck Flanges

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 manufacturing these Weld Neck flanges 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".
