The weld neck flange, abbreviated as WNF, is a flange type that is usually used with pipes, as contrasting to pressure vessels. The design of the flange permits for a full penetration weld at its base where it attaches to the pipe. This weld can be X-ray inspected for quality control.
The weld neck flange comes in two types, regular and long. The hub of the weld neck is calculated to reduce the stress at the base of the flange. Regular weld neck flanges are used with buttweld fittings and connecting two pieces of pipe composed. Long weld neck flanges are usually used with apparatus and vessel nozzles. A long weld neck flange is rarely used with the pipe.
Both types of flanges are bored to tie the inside diameter of the pipe or fitting to which it will be welded to. However, if the bore does not match, the inner width can be ground out to match the greater bore pipe. Weld neck flanges are appropriate where high pressure, extreme temperatures, shear influence and vibratory stresses apply.
