WELDING NECK RISE FACE FLANGE（WNRF）

Stainless steel weld neck flange are popularly used in excessive stress applications, with their capability to provide assisting power along with stress distribution. Weld neck flanges are circumferentially welded at the neck where the integrity of the butt welded location can be without problems examined by means of radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inner the pipeline. The weld neck is consequently durable in fundamental applications.
