Stainless steel welding neck flanges are widely used in industries. Welding neck flanges are not easy for deformation, having good sealing and wide application. Welded junction is far from mating face in case of deformation on mating face because of welding temperature. The flanges adopt complicated horn structure. Welding neck flanges are suitable for the pipe having widely fluctuating pressure or temperature or high pressure high temperature pipe. They can be used for transmitting inflammable or explosive medium.
