Product description

Stainless steel neck flanges 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.
