Weld Neck Flanges

Backed by a team of professionals, we are engaged in offering a wide range ofWeld Neck Flanges to our esteemed clients. This is designed to be joined to a piping system by butt welding. Weld neck flanges are circumferentially welded at the neck where the integrity of the butt welded area can be easily examined by radiography. Welding Neck Flanges are easy to recognize at the long tapered hub that goes gradually over to the wall thickness from a pipe or fitting. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications.
