Product Description

A flange is a method of connecting pipes,valves,pimps,and other equipment to form a pipework system .It also provides easy access for cleaning ,inspection or modification.
Flange are usually welded or screwed into such systems and then joined with bolts.

Weld Neck
This flange is circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography .the bores of both pipe and flange match ,which reduces trubulence and erosion inside the pipeline.the welded neck is therefore favoured in critical applications.
