Product Description

Banking on our 3 decades of industrial experiences, we have been manufacturing and exporting an innovative range of Weld Neck Flange. These flanges are designed at our state of the art machining facility using top quality materials, as per the standards laid down by regulatory bodies. Our Weld Neck Flange is welded to the end of a piping system to transfer stress to the pipe. We lay prime emphasis on the packaging of these flanges to ensure safe transit at clients’ end.

Features:

  • High impact strength
