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.
This is designed to be joined to a piping system by buttwelding. It is relatively expensive because of Its long neck, but is preferred for high stress applications. The neck, or hub transmits stresses to the the base of the hub to the wall thickness at the butt weld, provide important reinforcement of the flange. The bore of the flange matches the bore of the pipe, reducing turbulence and erosion.
Keeping in view industry requirements we manufacture Weld Neck Flange with the finest quality material. Weld neck Flange is drilled with the wall thickness of the flange having the same dimensions of the matching pipe.
