Chamunda Industries is a leading manufacturer and exporter of Weld Neck Flanges that are being designed as per the national and international standard quality of raw materials and thus making sure of their durability and high quality. Weld Neck Flanges have a long tapered hub and gradual transition of thickness in the region of the butt weld joining them to the pipe. The tapered hub provides important reinforcement to the flange and resistance to dishing. These flanges are being supplied in the course of suitable test certificates of standard raw materials and finished products.
Our Weld Neck Flanges can further be customized in terms of thicknesses, sizes and specifications as per the specific requirements of our clients. This type of flange is preferred for severe service conditions resulting from high pressure, sub-zero or high temperatures. We offer these flanges at market leading prices.
