Weld Neck Flanges

Weld-Neck flanges or welding-neck flanges can be differentiated from all other types of flange by their long tapered hub. In addition, there is also a gentle transition of thickness in the region of the butt weld that joins them to pipe or a fitting. Weld-Neck flanges or welding-neck flanges are best suited for severe service conditions, whether loading conditions are substantially constant or fluctuate between wide limits.

We are manufacturing a comprehensive range of Weld Neck Flanges which are available in various sizes and dimensions to match the pipes. These flanges are mainly used to connect pipes and are considered as an important unit to hold up mechanical parts. Our Weld Neck Flanges are developed from superior quality carbon steel, stainless steel and alloy steel, and are built in compliance with client's requirements.
