D J Metal Industries specializes in the production of high-quality Stainless Steel weld neck flanges conforming to ANSI/DIN/BS standards in India. Our prompt delivery programs include standard sizes for stainless steel weld neck flanges. The connection of weld neck pipe flanges to the pipe involves welding the pipe to the neck, effectively transferring stress from the weld neck to the pipe itself. This method also mitigates high stress concentration at the base of the hub of the weld neck pipe flanges. Widely employed in high-pressure applications where extreme temperatures prevail, stainless steel weld neck pipe flanges are designed to match the inside diameter of the pipe through precision machining.

Stainless Steel Long Weld Neck Flanges can be readily identified by their elongated tapered hub, which serves as a transition from the integral flange thickness to the thickness of the pipe or fitting. This taper proves advantageous in mitigating the effects of line expansion or other variable forces on the Weld Neck Flange. These ss flanges undergo boring to align with the inside diameter of the corresponding pipe or fitting end, eliminating any hindrance to product flow. This proactive measure prevents turbulence at the joint and minimizes erosion during the transition. Additionally, the SS Long Weld Neck flanges ensure optimal stress distribution through the extended hub and are easily subjected to radiographic examination for flaw detection. The connection of the Long Weld Neck flange type involves welding to a pipe or fitting with a single full penetration V weld (Buttweld).
