Weld neck flanges are used for a wide variety of applications which are easily identified by their long, tapered neck. The tapered neck of the weld neck flange offers strength reinforcement and support of the flange and pipe. Another feature of the weld neck flange is that the inside diameter of the flange matches that of your pipe.
The weld neck flange's tapered neck makes it ideal for use in high-pressure situations and is, in fact, the most commonly used flange for high-pressure applications. weld neck flanges are also requested for use in extremely high or low temperature conditions. Customers may specify weld neck length if required. No matter what size pipe you have, or material you need, we have the right weld neck flange for you.
