Overview of Stainless Steel Weld Neck Flange
A Stainless Steel Weld Neck Flange is a type of pipe flange designed for high-pressure and high-temperature applications, featuring a long tapered hub that is welded to the pipe. This hub provides reinforcement and helps to distribute stress evenly, making the weld neck flange one of the strongest and most durable flange types available. The flange itself has a circular shape with bolt holes around its perimeter, allowing it to be securely bolted to a matching flange with a gasket in between to ensure a tight, leak-proof seal.
