What are Stainless Steel Weld Neck Flanges?

A Stainless Steel Weld Neck Flange is a type of pipe flange designed with a long tapered hub that gradually transfers stress from the flange to the connected pipe. The flange is butt-welded to the pipe, providing a strong and leak-proof connection capable of handling high-pressure and high-temperature applications.

The long neck design significantly reduces stress concentration and improves structural integrity, making weld neck flanges the preferred choice for critical industrial piping systems.
