Stainless Steel Socket Welding Flange (SW)
Material : Stainless Steel 304 or 316L
Size : DN15 -DN600
Connection : Weld
100% tested and inspected
The Stainless Steel Socket Welding Flange (SW) is designed for small-diameter, high-pressure piping systems.
The pipe is inserted into the flange socket and then fillet welded around the hub, creating a strong and reliable connection.smooth surface finishing, and strict quality inspection to ensure reliable performance and long service life.
Working Principle of Socket Welding Flange
The flange is then bolted to another flange with bolts, nuts, and a gasket to create a secure and leak-proof piping connection.
