Stainless Steel Socket Weld Flanges Manufacturer and Supplier In India

Stainless steel socket weld flanges are a type of pipe flange used in piping systems for attaching pipes or fittings to a pipeline. These flanges have a socket or recess with an internal shoulder that adjusted the pipe's end, allowing for a safe and leak-free connection. Stainless steel socket weld flanges are commonly made from stainless steel materials known for their excellent corrosion resistance and durability. They are characterized by a circular recess or socket on the inner side of the flange, which matches the outer diameter of the pipe to be attached. The pipe is inserted into this socket, and then fillet welds are applied to secure the connection. The applications are high-pressure piping systems, shipbuilding, fire protection systems, HVAC systems and many more.
