Stainless Steel Socket Welded Flanges (SW Flanges) are designed with a recessed socket that allows the pipe to be inserted into the flange before welding. The connection is completed with a fillet weld around the outer edge.
These flanges are widely used in small-diameter, high-pressure piping systems, where precise alignment and leak-tight performance are required. Manufactured from stainless steel, they offer excellent resistance to corrosion, oxidation, and aggressive media, making them suitable for harsh and hygienic environments.
