SS 304L Socket Weld Flanges - High Pressure & Small Bore

The SS 304L Socket Weld Flange (SW Flange) is a specialty pipe component primarily used in small bore (NPS 4 and smaller), high-pressure piping systems. The flange features a shoulder or socket on the inside bore into which the pipe is inserted. The connection is then completed by a single fillet weld on the outside of the flange. This design offers high internal strength and prevents the need for beveling the pipe end. The use of the low-carbon 'L' grade stainless steel is paramount, as it minimizes the risk of carbide precipitation during the welding process, thereby preserving the material's excellent corrosion resistance properties. Zeron Fasteners manufactures and supplies high-quality SS 304L Socket Weld Flanges that comply with ASME B16.5 standards, making them highly reliable for process piping in chemical, hydraulic, and steam service lines.
