SS 304 Socket Weld Flanges

SS 304 Socket Weld Flanges (SW Flanges) are specialized pipe fittings primarily used in small-bore, high-pressure piping systems. They are designed with a counterbore (socket) into which the pipe is inserted before being secured with a single fillet weld on the outside circumference. This design makes installation easy while providing the structural strength necessary for demanding services. Manufactured via forging, the SS 304 material ensures excellent general corrosion resistance to water, steam, and a range of mild chemicals, making them popular in systems transporting non-lethal, non-cyclic fluids. Key applications include chemical processing, hydraulic lines, instrument air lines, and small-diameter utility systems. Zeron Fasteners manufactures and supplies high-quality SS 304 socket weld flanges, guaranteeing conformance to ASME B16.5 and ASTM A182 standards for reliable, high-integrity joints.
