SS 316L Socket Weld Flanges

The SS 316L Socket Weld Flange (SW) is a forging characterized by a recessed area (socket) into which the pipe is inserted. The pipe is then secured with a single fillet weld outside the flange. This design is highly effective for smaller bore piping (typically NPS 4 and smaller) in high-pressure, low-temperature, non-critical services. The recessed pipe end also simplifies alignment and provides a smooth inner bore, crucial for flow integrity. The 316L designation ensures a low carbon content, which is vital for preventing sensitization and the resulting intergranular corrosion in the weld zone, which is particularly relevant for the single, external fillet weld. The presence of Molybdenum guarantees superior defense against pitting and crevice corrosion in severe, chloride-rich environments. Zeron Fasteners manufactures and supplies robust SS 316L Socket Weld Flanges conforming to high-pressure standards like ASME B16.5 and ASTM A182 F316L, offering a strong and reliable alternative to threaded connections.
