SS 420 Socket Weld Flanges

The SS 420 Socket Weld Flange (SW Flange) is a highly specialized forging component designed primarily for small-bore piping (typically NPS 4 or smaller). It features a recessed area (socket) into which the pipe is inserted before being secured with a single fillet weld on the outside. This design provides excellent strength and is preferred in high-pressure and high-temperature systems where leak integrity is paramount. Manufactured from Martensitic Grade 420 Stainless Steel, these flanges are chosen for their superior hardness and wear resistance, properties significantly enhanced by heat treatment. Zeron Fasteners produces these flanges using reliable forging techniques, ensuring maximum material density and structural integrity required for critical service applications. SS 420 Socket Weld Flanges are widely used in chemical processing, hydraulic systems, and steam lines where their ease of alignment and structural strength offer a significant advantage.
