Zeron Fastners
Nickel Alloys Monel 400 Socket Weld Flanges
Nickel Alloys Monel 400 Socket Weld Flanges (SW Flanges) are designed primarily for small nominal bore piping systems where high internal pressure and leakage integrity are critical. Zeron Fasteners manufactures and supplies these specialized high-strength flanges from the durable Monel 400 alloy (UNS N04400). The distinguishing feature of this product is the recessed shoulder into which the pipe is inserted and then secured with a single fillet weld around the outer diameter. This construction eliminates the need for beveling the pipe end, offering both strength and installation ease. Monel 400 is specifically utilized for its exceptional resistance to corrosion by high-velocity seawater, hydrofluoric acid, and caustic solutions. The primary application of these Monel 400 Socket Weld Flanges is in instrumentation lines, process lines handling hazardous fluids, steam lines, and small diameter pressure piping systems within chemical processing and offshore facilities.
