Inconel 718 Weld Neck Flanges

The Inconel 718 Weld Neck Flange is a specialized, high-performance piping component recognizable by its long tapered hub that is butt-welded to the pipe. This design provides reinforcement and allows for superior stress distribution, making it the top choice for high-pressure, sub-zero, and elevated temperature applications. Zeron Fasteners is a reliable manufacturer and supplier in India, forging these flanges from Inconel 718, a nickel-chromium superalloy renowned for its exceptional strength and corrosion resistance up to 700°C. Its primary application is in critical piping systems within the oil & gas, chemical processing, and power generation industries where joint integrity is paramount.
