Purchase Monel 400 and K500 flanges from the leading manufacturer , STAINLESS INDIA. We offer ASTM B564 slip-on, weld neck, blind, threaded, and RTJ flanges. Global shipping is available along with test certificates.
STAINLESS INDIA is a reputable manufacturer, stockist, and exporter of Monel Flanges, providing high-quality Monel 400 and Monel K500 flanges suitable for high-corrosion, high-temperature and offshore applications. We also manufacture Monel Pipes, Monel Sheets & Plates, Monel Round Bars, Monel Butt Weld Fittings and Monel Forged Fittings for complete piping systems. Our flanges are engineered to provide exceptional mechanical strength and outstanding resistance to seawater, acids, alkaline solutions and hydrofluoric environments.
All flanges are produced in compliance with ASTM B564, ASME B16.5, B16.47, and B16.48 standards, guaranteeing international quality and precise dimensional accuracy.
Our Monel 400 & Monel K500 Flanges are precision engineered to provide outstanding corrosion resistance, long-lasting durability and exceptional strength in demanding industrial environments. For complete piping solutions, STAINLESS INDIA also supplies Monel Pipes, Monel Butt Weld Fittings, Monel Forged Fittings and Nickel Alloy Flanges manufactured according to international standards.
Monel flanges are high-performance nickel-copper alloy pipe flanges designed for severe corrosion environments. Manufactured from Monel 400 and Monel K500 grades, they offer exceptional resistance to seawater, hydrofluoric acid, alkalis and high-temperature service. STAINLESS INDIA manufactures slip-on, weld neck, blind, socket weld, threaded, lap joint and ring type joint (RTJ) flanges according to ASTM B564, ASME B16.5 and ASME B16.47 standards for offshore, marine, petrochemical, power generation and chemical processing industries worldwide.
Although stainless steel performs well in many industrial environments, Monel provides significantly better resistance to seawater, hydrofluoric acid, alkaline chemicals and chloride attack. This makes Monel flanges the preferred choice for offshore platforms, marine engineering, desalination plants and aggressive chemical processing facilities where maximum corrosion resistance and long service life are required.
