Max Tube Fittings is a reliable manufacturer and supplier based in Delhi, India, specializing in top-notch Super Duplex Steel Tube Fittings that are perfect for high-performance fluid and gas transfer systems. Made from high-quality Super Duplex stainless steel (UNS S32750/S32760), these fittings boast outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, even in harsh, chloride-rich environments. With precision engineering, they offer exceptional strength, durability, and leak-free connections, making them a go-to choice for demanding sectors like oil & gas, petrochemical, desalination, marine, and power generation, where reliability and longevity are essential for smooth operations.
Super Duplex Steel Tube Fittings feature a well-balanced microstructure of austenite and ferrite, providing them with double the strength of regular austenitic stainless steels. They are enriched with high levels of chromium, molybdenum, and nitrogen, which significantly boost their corrosion resistance and mechanical properties. These fittings deliver impressive tensile and yield strength, excellent fatigue resistance, and remarkable durability under high-pressure and high-temperature conditions. Their sturdy composition guarantees superior dimensional stability and a long service life, making them the preferred option for critical piping systems and process applications in highly corrosive or offshore settings.
