Home > Alloy 20 Tube Fittings
Rudra Tubefittings, located in Kolkata, India, stands out as a trusted manufacturer and supplier of Alloy 20 Tube Fittings, specifically designed for tough industrial settings that face high levels of corrosion. Renowned for its remarkable resistance to strong acids—particularly sulfuric acid—Alloy 20 excels where regular stainless steels fall short. Rudra’s fittings are expertly machined to ensure leak-proof, vibration-resistant connections in critical fluid and gas systems. Their Alloy 20 Tube Fittings promise a long service life, impressive mechanical strength, and reliable sealing even in harsh conditions. Industries rely on these fittings for consistent performance, chemical stability, and durability in challenging processing environments.
Alloy 20 Tube Fittings are crafted from a nickel-iron-chromium alloy, enhanced with molybdenum and copper, which provides outstanding resistance to sulfuric acid, chlorides, pitting, and crevice corrosion. The mechanical properties include high tensile strength, excellent ductility, and dependable toughness across a range of temperatures. Precision-machined ferrules, bodies, and nuts guarantee tight seals, stability under vibration, and the ability to withstand high pressure. Alloy 20 maintains its structural integrity in aggressive chemical environments, making these fittings perfect for severe service applications that demand long-lasting corrosion resistance and strong mechanical performance.
