Home > Alloy 20 Pipe
Ojas Pipes and Tubes is a well-respected manufacturer and supplier of Alloy 20 pipes, proudly based in Kolkata, India. We specialize in providing corrosion-resistant piping solutions tailored for industries that deal with harsh chemical environments. Our reputation for delivering high-performance products is well-earned, as our Alloy 20 pipes are designed to withstand sulfuric acid, chloride stress corrosion, and pitting. Thanks to our advanced production capabilities and rigorous quality control, we ensure that our piping is not only reliable but also durable enough for demanding applications. We cater to various sectors, including chemical processing, pharmaceuticals, food, and marine, offering precision-engineered Alloy 20 pipes that not only meet international standards but also exceed our customers’ expectations.
The composition of Alloy 20 pipes primarily includes nickel (32–38%), iron, chromium (19–21%), molybdenum (2–3%), copper (3–4%), and trace amounts of niobium for stabilization. This unique blend provides outstanding resistance to sulfuric acid and corrosion caused by chlorides. In terms of mechanical properties, these pipes boast a tensile strength of around 620 MPa, a yield strength of 300 MPa, and an elongation of about 30%. The alloy strikes a perfect balance between strength and corrosion resistance, offering good weldability and formability, making it an excellent choice for severe chemical environments while ensuring mechanical stability under pressure and temperature.
