Alloy 20 pipes manufactured in India for chemical processing pharmaceutical equipment and acid handling industrial applications
Sagar steel corporation is a trusted Alloy 20 Pipes Manufacturer in India, which provides corrosion resistant piping solutions to aggressive chemical and process environments. Alloy 20 is a nickel-iron-chromium based alloy with coppers and molybdenum added in it, specifically designed to give it a good resistance to sulfuric acid and other hostile chemicals.
The alloy 20 pipes are commonly applied in chemical processing plants, petrochemical, pharmaceutical industries, food processing machinery, pollution control systems, and heat exchangers. These pipes are very resistant to pitting, crevice corrosion as well as stress corrosion cracking and are still high in mechanical strength and weldability. Alloy 20 pipes are offered in seamless and welded types that are available in different diameters, wall thicknesses and schedules and different lengths to suit project specifications.
