Alloy 20 Pipe Spools Manufacturer & Supplier in India
Alloy 20 Pipe Spools are ready-to-use piping systems, consisting of welded pipes, fittings, and flanges, which are intended to be used in corrosive service environments to simplify installation and also to be leak-free. The pipe spools are extensively utilized in chemical and process industries where resistance to sulphuric acid and aggressive chemicals is a big concern. Carpenter 20 or UNS N08020 is a nickel-iron-chromium alloy containing controlled amounts of molybdenum and copper. Its common chemical composition consists of 32-38 % nickel, 19-21 % chromium, and copper and molybdenum that offer it great resistance to pitting, crevice corrosion, and stress corrosion cracking.
Alloy 20 Pipe Spools have high physical and mechanical characteristics with a tensile strength of at least 551 Mpa, a yield strength of 241 Mpa and an elongation of up to 30%, which means that they are resistant to high-pressure and temperature conditions. These spools are produced according to ASTM B729, ASME SB729, and come in different sizes and thicknesses. Alloy 20 Pipe Spools are used in chemical processing plants, oil and gas facilities, pharmaceutical units, heat exchangers, and pollution control systems where long service life and operational reliability are required. Kalpataru Piping offers high-quality manufactured products with strict quality management, on-time delivery, and complete material traceability to satisfy the challenging industrial needs.
