Jyoti Steels is a prominent manufacturer and supplier of Super Duplex Steel Tubing with headquarters in Mumbai, India. A premium quality and high-precision engineering company, Jyoti Steels offers tubing solutions with very high corrosion resistance and mechanical strength. The tubes are produced using state-of-the-art technology and according to international standards and specifications. These tubes can be perfectly used in harsh environments. Supplying industries like oil & gas, petrochemicals, marine, and power, Jyoti Steels makes sure that its Super Duplex tubing fulfills the high requirements of domestic as well as international customers.
Super Duplex Steel Tubing generally consists of Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (~0.2–0.3%), and Iron (balance), with trace elements like Copper (~0.5%), Tungsten (~0.5–1%), Manganese (<1.2%), and Carbon (<0.03%). This equiaxed structure provides enhanced resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. The tubing possesses high tensile strength (~800 MPa), yield strength (~550 MPa), and elongation of about 25%. Having a density of 7.8 g/cm³ and thermal conductivity of ~15 W/m·K, it operates efficiently in high-pressure, high-temperature, and corrosive operating conditions.
