With an engineering excellence and quality-based foundation, Mumbai, India-based Impex Tube India is a well-established name in metal pipe production and supply. Its one of the major products is Duplex Steel Seamless Pipes, made of high-quality duplex stainless steel having double-phase microstructure with strength and corrosion resistance. These seamless pipes find applications in any desired shapes round, square, and rectangular shape with guaranteed leak-free operation and high durability, making them fit for demanding marine, petrochemical, and structural industry applications.
Duplex Steel Seamless Pipes consist of roughly 22% Chromium, 5–6.5% Nickel, 3% Molybdenum, and the remainder Iron, having the best corrosion, pitting, and stress corrosion cracking resistance properties. Mechanically, they provide great strength with a tensile strength of approximately 620 MPa and yield strength of 450 MPa, with good impact resistance. Physically, such pipes possess a density of 7.8 g/cm³, a melting range of 1350–1450°C, and reduced thermal expansion. All these make Duplex Steel Seamless Pipes best suited for corrosive, high-pressure, high-temperature, industrial conditions.
