Impex Tube India, a Mumbai, India-based company, is a well-known manufacturer and exporter of Duplex steel products of superior quality, supplying to different industrial applications. We are experts in Duplex Steel ERW Pipes, produced using high-quality duplex stainless steel alloys like UNS S31803 and UNS S32205. Pipes are supplied in various shapes, round, square, and rectangular, to offer versatility for wide-ranging applications. Providing superior strength, corrosion resistance, and longevity, our Duplex Steel ERW Pipes have been engineered to deliver superior performance in demanding industrial applications.
Our Duplex Steel ERW Pipes consist of a mixture of 22% chromium, 5-6% nickel, 3% molybdenum, and traces of nitrogen and manganese, giving them improved corrosion resistance. The mechanical properties are a tensile strength of 620 MPa, yield strength of 450 MPa, and good toughness, such that they can be used in high-stress environments. Their physical properties are a density of 7.8 g/cm³, a melting point of approximately 1350°C, and low thermal expansion, providing good resistance to stress corrosion cracking and such materials are well-suited for use in industries like oil, gas, and chemical processing.
