We deal in Duplex Steel Welded Pipes that come in several grades like UNS S31803 and S32205, offering superior strength and corrosion resistance. These pipes come in various shapes like round, square, and rectangular, and are made of high-grade duplex stainless steel. Our offerings are designed to fulfill the requirements of various industrial uses with an emphasis on performance, durability, and quality.
Duplex Steel Welded Pipes consist of 22-25% chromium, 4-6% nickel, and 2-3% molybdenum with iron as the base metal and traces of nitrogen and manganese. These pipes provide outstanding mechanical characteristics, such as high tensile strength (620 MPa) yield strength (450 MPa) and great resistance against stress corrosion cracking and pitting. Having a density of 7.8 g/cm³, Duplex Steel Welded Pipes possess superior corrosion resistance in sour environments while retaining great weldability, formability and durability under high-temperature conditions.
