David Pipes and Tubes, located in Canberra, Australia, stands out as a top manufacturer and supplier of Duplex Steel Tube. They specialize in high-quality stainless steel tubes that are designed to offer outstanding corrosion resistance, mechanical strength, and long-lasting durability. Crafted with precision, these tubes boast smooth internal surfaces, consistent wall thickness, and exact dimensions. The Duplex Steel Tube from David Pipes and Tubes is perfect for industries like chemical processing, petrochemical, offshore oil and gas, desalination, and power generation, where resistance to chloride stress corrosion, structural integrity, and dependable performance in tough environments are crucial.
The composition of Duplex Steel Tube includes 22% chromium, 5–6% nickel, 3% molybdenum, and 0.14–0.20% nitrogen, which together create a balanced duplex microstructure. This unique blend provides excellent resistance to pitting, crevice corrosion, and stress-corrosion cracking, especially in aggressive, chloride-rich settings. The tube showcases a tensile strength ranging from 620 to 850 MPa, a yield strength of 450 to 550 MPa, and good ductility, ensuring it maintains its mechanical integrity even under high pressure and temperature.
