Steve Flanges is a top-notch manufacturer and supplier located in Canberra, Australia, specializing in high-quality Duplex Steel Welded Pipes. These pipes are celebrated for their remarkable strength, resistance to corrosion, and long-lasting durability. Crafted with cutting-edge welding techniques, they blend the advantages of both austenitic and ferritic stainless steels, offering impressive protection against stress corrosion cracking, pitting, and crevice corrosion. Steve Flanges provides Duplex Steel Welded Pipes in a variety of grades, diameters, and wall thicknesses, all adhering to international quality standards. These pipes are perfect for use in chemical processing, desalination, marine, and oil and gas sectors, where strength and corrosion resistance are absolutely essential.
The composition of Duplex Steel Welded Pipes includes chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), nitrogen, and a balance of iron. This unique dual-phase microstructure gives them double the strength of standard stainless steels while still ensuring excellent ductility and toughness. They boast a tensile strength ranging from 700–950 MPa and a yield strength of about 450–550 MPa, along with outstanding resistance to chloride-induced corrosion and oxidation. The welding process guarantees a consistent structure, robust joints, and improved mechanical performance in challenging environments.
