Ashraf Nickel Alloys stands out as a top manufacturer and supplier of Super Duplex Steel Pipes in Riyadh, Saudi Arabia. We provide high-quality piping solutions tailored for industries that require outstanding strength and resistance to corrosion. Our pipes, available in grades S32750 and S32760, are designed to withstand pitting, crevice corrosion, and stress corrosion cracking, especially in harsh, chloride-rich environments. Adhering to ASTM, ASME, and international standards, our Super Duplex Pipes come in seamless, welded, ERW, and fabricated forms to meet diverse industrial needs. With remarkable durability, toughness, and longevity, these pipes are perfect for offshore, petrochemical, marine, and chemical processing applications.
Super Duplex Steel Pipes are crafted from approximately 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, which grants them exceptional corrosion resistance and a PREN greater than 40 for enhanced pitting protection. They boast a tensile strength ranging from 800 to 1,000 MPa and a yield strength of around 550 MPa, along with impressive impact toughness even at -50°C. The unique microstructure features a balanced blend of ferrite and austenite phases, ensuring high fatigue strength, minimal thermal expansion, and excellent weldability. With outstanding resistance to chlorides, seawater, and harsh chemicals, these pipes are perfect for high-pressure, high-temperature applications, guaranteeing long-term stability and performance in critical conditions.
