Victor Nickelalloys, located in Abuja, Nigeria, stands out as a top manufacturer and supplier of high-quality Duplex Steel Pipes. Known for their precision, durability, and exceptional corrosion resistance, this company caters to vital sectors like oil & gas, chemical processing, marine, and desalination. Their Duplex Steel Pipes are designed to endure tough environments, high pressures, and corrosive fluids while ensuring structural integrity and reliable operation. Crafted with cutting-edge technology and rigorous quality control, these pipes deliver long-lasting performance, strength, and safety, making them perfect for demanding industrial and marine piping systems.
Typically, Duplex Steel Pipes are made from Duplex Stainless Steel 2205 or S31803, which includes about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, all balanced with iron. The unique dual-phase microstructure of ferrite and austenite grants them remarkable mechanical strength—almost double that of regular austenitic stainless steels—along with excellent resistance to pitting, crevice, and stress corrosion cracking. They boast high tensile and yield strength, outstanding fatigue resistance, and stability under mechanical and thermal stress. This blend of corrosion resistance and strength makes them ideal for critical industrial and marine applications.
