Tanvir Nickel Alloys is a leading manufacturer and supplier of Duplex Steel Pipe Fittings in Cairo, Egypt, offering high-quality components designed for superior strength, durability, and corrosion resistance. These fittings are precision-engineered to ensure secure, leak-proof connections in demanding industrial, marine, and offshore applications. Tanvir Nickel Alloys’ Duplex Steel Pipe Fittings are widely used in oil & gas, chemical, petrochemical, and desalination industries, where exposure to corrosive media, high pressure, and extreme temperatures requires materials with exceptional mechanical and corrosion-resistant properties.
Duplex Steel Pipe Fittings are typically made from Duplex Steel grades such as S31803 or S32205, containing approximately 22% chromium, 5–6% nickel, 3% molybdenum, with the remainder iron, and small additions of nitrogen to enhance strength and corrosion resistance. They provide a tensile strength of 620–850 MPa, excellent yield strength, and superior resistance to stress corrosion cracking, pitting, and crevice corrosion. These fittings also offer good ductility, toughness, and weldability, making them suitable for high-pressure and corrosive environments.
