Okoye Nickel Alloys is a reputable manufacturer and supplier located in Kinshasa, Congo, specializing in high-quality Super Duplex Steel Pipe Fittings. Known for our precision engineering and durability, we design our products to meet the tough demands of industries that operate in challenging environments. Our extensive range of fittings includes elbows, tees, reducers, and couplings, all crafted to ensure exceptional corrosion resistance and mechanical strength. With a strong commitment to quality assurance and timely delivery, Okoye Nickel Alloys caters to various sectors such as oil & gas, petrochemicals, marine, and power generation, both locally and internationally.
Super Duplex Steel Pipe Fittings are made up of chromium (24–26%), nickel (6–8%), molybdenum (3–5%), nitrogen, and other trace elements that boost their corrosion resistance and strength. These fittings boast remarkable mechanical properties, including high tensile strength (up to 800 MPa), excellent impact toughness, and outstanding resistance to pitting and stress corrosion cracking. Their unique duplex microstructure offers a well-balanced mix of austenitic and ferritic phases, making them perfect for use in highly corrosive and high-pressure settings.
