Ashraf Nickel Alloys stands out as a reliable manufacturer and supplier of Duplex Tube Fittings in Riyadh, Saudi Arabia. They specialize in delivering top-notch fittings that are perfect for high-pressure and corrosive environments. Made from Duplex Stainless Steel (like grades 2205 and 31803), these tube fittings boast impressive tensile strength and exceptional corrosion resistance, making them ideal for industries such as chemical processing, marine, oil & gas, and desalination. Thanks to their balanced microstructure of austenite and ferrite, these fittings resist pitting, crevice corrosion, and stress corrosion cracking. Available in various types like compression, instrumentation, ferrule, and hydraulic fittings, they meet ASTM, ASME, and DIN standards, making them perfect for critical fluid handling systems.
Duplex Tube Fittings are made up of about 22% Chromium, 5–6% Nickel, 3% Molybdenum, and Nitrogen, which gives them superior strength and corrosion resistance compared to regular stainless steel. They offer a tensile strength ranging from 620 to 800 MPa and a yield strength of 450 to 550 MPa, along with excellent resistance to chloride-induced stress corrosion cracking. Their unique dual-phase structure enhances impact toughness, fatigue resistance, and wear resistance, making them a go-to choice for extreme conditions. These fittings maintain their shape and durability even under high pressure and temperature, ensuring dependable performance in demanding industries.
