Mirza Pipe and Tubes, a reputable manufacturer and supplier based in Riyadh, Saudi Arabia, is well-known for providing top-notch piping solutions that adhere to international standards. Among their extensive range of products, Duplex Steel Tubing stands out for its remarkable combination of strength, toughness, and resistance to corrosion. With a unique dual-phase microstructure of austenite and ferrite, these tubes excel in resisting stress corrosion cracking, pitting, and crevice corrosion. Mirza Pipe and Tubes caters to various industries, including oil & gas, petrochemical, marine, chemical processing, and power generation, ensuring dependable and long-lasting performance.
Duplex Steel Tubing is composed of approximately 22-25% chromium, 4-6% nickel, 3-5% molybdenum, with the balance being iron. This unique composition combines the qualities of both austenitic and ferritic stainless steels, resulting in excellent corrosion resistance and high strength. It has impressive mechanical properties, including a tensile strength of 620-850 MPa, yield strength of 450 MPa, and elongation of 25%. The key advantages of Duplex Steel Tubing include superior resistance to stress corrosion cracking, pitting, and crevice corrosion. Additionally, its high strength-to-weight ratio allows for reduced wall thickness, making it both cost-effective and durable, especially in demanding environments.
