Aman Pipes and Tubes, located in Hyderabad, India, stands out as a top manufacturer and supplier of Duplex Steel Welded Tubing, known for its outstanding quality and performance in critical industrial applications. This tubing features a unique dual-phase microstructure that blends austenitic and ferritic properties, delivering remarkable strength, excellent resistance to corrosion, and a long lifespan. Aman Pipes and Tubes produces tubing that meets international standards, ensuring precision, reliability, and consistency in every piece. Catering to a variety of industries, including oil & gas, marine, chemical, and construction, the company is committed to providing durable and cost-effective tubing solutions designed for challenging environmental conditions.
Duplex Steel Welded Tubing is typically made up of 22–23% Chromium, 4.5–6.5% Nickel, 2.5–3.5% Molybdenum, and trace amounts of Nitrogen, with Iron as the primary component. This well-balanced composition grants it high corrosion resistance, particularly against stress corrosion and pitting caused by chlorides. The tubing boasts a tensile strength ranging from 620 to 880 MPa, a yield strength of about 450 MPa, and an elongation of roughly 25%. Its welded construction ensures strength and uniformity at the joints while preserving excellent mechanical integrity. Additionally, the alloy offers good fatigue strength and weldability, making it perfect for applications where both structural performance and corrosion resistance are crucial.
