Aman Pipes and Tubes, a prominent manufacturer and supplier based in Hyderabad, India, specializes in high-quality Duplex Steel Seamless Tubing designed for exceptional strength, corrosion resistance, and performance in tough environments. These tubes are crafted without welds, ensuring outstanding structural integrity, smooth internal surfaces, and reliable mechanical properties. Thanks to Duplex Steel’s unique dual-phase microstructure (austenite and ferrite), they boast impressive resistance to pitting, crevice corrosion, and stress corrosion cracking. Perfect for critical applications in industries like oil & gas, petrochemicals, marine, and power generation, Aman’s seamless tubing meets global standards such as ASTM A789/A790, guaranteeing durability and a long service life even in demanding conditions.
Duplex Steel Seamless Tubing generally consists of 22–25% Chromium, 5–8% Nickel, 3–5% Molybdenum, and controlled Nitrogen, all balanced with Iron. This specific alloy composition provides excellent corrosion resistance, especially in environments with chlorides and acids. The mechanical properties include a yield strength of approximately 450–620 MPa, tensile strength of around 620–800 MPa, and an elongation of about 25–30%. The seamless manufacturing process removes weak points, boosting pressure tolerance and fatigue resistance. With its sturdy construction and corrosion-resistant features, this tubing is ideal for high-temperature, high-stress, and chemically aggressive applications both offshore and onshore.
