Located in Hyderabad, India, Aman Pipes and Tubes is a well-known producer and supplier of duplex steel tubing, providing high-performance solutions for demanding industrial settings. Duplex steel tubing, which is well-known for its remarkable strength and resistance to corrosion, is perfect for applications involving exposure to harsh chemicals, high temperatures, and high pressures. Aman provides tubing that satisfies international quality standards, guaranteeing exceptional weldability, durability, and cost effectiveness. With a commitment to precision engineering and customer satisfaction, Aman serves industries including oil & gas, marine, petrochemical, and power generation with tailored Duplex Steel Tubing for critical applications.
The dual-phase microstructure of austenite and ferrite used to make duplex steel tubing normally contains balanced iron, nitrogen, 2.5–3.5% molybdenum, 4.5–7% nickel, and 21–25% chromium. This combination provides exceptional protection against stress corrosion cracking, pitting, and crevice corrosion. It offers elongation of 25–35%, yield strength of approximately 450–550 MPa, and tensile strength of 620–880 MPa. In harsh industrial settings, the tubing is perfect for structural and fluid-handling applications because it maintains exceptional toughness and fatigue strength while providing high resistance to chloride environments and elevated temperatures.
