Aman Pipes and Tubes, a well-respected manufacturer and supplier located in Hyderabad, India, specializes in top-notch Duplex Steel ERW Pipes designed for strength, reliability, and corrosion resistance in demanding applications. Crafted through the Electric Resistance Welding (ERW) process, these pipes boast uniform wall thickness, clean welds, and dependable mechanical performance. The unique blend of austenite and ferrite in duplex stainless steel offers remarkable resistance to chloride-induced stress corrosion and pitting. Aman guarantees that every pipe adheres to global quality standards, making them perfect for use in chemical, marine, oil & gas, and structural applications.
Duplex Steel ERW Pipes generally contain 22–25% Chromium, 5–8% Nickel, 3–5% Molybdenum, and Nitrogen, with Iron making up the rest. This mix provides exceptional corrosion resistance, particularly in environments rich in chlorides. Their mechanical properties include high yield strength (~450–620 MPa), tensile strength (~620–800 MPa), and an elongation of ~25–30%. The ERW process ensures pipes have precise dimensions, smooth surfaces, and robust weld integrity. Duplex ERW pipes retain their strength even under high temperatures and pressures, offering a cost-effective yet durable solution for various industrial systems and fluid-handling operations.
