Rashdan Pipes and Tubes supplies high-performance Duplex Steel Seamless Tubing engineered for demanding applications requiring exceptional strength and corrosion resistance. Duplex stainless steels feature a balanced microstructure of austenite and ferrite, giving them superior mechanical strength and significantly higher resistance to pitting, crevice corrosion, and stress corrosion cracking compared to standard stainless steel grades. The seamless construction ensures uniformity, leak-free performance, and enhanced pressure-handling capability. These tubes are widely used in industries such as oil and gas, petrochemical, chemical processing, power generation, and marine sectors where reliability, durability, and long-term performance are critical.
Duplex Steel Seamless Tubing typically contains 21–23% chromium, 4.5–6.5% nickel, and 2.5–3.5% molybdenum, along with nitrogen for strength and corrosion resistance. This balanced chemistry offers high tensile strength (620–750 MPa) and yield strength nearly double that of conventional stainless steels. The seamless design eliminates weld defects, ensuring excellent structural integrity under high pressure. Duplex steels also offer strong resistance to chloride-induced corrosion, erosion, and fatigue. These properties make them ideal for harsh service conditions where high mechanical strength and superior corrosion protection are essential.
