Adinox Overseas is a leading international supplier and exporter of premium-grade Duplex Steel S32205 Pipes for outstanding performance in demanding industrial conditions. Produced under the ASTM A790 specification and also realized by the designation UNS S32205, the pipes represent the ultimate solution for applications involving superior mechanical strength and corrosion resistance. Duplex S32205, also called 2205 Duplex, is a nitride-enriched duplex stainless steel with a microstructure of nearly equal austenite and ferrite content.
The UNS S31803 Pipes contains nearly 22% of chromium, 5-6% nickel, and 3% of molybdenum, which improves their resistance against a broad spectrum of corrosive chemicals. The two-phase microstructure of their material brings them a higher level of strength than single-phase austenitic grades, making them suitable for reducing the thickness of the material as well as overall weight without loss of durability. Adinox Overseas produces and deals in Duplex S31803 seamless and welded pipes as per ASTM A790 standards, maintaining the world-class quality and long-lasting performance.
With Duplex Steel S32205 Pipes, versatility makes them the favorite of industries that need them to resist general corrosion, SCC, pitting, crevice corrosion, and oxidation. These Pipes are commonly used in heat exchangers, condensers, and evaporators, especially for seawater and chlorine ion environments. It outperforms many other materials, thereby giving unparalleled performance that has been ideal for long-term service in systems of those critical applications.
Our huge inventory comprises Duplex S31803 seamless pipes, which are used for applications in high-pressure situations and rigorous service conditions in which internal smoothness and uniformity are paramount. We also have welded Duplex S31803 pipes for structural as well as low-pressure applications with the advantages of cost-effectiveness and superior performance. All pipes are stocked in multiple schedules, lengths, wall thicknesses, and end finishes as per client specifications
