Products We Offer

Super Duplex Pipe

Super Duplex is a microstructure of ferritic and austenitic steel. A Super Duplex Pipe is made with a chemical composition of 25% chromium, 7% nickel, 4% molybdenum, and a few other elements. These pipes are highly resistant to corrosion and oxidation in stress-induced environments. A Super Duplex Steel Pipe possesses superior mechanical properties. These pipes have a yield strength between 485Mpa to 550Mpa. They have a tensile strength in the range between 690Mpa to 800Mpa. The Super Duplex Steel Tube can be easily fabricated and machined. These tubes can be easily elongated by 20% and still possess excellent workability. The Super Duplex 2507 Tube exhibits a hardness of 270 max Brinell. These tubes can be readily used in high-pressure and elevated temperature systems. They can be availed in single random, double random, and cut lengths. Alloy 2507 Super Duplex Tubing is highly versatile and has a long service life. They are used in chemical processing, seawater heat exchangers, distillation applications, etc. We are amongst a few Super Duplex Pipe Suppliers who make use of the latest technology and provide all test certificates to our clients.

The 2507 Super Duplex Stainless Steel Pipe is very strong and has diverse properties. These pipes are produced following ASTM, ASME, and API standards. They can be availed in schedules between SCH 5 to SCH 160 and SCH XXS. Super Duplex Welded Tubes are produced by combing pieces of sheet metal, strips via the welding process. These tubes are cost-effective and highly reliable in their operation. The Duplex 2507 Welded Pipe possesses a density of 7.8 g/cm3 and has a melting range of 1350 degrees C.

The Duplex Steel 2507 Pipe is dimensionally accurate and is very reliable. These pipes can be produced either by the hot or cold-rolling process. They can be availed in plain, threaded or beveled tubing ends. We are the 2507 tubing suppliers who offer a reasonable price on all our products. To find out more about our products, contact us for more information.
