Super Duplex Pipe is a category of duplex pipes. Duplex is a material that has the features of ferritic steel and of the austenitic steel. So this material possesses high strength from the ferritic structure and high corrosion resistance from the austenitic structure. These are available in different grades and classes. There are three classes of duplex steel; the duplex, super duplex and the lean duplex. The Super Duplex Seamless Pipe is built with chromium, nickel, molybdenum and nitrogen in its composition. Since the addition, there is high corrosion resistance and strength, but the impact resistance is less. The seamless pipes are easy to install and handle, and they are very much accurate in their dimensions. Super Duplex Welded Pipes on the other hand is much stronger but has high absolute roughness and needs tools to be fitted with. It is very good for welding applications.

The Super Duplex Steel Pipe has a PREN range of 38-45. The PREN number indicates the pitting corrosion resistance. The Super Duplex Stainless Steel Pipe is therefore included in high pitting corrosion prone environments such as the deepwater offshore oil drilling. The Super Duplex SS ERW Pipes are electric resistance welded and retains the strength after welding while not compromising the corrosion resistance properties. There are different standards and schedules that govern the diameter, wall thickness and the pressure containment capacities of the pipes. The 25cr Super Duplex SS SCH 40 Pipes for example belongs to a medium pressure class. The different needs of the applications mandate specific pipes such as the ASTM A790 Super Duplex 4 inch Pipes which is used in sea water and petrochemical industries. The ASME SA 790 Super Duplex Schedule 40 Pipes are one of the commonly used SS Super Duplex Hollow Pipes in the industries.
