Super Duplex tubes
Super Duplex 2507 Pipe is a super duplex material made metal pipe. The super duplex is an alloy of chromium, molybdenum and nickel. The material has very high corrosion resistance properties and is resistant to pitting corrosion, crevice corrosion and uniform corrosion as well. The Alloy 2507 Seamless Pipes are produced through a method called the cold drawing. Cold drawn pipes are seamless or have smooth surfaces. They are good to be used in aesthetic looking and precise applications. The dimensions of the seamless pipes are very precise. The 2507 Welded Pipes are produced through a procedure called the hot rolling and welding. These pipes are stronger than the seamless ones and can be welded easily. The 2507 Super Duplex Seamless Pipe is used with high pressure and temperature applications alike the Duplex 2507 Stainless Steel Welded Pipes but is less strong than the welded ones. Each of these has their own benefits of being used in different systems.
The applications of both these types include pulp and paper industry, fuel gas purification plants, heat exchangers, water desalination plants, sea water systems, chemical and food storage tanks. The electric resistant welded 2507 Duplex Stainless Steel ERW Pipes are used for welding ease. One of the most commonly used is the Super Duplex 2507 F55 Hollow Pipe. There are other types and shapes of pipes as well. There polished pipes such as the Saf Super Duplex SS 2507 Polished Pipe and other special types such as the Sandvik Saf 2507 Pipes. All these pipes have a dual nature from the material they are made from. The duplex steel has ferritic and austenitic phases in its microstructure. This enables the pipes to have the best strength properties from the ferritic steel phase and the best corrosion resistance from the austenitic phase. The 2507 Stainless Steel Pipes therefore is a good alternative for other pipes materials.

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.
