Duplex 2205 Tube

Duplex 2205 Tube is stainless steel tube. It belongs to a family of stainless steels called as the duplex steels. There are different groups of this material. The pipes of this family could be formed either by cold drawing of by hot rolling and welding. The Alloy 2205 Seamless Tube is cold drawn and it has less absolute roughness. The seamless ones are less strong than the Duplex SS 2205 Welded Tubing but are highly precise in dimension. The precision in dimension is useful in highly sensitive applications which require precision in measurements and calculations. The specialty of Duplex 2205 Seamless Tube is that it contains a dual nature. It is neither ferritic nor austenitic but contains the best of both parts. The Duplex 2205 Tube is a super duplex grade tube and it contains ferritic and austenitic steel phases in its structure. Therefore the strength and the corrosion resistance properties are improved. The Duplex 2205 Seamless Tube could be used in applications like the marine and underwater application which are exposed to chloride ion rich environments.

The ASTM A790 Duplex 2205 Welded Tube is stronger and also possesses the same corrosion resistance properties. It has less absolute roughness but has more strength than the seamless pipes. The 2205 Duplex Tube applications require different shapes, sizes and pressure classes of the pipes. The SA 789 Alloy 2205 4 inch Tube is used in medium range fluid transfers. There are other sizes that range from ½” up to 42” and more. Depending on the application requirements, the pipes are sometimes custom made. These are used in petrochemical, chemical, food processing, pulp and paper, oil and gas and organic acid production industries as well. The Duplex SS 2205 Schedule 40 Tube can withstand high pressure and is used in condensers and heat exchangers.
