2205 duplex stainless steel tubes are available in different sizes, wall thicknesses, and forms like seamless or welded. Other sizes are available from ½” to 42”. Tube dimensions can be customized according to application requirements. They are also used in the petrochemical, chemical, food processing, pulp and paper, oil and gas, and organic acid production industries. Duplex SS 2205 schedule 40 tubes can withstand high pressure and are used in condensers and heat exchangers.

Technically, the microstructure of 2205 duplex stainless steel tubing is about 50% ferrite and 50% austenite. Therefore, the properties inherited from these two classes make this nitrogen-enhanced duplex 2205 seamless tubing ideal for use in industries such as food processing, oilfield piping and heat exchangers, and flue gas desulfurization. Heat exchangers generally experience an increase in temperature because they work on the principle of heat transfer. While A789 UNS S31803 tubing can hold itself at high temperatures, it is not recommended for use at temperatures above 600° F, where duplex 2205 tubing will become brittle and rot.
