Duplex stainless steel pipes diameter 200 mm 2205 pipe

2205 duplex pipe is not recommended to be used at a temperature above 572¡ãF. Due to the presence of higher chromium, molybdenum, and nitrogen contents, 2205 duplex stainless steel tubes demonstrates superior corrosion resistant properties in comparison to the more conventionally used austenitic stainless steel grades 316 and 316L in most environments.

ASTM A789 UNS S32205 Duplex Tube & 22 Cr Duplex Stainless Steel Pipe supplier

The internal microstructure of the 2205 duplex stainless steel tube is two phases and one phase. This microstructure is an equal proportion mixture of ferrite and austenite in a duplex 2205 stainless steel tube. The 2205 duplex stainless steel tubes work well in those applications which contain a high concentration of chlorine. Chloride ions, which are normally detrimental to conventional stainless steels, do not cause any damage to the much stronger Duplex Stainless Steel Pipe. The chemistry of  2205 duplex stainless steel tube ensures better performance with higher mechanical properties in comparison to austenitic stainless steel pipes.

The higher percentage of chromium in the alloy of duplex stainless steel seamless pipe makes 2205 duplex stainless steel pipe resistant to oxidation. The resistance to oxidation is on account of the developed self-healing passivate oxide layer, which acts as a barrier against corrosion. The passivated layer may get depleted in the presence of less oxygen. However, if the content of atmospheric oxygen increases, the layer starts to heal or develop once again on the 2205 duplex stainless tubing material, which is why it is referred to as a self-repairing layer. Designers may have the option to reduce the wall thickness of the duplex 2205 welded pipe, because of its high yield strength.

The yield strength of this material is almost two times that of the usually used austenitic stainless steel grade. Unlike austenitic steel pipe, the Duplex 2205 Tube may at times exhibit magnetic behavior because the microstructure of its alloy contains about 50% ferrite. The mixed microstructure of the duplex steel pipe also gives its superior corrosion resistance properties in addition to increasing its mechanical ones.
