2205 duplex tube 1.4462 pipe price
Alloy 2205 provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steel tube in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.
Manufacturer and supplier of ASME SA 789 UNS S32205 Tubing, custom wall thickness in Inches/ mm
Duplex 2205 pipe has much better corrosion resistance than alloy grade 316. ASTM A790 Duplex 2205 Pipe produced to this specification is intended for use in applications where corrosion resistance is a primary concern. Typically, industries that use chlorine-based compounds in their industries prefer to use 2205 pipe because this alloy does not degrade easily in the presence of chloride ions. There are several reasons for its resistance to chloride stress-related corrosion cracking. The strength of 2205 duplex tube can be used in the pulp and paper industry. Applications for 2205 Duplex Tube vary and are also seen in food processing equipment, chemical processing vessels, and the oil and gas industry.
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. 2205 duplex tube 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.
