Welded Pipes are of two types ERW and EFW. A process for producing welded pipe is Electric Resistance Welding (ERW) also known as Contact Welding. Processing of Electric Fusion Welding, also called Continuous Welding begins as coiled steel with appropriate thickness, width and weight is made. Duplex 2205 Welded Pipes are available in a wide range of sizes and properties. Due to the weld seam, lower operating pressures are stated in accordance with ASME compared to seamless pipes. In general Duplex Steel welded pipe possess tighter dimensional tolerances than seamless pipes and are less costly if produced in same quantities. Duplex 2205 Welded Pipe sizes range from 1/8" to 48" inches and the thickness of the pipes are as follows: Sch 5, Sch 5s, Sch 10, Sch 10s, Sch 20, Sch 30, Sch 40s, Sch 40, Sch STD, Sch 60, Sch 80s, Sch 100, Sch 120, Sch XS, Sch XXS, Sch 160. The Duplex Steel pipe is manufactured and finished according to dimension standards such as ANSI B36.10 and ANSI B36.19.

Properties of Duplex 2205 Steel
Duplex 2205 Cold Forming
Duplex 2205 has shown good formability in a variety of fabrications. The high strength of Duplex 2205 can pose problems. Even when the equipment has sufficient power, allowance must be made for higher spring-back caused by the grade’s high strength.
Duplex 2205 Hot Forming
2205 Duplex can be worked at maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the shape of the work piece is not compact, the edges may be significantly cooler than the bulk, and there is risk of cracking in the cooler regions.
Duplex 2205 Machining
Duplex 2205 is somewhat more difficult to machine than the 300 series austenitic stainless steels. Higher cutting forces are required and more rapid tool wear is typical.
Duplex 2205 Welding
2205 Duplex possesses good weldability but Should not generally be welded without filler metal as this may result in excessive ferrite.
Duplex 2205 Heat Treatment
Annealing temperature range is 1868 to 2012°F (1020 to 1100°C). Cannot be hardened by heat treatment, but Duplex 2205 does work-harden. Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion.
