2205 Duplex Pipe is a metal alloy pipe produced from steel with various alloying components. The term refers to the material dual nature. Both austenitic and ferrite structures are present in the duplex material metallurgy. These characteristics combine the best qualities of ferritic and austenitic steel varieties in the material. The 2205 Duplex pipes could be cold-drawn or hot-rolled. The cold-drawn ones are seamless and precise in size, while the hot-rolled ones are stronger.
