Duplex Seamless Pipe

The name 'duplex' for this family of stainless steels derives from the microstructure of the Duplex and Super Duplex Stainless Steel Pipes which comprises approximately 50/50 mixture of austenite and delta-ferrite. Duplex Steel Seamless Pipe have a higher chromium content, 20 - 28%; higher molybdenum, up to 5%; lower nickel, up to 9% and 0.05 - 0.5% nitrogen. Super Duplex Steel Welded Pipe is a duplex stainless steel, with a chemical composition of nearly equal proportions of austenite and ferrite. This combination allows the alloy to be stronger and tougher than standard austenitic steels. Duplex Steel EFW Pipe, Super Duplex Steel ERW Pipes and Duplex Steel Round Pipes are mainly used extensively in the offshore oil and gas industry for pipework systems, manifolds, risers, etc and in the petrochemical industry. As these Super Duplex Steel Square Pipes are highly corrosion and oxidation resistant so because of that Duplex Steel Rectangular Pipes are not suitable at elevated temperatures.
