The offered Duplex Steel Welded Pipes are metal alloy pipes that are made out of steel with different alloying elements. The name comes from the dual nature of the material. The duplex material contains bot the austenitic and ferrite structures in the metallurgy of the material. The pipes contain a high amount of chromium and a low amount of nickel. The strength and resistance of duplex pipes make them suitable for corrosive environments. Welded steel pipe(also known as welded pipe) is made of steel plate or steel strip after crimping, generally fixed length of 6 meters. The Duplex Steel Welded Pipes are very efficient and useful.
