| Abstract: | This article briefly introduced application situation of X80 pipeline steel, and test results,such as chemical eomposition,tensile test,Charpy impact test and DWTT of domestic X80 φ1219mm×18.4 mm SAWH used in the 2nd West to East Gas Pipeline Project were analyzed. The results showed that low C and high Nb is characteristic of chemical composition and microstructure of pipe body is Bainite ; the strength reached the requirements of XS0 grade steel, and the toughness at low temperature is excellent as well as with DWTT property, its results are acceptable in ac- cordance with the technical specification of the 2nd West to East Gas Pipeline Project. |
