摘要:
简要介绍了国内外X80管线钢的应用情况,重点对西气东输二线工程用国产X80、φ1219mm×18.4mm螺旋埋弧焊管的化学成分、拉伸试验、冲击试验、DWTT等试验结果进行了统计分析。结果表明:其化学成分特点是低C高Nb,管体组织以粒状贝氏体为主,强度达到了X80钢级要求,且低温冲击韧性和DWTT性能良好,符合西气东输二线管道工程标准要求。
Abstract:
This article briefly introduced application situation of X80 pipeline steel,and test results,such as chemical composition,tensile test,Charpy impact test and DWTT of domestic X80φ1219mm×18.4mmSAWH 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 X80 grade steel,and the toughness at low temperature is excellent as well as with DWTT property,its results are acceptable in accordance with the technical specification of the 2nd West to East Gas Pipeline Project.
