摘　　要：分析了国内外X80钢管的制造、应用情况。针对西气东输二线管道的具体情况,对几十个工艺方案进行了研究,从建设投资、费用现值、年耗气水平、国内钢板钢管生产供应、施工能力、运输能力等方面进行了方案比较。推荐的管径1219mm、压力12MPa、钢级X80方案比其他方案经济合理,具有世界领先水平。国内钢厂、制管厂经过大量技术攻关,生产出了高质量的产品并实现了国产化,保证了西气东输二线管道工程的建设。The manufacture and application of the X80 steel pipe at home and abroad were analyzed. Based on the actual conditions of the second west-to-east gas transmission line,dozens of programs were compared and studied in the aspects of construction investment,present values of expenses,annual level of gas consumption,production and supply of steel plates,and fabrication and transportation of steel pipes in China. The recommend program of DN1219/12MPa/X80 was more economical and superior than others. Domestic steel mills and pipe mills produced high-quality products after technically tackling key problems,and achieved the nativeness of the project. It provided a guarantee to the construction of the second west-to-east gas transmission project.
