随着石油天然气资源的开发和发展,对油气长输管道的综合性能要求越来越高,管线钢管也向着高强度、大直径和大壁厚的方向发展.介绍了当前管道建设的发展动向,以及对管线钢管提出的更高的要求.分析讨论了当前管线钢管研究中出现的热点问题,指出了我国在这些方面与国际先进水平的差距.%Along with exploitation and development of petroleum and gas, the performance requirements for long-distance transmission oil and gas pipeline is higher and higher, and the development of line pipe is towards high strength, large diameter and heavy wall thickness. In this article, it introduced development trend of current pipeline construction, put forward higher requirement for line pipe, analyzed and discussed hotspots occurred in current line pipe research, pointed out the difference between China and international advanced level on these aspects.
