高强度管线钢的发展和挑战

随着石油、天然气消费量的增长,石油、天然气输送管线的重要性显得越来越突出.为了实现安全、经济的输送,管线钢钢管起到重要的作用.针对长距离高压输送管线的发展带来的对高强度钢管的巨大需求,论述了X70级钢管在全球的主要管线工程中的应用以及X80及其以上级别钢管技术的发展状况,指出:要实现X80及以上级别钢管的应用,还有很多工作要做,例如高强度管线钢的综合性能、断裂韧性、止裂性能的研究及焊接设计等,此外,还要完善和建立钢管性能标准、设计标准、施工标准等.

The Development and Challenger of High Strength Pipeline Steel

With the growth of oil and gas consumption,oil and gas pipeline becomes more and more important.Line pipe and line pipe steel plays the important role in safe and economy oil and gas transmitting.The development of long distance and high pressure pipeline brings the high demand for high strength pipes.The article states the X70 pipes application into international main pipeline,X80 pipes trial application and undated pipes technology of pipes above X80.Also it points out that X80 and above grade pipes application expects more works to finish such as researching apprehensive properties,impact toughness,prevent break properties of high strength pipeline steel and weld design.Furthermore the standards such as pipe properties,design and engineering should be established and improved.
