文摘“Those who owns the Middle East oil,will have the world.”The world’s major energy consumers-the United States and Russia holding the“energy card”meet in the Middle East.There are consensus and also contradictions in their energy strategies and interests.Based on the comparison between the energy strategy and policy of the two countries,this article aims to provide their experience in the Middle East for China to think and learn.
文摘为了满足中俄东线天然气管道工程380×10~8 m^3/a超大输气量的要求,大口径、厚壁、高钢级钢管便成为了主要选择。为此,结合该管道工程用外径为1 422 mm的X80钢管材技术条件的研究制订过程,对国内外管线钢管技术标准进行了对比分析,同时对外径为1 422 mm X80钢管材技术条件中的化学成分和止裂韧性等关键技术指标及制订过程进行了分析探讨,并对外径为1 422 mm X80钢管的开发过程及产品性能进行了介绍。通过生产试制和产品检测,证明现有技术条件合理有效地解决了化学成分控制、断裂控制、产品焊接稳定性等技术问题,不仅满足了工程要求,而且也适应生产情况,可以保障中俄东线天然气管道的本质安全。该研究成果可为中俄东线建设外径为1 422 mm X80钢天然气管道提供技术支撑,同时对于其他天然气管道工程技术条件的制订也具有指导意义。
