2014年3月24日,中国石油天然气集团公司鉴定输气管道提高强度设计系数工业性应用研究成果。鉴定报告指出:这项成果总体达到国际先进水平,这标志着我国又一项管道建设技术实现历史性跨越,走在了世界管道建设技术的前列。近10多年来,我国天然气管道技术快速发展。尤其是西气东输二线工程的成功建设,使我国长输管线建设水平处于世界领先地位,在高钢级大口径长输管道的建设领域由追赶者变为领跑者。为进一步体现高效节能的设计理念,为我国后续大规模管道工程建设奠定基础,中国石油管道建设项目经理部会同中国石油
March 24, 2014, China National Petroleum Corporation identified gas pipelines to enhance the strength of the design coefficient of industrial application research results. The appraisal report pointed out: This achievement has generally reached the international advanced level, marking a historic leap forward in China’s pipeline construction technology and taking the lead in world’s pipeline construction technology. In the past 10 years, China’s natural gas pipeline technology has developed rapidly. In particular, the successful construction of the second West-East Gas Pipeline Project has led China’s long-distance pipeline construction to a leading position in the world, becoming a leader in the construction of large-diameter long-distance high-grade steel pipelines. In order to further reflect the design concept of high efficiency and energy saving and lay the foundation for the follow-up large-scale pipeline construction in China, the China Petroleum Pipeline Construction Project Manager will join hands with PetroChina
