为保障国内长输管道通过高寒冻土区的运行安全,梳理了中俄两国的管道试压标准。从试压管段划分、试压介质、强度试验压力、密封性试验压力和稳压时间、输油气站工艺管道试压、管道试压渗漏检查方法、零度以下试压技术、强制性试压(重新试压和周期性试压)、试压监测管段、试压安全措施和环境保护等方面研究了中俄标准的相关规定,分析了不同标准之间的差异。介绍了俄罗斯标准关于高寒地区强度试压的特殊要求,以及试压环境保护等方面的先进理念,针对我国管道试压标准完善和制修订提出了建议。
In order to ensure the operation of domestic long-distance pipelines in the permafrost region, the standards of pipeline pressure test in both China and Russia are reviewed. From the pressure test tube section, pressure test medium, strength test pressure, tightness test pressure and pressure time, pipeline pressure test of pipeline, pressure test pipeline leak test methods below zero pressure test, mandatory pressure test Re-pressure test and periodic pressure test), test pressure monitoring pipe section, test pressure safety measures and environmental protection and other aspects of the relevant provisions of the Sino-Russian standards, analysis of the differences between different standards. The special requirements of Russian standard on strength test in alpine region and the advanced concepts of pressure test and environmental protection are introduced. Suggestions are made for perfecting and revising the pressure test standards of our country.
