输气管道内腐蚀直接评价方法

Internal Corrosion Direct Assessment Approach for Gas Transmission Pipeline

基于完整性管理的内腐蚀直接评价(ICDA)方法具有成本低且无须进入到管道内部等优点,叙述了管道ICDA的重要性,并针对干气输送管道ICDA的原理、评价过程和应用影响因素等方面以及ICDA应用的局限性进行了较为详细的探讨。指出国内应该加强ICDA技术的研究和应用。

At present,as the progressive attention is paid to the integrity management of pipeline in china,ICDA based on integrity management is concerned due to its unique advantage of low cost and no need accessing to the internal of pipeline.The paper addresses the importance of internal corrosion direct assessment and briefly presents the principle,evaluating process and its influencing factors of ICDA for dry gas transmission pipeline,and then the paper discusses the limitations on the application of ICDA.Finally,the author points out that the research and application of ICDA technology should be enhanced
