基于风险分析的管道检测(RBI)与评价

Risk-based Inspection and Assessment of Pipeline

目前,国内许多老管道普遍存在着老化、腐蚀、事故频发等问题,严重影响着输油(气)生产的安全,急需开展管道的检测评价工作。为避免以往检测的盲目性、无序性、投入大、准确性低等弊端,提出了建立在风险分析基础之上的管道检测(RBI)与评价方法。比较分析了国内外管道无损检测技术的现状和最新进展,介绍了国内外管道检测标准的制订情况,提出了对检测结果进行评价的方法和目前的研究重点及发展趋势。

For the most of old pipelines at present in China ,the problems in ageing .corrosion and accident are in existence,which throws an obstacle to the safe operation of oil and/or gas pipelines. To solve these problems,the inspection and assessment of pipeline is urgently need.Therefore,a method of risk-based inspection and assessment of pipeline (RBI) has been presented so as to avoid the blindness,disorder,high investment and low accuracy in pipeline inspection. The comparison and analysis on the status quo and the latest development of foreign and domestic pipeline NDT technology have been done. In the paper, the consititu-tion of relevent standards or codes for pipeline inspection at home and abroad is introduced,the assessment method on inspection results of pipeline and current key point in research as well as development tendency of RBI technology for pipeline are put forward.
