摘要
近年来,埋地管线在液体及气体输送领域得到了广泛地应用,与此同时,埋地管线的风险评估及完整性检测工作也得到了快速发展。为此,本文首先对基于GB/T 27512在役埋地管线风险评分法进行了重点介绍,提出了降低风险的策略;其次介绍分析了埋地管线内检测常用的方法及其优缺点;最后介绍了常用的外检测技术及仪器。
Recently, Buried pipeline are widely used to transport liquid and gas media, at the same time, buried pipeline risk valuation and integrity test also have got rapid development. Therefore this paper introduces a in-service buried pipeline risk valuation method based on GB/T 27512, and puts forward some strategies to reduce risk; Secondly some widely used internal detection techniques are introduced, their advantages and disadvantages are analyzed; Finally some commonly used outside detection techniques and related instruments are introduced.
