油气管道外检测技术的综合应用

Integrated Application of the Detection Technique outside the Oil and Gas Pipeline

随着国家对油气管道生产运营安全的重视,管道的风险评价及完整性管理工作得到快速发展,而管道外检测技术就是其中一项关键的环节。为此,本文介绍分析了国内外常用的外检测技术及仪器,对各检测技术及仪器进行了综合比较。为了克服单一检测技术及仪器的局限性,建议使用单位根据自己的检测条件和目的选择不同的外检测仪器的组合方案。

With the fact that the country takes gas pipeline produce and transport safety seriously, risk valuation and completeness management of pipeline have being developed rapidly. However the pipeline outside detecting technology is a key link among them. Therefore the paper introduces the pipeline outside detecting technology and instrument of home and abroad in common use. After comparing with every detecting technology and instrument advantages and shortcomings, grouping schemes of detecting technology outside the oil and gas pipeline have been selected by users according to their different conditions and purposes in order to overcome the limitations of the unitary detecting technology.
