φ273漏磁腐蚀检测器在输油管道上的应用

Intelligent Pig Used in Oil Pipeline

为了掌握管道的内外腐蚀情况,在新疆的输油管道上采用了带发讯器的机械清管器和引进的智能清管器(φ273漏磁腐蚀检测器),准确地找到了管道管材的缺陷和内外腐蚀管段的具体位置。为预防管道因腐蚀穿孔而造成的跑油事故,提高管道的本质安全找到了一种较理想的方法。此方法可减少大修时间和大修费用,可使过去盲目的大修变为有计划的维修,在长输管道上有广阔的应用前景。

The signalling pig and introduced intelligent pig(273 leakage magnetic flux pig)have been adopted in Xinjiang oil pipeline in order to detect pipeline defects. The detecting results show that the defects of pipe steel and the locations of internal and external corroded pipe sections have been found out accurately. Using the intelligent pig can cut down the pipeline accidents caused by corrosion and leakage,decrease upkeep period and cost,and is also helpful to the work-out of maintenance program.
