摘要
采用多频管中电流法(PCM+),对并行敷设的埋地输油管道外防腐层破损点缺陷进行检测,通过分析并行敷设输油管道自身特点以及多频管中电流法检测并行敷设输油管道的影响因素,得出了对并行敷设的埋地输油管道的检测方法,防腐层破损点缺陷开挖验证的结果证明了该检测方法具有可行性。
Multifrequency tube current method (PCM+)was used to detect the anticorrosion coating defects of buried oil pipeline in parallel, by analyzing the characteristics of parallel pipeline laying and detecting the influencing factors of parallel pipeline laying by PCM+, the detection method for parallel buried oil pipeline was obtained. The excavation verification result of anticorrosion coating shows that the detection method is feasible.
