|
摘要
介绍了漏磁内检测的原理和漏磁信号的特性,利用环焊缝和磁路方式相结合的方法判读特征信号的极性,再利用特征信号一致性的比较原则,并结合特征信号的特征和盗油孔的方式,有效识别出管道盗油孔的信号,避免管道盗油孔信号的误判和漏检,为今后成品油管道漏磁内检测数据的分析和信号识别提供技术支持。
This paper introduces the principle of magnetic flux leakage in-line inspection and the feature analysis of the magnetic flux leakage signals based on the magnetic flux leakage technology for in-line inspection.This paper uses the method of combining circumferential weld and magnetic circuit method to identify the polarity of characteristic signal,through comparing the consistency of polar curve and the comparison with the size of the characteristic signal and the way of oil-stealing hole,the technology can effectively identify the pipeline oil-stealing hole,the technology can avoid misjudgment and undetected pipeline oil-stealing hole,and provide technical support for pipeline magnetic flux leakage in-line inspection data analysis and signal recognition in the future.
