摘要
本文首先分析了钢管漏磁在线检测装置的组成,检测信号的采集方法。对采集到的钢管漏磁检测信号采用特征分析和非线性方法对缺陷大小进行定量识别。最后介绍了几个钢管漏磁在线检测在管道腐蚀检测、无缝钢管探伤和石油套管缺陷检测中的应用实例。
The paper analyzes the system of steel pipeinspection by magnetic flux leakage (MFL) method andthe collected method of the signals of steel pipe MFL. Thealgorithm of feature extracting and nonlinear are applied inthe analysis of the signals for MFL and the quantitativerecognition to steel pipe pits. The inspection examples thatare applied in oil-gas pipe inspection, seamless steel tubeinspection and oil steel tube inspection are showed.
