| Abstract: | The principle of pipeline metal magnetic memory （MMM） effect is proposed. Compared with other non-destructive testing（NDT） methods, the basic characteristics of MMM testing are summarized. Based on the status of MMM detectors, a new MMM/MFL detector is designed. The study on MMM technique with detection mechanism, signal processing and defeet identification are analyzed and summarized. The mechanism limitations are discussed, and the new development of pipeline testing with MMM technique is proposed. |
