In this paper, the acoustic emission instrument is used to collect the signal emitted by the steel pipe when it is damaged in electrochemical corrosion. Through the analysis and processing of the collected waveform signal data, the change law of the energy and effective voltage value of the steel pipe corrosion damage is obtained. It is found that the closer the sensor is to the serious corrosion area of the steel pipe, the more the number of impact, energy and effective voltage values is collected. The real-time dynamic detection of the steel pipe corrosion damage development process is realized. The results show that the acoustic emission technology can be used to detect the corrosion damage of steel pipe accurately.
