摘要

摘要某保温管道泄漏检测系统由于传感器导线故障而频繁出现故障。故障是由于绝缘变湿时施加的感应电流造成的。感应电流产生凹坑，凹坑是应力集中的部位。

Corrosion failure of sensor wire in leak detection system of thermally insulated underground pipeline

Abstract The leak detection system of a thermally insulated pipeline has frequently malfunctioned due to sensor wire failures. The failures are attributed to the applied sensing current when the insulation becomes wet. Pits were generated by the sensing current and acted as stress concentration sites.
