Abstract: The Teletest Focus⁺ system was used to carry out the ultrasonic guided wave testing on the buried pipeline in the station. The accuracy of the ultrasonic guided wave detection technique in the corrosion detection of buried pipeline in the station was analyzed. The results show that the results of the test and evaluation are in accordance with the results of excavation tests. The technique can be applied to the corrosion detection of buried pipelines in stations. Effective detection of the buried pipeline in station can be achieved through reasonable choice of sensor installation location.
