| Abstract: | In this paper, the Daniudi gas field of buried pipeline corrosion direct assessment （ECDA, ICDA） was combined to evaluate practiee and pipe wall thickness of transient electromagnetic （TEM） detection technology was applied. Basic detection was carried out by spacing measuring points along the pipe. The pipe wall thickness of the abnormal point was detected intensively so as to determine the most serious corrosion position and quickly grasp the quality of the whole pipeline in gas field, thus making the detection without digging and damaging the pipeline. |
