Studied on Nondestructive Survey Techniques for Coating Fault of Buried Steel Oil/ Gas Pipeline

摘要：

In this paper Pipeline Current Grads Method was used to survey and assess the buried fuel pipeline coating quality by nondestructive testing method. By analyzing the ground-pipeline current the fault location and damage degree of buried steel pipeline coating can be calculated and estimated, the pipeline level can be assessment by testing conductance and soil condition. Finally the influence of pipeline condition and external environment on survey current is analyzed, and the solutions are put forward.
