Ultrasonic guided wave testing is widely used for the inspection of buried pipelines at present.The characteristics and application of inspection were introduced.As an example,pipelines in gas station were tested on-site and the testing result reliability was verified by excavation.Data analysis method was developed to analyze the inspection data.Comparison results showed that the ultrasonic guided waves could make it reality to test on-site quickly,and had wide prospect.
