Abstract: Buried pipelines are widely used in the transportation of liquid and gas media such as crude oil and natural gas. Because of transporting under the bad working environment, they are possible to happen the leakage and explosion. The nondestructive testing(NDT) technique used by cell testing, welding testing and in-service testing of buried pipelines are reviewed. The purpose used the NDT methods are indicated. Excepted the normal NDT methods, some advanced NDT methods for buried pipeline are also introduced, such as X-ray real-time imaging, automatic ultrasonic testing, pipeline pig testing and ultrasonic guided waves testing methods.
