NDT Inspection and Safty Assessment Methods of Oil & Gas Station Pipeline Defects

Some new NDT methods for detecting oil & gas pipeline defects were researched. A station pipeline testing system was established based on technologies such as ultrasonic guided waves, ultrasonic phased array and time of flight diffraction(TOFD). Safety assessment of station pipeline was made to give advice for repair and rehabilitation. All methods were studied to build an integrated inspection and assessment system of oil and gas station pipelines.
