| Abstract: | Long Range Ultrasonic guided wave Test System has some advantages in detecting and evaluating inservice pipelines. In this paper the system of simulated defects in test pipe is introduced, and the experiment with pipe 210 mm in diameter and 30000 mm in length detected using ultrasonic guided waves are carried out, the testing results are well consistent with actual sites and sizes of three kinds of defects ,which are simulated as crack, hole and local corrosion thinning. |
