| Abstract: | In order to meet the requirement by the specification, sample pipes with artificial defectswere used for estimating automatic detection device. The results showed that the said device had strongcapability for detecting lateral and longitudinal defects while shallow defects such as Ф6.35 mmbottom-flat hole could not be effectively detected. With different detecting methods, different detectionrates of inclined defect were obtained. The angle between inclined defect and pipe axial direction wasan important factor influencing defect detection rate. |
