| Abstract: | The working principle of the pipeline intelligent pig and the structure of ultrasonic probe array used to detect defects in oil/gas pipeline are introduced.The effects of the array'S radial position in pipe on defect resolution are analyzed.The causes leading to radial positioning error are investigated.An algorithm for the radial self-positioning is presented.The experimental results show that the radial self-positioning algorithm can eliminate the array'S space position error effectively and improve the defect resolution. |
