Defect and Position Measurement of Pipeline Inner Surface Defects
Su Bai, Hai Yang Jiang, Zhong Yao Zhu · Key engineering materials · 2013
The paper aims to measure the exact position while detecting inner surface defects of large scale pipeline. A realizable method using opto-electrical is presented in this paper, which can give the position of opto-electrical sensor. On-line measured data is automatically recorded and processed with precision because of the application of step motor and gear drive, as well as software controlling computer.
