摘要

The main reasons of the oil pipeline accidents is wall thinning due to corrosion and cracks. This topicdevelops a broad-band ultrasonic pig technology to detect pipeline corrosion and cracks.Thetechnique can automatically measure wall thickness、diameter and detect axial crack flaw entirely andit can solve the misjudgments and miss judgment during ultrasonic pipeline corrosion inspection also.
