| Abstract: | The main reasons of the oil pipeline accidents are the pipeline wall thinning due to corrosion and the cracks. In this work a broad-band ultrasonic BUS-PIG technology is developed to detect pipeline corrosion and cracks based on the broad-band ultrasonic liquid-immersed automatic detect technology, multi-channel ultrasonic unit and microprocessor. The technique can be used to automatically measure wall thickness, diameter and detect axial crack flaw entirely, and it can be also used to solve the problems of misjudgment and missing judgment during ultrasonic pipeline corrosion inspection. |
