摘　　要：输油管道腐蚀减薄和裂纹是泄漏爆炸等事故发生的主要原因。采用宽频超声液浸自动检测技术、多通道超声单元和微处理器等研究开发了长输管道腐蚀和裂纹宽频超声内检测器BUS-pig技术。该技术可全扫描高精度测厚、测径和裂纹探伤,而且可解决超声管道腐蚀检测中的误判、漏判问题。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.
