摘　　要：利用宽频超声检测技术开展了旋转探头和阵列探头管道超声内检测器(BUS-Pig)研究,实现了数据处理,管道腐蚀缺陷超声检测B、C扫描图像化和缺陷的三维图像化。实验结果表明:达到了管道腐蚀测厚精度±0.5 mm、腐蚀分辨率10 mm×10 mm的要求,并可检测评价管道截面尺寸。另外,对管道轴向裂纹的超声检测技术也进行了初步研究。Using the broad-band ultrasonic inspection technology to develop the research on ultrasonic Pig with rotary probes and transducer array,the data processing for B-/C- scan imaging and 3D imaging of pipeline corrosion flaw was realized. The inspection experiment achieved a requested corrosion sensitivity of ± 0.5 mm and a corrosion resolution of 10 mm × 10 mm. This developed technique can be used to measure the section dimensions of the pipeline. The ultrasonic inspection technology of the pipeline axial crack was discussed, too.
