| 针对传统超声导波检测技术仅能以A扫信号对管道缺陷进行轴向定位的局限性，笔者开展导波B扫成像技术的研究及应用。为满足大管径管道腐蚀缺陷的多维精确定位需求，通过研究导波局部加载及周向扫查技术，实现了轴向和周向缺陷的二维定位。通过实验室样管测试，验证了T(0,1)模态局部加载导波扫查技术在管道盲孔缺陷和横槽缺陷检测方面的适用性，且最高灵敏度低于2%截面损失面积。现场应用结果表明导波B扫成像检测可满足大管径管道腐蚀缺陷检测的需求。 |

| In view of the limitation that the traditional ultrasonic guided wave detection technology can only use A scan signal to locate the pipeline defects axially, the research and application of guided wave B scan imaging technology were carried out. In order to meet the needs of multi dimensional accurate location of corrosion defects in large diameter pipes, the guided wave local loading and circumferential scanning technology were studied to realize two dimensional location of defects in axial and circumferential directions. The applicability of guided wave scanning technology with T(0,1) mode local loading in the detection of pipe blind hole defects and transverse groove defects was verified through the test of sample pipes in the laboratory. The maximum sensitivity was less than 2% of the cross sectional loss area. The field application results show that the guided wave B scan imaging detection can meet the needs of large diameter pipeline corrosion defect detection. |
