Experimental Research and Application of ECT X-probe

  • 摘要: 探头是阵列涡流检测的关键部件,介绍了一种新型的内穿过式涡流阵列探头——X-probe。分析了X-probe探头的工作原理,并通过试验研究,归纳了X-probe探头检测的不同类型缺陷信号特征、支撑下缺陷响应以及伤深与相位的关系。并介绍了X-probe探头在核电厂凝汽器传热管涡流检查的应用情况。试验结果表明,X-probe探头能够获取缺陷轮廓并依据AF和CF通道的幅值分辨出缺陷方向。现场应用证实X-probe探头具有良好的管板区缺陷检出能力,能很好地检测分辨并测量周向复合缺陷的伤深。
    Abstract: Probe is critical component of Eddy Current Array technique, so a new kind of eddy current internal array ECT probe named X-probe is introduced in this thesis。 The X-probe’s operation principle is analyzed. Its defects signal characteristic, signal response in TSP and relationship of defect depth & signal phase are studied through the experiments. Finally, application of X-probe in eddy current testing of NNP condenser heat-exchange tube is introduced. Experiment results show that X-probe can achieve defect profile and distinguish defect direction by AF and CF channel signal voltage. Field application proves that X-probe has good detection ability within TTS zone tube and can well distinguish complex defects and measure defects depth.
