摘要: 针对常规涡流Bobbin检测技术的局限性,开展了热交换器换热管管板区内壁的补充涡流检测,确定了涡流三混频检测技术和阵列检测技术的检测灵敏度,并对3种技术的检测结果进行了综合对比。Abstract: In view of the limitations of conventional eddy current Bobbin testing technology, the supplementary eddy current testing of the inner wall of the tubesheet area of the heat exchanger tube is carried out, the detection sensitivity of triple frequency mixing testing technology and array testing technology is determined, and the detection results of the three technologies are comprehensively compared.
