核电站蒸汽发生器传热管与管板胀管段的涡流检测

Eddy current testing of heat exchange tube and tubesheet expansion section of steam generator in nuclear power plant

摘要: 核电站蒸汽发生器传热管与管板胀接位置在制造完成后，必须对其进行检测。利用涡流检测方法对胀管段实施了无损检测，同时对发现的缺陷进行了分析和总结，可为同行在以后的实际检测工作中提供技术参考。

Abstract: The quality of the expansion joint of the heat transfer tube of the nuclear power plant steam generator and the tube sheet must be strictly tested while being manufactured. The eddy current testing method is used to implement nondestructive testing of the expanded pipe section. At the same time, the defects found in the testing process are analyzed and summarized, which can provide technical reference for the peers in the actual testing work in the future.
