Eddy Current Testing and Failure Analysis of Titanium Tubes Used in Heat Exchanger
热交换器传热钛管的涡流检测及失效分析

In order to find out the leakage cause of titanium tubes used in a heat exchanger in a nuclear power station,eddy current testing was adopped to examine the samples of titanium tubes from this station.Based on the results of testing and the operation history of the station,failure types of the tubes were analyzed.It follows that the high speed of sea-water with high content of mud and sand and the peeling-off of corrosion resistant rubber from the inner side of the exchanger wall induced solid blockage and ...
