| Abstract: | The titanium tube heater, which is designed by our company for a device, is founded that the end of titanium tubes are corroded seriously and cause leakage in the production process and maintenance. According to the analysis of corrosion product and energy spectrum analysis on the surface and cross-section of the heat exchange tube, it is founded that the failure form is crevice corrosion and the failure factors are related with the medium and structure etc. |
