【摘要】 通过建立模拟试验装置,测试三种铜换热管(黄铜、B10、B30,其中黄铜管和B10管分带螺纹和光管两种)在CaCl2溶液(质量浓度20%)中的耐冲刷腐蚀性能。试验过程中定期测量管路的腐蚀电位变化。试验结束后,解剖管状构件,从宏观和微观方面观察试验后换热管表面状态,综合对比分析三种换热管的耐CaCl2溶液腐蚀性的优劣。更多还原

【Abstract】 By creating a simulation device,test the corrosion-resistant performance of three kinds of heat exchange tubes in CaCl 2 solution.Measured the corrosion potential during the experiment.Dissected the tubes after experiment,observed the surface of heat exchange tubes by the macro and micro means,and comprised the pros and cons of corrosion-resistant perfomance of three kinds of heat exchange tubes in CaCl 2 solution.更多还原
