摘　　要：分析了多级闪蒸海水淡化产品水水质特点,研究了淡化水对铸铁管网的腐蚀影响。利用稳定指数法、失重法、电化学分析和腐蚀产物的XRD检测等方法开展了实验研究。实验结果显示了淡化水对铸铁试片的腐蚀程度及淡化水对铸铁腐蚀产物的类型,可为淡化水进入市政管网提供参考。The characteristics of product water from multi-stage flash desalination（MSF） are investigated and its influence on municipal water pipe which is made of cast iron is researched.Corresponding experiments have been completed by different methods such as stability index,weight loss,electrochemical analysis and XRD testing.The results provided the corrosion degree of the cast iron specimens and the types of corrosion products caused by desalted water.Thus,this study would be meaningful for the usage of desalted water in municipal pipe networks.
