凝汽器铜管残碳膜腐蚀实例分析

Example analysis of residual carbon film induced corrosion on condenser copper tube

对蒲山电厂凝汽器铜管的腐蚀泄漏原因进行了试验和腐蚀过程分析,找出了原始铜管存在的残碳膜和晶体缺陷是腐蚀的诱发因素,采取了针对性的镀膜处理和一系列运行管理措施。达到了预期的效果。

The cause of corrosion leakage of condenser copper tubes in Pushan Power Plant was tested and the corrosion process was analyzed,it was found that the residual carbon film existing on the original copper tubes and the crystal defects were the induced factors of corrosion.The cleaning--film coating treatment and a series of operation management measures were taken, with the expected effects achieved.
