摘　　要：为了控制和防止舰船中异种金属接触导致的电偶腐蚀,本文提出采用严密的电绝缘方式控制电偶腐蚀的思路及管系在干燥和浸水两种状态下电绝缘性能的测量方法,并考查了4组异种金属之间的电绝缘效果.结果表明,采用电绝缘法兰、套管、以及在整个管系中采用电绝缘吊架、支架,是舰船海水管系中防止异种金属接触腐蚀目前最有效的绝缘措施.In order to control and avoid galvanic corrosion of dissimilar metals for seawater pipelines in naval vessel＇s, an electric insulating method has been put forward in this paper. At the same time, the measuring methods of insulating performance in both dry and immersed conditions have been proposed and the insulating effect of four sets of dissimilar metals have been evaluated. The results showed that the insulating flanges, sleeves, brackets were the most effective way to prevent galvanic corrosion of dissimilar metals for seawater pipelines in naval vessel＇s.
