摘要
简要叙述了石油库与加油站管线与阀门法兰锈蚀的现状及其腐蚀的原理和化学反应。重点介绍了法兰防腐的方法:一是聚氨酯泡沫防吸氧腐蚀法,二是防电化腐蚀法,三是硫酸铜化学置换反应法,四是盘根填充玻璃胶封堵法,五是胶带黄油封堵法,六是粘弹体防腐法,七是设置法兰保护罩法;比较了这几种方法,认为聚氨酯泡沫防吸氧腐蚀法简单、效率高、价廉,但拆卸法兰费力,而粘弹体防腐法效果优异,维护方便,使用寿命30年。
The corrosion status of flanges in the oil depots and gas stations in wet environment in Guangxi Province,the common corrosion principle of flange and the electrochemical reaction principle are briefly described. The main methods for anti-corrosion of flange are introduced,such as oxygen corrosion preventing method by using polyurethane foam,electrochemical corrosion preventing method, replacement reaction method by using copper sulfate, sealing method by filling glass adhesive in the packing,block method by using tape and grease,setting protective cover of flange, viscoelastic body anti-corrosion method. And the viscoelastic body anti-corrosion is recommended.
