| Abstract: | Corrosion is one of the important problems plagued buried metal pipes, it is an important cause of pipeline accidents. The paper firstly reviews the mechanism of electrochemical corrosion, microbial corrosion and stray current corrosion of buried metal pipelines. Next, it introduces several anticorrosion measures such as corrosion inhibitor, special anti-corrosion coating, metal surface modification and cathodic protection, used in domestic and international. Finally, it bclieves that the method of modification the surface of metal pipelines will be widely used in the future. |
