The paper mainly discusses the corrosion mechanism of the oil tank and analyzes its corrosion process. Some new technologies, new technologies and new materials are selected rationally in each stage of anti-corrosion design and construction of a certain oil tank of a coastal power plant. Secondly, The technical characteristics of high-pressure water blasting and the advantages of this technology applied to the tank environment are analyzed. The characteristics of the formulation components of the anticorrosive coating are analyzed. For example, the epoxy and its curing agent are re-polymerized, Not only retains the polymerization function of epoxy, but also increased the chelating function, the steel surface can remain rust and other impurities with the steel substrate chelated into a stable structure of macromolecules; tidal function is also the technical characteristics of this coating, And this paint alkali resistance and epoxy equivalent, increased acid resistance, resistance to neutral salt spray test up to 10 0 0 hours, more than the average epoxy resin.This article describes a high-efficiency cathodes for tank protection sacrifices Anode, this anode current efficiency, potential stability, has been widely used in various types of domestic large tank
