Summary:The invention relates to a method for predicting the service life of steel for an oil storage tank, and relates to the field of atmospheric corrosion simulation, a sample is subjected to a natural exposure corrosion test, and after the natural exposure corrosion test is completed, the corrosion weightlessness Vcorr is calculated; putting the treated sample into an ultraviolet aging test box to carry out a cyclic and alternate simulation acceleration test, and calculating the corrosion weight loss V'corr every 1-2 days during the simulation acceleration test; the corrosion weight loss V'corr is used for carrying out simulation acceleration test corrosion kinetic analysis and is compared with a corrosion weight loss Vcorr result of a natural exposure corrosion test, so that the service life of the steel for the oil storage tank is predicted. The method for predicting the service life of the steel for the oil tank in the industrial marine atmospheric environment in the Bohai Sea region is short in time consumpti
