To scientifically evaluate the remaining service life of the API standard 650 ground supported flat-bottom tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API standard 650 ground supported flat-bottom tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API standard 650 ground supported flat-bottom tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
