To scientifically evaluate the remaining service life of the a387 grade 11 class2 welding, 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 a387 grade 11 class2 welding, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the a387 grade 11 class2 welding are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
