How to establish a correct method to evaluate the life of oil storage tank

In order to establish a correct method to evaluate the life of oil storage tank, it is necessary to work out the criterion of strength and crack of oil storage tank, the mechanism of mechanical damage, the mechanism of corrosion, the mathematical model of fatigue crack growth and so on, and compile a computer program.

In the process of programming, it is required to select the data of operation parameters, plates, reinforced accessories, metal properties, corrosion degree, mechanical damage defects, etc. of the oil storage tank under various conditions, and divide these data into two categories (i.e. necessary data and temporary data). Except for mechanical damage, static crack stability and dynamic crack stability, other data are necessary. During the operation of this program, the development trend of corrosion degree, the dynamic change of crack and the accumulation of damage can be input. At the same time, special working conditions can also be input.
