摘要

The present invention relates to a method for evaluating the corrosion of the bottom of an oil storage tank using sediment water and sludge, comprising: preparing a mother liquor by mixing sodium chloride (NaCl) and calcium sulfate (CaSO 4 ); Laminating the sand on the steel material specimen and then laminating the mother fluid on the sand; A corrosion acceleration step of accelerating corrosion by applying a constant current to the mother liquid; And a corrosion evaluation step of evaluating a corrosion state by measuring an impedance of the steel specimen subjected to the corrosion acceleration step by applying an alternating current voltage to the mother liquid. According to the present invention, the bottom of the oil storage tank under the influence of the sludge, etc. due to the influence of the corrosive environment is different from the top of the oil storage tank. By manufacturing and creating a corrosive environment, there is an advantage that can accurately predict the corrosion life of the bottom of the actual oil storage tank.
