摘要

Supposing corrosion of oil storage tank base-plate built on sand bed and on asphalt bed, laboratory corrosion tests in sand and in atmosphere were carried out. Utilizing extreme value statistics technique, analysis of corrosion behavior in sand was carried out as reported in our previous report. In this work, reproducibility of corrosion was inspected by comparison of scale parameters in extreme value distribution between field data and laboratory data. And as for the case when scale parameter being almost equal, acceleration rate of corrosion in laboratory to that in field was calculated from the parallel displacement ratio to each other. As a result, the laboratory corrosion test method, which can reproduce corrosion of oil storage tank base-plate in field, was established. Using this developed corrosion test method, corrosion of oil storage tank base-plate in field can be estimated quantitatively. And it would also be efficient for absolute evaluation of countermeasures not only being in present but also being under development for the future.
