A piping plan depends on inspection history or inspection data in order to extract propensity of damage mechanism. The inspection data are ①Periodic maintenance inspection record (SDI), ②On-stream inspection data (OSI), ③Unplanned stop or extraordinary inspection records and ④corrosion-loop database visualized by evaluating corrosion rate as a corrosion system. Each of injury site of corrosion thinning with an organic acid as a specific injury mechanism, operating temperature conditions as a condition for extracting parts, fluid corrosion factor, structure factor, and material is quantified qualitatively or semi-qualitatively. It states that priority order by data visualization of damage propensity (Bayesian theorem) is required.
