A technology to detect corrosion damage and estimate extent and location within an enclosed volume. This coating condition monitoring (CCM) system is a network of sensors that measure conditions and electrochemical parameters to evaluate the health of coating and substrate for steel plates and tanks.
Conclusions: (1) vapor corrosion inhibitors (VCIs) can control corrosion on steel materials in contact with AST tank bottom backfill. (2) Efficiency of VCIs is affected by salt contamination or impurities in the backfill. (3) Corrosion of small areas of steel are not indicative of corrosion AST tank bottoms. (4) A path forward.
