Corrologic Corrosion Management System

Corrologic is an engineered system utilising Vapour phase Corrosion Inhibitors (VpCI’s) for the protection of tank bottoms against soil side corrosion.

Soil Side Corrosion in Aboveground Storage Tanks (AST)

Soil side corrosion of aboveground storage tanks is a chronic problem in the oil and gas industry in the world at large. Corrosion of the underside of the tank bottom plates leads to metal loss and ultimately perforations in the tank floor. The results of such failures are dramatic on multiple fronts: loss of product, costly repairs, and environmental impact and safety concerns in the case of flammable fluids. Traditionally cathodic protection (CP) has been used for corrosion management of tank bottoms. However, experience has shown that CP protection can be interrupted by gaps in localized areas where the steel surface loses contact with the soil/electrolyte.
