Underside Corrosion of above Ground Storage Tanks (ASTs)|
RIM-RUKEH, A. ; OKOKOYO, P. A.
Underside corrosion of a failed above ground storage tank (AST) was investigated by the physio-chemical analysis of water sample that was ingress between the tank bottom plate and the concrete foundation. The results of the water sample analysis showed pH (5.8), temperature (30°C), Conductivity (4800 μs/cm), dissolved oxygen (3.5 mg/l), chloride (674 mg/l), carbonate (16.90mg/l) and nitrate (23.10 mg/l). The levels of the parameters studied were generally high and above statutory safe limits. The results showed that the physico-chemical characteristics of the water sample have diagnostic and predictive values to implicate and promote underside corrosion of the studied above ground storage tank. @JASEM.
