Corrosion Control Systems for Various Tank Foundation Designs

Corrosion control systems used for the underside steel plates of above-ground storage tanks (ASTs) may not provide adequate protection in certain situations. Specifically, severe corrosion of the chime area may lead to unplanned outages and could impact the tank’s structural integrity near the critical weld between shell plates and chime/floor plates. Some design and construction […]

How to Determine Whether VCIs, CP, or Both Should be Used to Protect ASTs from Corrosion

Soil Side Bottom (SSB) corrosion of aboveground storage tanks (ASTs) is a major cause of tank bottom failures and a constant problem for tank owners in the oil and gas industry. The use of Vapor Corrosion Inhibitors (VCIs) and Cathodic Protection (CP) are common practices for protecting ASTs from corrosion. Below I will briefly review […]
