...Abstract Lining the floor bottoms and vapor space within an Aboveground Storage Tanks (AST) is a well-proven method to mitigate internal corrosion of the carbon steel substrate. An AST is usually scheduled for out-of-service inspection at least 10 years after its initial in-service date; sometimes...

... corrosion of the aboveground storage tanks (AST) bottoms’ underside. Prevention of soil-side corrosion of the bottom plates of aboveground crude oil storage tanks is a major challenge in the oil and gas industry. Monitoring an AST bottom corrosion and VCI effectiveness is an important factor in determining...

...Abstract Soil-side corrosion of the bottom plates of aboveground storage tanks is the main cause of tank failure in 90% of the storage tanks in the Middle East. Chemical and topographical analysis of the soil revealed high salt content and sinkholes that lead to porous soil structure...

... ). SYSTEM DESCRIPTION Asphalt product is stored in insulated and heated aboveground storage tanks at temperatures that can exceed 350° F. The high temperatures of the steel tank bottom and surrounding tank cushion can cause rates of corrosion that are 4 to 8 times higher than steel at ambient temperatures...

...Abstract The effectiveness of cathodic protection on the exterior bottoms of aboveground storage tanks is best measured with permanent zinc or copper-copper sulfate reference electrodes placed under the tank bottom. The use of these electrodes is preferable to measurements taken at the periphery...

The designed systems have varied, however, the driving force in the present design is corrosion prevention. The evolution of these designs...

...INTRODUCTION Cathodic protection (CP) is commonly used to mitigate corrosion on the bottoms of aboveground storage tanks. To protect the environment from leaks due to through-floor corrosion, new tanks and refurbishment of old tanks are often designed with double bottoms. Figure 1 and Figure 2...
