What preventive measure can be taken to avoid tank corrosion?

Applying tank liners is a highly effective preventive measure against tank corrosion. Tank liners serve as a protective barrier between the contents of the tank and the inner surface of the tank itself. These liners are usually made from materials that resist corrosive chemicals, thereby preventing any direct contact between the tank's metal surface and the corrosive substances. By minimizing this contact, tank liners significantly extend the life of the underground storage tank and reduce the likelihood of leaks caused by corrosion.

Regular cleaning, while beneficial for maintenance, does not directly prevent corrosion. It can help remove sludge and residue, but it doesn’t address the inherent vulnerabilities of the tank material exposed to corrosive agents. Galvanized steel is somewhat resistant to corrosion due to its zinc coating, but it’s not a foolproof solution, especially for USTs that may encounter harsh substances. Limiting tank capacity does not directly reduce the risk of corrosion; it could actually create circumstances like excess vapor space, which may lead to condensation and further corrosion risk. Therefore, the application of tank liners stands out as the most effective preventive measure for combating corrosion in UST systems.
