Cathodic protection (CP) testing is a critical process for gas stations, particularly for those with underground storage tanks (USTs) and associated piping systems. This method is used to prevent corrosion of metallic structures, such as tanks and pipelines, by using a sacrificial anode or impressed current system to redirect the electrochemical process that causes corrosion.

Cathodic protection testing is essential for preventing corrosion-related failures in underground storage tanks and fuel delivery systems at gas stations. Regular testing and maintenance of CP systems not only help to comply with regulatory standards but also enhance the safety and longevity of the fueling infrastructure. Always refer to manufacturer guidelines and local regulations for specific testing procedures and requirements.
