Frank the Tank
Tanks made from non-corrodible materials such as fiberglass reinforced plastic (FPR) or other non-corrodible materials do not require operation and maintenance for corrosion protection. However, tanks and piping made from metal that routinely contain regulated substances and are in direct contact with the ground need corrosion protection and require operation and maintenance.
Current Cathodic Protection Systems
An impressed current system
uses a rectifier to provide direct current through anodes to the tank or piping
to achieve corrosion protection. The
steel is protected because the current going to the steel overcomes the
corrosion-causing current flowing away from it.
test your system after performing maintenance to ensure you have not
short-circuited the system.
