Section 11-5-2-280.1-3-3.2 - Galvanic Systems

Galvanic systems are also known as sacrificial anode systems because an anode (usually zinc or magnesium) corrodes instead of the protected metal. Because the anode corrodes instead of the metal that it is protecting, the anode is said to sacrifice itself. Sacrificial anodes are connected directly to the structure to be protected by either welding or mechanical connection of lead wires.

Galvanic systems are generally limited to those tank components that are well coated with a dielectric material (sti-P3 tanks or fusion bonded epoxy coated steel piping) because the available current output of these systems is low. Attempts to protect long runs of uncoated piping or uncoated tanks generally is not practical because the useful life of the anodes is too short or the number of anodes needed is too great.
