Corrosion protection with galvanic anodes

The galvanic anodes are used for the protection of smaller objects such as short pipelines, storage tanks (oil, gasoline, liquefied petroleum gas):

Magnesium (Mg)  • zinc (Zn)  • aluminium (AL)

Basic requirements for a CP with galvanic anodes are:

✔  A good conductive electrolyte, soil

✔  Good insulation of the protection object

Advantage

✔  Low installation costs

✔  Lower maintenance costs

✔  No interference on foreign equipment

Disadvantage

✔  Limited power supplied by the given voltage of the used anodes

✔  For low resistive-soil and water

✔  Protection objects must be well insulated
