Procedure of cathodic corrosion protection - galvanic anodes

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




✔  Low installation costs

✔  Lower maintenance costs

✔  No interference on foreign equipment




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

✔  For low resistive-soil and water

✔  Protection objects must be well insulated
