galvanic anode


Also found in: Dictionary, Wikipedia.

sacrificial anode

A metal plate used in cathodic protection (i.e., the protection from corrosion) of piping or other equipment to which it is electrically connected. This metal plate must be more corrodible than the piping to which it is attached.

If galvanic anodes are used for cathodic protection in an area of AC influence and if test stations are available, the following tests should be conducted during each pipeline corrosion survey using suitable instrumentation: a) Measure and record both the AC and DC currents from the anodes, b) Measure and record the AC & DC pipe-to-soil potentials.
