Corrosion is the loss of its metallic properties by entering into a chemical or electrochemical reaction with the environment it is in. In practice; used for cathodic protection of metal structuresin salt water such as offshore platforms, ship hulls, in-tank, underwater pipesand piers.
Pipe internal corrosive waters and waste transportation in the pipe for the transportation of waste and corrosive waters
– Heat Exchanger and Condenser Anodes
– Balancing tanks of ships and oil carriers
– Filled type to discharge leakage current
– Protection of Scaffolding Steel feet
– In the protection of the outer surfaces of the ships
– In special structures
A potential difference of approximately 250mV occurs between the iron metal protected by pure zinc anodes. This difference is sufficient for cathodic protection.
However, if there is even a little iron in the zinc anodes, this potential difference will decrease in a short time. Like iron, the small amount of lead and copper in the zinc anode has a harmful effect.
On the other hand, the presence of aluminum and cadmium metals in the zinc anode helps the anode to produce current properly.
