The Cathelco cathodic protection and anti‐fouling system

The following article results from our approach to Cathodic and Electrolytic Engineering Co. Ltd. to ask them to explain to ANTI‐CORROSION readers how their Cathelco system differs from the conventional impressed current cathodic protection system. The system uses special sacrificial anodes fitted inside pipe inlets but, unlike other systems designed to prevent corrosion, only a very small current is employed. Slow dissolution of the anodes into electrolytic products creates an environment which is hostile to the primary forms of marine fouling, while corrosion is said to be drastically reduced.—Editor.
