MEANS FOR PROTECTING FROM CORROSION METALLIC TANKS CONTAINING LIQUIDS TO BE HEATED; WATER HEATERS IN PARTICULAR

WIPO Patent Application WO2002059394

A3

The present invention concerns devices apt to protect from corrosion metallic tanks (1) containing liquids to be heated, water heaters in particular. According to the invention, a non-consumable type electrode, for cathode protection in particular, consists of the armour (5.1), preferably in titanium or its alloys, of one or more armoured electric resistances (5). Part of the surface of the said armour (5.1) can be subjected to a treatment that prevents the supply of current. The advantages of the invention include the constructional simplification of the electrodes and the fact that no scale deposits are formed on the surfaces of the armours (5.1) used as electrodes.
