Cathodic protection conditions

The application conditions for cathodic protection are as follows: 1. The corrosive medium must be conductive in order to establish a continuous circuit. 2. The protected metal material must be able to undergo cathodic polarization easily in its surrounding medium; otherwise, high power consumption will occur, and cathodic protection is not suitable. 3. For complex metal equipment or structures, their geometric \"shielding effect\" must be taken into account to prevent uneven distribution of the protective current. 4. Electrical insulation has become an essential condition for cathodic protection. 5. Corresponding to electrical insulation, electrical continuity between the protected structure systems is another requirement for cathodic protection.
