A » Cathodic protection systems prevent pipe corrosion by making the metal surface a cathode of an electrochemical cell. This is achieved either by connecting the pipe to a more easily corroded "sacrificial" metal or by using an external power source to supply electrons, thereby reducing oxidation reactions. The process effectively halts corrosion by redirecting potential corrosive reactions to the sacrificial metal or counteracting them with an external current.

A »Cathodic protection systems prevent pipe corrosion by applying an electric current to counteract the natural electrochemical reaction that causes rust. This current makes the pipe a cathode, reducing the likelihood of corrosion. It's a widely used method to protect underground pipes, particularly in water treatment and distribution systems.
