Cathodic protection of steel water tank
What are the best materials could be used for cathodic protection of a water tank made of St-37 ( 2000 liters, 4mm thickness) ? Could it be protected using a single place for the cathode with multi wire connections? Should the cathodic cavity whch contains cathodic materials isolated? And what are the design concepts to design this system.

A commonly used system is to install a sacrificial anode made of a large piece of metal more electro-positive than the steel of the tank (eg, magnesium). It is connected to the tank with a strap of corrosion resistant metal such as copper, and buried in the ground. This is a common way of preventing corrosion in petrol tanks and steel stanchions in powerlines.
