What is cathodic protection for tanks ?
what is cathodic protection for tanks : Cathodic protection for above-ground storage tanks (ASTs) is a method used to prevent corrosion of the tank’s metal surface by providing a protective current that counteracts the natural corrosion process. Cathodic protection is commonly used to protect steel ASTs that store liquids or gases such as petroleum products, water, and chemicals.
The two types of cathodic protection systems used for ASTs are sacrificial anode systems and impressed current systems. In a sacrificial anode system, one or more anodes made of a metal that is more reactive than the metal of the tank are attached to the tank. The anode material will corrode preferentially to the tank material, thereby protecting the tank from corrosion. The anodes must be periodically replaced as they corrode.
In an impressed current system, an external power supply is used to apply a protective current to the tank. The current is applied through anodes that are attached to the tank. The impressed current system can provide a more precise and consistent level of protection than a sacrificial anode system, but it is also more complex to install and maintain.
The selection of the appropriate cathodic protection system for an AST depends on several factors, such as the size and shape of the tank, the material of the tank, the type of liquid or gas being stored, and the environmental conditions. Proper design, installation, and maintenance of a cathodic protection system are essential to ensure its effectiveness and safety.
Routine monitoring of the system is also important to ensure that the anode or impressed current system is functioning properly and the tank is adequately protected from corrosion. Regular inspection and maintenance of the tank itself are also necessary to identify and address any signs of corrosion or other damage.
