Cathodic protection system is a method used for the electrochemical preservation of metal. This method is commonly employed to safeguard metal pipes, tanks, ship hulls, and other metal structures against corrosion. Cathodic protection utilizes an electrochemical reaction to prevent or reduce the natural corrosion of metals.
This system generally consists of two fundamental components:
Anodes: Elements connected to the metal surface where corrosion occurs, serving as a kind of "sacrifice" allowing the protected metal to corrode. Anodes are typically made of more reactive metals such as zinc or aluminum.
Cathodes: Elements connected to the surface of the metal to be protected, supplying electrons to prevent corrosion. Cathodes are usually powered by a DC current from a power source.
The operation is as follows:
Electric Current: An electric current is supplied between the anode and cathode. This current involves an electron flow between the oxidation reaction at the anode and the reduction reaction at the cathode.
Oxidation and Reduction: On the anode, metal oxidizes (corrodes) on the protected metal surface, releasing electrons. These electrons are directed to the cathode by the DC current from the source. At the cathode, these electrons are given to the anions (such as oxygen and water) on the protected metal surface, preventing corrosion.
Cathodic protection is an effective method in preventing rust and is utilized in various industries. This system plays a crucial role in protecting various metal structures, including water pipes, ship hulls, and oil and gas pipelines.
Cathodic protection system is a method used to protect metals against corrosion. This system preserves metal structures by employing an electrochemical reaction between anodes and cathodes. Anodes allow controlled oxidation of the protected metal, while cathodes supply electrons to prevent corrosion. This electrochemical process is managed by a DC current source, preventing natural corrosion of the metal. Cathodic protection ensures the longevity of metal structures like water pipes, ship hulls, and pipelines. Tuncay Engineering is known for providing reliable solutions in this field.
