Why would Cathodic protection fail?
There are several reasons why cathodic protection systems can fail. Some common causes of failure include:
Inadequate design: If the cathodic protection system is not properly designed for the specific application, it may not provide sufficient protection against corrosion.
Poor installation: If the cathodic protection system is not installed correctly, it may not function properly and may not provide sufficient protection against corrosion.
Lack of maintenance: Cathodic protection systems require regular maintenance to ensure they are functioning properly. If the system is not properly maintained, it may fail to protect the metal structure from corrosion.
Electrical issues: Cathodic protection systems rely on an electrical current to function. If there are problems with the electrical circuit or the power source, the system may not work properly.
Damage to the system: Cathodic protection systems can be damaged by physical impact, such as from vehicles or construction equipment. If the system is damaged, it may not provide sufficient protection against corrosion.
Changes in the environment: The effectiveness of cathodic protection systems can be affected by changes in the environment, such as changes in the soil or water chemistry. If the environment changes significantly, the cathodic protection system may not work properly.
By understanding these potential causes of failure, it is possible to design and maintain cathodic protection systems to ensure they are effective at protecting metal structures from corrosion.
