How to reduce repair costs by 80%? Discover cathodic protection solutions

Corrosion is a common problem for most equipment and metallic structures exposed to hostile environments. Not only can it cause equipment failure, but it can also be costly in terms of repair and replacement. If left unchecked, it can lead to severe damage and pose a danger in certain industries, such as petrochemicals and hydrocarbons, where it can cause leaks or explosions.

Cathodic protection, as a reliable solution, is a method for preventing corrosion in buried and submerged metallic structures. It allows for the prolongation of the life span of structures and yields significant benefits to the safety and reliability of installations, as well as a considerable reduction in total costs over the lifespan of assets.

The principle is based on converting active areas of a metallic surface into passive ones, i.e., converting them into the cathode of an electrochemical cell. By supplying impressed or galvanic current, the metal potential is reduced, corrosion attack decreases, and protection against corrosion is achieved.

Applications of Cathodic Protection

Cathodic protection is commonly used to protect numerous structures against corrosion, such as pipelines, tanks, vessels, ships, piles, docks, marine floaters, underwater equipment, and a large number of other applications, basically all buried or submerged metal structures. Additionally, it is a flexible solution that can be adapted to the specific needs of each client.

How to choose the appropriate cathodic protection method?

The choice of the appropriate cathodic protection method depends on several factors, such as the composition of the metal structure, the environment in which it is located, and the effectiveness of the method in question. Cathodic protection methods include sacrificial anode protection and impressed current protection.

What are the advantages and disadvantages of cathodic protection?

Cathodic protection offers several advantages, such as a long service life, relatively simple installation and maintenance, and the ability to protect large areas of metal. However, it also has some disadvantages, such as the need for monitoring, periodic maintenance, and the possibility of system failures.

One of the main benefits of cathodic protection is that it can significantly reduce repair and maintenance costs, as well as downtime in industries that depend on these structures. This is because corrosion is one of the main causes of deterioration in metal structures, and its prevention through cathodic protection can extend the life of these structures.

Controlling corrosion through cathodic protection prevents the need to replace or repair parts of a structure that have been damaged due to corrosion, resulting in a reduction in repair and maintenance costs in industrial settings.

Where is cathodic protection used in the industry?

Cathodic protection is used in a wide variety of industries, such as the oil and gas industry, marine, energy, and chemical industries.

1. In the oil and gas industry, it is used to protect pipelines and storage tanks from corrosion caused by saltwater and other corrosive chemicals.
2. In the marine industry, it is used to protect ships and other metal structures from corrosion caused by saltwater.
3. In the energy industry, it is used to protect metal structures in power plants, such as pipelines and cooling towers.
4. In the chemical industry, it is used to preserve metal structures used in the production and storage of corrosive chemicals.
