Definition - What does Corrosion Control mean?
Corrosion control refers to measures that are implemented in various fields to control corrosion in:
This consists of different corrosion monitoring and control techniques that can be utilized by industries to solve corrosion problems according to their requirements. With such measures, the harmful effects and negative consequences of corrosion can be avoided.
Corrosionpedia explains Corrosion Control
Corrosion can lead to countless environmental issues. For example, ships, tankers and pipelines are often subjected to the dangerous corrosion effects. Corroded water systems can also contaminate drinking water. These serve as threats to the environment and mankind, so effective corrosion control methods should be implemented to prevent the damaging effects of corrosion. Corrosion can be controlled in several ways:
- Cathodic protection (CP) - This technology utilizes direct current to counteract a metal structure's corrosion, in structures like gas pipelines and storage tanks. This helps prevent the onset of corrosion and even stop it from worsening.
- Linings and coatings - These serve as the main tools for fighting corrosion. They are usually applied in combination with CP to achieve the highest level and most cost-effective corrosion protection.
- Corrosion inhibitors - These are substances that, when placed in a certain environment, reduce the corrosion rate of that environment to certain materials like metal. These can be beneficial in extending the lifespan of equipment and preventing failures as well as system shutdowns. Corrosion inhibitors can also prevent heat transfer loss, contamination and preserve the aesthetic appearance of the structures.
- Selection of materials - This refers to choosing materials that are corrosion resistant like special alloys, plastic and stainless steel to improve the lifespan of structures.
