Corrosion in various industries

Corrosion in various industries

Due to the climatic conditions and climate diversity of Iran, there are many corrosive areas in the country. The Persian Gulf and the Sea of ​​Oman are among the most corrosive waters in the world.

In central Iran, desert and industrial environments, and in the north, the rainy atmosphere have provided suitable conditions for the intensification of equipment corrosion. As mentioned, corrosion is a phenomenon that occurs in most industries and environments, so no industry can be safe from corrosion. As a result, corrosion management should be given special attention in all industries.

Corrosion Management

Corrosion management is an action to organize corrosion activities and its control methods, which has found a special place in recent seals.

With the increasing development of corrosion prevention technologies, the selection of appropriate methods for controlling corrosion in a specific unit, the need to implement a documented and comprehensive program called corrosion management seems essential. Corrosion management is a set of methods and solutions applied in a system to prevent corrosion in order to economically optimize corrosion control methods.

According to the Bottle Institute, by simply applying existing knowledge and technology, one third of the corrosion costs of industries can be prevented.

Indirect corrosion damages

Another point that is often overlooked is that indirect corrosion damages are in some cases much greater than its direct damages.

For example: Replacing a centrifugal pump impeller not only creates a cost for repairing the part itself, but also causes a flow interruption in the pump opening and closing process and labor costs. In addition, the damage of wasted materials and the resulting pollution cause many problems in terms of safety and the environment.

* Predicting the rate of equipment failure due to corrosion and estimating its costs can prevent losses to a large extent.

**Corrosion management provides preventive methods and takes strategic steps in both non-technical and technical areas.

Corrosion management in non-technical areas

1. Increasing awareness of the huge costs of corrosion and saving on these costs and using existing technologies correctly and reducing costs. Hence, many corrosion problems are the result of lack of awareness of corrosion management and irresponsibility of individuals in the exchange of inspection, repair and maintenance operations of engineering systems.
2. Changing policies, regulations, standards and management practices to reduce corrosion costs
3. Continuous improvement and training of employees to introduce and recognize corrosion control
4. Changing and correcting the misconception and false belief of weaponization against corrosion and making new decisions to prevent this phenomenon

Corrosion management in technical areas

A preventive strategy in technical areas is of great importance.

1. Using advanced design methods to better manage corrosion
2. Improving methods for predicting equipment life and evaluating their performance through familiarization with new corrosion technologies.

Advantages of using corrosion management in industries and factories

In short, the advantages of using corrosion management in industries and factories are:

1. Reducing costs
2. Reducing damage and risks
3. Reducing unplanned machine downtime
4. Increasing the productivity and availability of machines

The role of technology in corrosion management:

Corrosion can be controlled in many industries by using scientific methods and new technological achievements in corrosion management, which requires creating awareness and serious determination to prevent and control corrosion among engineers and corrosion experts.

Proper and accurate application of corrosion management and the use of new technologies in this area can prevent hundreds of billions of tomans of damage in industrial centers annually.

Different researchers and scholars have introduced various types of corrosion as the most important corrosion mechanisms. Therefore, different authors and scholars have not provided a uniform classification for the types of corrosion.
