Corrosion is one of the most important problems in the cooling tower and causes cost loss and reduced efficiency of the tower. The presence of various factors in the tower makes it easy for corrosion to occur in the cooling tower. The presence of water as an electrolyte and also the presence of metals of different types in the tower as cathode and anode provides the basis for creating a chemical cell on a large scale.

Corrosion in steam boilers is caused by chemical and electrochemical reactions of metal with its surrounding environment. The most important corrosion factors in steam boilers are oxygen corrosion, carbon dioxide corrosion, corrosion due to pH drop, alkalinity corrosion, corrosion of hydrolyzable salts and corrosion of organic materials.

Corrosion management is an action to organize corrosion activities and its control methods that has gained a special place in various industries in recent years. With the increasing development of corrosion prevention technologies, the selection of appropriate methods for corrosion control in a specific unit, the need to implement a comprehensive and well-written program called corrosion management, seems essential. Corrosion management is a set of methods and solutions that are applied in a system to prevent corrosion in order to optimize corrosion control methods economically.

Investing in corrosion control is a form of profitability. Ignoring corrosion problems in any industrial and manufacturing unit leads to hidden costs that are impossible to avoid. The first step in corrosion economics is to choose an appropriate method to minimize corrosion costs. These costs can include: production and equipment costs, loss of valuable products, undesirable product appearance, environmental costs, and so on.

The impact of various factors on corrosion damage are: 1_ Design, material selection and process 2_ Lack of necessary instructions 3_ Human error 4_ Poor inspection 5_ Poor layout, installation and coordination 6_ Failure to anticipate unwanted events 7_ Other cases
