Causes of Corrosion

Causes of corrosion are also explained in the article "6.8 Corrosion in Production Operations”. As discussed there, the causes of corrosion in production operations vary and are dependent on the stages of the production operations. One of the causes of the corrosion in the production materials is the difference in temperature. For example, in the pipelines, the temperature can be as high as 350°F and low as 185°F from the time of formation of the product to the time of coming out of the product. The main and most important cause of the corrosion is acidity. This can also be called Acid Gas Corrosion. Acidity plays an important role in the process of corrosion. In the environment containing moisture, the presence of gases such as carbon dioxide helps in the formation of acids. With the increase in concentration of gases like this, the degree of acidity also increases. The pH value decreases with the increase in acidity and as a result, the rate of corrosion increases ("6.8 Corrosion in Production Operations”).
