WebJul 9, 2024 · Corrosion is an electrochemical electron exchange. This means the metal in your pipe loses electrons due to contact with another substance. This wear on a molecular level becomes bigger and bigger and eventually leads to rust, clogs or leaks. Here are some of the more common causes of corrosion in metal pipes: Low PH. Websystems is carbon steel. Where carbon steel pipe is satisfactory, it generally results in the most economical system. The justification for the selection of a more expensive material, however, is usually either a longer life because of reduced corrosion, or an improvement in product quality as a result of reduced contamination (corrosion).
