Issue 20: Corrosion

Corrosion is one of the largest causes of plant and equipment breakdown in the process industries and is a dangerous and extremely costly problem which can result in loss of primary containment and even electrical fires due to corroded electrical contacts. Corrosion is an electrochemical reaction that appears in several forms such as chemical corrosion and atmospheric corrosion. When acidic substances come in contact with metals such as iron or steel rust begins to form. Rust is the result of corroding steel after the iron particles have been exposed to oxygen and moisture and if not managed effectively can have catastrophic consequences.
