Corrosion Control Methods and Considerations
Corrosion control involves multiple strategies, including designing systems to avoid moisture and chemical entrapment, using protective coatings with primers, and selecting materials based on galvanic series to prevent dissimilar metal corrosion. External and internal coatings, cathodic protection (using impressed current anodes or galvanic anodes), and environmental control (like adjusting pH) are crucial. Coatings, though effective, are not perfect and require maintenance. Microbial activity can also significantly increase corrosion rates, necessitating careful monitoring and control.
