Storage tanks are widely used in a diverse range of industries, such as edible oil, petroleum, and more. One of the biggest challenges facing storage tank users is corrosion. It is the gradual degradation of materials, typically metals, through a chemical reaction with their environment. This process often involves the oxidation of the metal, where it reacts with oxygen and moisture, leading to the formation of oxides or other compounds. Corrosion can significantly weaken materials, causing structural failures, leaks, and other issues that can compromise the safety and functionality of equipment.
Corrosion can compromise the integrity and longevity of storage tanks – it can lead to potential leaks, contamination, and costly repairs. The risk of corrosion depends largely on the material used to build the tank and the type of substance being stored inside. Proper maintenance is important or the continued use of these tanks. As one of the best mechanical engineering companies in Kenya, we share some corrosion prevention strategies for storage tanks.
- Choosing the Right Tank Material: The material of the storage tank is one of the most important factors to consider. For instance, some harsh chemicals can only be stored inside stainless steel storage tanks.
- Protective Coatings and Liners:
- Interior Linings: To safeguard the tanks, it is advisable to apply interior linings with materials such as polyurethane, epoxy, and others. Such linings can prevent direct contact between the stored items and the walls of the tank, reducing the risk of corrosion.
- Exterior Coatings: Preventing exterior corrosion is easier and requires painting the tank and using specialised sealants to combat natural weather elements.
3.Cathodic Protection: This is a process where an anode made of a metal that is more easily corroded than the tank metal is introduced inside. The tank contents corrode this sacrificial anode instead of harming the tank. ‘
4. Environmental Controls:
- Moisture Management: Humidity and condensation can accelerate the corrosion process. Proper dehumidification methods and ventilators can be used to prevent moisture buildup.
- Temperature Control: Extreme temperatures can trigger enhanced corrosion, so it is important to regulate the temperature within the tank.
5. Regular Inspection and Maintenance:
Inspection involves visually checking the tank to spot signs of corrosion. Such inspections can help identify and address issues before they worsen. Maintenance of tanks involves cleaning, repairing damaged coatings, and more.
By implementing these corrosion prevention strategies, the longevity and safety of storage tanks can be significantly enhanced.
