storage tanks

For many Australian industries, such as government, energy, and mining, maintaining the integrity of their above ground storage tanks is essential for smooth operations. A crucial element in ensuring the longevity and performance of these tanks is the selection of a suitable liner. 

Liners protect the tank’s interior from excessive corrosion and prevent leaks that could lead to contamination or environmental issues. With extensive experience in providing tank design, installation, repairs, and maintenance services, ATM Tanks understands the significance of selecting the right tank lining. This comprehensive guide offers insights into the various aspects of tank liners, their importance, and tips on choosing the ideal option for your above ground storage tanks.

Understanding The Importance Of Tank Liners

Corrosion Prevention

Metal storage tanks are susceptible to corrosion over time, leading to the tank’s structural deterioration. Installing a tank liner provides a barrier between the tank material and the stored liquid, limiting the possibility of corrosion. This subsequently prolongs the service life of the tank.

Leak Prevention

Leaks in tanks can result in several issues, including contamination and environmental hazards. A high-quality tank liner can effectively prevent leakage, ensuring the safety of the stored materials and their surroundings.

Lower Maintenance And Repair Costs

Using an appropriate tank liner reduces the need for expensive, frequent maintenance and repairs arising from corrosion and leakage issues. This leads to long-term cost savings and efficient tank performance.

Variety Of Tank Lining Options

Several materials are available for tank linings, with each offering specific advantages. It is crucial to choose the right lining based on the tank’s application and the type of materials being stored. Some popular lining materials include:

Polyvinyl Chloride (PVC)

PVC liners are widely used due to their versatility and cost-effectiveness. They are appropriate for a variety of applications, including water storage and wastewater treatment tanks. PVC liners offer resistance to a range of chemicals and are available in different thicknesses to suit varying needs.

Ethylene Propylene Diene Monomer (EPDM)

EPDM liners are known for their flexibility and weather-resistant nature. These liners are suitable for large tanks, particularly those storing potable water or needing protection against UV radiation. EPDM linings offer excellent durability, ensuring long-lasting tank performance.

Polyurethane

Polyurethane liners provide excellent chemical resistance, making them an ideal choice for tanks storing aggressive chemicals or harsh substances. Additionally, they are highly flexible and provide superior abrasion resistance, which supports durability and prolongs the service life of the tanks.

Factors to Consider When Choosing a Tank Lining

Compatibility With Stored Material

The tank lining material should be compatible with the liquid to be stored. Consider the compatibility charts provided by lining manufacturers to ensure the right match. Incompatible liners may lead to chemical reactions, causing rapid degradation and failure.

Temperature Resistance

Tanks that store materials at elevated temperatures must have linings that can handle such conditions. Some materials may weaken or lose their effectiveness under persistently high temperatures, so be sure to choose a liner that can endure the specific temperature range required for your application.

Ease of Installation and Repair

Select a tank lining material that is manageable during installation and repair. Some liners, such as PVC, are relatively simple to install, whereas others may be more labour-intensive or require specialised equipment.

FDA Compliance (If Applicable)

For above ground tanks storing potable water or food products, the chosen lining material must comply with Food and Drug Administration (FDA) standards. Verify the FDA compliance of liners to ensure the safety of the stored materials for human consumption.

Durability And Lifespan

When choosing a tank liner, it is essential to take its durability and expected lifespan into consideration. Opt for materials that provide excellent resistance to wear and tear and have a proven track record in the industry.

Conclusion

The use of appropriate tank linings plays a vital role in maintaining the integrity and longevity of above ground storage tanks. Various lining materials offer distinct advantages, and understanding their characteristics is essential to making an informed decision.
