Demystifying Tank Liners: Raven Tanks’ Comprehensive Answers

Tank liners are indispensable components in industrial tanks, safeguarding the secure storage of chemicals, wastewater, and various liquids. However, queries often arise about tank liners, their functions, and the intricacies of their installation. This article delves into the most frequently asked questions about tank liners, offering detailed insights. 


What Is a Tank Liner? A tank liner is a membrane strategically installed within a tank, creating a protective barrier between the stored liquid and the tank’s internal surface. Diverse materials, including polyurethane, PVC, and rubber, can be employed to craft these liners. 

Tank liners play a pivotal role in shielding tanks from corrosion, averting leaks, and ensuring the secure containment of stored liquids. 


Why Do You Need a Tank Liner? The necessity of tank liners stems from their pivotal role in shielding both the tank and the stored liquid. Absence of a liner exposes the tank’s surface to corrosion, potentially resulting in leaks that can contaminate the stored liquid. 

Tank liners act as a shield, creating a barrier between the liquid and the tank’s surface, thereby preventing corrosion and leaks. They can be customized to withstand extreme temperatures, making them suitable for storing liquids at varying temperatures. 


What Are the Different Types of Tank Liners? Various tank liners cater to distinct needs, each possessing unique properties and advantages. Common types include: 


  • Polyurethane liners: Renowned for durability and resistance to chemicals and abrasion. 
  • PVC liners: Easily installed and adaptable, preferred for smaller tanks. 
  • Rubber liners: Resistant to high temperatures and weather exposure. 
  • Epoxy liners: Widely used for water storage due to rust resistance and applicability to metal and concrete surfaces. 
  • Fiberglass liners: Robust and durable, often employed for larger tanks. 


How Do You Choose the Right Tank Liner? Selecting the appropriate tank liner hinges on factors such as the stored liquid type, tank size, and environmental conditions. For corrosive liquids, polyurethane or rubber liners may be optimal, while larger tanks might benefit from fiberglass liners. 

Professional consultation is advisable to ensure the selection of the right tank liner aligns with specific needs. 


Can You Install a Tank Liner Yourself? While self-installation is plausible, it is not recommended. Correct installation is paramount to ensure the tank liner offers the necessary protection for both the tank and the stored liquid. Inaccurate installation can lead to leaks and other issues, making professional installation the preferred choice. 


How Long Will a Tank Liner Last? The lifespan of a tank liner is contingent on factors like liner type, environmental conditions, and the stored liquid. On average, tank liners endure between five to ten years, though some can last up to two decades with proper maintenance. 


Conclusion In the realm of industrial tank operations, tank liners play a crucial role in safeguarding tanks, their contents, and ensuring worker and environmental safety. Thorough consideration of the liquid being stored and environmental factors is vital when selecting a liner. Opting for professional installation enhances accuracy and maximizes the liner’s lifespan.
