Storage Tank

Above ground storage tanks (ASTs) play a vital role in numerous industries, from oil and fuel storage to water management and beyond. Ensuring the structural integrity and safety of these tanks is of paramount importance, given that leaks or spills can result in environmental damage, health risks, and considerable financial loss.

One of the most effective ways to protect and prolong the life of your ASTs is through the use of tank liners. These liners provide an additional barrier against corrosion, leaks, and contamination, keeping your tanks functioning efficiently and safely for an extended period.

In this blog, we will delve into the various benefits of tank liners for above ground storage tanks, discussing how they contribute to the longevity and safety of your ASTs. We will offer insights into the different types of tank liners available, such as flexible membrane liners and rigid plastic liners, as well as their compatibility with an array of stored materials. Moreover, we will provide guidance on selecting and installing tank liners, considering factors such as tank dimensions, materials, environmental conditions, and budget constraints.

Benefits of Tank Liners for Above Ground Storage Tanks

Investing in tank liners can deliver several advantages for businesses utilising above ground storage tanks. These benefits include:

1. Corrosion resistance: Tank liners provide a protective barrier against corrosive substances, preventing damage to your tanks and reducing the risk of leaks or structural failure.

2. Leak prevention: The installation of a tank liner reduces the likelihood of leaks, eliminating the potential for costly clean-ups, fines, and negative environmental impacts.

3. Contamination prevention: Tank liners prevent stored materials from coming into contact with contaminants in the tank wall, ensuring the stored substances maintain quality and value.

4. Prolonged tank life: By safeguarding against corrosion, leaks, and contamination, tank liners can extend the service life of your ASTs and reduce the need for premature tank replacements.

Types of Tank Liners and Compatibility

There is a variety of tank liners available to accommodate different storage requirements, materials, and tank constructions:

1. Flexible membrane liners: These liners are made from cost-effective materials, such as polyethylene (PE), polyvinyl chloride (PVC), or ethylene propylene diene monomer (EPDM). Flexible membrane liners can be customised to fit any tank shape and are suitable for storing water, fuel, and chemicals, depending on the liner material.

2. Rigid plastic liners: Constructed from fibreglass reinforced plastic (FRP) or other rigid polymers, these liners offer excellent corrosion resistance and structural strength. Rigid plastic liners are ideal for applications requiring a more robust and durable lining solution, such as for high-temperature or high-pressure storage.

3. Spray-on linings: A less common option, spray-on linings are applied directly onto the tank wall, creating a seamless and impermeable barrier. While typically more expensive than other liner types, spray-on linings can be beneficial for irregularly shaped tanks or where conventional liners may not provide the desired level of protection.

When selecting a tank liner, compatibility with the stored material is crucial, as chemical reactions between the liner and substance can lead to liner degradation and potential failure. Ensure the chosen liner material is suitable for the specific materials stored within your tank.

Selecting and Installing Tank Liners

When determining the most suitable tank liner for your ASTs, consider the following factors:

1. Tank dimensions and shape: Measure your tank accurately to ensure the liner fits correctly, leaving no gaps or vulnerabilities. A correctly fitting liner is essential for maximum effectiveness.

2. Material compatibility: As mentioned earlier, verify that the chosen liner material is compatible with the stored substance to prevent chemical reactions and premature liner degradation.

3. Environmental factors: Consider temperature, humidity, and local weather conditions, as these can impact the liner’s performance and durability. Select a liner capable of withstanding the specific environmental conditions at your site.

4. Budget: While it can be tempting to opt for the cheapest option available, consider the long-term benefits and potential cost savings of investing in a higher-quality liner. When making your decision, weigh the initial purchase and installation costs against ongoing maintenance, repair, and replacement expenses.

Proper liner installation is essential to ensure its effectiveness and longevity. It is highly recommended to work with a trusted professional for installation, as improper fitting can lead to leaks, damage to the liner, and potential tank failure.
