December 21, 2023

Tank liners play a crucial role in protecting storage tanks and their contents. However, there may come a time when you need to remove an old or damaged tank liner to ensure the continued functionality and safety of your tanks. If you find yourself in this situation, understanding the process of removing an old tank liner is essential. In this blog, we’ll guide you through the steps involved and highlight important considerations to keep in mind.

Knowing When It’s Time to Remove an Old Tank Liner

Before diving into the removal process, it’s important to recognize when an old tank liner needs to be replaced. Signs that it’s time for removal include:

  • Visible Damage: If the liner is visibly cracked, torn, or peeling, it’s likely compromised and needs replacement.
  • Leakage: Any signs of leaks or seepage indicate that the liner is no longer providing an effective barrier.
  • Chemical Deterioration: If the liner’s material has deteriorated due to exposure to stored substances, it’s essential to remove and replace it.
  • Reduced Efficiency: A liner that’s no longer providing adequate protection can lead to inefficiencies in tank operation and potentially compromise the contents.

Step-by-Step Guide to Removing an Old Tank Liner

Step 1: Empty the Tank

Before starting the removal process, ensure the tank is completely emptied of all contents. Properly dispose of any liquids or substances according to regulations.

Step 2: Safety Precautions

Wear appropriate personal protective equipment (PPE) to safeguard yourself from potential hazards. This may include gloves, goggles, and respiratory protection.

Step 3: Assess the Liner

Inspect the liner’s condition to determine the best approach for removal. Take note of any areas that require extra attention due to damage or adhesion issues.

Step 4: Cut and Remove

Using appropriate cutting tools, carefully cut the liner into manageable sections for removal. Take care not to damage the tank’s interior surface during this process.

Step 5: Peel or Scrape

Depending on the liner material and its adhesion, you may need to peel or scrape the liner from the tank’s interior. Use tools suitable for the liner material to ensure effective removal.

Step 6: Clean the Interior

Once the liner is removed, thoroughly clean the tank’s interior to remove any adhesive residue, debris, or contaminants.

Step 7: Surface Preparation

Prepare the tank’s interior surface for the installation of the new liner. This may involve sanding, smoothing, and ensuring the surface is clean and free from imperfections.

Important Considerations

1. Safety First: Prioritize safety throughout the removal process. Use appropriate PPE and follow safety guidelines to prevent accidents and exposure to harmful substances.

2. Proper Disposal: Dispose of the old liner material and any waste following regulations and guidelines to minimize environmental impact.

3. Choose a Reputable Provider: If you’re replacing the old liner, choose a reputable tank liner provider that offers high-quality materials and installation services.

4. Consult Professionals: If you’re unsure about any aspect of the removal process, consider consulting professionals who specialize in tank liners to ensure proper removal and replacement.
