Corrosion Resistant Liners: Best Practices

Corrosion Resistant Liners: Best Practices

With proper planning, you can minimize repairs and extend the life of corrosion resistant liners on vessels and storage tanks.

Problems can emerge at any time. However, you can help avoid costly mistakes or oversights by following a series of best practices.

Here are some quick reminders and tips that your workers can keep in mind to protect against highly aggressive chemicals and potential spills that could adversely affect the environment:

1. Match the lining with the type of storage tank.

Do you need to protect concrete or steel storage tanks? For example, with concrete, you’ll need to look for areas with moisture when installing a rubber lining. Steel thickness and vessel temperatures are key variables. The substrate surface should not have contaminants like oil and grease.

2. Ensure that the contents match the lining.

Do you store water or harsh chemicals like hydrochloric and hydrofluoric acid?

3. What is your inspection schedule?

Are existing and new workers properly trained on when to inspect and how to assess the condition of tanks and linings?

4. How do you look for damage?

For example, leak detection can involve “sesting,” a method that helps identify pinholes in tank linings.

5. When does it make sense to maintain or repair rubber linings?

If they’re not timed well, repairs can be costly if the vessel or storage tank can’t be used as planned. How can you schedule repairs when it’s the least disruptive (i.e. weekends)?

General repairs to a rubber lining of less than 18” can be executed with a simple fill and overlay using appropriate tools. Learn more on repair versus replacement lining scenarios.

6. Understand the limitations of alternative materials.

You want to be careful if you consider other liners, such as fiberglass that can crack over time. Spray/paint applications may be too thin for the storage tank contents (multiple applications may be needed).

With the right corrosion resistant liners – and consistent inspections – you can protect your assets from damage, workers from dangerous situations and the environment from exposure.
