Why Proper Tank Liner Selection is Key to Longevity and Safety

What is a Tank Lining?

 

A tank lining is a protective barrier designed to shield the substrate material from chemical damage within a tank. A high-quality lining creates a completely impermeable seal, adheres securely to the substrate, fills any gaps, and offers cost-effective corrosion protection, preventing expensive failures.

According to federal regulations, tanks with capacities under 110 gallons must have proper linings to ensure the safe containment of chemicals and prevent leaks in water storage tanks.

For decades, the oil and gas industry has identified corrosion in storage structures as a leading cause of tank failures and leaks. To safeguard their assets and extend tank lifespan, owners commonly implement corrosion control measures, including high-performance tank linings.

 

Effects of Corrosion and how to Prevent it

 

Corrosion is the gradual breakdown of materials due to chemical reactions with their environment. This process affects metals, plastics, and other materials that are incompatible with specific chemical compounds, leading to a loss of strength, aesthetic degradation, and increased permeability to liquids and gases. One effective way to prevent corrosion is by applying a high-performance, corrosion-resistant coating.

Many advanced coatings offer excellent resistance to corrosion and abrasion. However, only a few specialized coatings provide strong chemical resistance against aggressive substances such as acids, alkalis, gases, solvents, and oxidizers, as well as extreme temperatures associated with their storage and transportation.

Protecting both the interior and exterior surfaces of metal tanks is essential. While environmental exposure can accelerate steel corrosion, many stored substances can also contribute to surface deterioration. Without proper protection, corrosion can lead to perforations, internal damage, and costly repairs. In addition to repair costs, tank owners may face production losses, environmental risks, and regulatory compliance issues due to inadequate corrosion protection.

When choosing a coating, the right criteria must be considered to provide the most cost-effective corrosion protection. Contamination of the stored product and tank deterioration are more likely if an appropriate coating is not selected and applied.

 

Factors to Consider When Choosing Chemical Tank Liners

 

1. The Type of Chemicals in the Storage Tanks

Different chemicals will have different reactions in your tanks. It also depends on the type and material of tanks used in your plant. The majority of aboveground or underground tanks used for industrial purposes are made of steel or fiberglass. This means that the majority of the chemicals will react with the tank walls, resulting in corrosion. Hydrochloric acid and peracetic acid are two examples of common corrosive chemicals. To safely contain chemicals, all plants that deal with chemicals should use chemical liners for their industrial tanks. One type of chemical liner may be more corrosion-resistant than another, so consider the chemicals you work with before purchasing a tank liner.

2. Compliance with the State and Federal Regulations

Setting operational standards for critical industries is a procedure for the federal and local governments. Some of the industries that are regulated are chemical plants and water plants. The EPA established a list of 140 chemicals that require owners to submit a risk management plan to federal regulators when storing the chemicals in sufficient quantities. Before you buy a chemical liner, make sure you’re in compliance with federal and state regulations.

Because of the high risk involved in storing corrosive chemicals in bulk, it makes sense for authorities to impose regulations. Most of these chemicals produce highly flammable hydrogen gas when they react with metals at high temperatures. This endangers not only you and your employees but also the surrounding environment. High-quality industrial tank liners aid in corrosion prevention, preventing catastrophic accidents.

3. Custom Tank Liners

It is unlikely that all of the tanks in your plant are the same size, height, and shape. As a result, there is no such thing as a one-size-fits-all chemical liner. All chemical liners for your plant’s chemical tanks must be made to order. Tank liners should cover every inch of the tank to prevent chemicals from corroding the tank’s interior surface. A tank liner that does not cover the tank’s walls proportionally may leave some areas exposed, resulting in corrosion. As a result, your stored chemicals may become contaminated, and your tanks will deteriorate due to the rapid corrosion rate. To avoid these negative effects, use customized chemical liners in each of your plant’s tanks.

4. Expert Installation

Because of the high precision required, tank lining installation is quite technical. As a result, you must ensure that you have a team of experts who are experienced in tank liner installation. In most cases, the company that provides you with liner products should also be able to install your chemical liner. Given the high cost of some of these chemical liners, you must ensure that they are properly installed. You don’t want to have to replace your tank liners too frequently as a result of poor installation. If the chemicals reached the interior surface of the tank and caused a reaction, a poorly installed chemical liner would cause even more damage. This necessitates professional installation.

 

 

Every plant manager understands the importance of chemical liners. A chemical liner will protect your stored chemicals as well as your tanks. When stored corrosive chemicals are mishandled, they endanger your entire plant and the surrounding environment. The use of high-quality chemical tank liners ensures that chemicals are kept in perfect condition. Finally, when you use industrial tank liners, your chemical tanks will last longer.

The above factors will help you decide why you need a tank liner. But if you’re still unsure about your decision, it helps to talk to an expert. Our staff can help point you in the right direction. So call us today.
