Fiberglass Underground Fuel Storage Tanks: A Guide for the Users

When it comes to reliable, safe, and long-term storage solutions for industries fiberglass tanks are second to none.

With technological advancements, these vessels are getting upgraded with better designs and features. Manufacturers comply with stringent industry protocols to ensure their high-performance, safety, and longevity.

Fiberglass underground fuel storage tanks is the latest invention that is specially crafted to keep highly corrosive and inflammable liquids such as ethanol-blended fuels (E10, E15, E85), biodiesel fuels, petroleum products, and ultra-low sulfur diesel.

What are Fiberglass Underground Fuel Storage Tanks?

Fiberglass underground fuel storage tanks are large vessels used for meeting storage demands in industries.

They are manufactured from polyester resins that are strengthened with glass fiber generally installed beneath the ground.

Fiberglass underground fuel containers were first introduced in 1960s. Since then they have gained popularity.

As we entered into the 1980s major oil and fuel companies started to realize the advantages of using fiberglass tanks over steel vessels.

Features of Fiberglass Underground Fuel Storage Tanks

With the advent of technology, new features are being added to the latest models of underground fuel vessels. This has facilitated users and plant operators of chemicals alike.

Double & triple wall coating: Double-wall layered fiberglass tanks and vessels have the capacity to assess the interstitial space for reliability hydraulically or with sensors. This makes the units robust, corrosion resistant and leak-proof.

In recent times, triple-walled fiberglass fuel underground tanks have become popular due to their enhanced protection.

Secondary Containment: Secondary containment is described as an area that captures the entire contents of the largest tank in the containment area when there is an abrupt leak or spill of the chemicals and acids.

Sizes: Modern units are designed in such a way that they can hold up to 50,000 gallons of liquids.

Their sizes range from 4-foot diameter to 12-foot diameter. Industries utilize those fiberglass fuel tanks with 10-foot diameter as they can accommodate or store up to 50,000 gallons of liquids and chemicals and can also be used for wastewater treatment applications.

Multi-compartments: Multiple compartments in fiberglass fuel industrial storage tanks facilitate in keeping multiple products in the same tank instead of storing different products separately in smaller tanks. This helps in decreasing operation costs.

Advantages of Fiberglass Underground Fuel Storage Tanks

Corrosion resistance: The biggest advantage of using fiberglass underground fuel storage tanks is that they are not susceptible to internal corrosion caused by aggressive microbial-induced corrosion. As a result, you can store highly-corrosive gasoline, petroleum, and ethanol-blended fuel products easily on them.

Fuel compatibility: Fiberglass fuel tanks have unique fuel compatibility while the same cannot be said about steel and alloy tanks. Modern units are UL-tested and UL-listed which makes them compatible with ethanol and gasoline storage.
