Extending the Lifespan of Underground Storage Tanks: Steel vs. Fiberglass
Underground storage tanks (USTs) play a critical role in fuel storage, industrial processes, and various commercial applications. To ensure the efficiency, safety, and longevity of USTs, proper material selection and maintenance are essential. The two primary materials used for UST construction—steel and fiberglass—each offer unique benefits and challenges. Understanding these differences can help businesses make informed decisions when selecting or maintaining their tanks.
Below, we’ll explore key factors to consider when choosing a UST. For help with installation and removal, lining & coating, compliance testing, and related services, contact Lutz Tanks for help from trusted professionals with over 100 years of experience in the industry.
Steel USTs: Durable and Time-Tested
Steel has long been a preferred material for underground storage tanks due to its strength and durability. With proper maintenance, steel tanks can last decades, making them a cost-effective choice for many applications. Advantages of steel USTs include:
- Strength and Durability: Steel tanks are highly resistant to impact and can withstand external pressures from soil or groundwater. This structural integrity makes them a reliable choice in demanding environments.
- Coating Options: Modern steel USTs often come with protective coatings, such as epoxy or polyurethane, which help prevent corrosion and extend the tank’s lifespan. Herbert Lutz & Company is certified to perform lining inspections and can line and coat your existing tanks.
- Recyclability: Steel is 100% recyclable, making it an environmentally friendly option when tanks are decommissioned.
Despite their strength, however, steel tanks are susceptible to corrosion, especially when exposed to moisture or corrosive substances. To mitigate this risk, regular inspections and maintenance are crucial. Advanced technologies, such as cathodic protection systems, can also be implemented to safeguard steel USTs from corrosion over time.
Fiberglass USTs: Corrosion Resistance and Flexibility
Fiberglass-reinforced plastic (FRP) tanks have become increasingly popular due to their natural resistance to corrosion. Fiberglass is a non-metallic material, making it ideal for storing a wide range of substances without the risk of rust or chemical degradation. Advantages of fiberglass USTs include:
- Corrosion Resistance: Unlike steel, fiberglass does not rust, making it an excellent choice for environments with high moisture levels or chemically aggressive soils.
- Lightweight and Easy Installation: Fiberglass tanks are lighter than steel tanks, which simplifies transportation and installation. This can result in lower upfront costs for installation projects.
- Compatibility with Multiple Substances: Fiberglass tanks are versatile and compatible with a variety of chemicals, including biofuels and ethanol blends, which can be corrosive to steel.
While fiberglass tanks are resistant to corrosion, they are not immune to damage. Fiberglass is more brittle than steel and can be prone to cracking or structural failure under extreme stress. Regular inspections are still necessary to identify and address potential issues before they compromise the tank’s integrity.
Comparing Longevity: Steel vs. Fiberglass
The lifespan of a UST depends on multiple factors, including the material, environmental conditions, and maintenance practices. With proper care, steel tanks can last 30 to 40 years or more, while fiberglass tanks typically have a similar lifespan. However, the maintenance requirements differ. As noted, steel tanks require regular monitoring for corrosion, application of protective coatings, and potential installation of cathodic protection systems. For their part, fiberglass tank maintenance involves routine inspections to detect cracks, leaks, or structural damage.
Choosing between steel and fiberglass often comes down to the specific needs of the site, the stored substance, and the long-term operational goals.
Best Practices for Extending UST Lifespan
Regardless of the material, adopting proactive measures can significantly extend the life of your underground storage tanks:
- Regular Inspections: Routine checks for signs of corrosion, cracking, or leakage can help identify potential problems early.
- Maintenance of Protective Systems: Ensure that cathodic protection systems (for steel tanks) and coatings are functioning properly.
- Compliance with Regulations: Adhere to state and federal regulations governing USTs in your state. Staying compliant helps prevent environmental hazards and costly fines.
- Timely Repairs: Address any identified issues promptly to prevent small problems from escalating into major failures.
- Professional Servicing: Partner with a reputable UST service provider, such as Herbert Lutz & Company, to handle installation, removal, and maintenance needs.
