Fiberglass Underground Petroleum Storage Tanks

Double Wall Tanks

With more alternative fuels being introduced to the marketplace and steel tank providers decreasing warranties due to corrosion issues, petroleum storage decisions can get complicated. Fiber Glass Systems is here to simplify the problem. FGS manufactures CSI tanks, the finest quality petroleum storage tanks for underground systems. Unlike underground steel tanks, CSI petroleum storage tanks are backed by an industry best 30-year corrosion limited warranty. Our double-wall fiberglass tanks are inherently non-corrosive, safely storing standard petroleum fluids, biofuels and biodiesels, ethanol and ethanol blends, ultra-low sulfur diesel (ULSD), even Diesel Exhaust Fluid (DEF).

Long-term corrosion and material properties testing is done at our Research and Development Center. Laminate testing includes current fuels, blends and other oxygenates, but we do not stop there. We also test alternative products and blends that could be stored in our CSI tanks in the future. As fuel options change, your petroleum storage tank compatibility will not. Many of the newest industry fuels and biofuels are alcohol based. Alcohol blends, including ethanol, increase the likelihood of water in a storage tank, resulting in rust and microbial-induced corrosion (MIC) in steel tanks. The inherent non-corrosive nature of a fiberglass CSI double-wall tank eliminates the possibility of rust on all tank wall surfaces.

Choosing the right fueling location is an important decision, choosing the right petroleum storage tank is imperative. Tank related issues are costly and can lead to environmental catastrophes. Trust the tank that changed the industry, trust a CSI double-wall petroleum storage tank.

Triple Wall Tanks

We also offer a triple-wall fiberglass tank for use in environmentally sensitive areas where tertiary containment is required. The triple-wall tank design provides secondary containment for the standard secondary containment system. Triple-wall tanks offer three levels of containment protection: the proven strength and performance of a primary fiberglass tank, and in the unlikely event that there is a breach, secondary and tertiary walls designed to contain the fuel and prevent any spill into the environment.

Triple-wall petroleum tanks, like single and double-wall models, come with a standard 30-year structural and corrosion limited warranty.
