Underground Steel Tanks
Petroleum and Chemical Storage Tanks
Underground steel storage tanks are designed to stand up to the rigors of an underground environment. Our tanks can store a variety of petroleum products and other fuel storage systems.
All of our tanks meet or exceed the U.S. EPA's regulations for underground storage of petroleum and chemicals. They are also constructed, tested, and labeled in accordance with Underwriters Laboratories, Inc. standards:
- UL-58: Standard for Safety Steel Underground Tanks for Flammable and Combustible Liquids
- UL-1746: External Corrosion Protections Systems for Steel Underground Tanks
Steel Storage Tank Standard Features:
- Capacities from 240-50,000 gal
- Steel Thickness from 10 gauge to 1 1/4"
- Exterior Full Fillet Lap Joints to add "ribbed" strength
- Striker Plates to protect the internal surface
- Seam Inspection
- 5 psi Factory Air Test
Petroleum & Chemical Underground Tank Product Variety
Double-Wall Steel Storage Tank:
The Double-Wall Steel Storage Tank meets or surpasses all the current UL Standards as it combines the strength of steel with the protection of a polyurethane coating. Water Storage Tanks also offers an STI standard 10-year limited warranty.
Available as single or double wall, these tanks are superior to Fiberglass Reinforced Polyester coating and more resistant to incidental damage.
Underground Storage Tank:
This tank features a pre-engineered corrosion protection system that stands the test of time. The Underground Storage Tank is the most successful underground tank technology ever developed. It has a a unique three-way protection system:
- 100% solids polyurethane dielectric coating
- electrical isolation
- factory-installed cathodic protection system using sacrificial anode. The Underground Storage Tank has a maximum 120 degrees F temperature use rating, a standard 10 year warranty, and is available in single or double wall.
Double Wall Underground Tank:
The Double Wall Underground is one of the toughest underground steel storage tanks offered. It features a strong solvent/tar-free dielectric coating of high solids polyurethane.
It out-performs fiberglass reinforced polyester tanks, requiring no artificial reinforcement and can safely store all motor fuels and biofuels.
On a total installed-cost basis, cost is less than any other unmonitored tank configuration on the market today and has a standard limited 10-year warranty.
High RES Tank:
Our top-of-the-line residential heating fuel storage tank feature a polyurethane coating that protects against corrosion making it superior to asphaltum/primer coated tanks.
Available in Double or Single-Wall, double-wall tanks are available with 305 or 360 degree containment. High RES tanks set the standards by which all other residential fuel tanks are measured.
Hot Shot Tank:
The HotShot is designed specifically for the safe storage of heavy residual fuel oils like No. 6 fuel oil used for steam boilers and power generators. It allows the oil to easily flow for maximum burning efficiency.
The surface is protected against corrosion, has a high temperature resistive exterior coating, and a cathodic protection system.
Available as single or double-wall, this underground steel storage tank has a 5-year limited warranty.
The Titan tank is one of the most technologically advanced underground storage tanks available.
It features patented "fusion bond" technology to create a leak and damage-proof outer thermoplastic tank.
The Titan assures 100% secondary containment, motor/biofuel compatibility, reduced installation cost, and a 10-year limited warranty.
We also offer plastic chemical storage tanks including conical bottom tanks, brine tanks, tapered tanks, vertical tanks, rectangular tanks, and more.
