Discover the Power of Double Wall Fuel Storage Tanks

What is a double wall fuel storage tank?
A double wall tank features an inner tank that holds the fuel, surrounded by a larger outer tank or shell that acts as a secondary containment barrier.
How do double wall tanks provide enhanced safety?
They offer redundant containment. If the inner tank leaks, the outer wall will contain the fuel, preventing environmental spills and potential hazards.
Why are double wall tanks better for environmental protection?
By containing leaks within the outer wall, they significantly reduce the risk of fuel contaminating soil and groundwater, protecting sensitive ecosystems.
Are double wall fuel tanks required by regulations?
Many regions and industries mandate secondary containment, making double wall tanks a common solution to comply with environmental and safety regulations.
What materials are typically used to construct these tanks?
They are commonly constructed from steel (carbon steel, stainless steel) or fiberglass reinforced plastic (FRP), depending on the application and stored fuel type.
Can double wall tanks be installed both aboveground and underground?
Yes, double wall tanks are available in designs suitable for both aboveground (AST) and underground (UST) installations, offering flexibility for different site requirements.
Yes, double wall tanks are available in designs suitable for both aboveground (AST) and underground (UST) installations, offering flexibility for different site requirements.
The space between the inner and outer walls (interstitial space) can be monitored using sensors or visual indicators that detect the presence of liquid or vapor from a leak.
What kind of monitoring systems are used with double wall tanks?
Monitoring systems can range from simple visual indicators or dipsticks to advanced electronic sensors connected to alarms or monitoring panels.
