Underground Double-Wall Fuel Tanks
Underground double-wall fuel tanks with secondary containment and a monitorable interstitial space for enhanced protection and early leak detection.
APMI manufactures underground double-wall fuel tanks consisting of an inner steel tank enclosed by an outer steel shell, providing an additional level of protection and secondary containment.
The interstitial space between the two walls can be connected to a dedicated monitoring and leak-detection system, supporting early detection and helping protect the surrounding site and soil.
Tank capacity, dimensions, connections and protective coating systems are specified according to project requirements and site conditions. Manufacturing includes steel forming and welding, dimensional and weld inspection, integrity testing of the inner tank and interstitial space, surface preparation and coating before delivery.
The tanks can also be integrated with leak-detection systems, cathodic protection, fuel piping, transportation and installation services according to the scope of each project.
