ABSTRACT:
A cylindrical-shaped storage tank with substantially flattened ends is jacketed in a manner which results in storage tank system capable of holding detecting liquid or being placed under nonatmospheric pressure without structural damage. The storage tank initially has end plates mounted on its flattened ends. Thereafter, a separating agent is applied over the side walls of the storage tank, a layer of fibrous reinforcing material applied on the separating agent and the end plates, and a resinous material applied. The resultant jacket is independent from the side walls of the inner tank. True secondary containment is provided by the end plates and jacket. A fail safe containment storage tank system is provided by the use of independent leak detection means to monitor the closed space between the storage tank and end plates and the closed annular space between the storage tank and jacket for tank or jacket leakage.
