Claims
- 1. A storage tank system for liquids having secondary containment capability and sufficient integral structural strength to withstand external load forces, comprising:
- (a) a rigid inner storage tank for storing the liquid; and
- (b) a jacket made of a fibrous reinforced resinous material which completely encases the inner storage tank to form a closed space, said jacket having an irregular underside with resin protrusions extending to the inner storage tank to act as force transfer supports thereby causing the jacket to contact the rigid inner storage tank in a random pattern,
- said system further characterized by the jacket being structurally independent from the inner storage tank, yet is in such close proximity to the inner storage tank that said jacket and inner storage tank reinforce one another to achieve the integral structural strength.
- 2. The storage tank system of claim 1 wherein the inner storage tank is a metal tank.
- 3. The storage tank system of claim 1 wherein the inner storage tank is made of a fibrous reinforced resinous material having support ridges circumferentially surrounding the tank and the jacket substantially follows the contour of the inner storage tank's outer surface.
- 4. The storage tank system of claim 3 wherein fiberglass is used to reinforce the resinous material.
- 5. The storage tank system of claim 1 wherein the closed space is less than about 2.0 inches in thickness.
