Abstract
Fire resistant tank apparatus is adapted for transportation and for installation above-ground to receive and dispense a liquid hydrocarbon or hydrocarbons, or the like, and includes a metallic tank assembly having a lightweight, triple hulled, wall structure, defining inner, intermediate and outer walls which are spaced apart. Thermal barrier material is located in certain space between such walls, and in such manner that there is no direct heat conducting metallic path between such walls, as for example the intermediate and outer walls. In addition, fire resistant material may be applied to the outer side or sides of the outer walls and hardened to define a relatively lightweight shell enclosing the tank assembly. The structure resists severe heat invasion in the form of radiation, convection and conduction to maintain liquid hydrocarbon in the innermost tank isolated from such invasion. Also, the structure is bullet resistant.
