Abstract
A tank for use in storing volatile liquids and, in particular, petroleum distillates, includes a fiberglass outer wall lined with a metal foil liner that substantially covers the entire interior surface of the fiberglass tank. In a preferred method of constructing a tank, a lay-up mandrel has a foil end cap placed over a first end thereof and pressed to fit closely the exterior surface topography of the mandrel. A strip of metal foil is laid down on the mandrel overlying at least a portion of the metal foil end cap and the metal strip is wound in a helical fashion such that the adjacent coils of the helix overlap one another until the mandrel is essentially completely covered by the metal foil. Fiberglass resin and glass fibers are then laid down over the metal foil and cured in place. The mandrel is then removed, leaving a foil-lined fiberglass tank.
