ABSTRACT:
A reinforced plastic tank and method for producing the same, in which a steel plate base is provided for minimizing the bottom deflection of the tank under hydrostatic pressure when buried under ground. The base has a plate member with an annular flange extending outwardly from the top surface thereof. A plastic cup is disposed within the area surrounded by the flange, and an epoxy adhesive is injected between the cup and the steel plate and flange to adhere the cup to the steel. The side wall of the cup extends past the edge of the flange. The base assembly is then mounted on a mandrel and the fiberglass side wall is formed over the steel flange and the exposed side wall of the cup, and extends from the steel base to the desired height of the tank.
