PROCESS FOR THE PRODUCTION OF PLASTIC LAYERS

Tank construction and method of manufacture

A tank construction including an outer shell of steel material comprised of two half members welded together. The half members are formed by a deep drawing process. An inner shell of non-corrosive material is cast inside the outer shell by a rotational casting procedure with the external surface of the inner shell located adjacent the internal surface of the outer shell. The inner shell of non-corrosive material provides a substantially leak-tight liner for the outer shell to thus prevent contact between the contents of the tank and the outer shell. The rotational casting of the inner shell inside the outer shell is accomplished by charging the outer shell with a non-corrosive material and then subjecting the outer shell to a rotational casting movement while heat is applied to the outer shell. The outer shell serves as a mold for the inner shell wherein the mold (outer shell) becomes a permanent part of the completed tank.
