Abstract
A steel or concrete liquid tank body 1 has an adhesively secured internal cushioning layer of rubber sheets 2 underlying an adhesively secured lining of corrosion resistant synthetic resin sheets 4. The angular tank body corners are provided with triangular rubber strips 3 to contour the lining sheets and avoid stress concentrations. The overlapping glued and welded joints a between adjacent resin sheets 4 are staggered or offset with respect to the mitered joints b between adjacent rubber sheets, and the corners of the interior of the joints a are spaced from the tank.
