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.
Claims5
In an anticorrosive tank for caustic liquids or the like including a tank body, a cushioning layer comprising adjoining sheets of shock absorptive material adhesively secured to the internal surface of the tank body, and a lining layer comprising adjoining sheets of corrosion resistant synthetic resin material overlying and adhesively secured to the shock absorptive sheets, said corrosion resistant synthetic material forming a liquid-containing interior tank surface the improvements characterized by:
- (a) the joints between adjacent resin sheets being offset from the joints between adjacent shock absorptive sheets, and
- (b) the resin sheet joints being spaced from the corners of the liquid-contacting interior surface of the tank, and
- (c) the adjoining resin sheets are generally rectangular and have long and short sides, and the horizontal joint lines between the short sides of adjoining resin sheets are staggered with respect to the horizontal joint lines between the short sides of resin sheets adjacent each other along the long sides.
