Ultra-large soft liquid/gas storage tank

Soft liquid storage tank is actually a collapsible soft container which is consisted of high strength, stabproof, tear resistant and low temperature resistant polyurethane (TPU) coated cloth. It is synthesized by high frequency welding or thermal synthesis. Compared to steel tank, soft liquid storage tank is light weight, UV-resistant, ageing resistant, oil proof, no corrosion, small volume after cuttle fold, handling and transportation, easy to unfold and roll-up, adaptable, good mechanical performance, well-sealed tank, no damage after multi-folding and other advantages, and its weight is only 10% and 2%-5% same capacity of steel tank. Based on the storage material, it can be called soft oil tank, soft water tank, soft tank and other tanks. And it will not contaminate the storage materials.
