Bladder tank
A bladder tank is a large, flexible container used to store many types of liquids. When maximum capacity is reached, the bladder tank takes the form of a large pillow, hence it is also called a pillow tank. History The first engineered flexible bladder tank was constructed from rubber in 1926 and manufactured by John Boyd Dunlop in Manchester UK, then later made from modern materials such polymers, and from PVC in Algeria, Africa in the 1950s. It was invented by André Labaronne (patent N°1.460.825, 19 October 1965) and marketed under the brand CITAF (Citernes pour l’agriculture Française). The technology was popularized in the early 21st century, with many wines, for example, shipped by flexitank then bottled nearer a final point-of-sale. Description Flexible bladder tanks are made from numerous materials depending on the chemical compatibility of its content. LLDPE, PVC, TPU and Nitrile rubber panels/sheets are all welded in different ways through; heat, High frequency and vulcanizing consequently. The panels/sheets are joined to form a sleeve which is then closed at each end to form a bladder tank. Materials selected for manufacturing bladder tanks in the first instant is for their Chemical compatibility of its content, secondly UV resistant if
