Gas bags can be manufactured in the shape of cylinders or angular cushions. This depressurized gas storage System is mounted inside buildings and/or steel or concrete tanks.
Their shape is frequently determined by the space available for them. Cylinder-shaped gas bags are used either in a horizontal position in buildings or suspended in steel and concrete tanks. Depressurized gas bags are mostly filled and emptied via outlets in the stable top or bottom surfaces. The filling level is measured using a rope length system. In order to achieve good measurement accuracy, it is possible to load down the horizontal gas bag with weights. This ensures a regular movement of the membrane. Gas bags must be surrounded to withstand external loads.
The membranes are manufactured from polyester fabric that is PVC-coated on both sides. Different membrane types are used, depending on the prevailing static, legal, and customer requirements.
