Generally, an inflatable ball is related to the size of the cylinder, the pressure and the size of the balloon. Let's take a 12-inch balloon as an example:

For example, 8L and 13MPa helium bottles can be filled with 120 cylinders with a charge of 12 inches, and 40L and 13MPa can be filled with 600 cylinders.

But a 10L cylinder with no pressure can be filled with about 35 disposable cylinders.

Helium balloons generally choose low-purity industrial helium, such as 99.9 helium more, due to the wedding market demand for balloons, so the demand for industrial helium in the future will be rising trend.
