Helium (HE) is used in various industrial applications as well as in filling balloons, research balloons among others. The gas is used as an inert medium for arc welding. It is most often used for pressurizing liquid-fueled rocket tanks and in wind tunnels. Helium (HE) comes in a hermetically sealed gas chamber. It is easy to release the gas from the chamber in a controlled manner. Due to its purity and effectiveness, we are seeing a huge demand for the helium gas in the marketplace.
