Helium tank description

Yuantong gas has a history of nearly 23 years in Helium which is established on year 1995. Helium is the lightest element after hydrogen, and represents in nature in limited quantities (only 5 ppm of the atmosphere). It is a nonflammable and nontoxic gas. Helium is inert to chemical reactions and radiations. Out of all inert gases, helium has the highest thermal conductivity. The gas is only slightly soluble in water. Liquid helium is the coldest known substance with boiling point of -269 degree C.

Applications

1)Used for welding and as a lifting gas in balloons.

2)Used as a coolant in nuclear reactors and for growing germanium and silicon crystals for transistors, as well as the production of some metals such as titanium and zirconium.

3)Used for filling cold-water fluorescent lamps as well as laser and fiber optic production.

4)Liquid helium is used for cooling superconductive megnets.
