Liquid helium is odorless, colorless, non-corrosive, extremely cold and non-flammable. In ordinary conditions, helium does not react with other elements or compounds. As helium has non-corrosive properties, special materials of construction are not required. However, materials that are used must fit with the low temperature of liquid helium. Pipes and vessels must be chosen and designed to withstand the temperature and pressure involved in transportation and use.
How is liquid helium manufactured?
The maximum amount of helium is retrieved from natural gas through a cryogenic separation process. Usually, the volume of helium is less than 1% in natural gas. Helium is acquired, refined and liquefied. Then, the liquid helium is typically shipped from the production sources to storage and transfer facilities. Tankers, carrying liquid helium contain an annular space that is insulated with vacuum, multilayer insulation, and nitrogen shielding. This design of tanker reduces the heat leakage, and vaporization of liquid helium while being transported.
What are the uses of liquid helium?
The exceedingly low temperature of liquid helium is used to preserve the magnet’s superconducting properties in applications like NMR spectroscopy, MRI, and other physics research. The most important application for gaseous helium is for inert shielding gas in laser welding and metal arc. Helium is used in these purposes to provide a protective atmosphere in the production of reactive metals like zirconium and titanium. The gaseous form of helium is utilized as a coolant in the course of drawing optical fibers, as a leak detection gas in a wide range of industries and as a carrier gas for chromatography. As helium is lighter than air, it is used to inflate balloons and airships.
