Helium is the most frequently occurring element after hydrogen in the Universe. Nevertheless, pure helium is found rather rarely on Earth. Its main deposits are located in the USA, China, Russia and Algeria. Therefore, these countries are leading in the industrial production of this gas.
Helium is obtained artificially by deep cooling (to -190°С) from helium-containing gases. This technology takes advantage of the specific property of helium, its lower compressibility compared to other gases. The main components are condensed, and the remaining concentrate is purified from hydrogen and neon impurities.
- Lighter than air
- Colorless and odorless
- Classified as an inert gas
- Has higher thermal conductivity than other gases (except hydrogen)
- Poorly soluble in water compared to other gases
- Low-risk substance in terms of its effect on the body
- May cause asphyxiation
- Cylinders may explode when heated.
Helium, a high-purity gas, has unique properties that are essential in modern industries. It is known for its complete inertness (protective medium in metal welding, production of ultrapure and semiconductor materials, chromatography), high thermal and electrical conductivity. For this reason, pure helium is often used in various fields: from aviation and nuclear industries to medicine and food production.
For example, helium is used in breathing mixtures (since it is non-toxic), added to diving cylinders and airships. Liquefied helium is used as a cooling agent in scientific research.
Helium is lighter than air, so it is used as a filler for balloons. These are used for decoration and in scientific applications. For example, meteorologists use helium balloons to lift measuring instruments to the required altitude.

Construction 
Metallurgy Helium is transported in steel cylinders and special containers using all types of transport, following safety regulations. Liquid helium cylinders must be stored only in an upright position.
Purchasing pure helium in cylinders, suitable for most technological processes, is not difficult. You can place an order by contacting the specialists at BK Group by phone +7 (495) 118-41-95.
