Helium (He) is colourless, odourless, tasteless, non-reacting and especially light-weight inert gas. Helium evaporation and boiling point is the lowest of all elements, therefore, liquid helium is an ideal cooling substance where especially low temperature is necessary.
This gas is usually known as the filler of party balloons that are rising to the sky, however, helium is also important in metal processing, chemistry and pharmacy fields. It is used in under-water diving equipment gas mixtures.
The major part of helium molecules are present in the atmosphere, however, its concentration is only about 5 parts per million. For this reason, obtaining of helium molecules directly from the air is simply impractical, and, for commercial use, helium is extracted from natural gas deposits, where its concentration is much higher. Unfortunately, the resources of helium, same as other non-renewable natural resources, are decreasing.
Helium is filled in brown coloured cylinders.
We offer to purchase helium gas in:
- 5 l cylinders (0,91 m³, 200 bar);
- 10 l cylinders (1,8 m3, 200 bar);
- 20 l cylinders (3,7 m3, 200 bar);
- 50 l cylinders (9,1 m3, 200 bar).
Fields of industry:
Welding.
Shielding gas for TIG and MIG welding, especially for aluminum, copper, and stainless steel. Improves penetration, arc stability, and weld quality.
Laboratories and analysis.
Inert carrier gas for chromatography and analytical instruments.
Diving.
Used in breathing mixtures with oxygen (e.g., heliox or trimix) to reduce nitrogen narcosis and oxygen toxicity during deep dives.
Cryogenics.
Cooling medium for ultra-low-temperature applications.
Balloons.
Non-flammable, lighter-than-air gas used for inflating balloons and decorations.
Medical use.
Used in breathing mixtures for patients with respiratory disorders.
Safety
If helium pushes the oxygen necessary for breathing out of the air, it causes asphyxia (suffocation). Liquid helium can cause cryogenic frostbites. In order to avoid health risks, it is recommended to download the material safety data sheet and observe provided instructions.
