air gas helium
Helium gas (He) is a colorless, odorless, tasteless, non-toxic,inert,monatomicgasthat heads thenoble gasgroup in theperiodic table. Itsboilingandmeltingpoints are the lowest among the elements and it exists only as a
gas except in extreme conditions.

Industrial Helium Gas
High Purity Helium Gas
Exceed High Purity Helium Gas
1). Compared with Hydrogen, it has the advantage of being
non-flammable (in addition to being fire retardant), and it’s
lighter than air, airships and balloons are inflated with helium
2). It is used as a shielding gas in arc welding processes on
materials that at welding temperatures are contaminated and
weakened by air or nitrogen. Helium is used instead of cheaperargonespecially for welding materials that have higher heat
conductivity, like aluminium or copper.
3). It is used as a tracer gas to detect leaks in high-vacuum
equipment (such as cryogenic tanks) and high-pressure containers.
4). For its low solubility in nervous tissue, helium mixtures such
as trimix,helioxand heliair are used for deep diving to reduce the effects of
5). Helium is a commonly used carrier gas forgas chromatography.
6). The use of helium reduces the distorting effects of temperature
variations in the space between lenses in some telescopes, due to
its extremely low index of refraction.This method is especially used in solar telescopes where a vacuum
tight telescope tube would be too heavy.
5. Notice for Helium Gas
-Helium gas is high pressure gas with colorless, odorless,
tasteless, non-toxic, non-flammable stored in gas cylinder.
Normally, its pressure is 15Mpa(150Bar), and should be operation
after reduced the pressure with pressure reducer. Meanwhile, people
should inspect the gas pipeline and make sure the pipeline without
- The cylinder with packed helium gas has life period marked on
cylinder, if over life period, it must be sent to related
department to inspect, and then keep on storing.
- When close the end for helium gas packed with cylinder, there
should be at least 0.25Mpa pressure, then close valve to make sure
the quality and safe.
&The difference of Helium gas and Hydrogen gas to fill balloon
Hydrogen is active gas, and easy to react with other gas. If this,
then cause explosion. But helium gas is a rare and inert gas and
not easy to react with other gas, then very safe, which has been
widely use all over the world.
