Name: helium gas

Purity: 99.9~99.999%

Property: colourless, odourless, non-flammable, non-reactive, inert gas

Application: Helium has a multitude of applications, as a “light gas” that can lift balloons and airships, as a detector gas to detect the smallest of leaks in pipelines and tanks, as an important component in shielding gases for welding, as a carrier gas in residue analysis, in the manufacture of optical glass fibers or as a coolant in space technology and medicine.

Package:  200bar or 150bar cylinder pakage or packed according to demand
