Helium 4.6
Helium is inert and lighter than air. This industrial grade is available in a range of volumes either as a compressed gas or a cryogenic liquid
He
Helium 4.6 is used extensively as a shielding gas, resonator gas and for lifting blimps or aerostats. In cryogenic liquid format, liquid helium is often abbreviated to 'LHE'.
Uses
- Used as a resonator gas in laser cutting
- In the welding industry as an inert shielding gas for arc welding
- Alongside helium leak detectors for checking leak tightness in pipelines
- For lifting airships and blimps
