Cylinder-gases  [ Return towards  Gases  ]

Gas cylinders are defined by four main characteristics :

Type of gas :
Oxygen, nitrogen, argon, acetylene, carbon dioxide, hydrogen, helium, rare gases, special gases, nitrous oxide, chemical gases and liquids, medical gases.

State of gas :
compressed gas, refrigerated liquid (CO2, nitrous oxide), dissolved gas (acetylene) or cryogenic liquids.

Purity of gas :
going up to 99.99999 %.

Type of cylinder :
size (volume) and pressure, which differs from one country to another ; small cylinders have been the focus of special development.

AIR LIQUIDE has for many years been putting forward innovative solutions in the gas cylinder field in order to improve its safety, economy and ease of use.



Cylinders can be supplied individually or linked together in groups of 9 or 18 interconnected cylinders, which then empty as if they were a single container.

Materials used in the construction of cylinders are aluminium, steel, light alloys, composite materials, as well as special porous substances filling the interior of acetylene cylinders.

AIR LIQUIDE carries in-house treatments and special packaging procedures to guarantee conformity with specifications. We also undertake regulatory checks and the re-testing of cylinders
