Carbon dioxide in gaseous and liquid cylinders
Gaseous and liquid carbon dioxide in cylinders is used to create a protective atmosphere during welding, as well as in the production of carbonated beverages.
It is also widely used for the storage of food products and has twice the cooling capacity.
(It is produced as low-temperature liquid, high-pressure liquid, and gaseous CO₂.)
Chemical formula: CO₂
GOST: 8050–85
HS Code: 2811210000
Annual capacity: 10,000 tons
Carbon dioxide is used for various purposes:
• As a protective medium in wire welding
• As an energy source for engines in aeromodelling
• As a leavening agent
• For cooling, freezing, and storing food products
• Widely used in the production of fire extinguishers
• Used as a preservative and labeled on packaging under the code E290
• Used for drying casting molds
Safety requirements:
Gaseous carbon dioxide is an inert gas, colorless and odorless. It is 1.5 times heavier than air.
Liquid carbon dioxide is a colorless, odorless liquid.
Carbon dioxide is non-toxic and non-explosive.
According to its impact on the human body, it belongs to hazard class 4.
