GOST (State standard) 6331-78
О2
Use:
Liquid oxygen is produced from atmospheric air through low temperature
rectification
After gasification the material is used for flame treatment of metals and
for other technical purposes.
Characteristics:
The material is not toxic, not flammable, not explosive, but as it is an
oxidant, it sharply increases the flammability of other materials. Some
materials (wood, paper, asphalt, coal, etc. are able to detonate when
impregnated with liquid oxygen.
Package:
The material is poured into steel cylinders, autorecipients (cylinders of
big volume permanently fixed on a car and a trailer), transporting tanks, and
cryogenic vessels.
Transportation:
The product is transported by all kinds of transport in accordance with the
shipping rules for the corresponding kind of transport and the rules for
safe transportation of dangerous materials by rail.

Oxygen (technical gaseous grade)
GOST (State standard) 5583-78
О2
Use:
The material is used for flame treatment of metals and for other technical
purposes.
Technical gaseous oxygen is produced out of atmospheric air through
low-temperature rectification or water electrolysis.
Characteristics:
The material is not toxic, not flammable, not explosive, but as it is an
oxidant, it sharply increases the flammability of other materials.
Package:
The material is poured into steel cylinders of small and medium volume,
autorecipients (cylinders of big volume permanently fixed on a car and a
trailer).
Transportation:
The product is shipped by all kinds of transport in accordance with the
shipping rules for the corresponding kind of transport, the rules for
construction and safe exploitation of vessels under pressure, and the rules for
safe transportation of dangerous materials by rail.
Oxygen gas is also shipped by road in gasification installation, that
provide liquid oxygen gasification on site for the
customers.
The product is also shipped through pipeline.
Guaranteed shelf life:
1,5 year.
