Technical Oxygen (O2)

 

Characteristics:

 

 

  • Odorless
  • Colorless
  • Tasteless
  • Not very active at ordinary temperature but is active at elevated temperatures.

 
Type: Industrial Grade

 

 



USES:

 

In Metal Processing

-  Production of steel in open-hearth or basic oxygen furnace
-  Flame cutting and welding
- Removal of scale from billets by an oxyacetylene flame
- Jewelry making
- Gold processing
- Brazing



PROCESS DESCRIPTION:

RAW MATERIAL: AIR
- COMPRESSED
- FILTERED AND DRIED
- COOLED TO -250 oF (-160 oC)
- DISTILLED



MATERIAL COMPATIBILITY

- All materials used must be fully degreased and free from oil. Oil and grease can cause ignition.
- Copper, brass and stainless steel are the most commonly used metals.
- Most lubricants are NOT compatible.



CYLINDER INFORMATION

- Seamless, steel cylinders constructed to ICC (Interstate Commerce Commission) specifications 3A or 3AA and having nominal capacities such as 80, 122, 150, 244 and 300 cu ft. of gaseous oxygen
- Equipped with safety release devices designed to release the gas in the event the cylinder is subjected to an abnormally high temperature as in fire.



PRECAUTIONS IN USE:

- Use only equipment which is approved and degreased for oxygen service
- Do not refer to gaseous oxygen as “AIR.” Call it by its proper name, “OXYGEN.”
- Never lubricate oxygen valves, regulators, gages, or fittings with oil or any other combustible substance.
- Vigorously supports combustion of many materials which will not normally burn in air
- Store away from flammable products. 
- Never smoke or carry out work in Oxygen rich atmosphere or clothing saturated with oxygen.
- Never permit oil, grease, or other readily combustible substances to come in contact with oxygen cylinders, valves, regulators, gages and fittings. Oil and oxygen may combine and may explode when ignited.
- No smoking or naked light within the specified area
- Always use a regulator to connect to system
- Open cylinder valve slowly
- Close cylinder valve when not in use
- Do not handle oxygen cylinders or apparatus with oily hands or gloves.
- Never use oxygen as a substitute for compressed air. It is dangerous to use oxygen for pneumatic tools, start Diesel engines, for imposing pressure in oil reservoirs, for painting spraying, for blowing out pipelines, etc.
