Nitrogen (N2)


  • Inactive gas, does not react to any element
  • No color, odor and taste
  • Non-flammable


- As an inert gas in electrical systems
- As blanketing agent in the manufacture of electronic products
- In the chemical industry and food packaging industry
- As an inert atmosphere, and in the filling of some incandescent lamps
- Used in agitation of color film solution in photographic processing
- Blanketing of oxygen-sensitive liquids and of volatile liquid chemicals
- The production of semiconductor electronic components as a blanketing atmosphere
- Blowing of foam type plastics
- In food processing industry for food freezing and as a refrigerant in the processing and refrigerated transport of frozen foods
- Inhibition of aerobic bacteria growth (waste water treatment)
- Magnesium reduction of aluminum scrap
- Propulsion of liquids through pipelines such steam, crude oil, etc.
- Pressuring aircraft tires and emergency bottles to operate landing gear
- Purging in the blazing of copper tubing for air conditioning and refrigerant system
- Purging and filling of electronic devices and voltage compression cables
- Purging and testing of pipelines and related instruments
- Treatment of alkyd resins in the paint industry
- As a gaseous blanket that excludes oxygen and moisture
- In manufacture of ammonia
- In steel industry for blanketing and bright-annealing
- Used in low temperature metal treatment and  shrink-fitting of parts
- deflashing of molded plastic and rubber parts
- in cryobiology for storage of biological materials such as whole blood and bull semen
- as refrigerant in cryosurgical procedures


        Commercially produced at air separation plants by liquefaction of atmospheric air and removal of the nitrogen from it by fractionation.


                          Industrial Grade         High Purity
Nitrogen          99.5% max.                99.99%
Oxygen            Less than 0.2%          Less than 10 ppm
Moisture          Max 45 ppm                 Max 45 ppm

Nitrogen is non-corrosive and so any common metal is acceptable provided equipment is designed to withstand process pressure.


- compressed gas is commonly packed & shipped as a high  seamless, steel cylinders constructed to ICC specifications 3A or 3AA w/ nominal capacities such as 80,122,150,300 cu. ft. of gaseous hydrogen.

- Equipped with safety relief valve consisting of a frangible disc designed to burst under excessive pressure

Containers Sizes and Color Coding:

Type             Content                                Color-Body    Color-Collar
Bantam       (34 L)  4.27 m3 / 4.97 kg              Gray    Black & Silver

Note:  At normal temperature, cylinder pressure ranges from 1800 psig to 2000 psig.


- Use only in a well ventilated area.  Ventilate to prevent the accumulation of high concentrations of Nitrogen and ensure that the oxygen content in the air is greater than 18%.
- Only experienced and properly instructed people should use this gas.
- Nitrogen gas and vapor can cause Oxygen deficient atmosphere leading to asphyxia.
- Always use a regulator to connect to system
- Open cylinder valve slowly, Close cylinder valve when not in use
- Wear leather gloves, full-face safety mask and safety shoes when handling vessels.
- Keep self-contained full face positive pressure breathing apparatus nearby
- Cylinder should be secured from falling over
