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




USES:

- 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




PROCESS DESCRIPTION

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



GAS COMPOSITION

                          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



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



CYLINDER INFORMATION:

- 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.



SAFTEY PRECAUTIONS:

- 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
