Overview
One of Nitrogen’s most useful properties is its chemical inertness to nearly all substances at ambient and moderate temperatures.
Grade: Industrial 99.9% (Min), Technical 99.95% (Min) and High Purity 99.999%
Unit Of Delivery: Cylinder or Bulk Liquid
Both oxygen and nitrogen are noncombustible; however, oxygen can accelerate the burning of a fire.
Nitrogen is an inert gas that doesn’t ignite or support combustion under normal conditions.
Processes that use Nitrogen
a) Food packaging
In mixture with carbon dioxide and oxygen in modified atmosphere packaging (MAP); pure to reduce oxygen concentration in respiring food products packaging.
b) Heat treatment
As a protective furnace atmosphere for heat treatment of the most reactive metals.
c) Inerting, blanketing or padding
Pure or in mixtures, as a protective atmosphere against oxidation or combustion by atmospheric air and contamination by moisture.
d) Purging
To displace or dilute unwanted gas or vapour, to reduce oxygen concentration or remove air, flammable or toxic vapour.
e) Flushing
To flush unwanted gases from solutions, due to its only slight solubility in a wide range of liquids.
Safety Information
Nitrogen is not toxic and non-reactive except at high temperatures. If insufficient oxygen is present, high nitrogen concentrations cause asphyxiation and death.
There are no physiological warning signs to nitrogen enrichment. Nitrogen does not support combustion. Liquid nitrogen has the capacity to inflict dangerous frost bites.
