Nitrogen (N2) is colourless, odourless, tasteless, non-toxic and chemically inert (i.e. non-reacting at low temperatures) gas.
In many fields of industry, nitrogen is considered useful and is used in reducing combustion processes and creation of protective environment in order to avoid oxidation processes.
Nitrogen is obtained from atmospheric air through deep freezing method. Nitrogen is filled in grey coloured cylinders with black shoulder, cylinder bundles, dewars, euro-cylinders and other cryogenic tanks.
We offer to purchase nitrogen in:
- 5 l cylinders (0,95m3, 200 bar);
- 10 l cylinders (1,91 m3, 200 bar);
- 20 l cylinders (3,9 m3, 200 bar);
- 50 l cylinders (9,5 m3, 200 bar);
- Cylinder bundles 12 x 50 l (114 m3, 200 bar);
- Cylinder bundles 12 x 50 l (158 m3, 300 bar);
- Dewars from 3 kg to … (subject to the volume of dewars);
- Euro-cylinders from 230 l iki 1000 l;
- Liquid nitrogen (in tons).
Fields of industry:
Protective atmosphere – used as an inert gas in TIG, MIG, or plasma welding processes to protect the weld seam from oxidation.
Steel and alloy processing – helps maintain weld structure and reduces porosity formation, especially with stainless steel and duplex steels.
Plasma cutting and welding – used as a primary or auxiliary gas to ensure high cutting quality.
Surface hardening – nitrogen can be used during heat treatment to improve the metal’s surface properties.
Also, suitable for industrial welding operations, equipment manufacturing, structural fabrication, and repair processes where oxidation protection and high weld quality are essential.
Safety:
If nitrogen pushes the oxygen necessary for breathing out of the air, it causes asphyxia (suffocation). Liquid nitrogen can cause cryogenic frostbites. In order to avoid health risks, it is recommended to download the material safety data sheet and observe provided instructions.
