Nitrogen (Oxygen-Free) - 30 Litre
Our Nitrogen is filled to the highest quality, meeting or exceeding the latest ISO standards.
Advantages
Has a purity level of 99.999%.
Inert to nearly all substances at ambient temperatures and moderate conditions.
Nitrogen keeps laser-cut faces oxide-free due to the chemical inertness to react with the atmosphere.
At higher temperatures, nitrogen can react to form metal nitrides.
Nitrogen gas is only slightly soluble in a wide range of liquids and is therefore used to flush unwanted gases from solutions.
Reduces internal degradation of the rubber in tyres due to oxidisation.
Applications
Used for blanketing and purging applications to displace or dilute all unwanted gas or vapour.
Widely used for reasons of safety and the prevention of product degradation in the chemicals and petroleum industry:
Inerting reactors and storage tanks
Purging vessels and pipelines
Sparging
Pressure-transfer of liquids
Shielding or assist gas for plasma-cutting aluminium and stainless steel, and as an assist gas for laser-cutting stainless steel TIG-welding of tough-pitch copper.
Heat-treatment processes to protect some of the most reactive metals.
In electrochemical analysis, can be bubbled through to displace any oxygen.
Pressure-transfer, where the movement of liquids or slurries from one piece of process plant to another is effected using gas pressure.
Tyre inflation: helps to extend tyre life and prevent tyre bursts.
Pressurising accumulators for batch-testing applications.
Also used in the beverage drink dispence industry.
