Nitrogen (Oxygen-Free) - 20 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.
