Nitrogen

Nitrogen is 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. Common applications include:

• Blanketing and purging applications to displace or dilute all unwanted gas or vapour
• Inerting reactors and storage tanks
• Purging vessels and pipelines
• Tyre inflation: helps to extend tyre life and prevent tyre bursts
• Shielding or assist gas for plasma cutting aluminium and stainless steel, and as an assist gas for laser cutting
• Pressurising accumulators for batch-testing applications
