Common industrial gases 

Nitrogen (N2)

Nitrogen is used primarily for blanketing volatile chemicals in the industrial market. Most contractors use nitrogen to purge lines when on the job. Nitrogen gas tanks are measured in cubic feet. This means a 20 tank holds 20 cubic feet of Nitrogen. 

Common sizes: 

  • Nitrogen 20 and 40 for typical jobs 
  • Nitrogen 60 and 80 for large or unique jobs

Carbon Dioxide (CO2)

For construction sites, solid CO2 or dry ice is primarily used for sandblasting to remove old paint. Unlike other welding gases, C02 is measured in pounds rather than cubic feet because it’s stored in liquid form. 

Common sizes: 

  • Carbon Dioxide 20
  • Carbon Dioxide 50
  • Carbon Dioxide 450 Micro-Bulk
