FORMIER® - Nitrogen and Hydrogen mixtures

FORMING® is the group of gas mixtures containing hydrogen and nitrogen in different proportion. Using FORMIER® eliminates the need for post-weld cleaning with low surface oxidation

Following gas mixtures are available: 

  • FORMIER® 5 - 95% of nitrogen and 5% of hydrogen
  • FORMIER® 10 - 90% of nitrogen and 10% of hydrogen
  • FORMIER® 15 - 85% of nitrogen and 15% of hydrogen
  • FORMIER® 20 - 80% of nitrogen and 20% of hydrogen

Supply modes: FORMIER gases from Linde are available in cylinder sizes ------, with pressures ----.
