Inerting

Expert solutions to help you succeed

Inerting atmospheres in metals and materials processing manufacture refers to non-reactive gases or gas mixtures, that minimize undesirable reactions with oxygen during the process and allow non-oxidative reactions to occur.

Typical inert gases are nitrogen, argon and helium, although for processes involving reactive metals like titanium, aluminum or magnesium, only argon or helium can be used. Inert gases also provide an important safety benefit for flammable atmospheres by purging oxygen from the furnace at the beginning of the process and eliminating opportunities for explosion.

Which nitrogen supply makes sense—on-site generation or liquid delivery?

If your operation uses nitrogen, you may wonder when on-site generation makes sense instead of liquid delivery. Here’s some information to help you understand if on-site nitrogen generation may be the supply mode for you. The appropriateness of on-site gas generation depends on many factors—nitrogen flow and purity are the most important ones. Flows with a steady or sufficient baseline rate can be great fits for on-sites. Periodic or erratic flow patterns can also be appropriate if there is a suitable baseline flow or the volumes, pressure and purity are sufficient to allow gas storage that covers peak flows. Also, the lower the purity requirement, the greater the fit (although high purity is okay at higher volumes). Other factors you should consider include local power cost and the pressure that’s required. There are no firm rules defining when you should switch from delivery to an on-site system. However, with our extensive experience in on-site technologies and gas delivery, we can help you determine your optimal supply mode.
