Our expert team can tell you more about the benefits of pipe and tank inerting with nitrogen vs helium.
In-depth Experience in the Design and Safe Operation of Inerting Systems
Complementing nitrogen as a firm favorite for many inerting applications, we also offer helium to counter the risk of residual nitrogen liquefying when supercold liquid hydrogen (LH22) is loaded.
Purging Gases for Different Fuels
Purging with inert gases like nitrogen (N2) and helium (He) is a critical safety procedure at several steps in spacecraft engine testing and launch operations. Lines and tanks are purged with these gases to displace oxygen or moisture, sweep residual fuel or oxidizer vapors out of lines before and after propellant loading, and maintain an inert atmosphere in tanks and fuel lines.
Although nitrogen is a firm favorite for many general-purpose inerting tasks, helium has the added bonus of remaining gaseous under extreme cryogenic conditions. This makes helium a safer option when purging cryogenic lines where very low temperatures could liquefy residual nitrogen as supercold liquid hydrogen is fed into the system.
As one of the largest industrial gas suppliers in the world with in-depth experience designing and operating inerting systems, we support all inerting gas needs for spacecraft engine testing and launch.
