MAIN PROPERTIES AND field of application  

Gaseous nitrogen is an odourless and colourless inert gas, with the density equal to 1,25046 kg/m3 under 00 C and pressure of 760 mm Hg. Is used for creation of the inert atmosphere during production, storage and transportation of easily oxidized products; in the high-temperature processing of the metals not interacting with nitrogen; for preservation of the closed metal tanks and pipelines, and other purposes.
