Nitrogen gas is widely used in the food industry, as well as in semiconductors and petrochemicals, for purposes such as purging in piping and preventing oxidation and discoloration for quality preservation.
Nitrogen gas has characteristics such as being non-flammable, non-explosive, and scientifically stable, making it widely used in various industries including food, semiconductors, petrochemicals, and research institutions for applications like purging in piping and preventing oxidation and discoloration for quality preservation. *Example of usage* 【Prevention of oxidation in food, etc.】 Maintaining the flavor of tea and bonito flakes, preventing oxidation of fats and oils, and preventing the hatching of eggs. 【Nitrogen blow during air conditioning piping】 During soldering work, passing nitrogen through the piping prevents the formation of oxidation films (soot) inside. 【As shielding gas for laser processing machines】 Using nitrogen gas, which is one of the inert gases, suppresses oxidation on the processing surface. Since the cutting surface is clean, there is no need to remove the oxidation film generated during laser cutting with oxygen using a grinder before welding, thus increasing productivity.

Applications/Examples of results
※Example of usage 【Prevention of food oxidation, etc.】 Preservation of flavors in tea, bonito flakes, prevention of fat oxidation, and prevention of egg hatching. 【Nitrogen blow during air conditioning piping】 By passing nitrogen through the piping during brazing work, the formation of oxidation films (soot) is prevented. 【As a shielding gas for laser processing machines】 Using nitrogen gas, which is one of the inert gases, suppresses oxidation on the processed surface. Since the cutting surface is clean, there is no need to remove the oxidation film generated during laser cutting with oxygen using a grinder before welding, which increases productivity.
