Uses and Applications of Nitrogen Gas and Liquid Nitrogen by Industry
Aerospace & Aircraft
Essential to the aerospace & aircraft industry, nitrogen is used in high Reynolds number wind tunnels, heat treating furnaces and autoclaves to help create incredibly strong but lightweight materials. Nitrogen is also used as an assist gas for laser cutting applications.
Assembly plants, tier 1s and tier 2s use nitrogen in combination with other welding gases to weld auto parts, frames, mufflers and other components because of its ability to provide the necessary atmosphere needed to produce adequate welds with any material. It’s also an important safety component in airbags.
Nitrogen is a key cryogenic agent in cooling, chilling and food freezing. Because of its extremely cold temperatures, immersion freezing in liquid nitrogen is the fastest freezing method known for producing Individually Quick Frozen (IQF) foods. Nitrogen also plays a key role in reducing spoilage, discoloration and off–flavors, giving strength to retail packaging.
Nitrogen NF is used as a cryogen to freeze and preserve blood, tissue, and other biological specimens, and to freeze and destroy diseased tissue in cryosurgery and dermatology. It is also used to power medical devices.
Gaseous nitrogen is commonly used for purging, pressure transferring, mixing and blanketing — protecting a process from moisture intrusion, oxidation, degradation and contamination. Cryogenic liquid nitrogen is used to control the temperature in reactor cooling applications and to preserve biological samples.
In stainless steel tube welding, nitrogen is used as a purge gas. It is also used as an assist gas for laser cutting, and enhances plasma cutting.
