Why Nitrogen Gas (N2) Use in the Aerospace Industry?
Now a days Many manufacturers use Nitrogen to provide an inert atmosphere for pressurising their large autoclaves. These autoclaves operate like huge pressure cookers, heating and curing the various composite parts fabricated by production personnel. These parts are cured in the autoclave under a combination of heat, vacuum and pressure to ensure the layers of composite material successfully bond together to provide the necessary strength to form strong, and lightweight parts.
Specially in the aerospace industry, nitrogen gas can be used to pressurise certain components of autoclaves. Because nitrogen is an inert gas which prevents the possibility of combustion, it is an ideal choice for systems that operate under high temperatures or high pressure.
Autoclaves apply heat and pressure to the workload placed inside of them. However, for workloads that require a dry atmosphere, gas is the optimal choice. Furthermore, applying gas to the pressurisation of the autoclave ensures greater control and regulation of the heating atmosphere for aerospace industry.
With gas pressurisation in autoclaves, nitrogen provides a more versatile operation by eliminating the presence of air, moisture and other contaminants. Because nitrogen is non-combustible, it provides a safe alternative to compressed air, especially in aerospace industry.
Nitrogen can also be used in ejector pumps when processing aerospace parts in autoclaves. Nitrogen can be introduced to remove nearly all of the air in a safe and effective manner. Because safety is a great concern during the manufacturing and processing of autoclave curing, nitrogen is a popular choice due to its inert properties.
Nitrogen can also be a cost-effective solution for large and expensive workloads. Because nitrogen is readily available, even possible to generate from the surrounding air we breathe, it’s an accessible gas to use for large-scale projects.
