Optimizing Your Aerospace Manufacturing Operations (1.9 MB)
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.
Used as fuel, industrial hydrogen fuels rockets and powers life-support systems and computers in space environments. It is also used for metal sintering and annealing.
Our liquid oxygen has been used in many bipropellant vehicles since the 1940's.
Argon is a versatile industrial gas used in the production of light bulbs and lasers, and in welding applications. As an inert gas, it is also commonly used in vacuum carburizing and other heat treating processes.
Helium is used as a lift gas, in both the liquid and gas form, to purge and pressurize liquid hydrogen fuel systems and detect leaks.
From annealing and brazing to sintering and carburizing, our nitrogen-based heat- treating applications are low in cost, high in productivity, and help you meet the stringent standards of the aerospace & aircraft industry.
Precise, Reproducible, Traceable Atmospheres (2.2MB)
Our proprietary Dilute Oxygen Combustion burners are used to provide even heating in critical preheating processes for the forging of exotic alloys for jet engines and other critical aerospace and aircraft parts.
At Praxair, we design and install customized systems to provide the high pressure, high flow rates required for autoclave inerting.

Welding & Metal Fabrication
We do more than provide industrial gases, applications and products to the aerospace & aircraft industry. We offer high performance surface coatings that increase performance by reducing harmful effects of abrasion, oxidation, corrosion, wear and extreme heat on commercial and military aircraft engines and airframe parts and accessories for fixed-wing aircrafts and helicopters.
We also tailor our supply systems to meet your needs and improve performance. From high volume systems and high pressure pumping technology that deliver reliable supply and reduce loss, to pressure testing and cleaning services that help maintain tank and piping integrity, we help you get the most out of your supply.
At Praxair, we work with you to optimize every step of your manufacturing process. From consultation to implementation and use, we offer a range of industrial services that help you monitor and manage your gas supply so you can improve your product quality.
