Helium is a highly specialized product. At Praxair, we deliver gas and liquid helium He in a variety of purities up to Explore the chart below to view the spec sheets and safety data sheets for our pure helium products and a few of our popular welding mixtures. Helium Gas Safety Data Sheet Liquid Helium Safety Data Sheet At Praxair, we develop the right grades for the right applications.
From manufacturing to flight, helium is widely utilized throughout the aerospace and aircraft industry. In space flight operations, helium is used to purge hydrogen systems and to pressurize ground and flight fluid systems. It can also provide lift in weather and other surveillance balloons. Helium is used to test critical automotive parts such as radiator heat exchangers, air conditioning components, fuel tanks and torque converters to ensure they meet quality specifications.
It is also used in combination with argon as a source of inflation in a growing number of airbags. Heat Treating Parts Manufacturing. In combination with oxygen, helium is used in diving to help eliminate nitrogen narcosis, reduce breathing resistance at depth, and shorten decompression stops. Known as heliox, the mixture allows divers to reach greater depths for longer periods of time. The deeper the dive, the higher the concentration of helium, allowing divers to explore more and weld longer.
Helium plays a significant role in the manufacturing of semiconductors, LCD panels, and fiber optic wire. It cools parts and components quickly to enhance throughput, controls the rate of heat transfer to improve productivity and reduce defects, and functions as a carrier gas in the production process. Helium is used to achieve cryogenic temperatures of degrees required for superconducting magnets in MRIs and NMRs, allowing the capture of high-resolution images of internal organs and tissues.
Helium is produced commercially and is commonly used in superconducting magnets in nuclear magnetic resonance NMR systems. At normal atmospheric pressure, liquid helium boils at at temperature of 4.
It is important to have helium transfills scheduled in a timely manner to prevent the magnet from warming up and quenching. Helium's inert properties at arc temperatures make it an ideal gas for welding materials with high heat conductivity such as aluminum, stainless steel, copper and magnesium alloys.
Helium is also used in heat treating processes such as gas quenching and in furnace atmospheres to produce parts with higher tolerance and improved quality. We offer gaseous helium in a large range of high-pressure cylinders, and liquid helium in wide variety of dewars. Specialized packages are also available and designed for specific industries and applications. Our bulk liquid and gas delivery systems allow us to provide a full range of purities to meet your helium supply needs. We offer gaseous helium in tube trailers, in receivers permanently installed onsite, or in ISO framed modules.
We also supply liquid helium in specially designed bulk liquid ISO framed containers with volumes of up to 15, gallons. At Praxair, our scale and reach lets us supply any gas, for any application, almost anywhere in the world — safely, reliably and cost-effectively.
