Buy helium or buy liquid helium (HE)
Helium is a highly specialized product. It is a non-flammable inert gas with high thermal conductivity, small molecular weight and size, and the lowest boiling point known. Praxair offers various types of helium and liquid helium (He) with a purity of up to 99.999%. If you don't find what you need, please contact us and Praxair will produce a two-component or multi-component helium mixture according to your specific technical requirements.

Application of helium and liquid helium in various industries
Helium is widely used in aerospace and aircraft manufacturing from manufacturing to flight. Space flight operations use helium to purify the hydrogen system, which is used as a pressurizing agent by ground and flight fluid systems. In addition, helium is used as a source of lift for meteorological and other observation balloons.
Helium is used to test important automotive components such as radiator heat exchangers, air-conditioning components, fuel tanks and torque converters to ensure that they meet quality specifications. In addition, helium can also be used in conjunction with argon, and is increasingly used for airbag inflation.
When diving, the combination of oxygen and helium can effectively eliminate nitrogen anesthesia, reduce deep breathing resistance and shorten the decompression pause time. The helium-oxygen mixture allows divers to stay deeper in the water for longer. The deeper the dive, the higher the helium concentration, allowing the diver to dive deeper and achieve longer welding times.
Helium plays an important role in the manufacture of semiconductors, liquid crystal panels and fiber optic lines, enabling rapid cooling of parts to increase productivity, and control of heat transfer rates to improve production efficiency and reduce defects; in addition, helium can also Acts as a carrier gas during production.
As an ideal cryogenic gas for magnetic resonance and nuclear magnetic resonance superconducting magnets, helium can achieve a cryogenic temperature of -451 degrees Fahrenheit, effectively acquiring high-resolution images of internal organs and tissues.
The inertness of helium under arc temperature conditions makes it an ideal gas for welding highly thermally conductive materials such as aluminum, stainless steel, copper, and magnesium alloys. It can also be used as a quenching gas and a furnace gas during heat treatment to improve the durability and quality of parts.
