What is Helium?
Helium (from Greek: ἥλιος, Latin: helios, lit. ‘sun’) is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless substance, Non-toxic, inert, monatomic gas, the first of the noble gases on the periodic table. Its boiling point is the lowest of all the elements. Helium is the second lightest and second most abundant element in the universe (hydrogen is the lightest and most abundant).
It makes up about 24% of the total element’s mass, more than 12 times the mass of all the heavier elements combined. Its abundance is similar to that in both the Sun and in Jupiter. This is due to the very high nuclear binding energy (per nucleon) of helium-4, for the next three elements after helium.
This helium-4 binding energy also explains why it is a product of both nuclear fusion and radioactive decay. Most of the helium in the universe is helium-4, most of which was formed in the Big Bang. Large amounts of new helium are being produced by nuclear fusion of hydrogen in stars.
Helium gas properties
- Helium element symbol: He
- Formula of single substance (molecular): He
- Oxygen’s Atomic Mass: 2
- Molecular Mass of Oxygen: 4
- Helium (He) is an inert, non-toxic, colorless, tasteless gas with a very low density of 0.178g/l and is the most difficult to liquefy gas known.
- Helium (He) can diffuse well through solids, it is much lighter than air and argon and it does not react with most chemical elements, so it is very suitable as a shielding gas in welding technology.
- Helium has the lowest boiling point of all the elements and can only solidify under very high pressure. This element is usually a monatomic gas
Applications of industrial helium gas in industries
Aviation and Airplanes
From manufacturing to flying, helium is widely used in the aerospace and aircraft industries. In spaceflight operations, helium is used to purge hydrogen systems and act as a pressurizing agent for terrestrial and flight fluid systems. It is also a source of lift in weather and other monitoring airships.
Automotive & Transportation Equipment
Helium is used to test critical automotive components such as radiator heat exchangers, air conditioning components, fuel tanks and torque converters to ensure they meet specifications. Quality specifications. It is also used in combination with argon as a cause of inflation in the growing number of airbags.
Dive
When combined with oxygen, helium is used in diving to help eliminate anaesthesia, reduce respiratory resistance at depth, and shorten decompression downtime. Called heliox, this mixture allows divers to reach greater depths for longer periods of time. The deeper the dive, the higher the helium concentration, allowing the divers to explore more and weld longer.
Electronic device
Helium plays an important role in the manufacture of semiconductors, LCD panels and fiber optic cables. It cools parts and components quickly to increase throughput, controls heat transfer rates to improve productivity and minimize defects, and acts as a carrier gas during manufacturing.
Health care
Helium is used to achieve the freezing temperature of -451 degrees required for superconducting magnets in MRI and NMR, allowing for high-resolution images of internal organs and tissues.
Welding & Metal Fabrication
Helium’s inert nature at arc temperatures makes it an ideal gas for welding materials with high thermal conductivity such as aluminum alloys, stainless steel, copper and magnesium. Helium is also used in heat treatment processes such as gas quenching and in furnace environments to produce parts with greater tolerance and improved quality.
Price of industrial Helium
SIG Vietnam supplies industrial helium in gas and liquid form. Helium is delivered in 40L, 50L gas bottles and pallets or loaded into customer bottles at the filling station in the factory.
