What is industrial grade helium?
A “Grade-A” industrial helium, 99.997% helium is mostly used in cryogenic applications and for pressurizing and purging, but is also used as a control atmosphere in manufacturing, as a cover gas during welding, in breathing mixtures for divers, and leak detection.
Is there different quality of helium?
Depending on the application, the required quality and purity of helium varies. For some scientific applications the required helium purity can be 99.9999% and nearly reach 100% purity for liquid application (at -269°C) – balloon gas is far short of this.
What are the two types of helium?
A liquid mixture of the two isotopes helium-3 and helium-4 separates at temperatures below about 0.8 K (−272.4 °C, or −458.2 °F) into two layers. One layer is practically pure helium-3; the other is mostly helium-4 but retains about 6 percent helium-3 even at the lowest temperatures achieved.
What is industrial helium used for?
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 works as a pressurizing agent for ground and flight fluid systems. It is also a source of lift in weather and other surveillance balloons.
What is medical grade helium?
Medical Helium USP A colorless, odorless, nonflammable gas is only one-seventh as heavy as air. Helium is inert chemically and pharmacologically and can act as a simple asphyxiant by displacing air.
What is high purity helium?
High purity: 99.995% This grade of helium is considered to be a more industrial option for the specialty gas market. This means that it has a wide range of uses across a number of applications but those relating to refrigeration and cooling are some of the most common.
Is helium King pure helium?
Disposable Helium Canister – with enough Helium Has to fill Filled in The UK with High grade Helium (over 98% Pure) The UK’s largest Manufacturer of Disposable Helium Cylinder Helium King Branded Cylinder The pack does not contain any heli-valves.
What are 5 things helium is used for?
Helium is used for medicine, scientific research, arc welding, refrigeration, gas for aircraft, coolant for nuclear reactors, cryogenic research and detecting gas leaks. It is used for its cooling properties because of its boiling point being close to absolute zero.
How is industrial helium made?
Helium is generated underground by the radioactive decay of heavy elements such as uranium and thorium. Helium can also be produced by liquefying air and separating the component gases. The production costs for this method are high, and the amount of helium contained in air is very low.
Is He a compound or element?
Helium
Helium is a chemical element with symbol He and atomic number 2. Classified as a noble gas, Helium is a gas at room temperature.
What industries use helium?
Helium gas is used in medicine, scientific research, for blimp inflation, party balloons as well as having welding applications.
What does the US military use helium for?
Military and defense The U.S. military’s submarine detectors use liquid helium to clean up noisy signals, and the U.S. Air Force uses helium in experiments on superconductors as a power source, according to the National Research Council.
