What Is Helium Leak Detection | HVS

Pressure systems can be charged with helium or a mixture of helium and nitrogen. The leak testing is performed by using a Sniffer probe. Helium Leak Detection Applications. Quality control of production parts and assemblies using helium leak detectors can help assure the integrity of your production process. Typical examples include ...

Helium - Wikipedia

Helium (from Greek: ἥλιος, romanized: Helios, lit. 'Sun') is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements.Helium is the second lightest and second most abundant element in the observable ...

Hydrogen leak testing - Wikipedia

Helium leak test. The helium leak test uses helium (the lightest inert gas) as a tracer gas and detects it in concentrations as small as one part in 10 million. The helium is selected primarily because it penetrates small leaks readily, is inert and will not react with the test piece while having a naturally low quantity in air making detection ...

Helium Gas Supplier | Commercial, Industrial Helium Tanks ...

Helium Specifications. Helium is a chemically inert, colorless, odorless gas. Used in many applications where the elimination of air or oxygen is required. Also used for leak checking, inerting, blanketing and industrial applications. Helium is supplied in various cylinder sizes and in bulk form.

Leak Detection | Leak Testing Services | Air Leak Testing

Helium Spray Leak Detection: Is a two-phase gas leak testing process where parts are first placed in a vacuum sealed vessel to perform initial leak detection. If it passes the first phase, helium is then applied to the part to sense whether there are any gas leaks.

How Is Helium Mined? | Sciencing

Jul 21, 2017· It is at this point that the nitrogen gas is removed from the natural gas. Nitrogen becomes a liquid around -70 degrees Celsius. The helium gas is removed from the nitrogen. Helium liquefies at -250 degrees Celsius. Liquid helium is 99.9 percent pure helium. It is cheaper to transport helium as a liquid, so it may be used for various applications.

Helium (He) - Air Products & Chemicals

Helium is found in minute proportions in the atmosphere, less than 0.001% in air. It can also be found in a certain number of natural gas fields, where it results from the natural radioactive decay of heavy elements in the earth’s crust, in particular, uranium and thorium.
