Materials compatibility

Recommendations : Air Liquide has gathered data on the compatibility of gases with materials to assist you in evaluating which materials to use for a gas system. Although the information has been compiled from what Air Liquide believes are reliable sources (International Standards: Compatibility of cylinder and valve materials with gas content; Part 1- Metallic materials: ISO11114-1 (March 2012), Part 2 - Non-metallic materials: ISO11114-2 (April 2013), it must be used with extreme caution and engineering judgement. No raw data such as these can cover all conditions of concentration, temperature, humidity, impurities and aeration. It is therefore recommended that this table is only used to identify possible materials for applications at high pressure and ambient temperature. Extensive investigation and testing under the specific conditions of use need to be carried out to validate a material selection for a given application.

More information

Xenon was discovered in 1898 by Sir William Ramsay and Moris William Travers. Its name comes from the Greek word "ξένον" (xenon), neutral singular form of "ξένος" (xenos), meaning "foreign", "strange" or "host". Neon, krypton and xenon are known as "rare" gases, since combined they only account for one thousandth of the air which surrounds us. These gases are colorless and tasteless. They are so inert that they do not react and can only be combined with other chemical substances with great difficulty. Their extreme inertness makes them very valuable for certain applications.
