China EN 1964 Cylinder Suppliers

China EN 1964 Cylinder SuppliersThe main gases used for cutting and welding industrial applications are oxygen, acetylene, argon, nitrogen and carbon dioxide. Carbon monoxide, helium and hydrogen are also used in some special industrial gas mixtures. The source of most of these gases is bulk liquefied gas from air separation units or bulk liquefied carbon dioxide from local sources. Acetylene is produced in specialized cylinder filling facilities by the reaction between water and calcium carbide.

Specialty gases mixtures differ from medical or industrial gas mixtures because they are often sold with a certificate of analysis which states the precise composition of the gas. For this reason, the type of instrumentation used in specialty gases production is generally quite precise. Since there is a broad range of components that may be filled as calibration gases the amount and type of analytical equipment is also highly diverse. The number of gas analyzers required will depend on the complexity of the specialty gases cylinder filling operation at that site.

The two main medical gases are oxygen and nitrous oxide. Oxygen is used for various therapies related to respiratory ailments and nitrous oxide is used for pain relief. They are either supplied separately as pure gases or as a gas mixture, typically 50% nitrous oxide in oxygen. The mixture is created by blending together the pure gases in gas mixing equipment. As with all gas mixing operations, the composition of the gas mixture must be analysed to ensure that it meets the 50 / 50 specification within the acceptable tolerances and the use on an online direct read analyzer such as the Magnos28 for oxygen measurement can support operational excellence.
