Individual gases typically are available as industrial grade. Many mixtures of these gases are also available and often standard mixtures are supplied for specific processing results. Industrial, by definition, is acceptable for wide ranging applications - from welding to food packaging. The most common form of delivery is in low or high pressure cylinders.
All gas cylinders supplied by Linde are labeled in accordance with federal regulations, and valved in accordance with the American National Standards Institute Standard B-57.1 and CGA V-1 Publication for Valve Connections.
ODOROX® Odourized Oxygen is the early warning system that works with your nose. ODOROX odourized oxygen has a clearly detectable smell to warn of potential leaks and dangerous accumulations of gas. The beauty of the ODOROX concept lies in its simplicity: if you can smell it, something is wrong. ODOROX odourized oxygen contains small amounts of Dimethyl Sulfide (DMS) which, with its highly distinctive smell, will alert you when the oxygen concentration rises as little as 1% (i.e. from 21% to 22% oxygen in air).
ODOROX odourized oxygen significantly enhances safety and complements existing safe practice in all oxy-fuel applications. It is intended for use in any industrial application where oxy-fuel would normally be used and is available in cylinders and for odourizing supply systems. The addition of small amounts of DMS in no way affects the performance, behaviour or shelf life of the oxygen. Instead, it unmistakably warns you if there is an oxygen leak so you can immediately take appropriate action.
Linde supplies Modified Atmosphere Packaging (MAP) gases for use in food preservation and packaging. MAP is a method for extending product shelf life, preserving the high quality of foodstuffs, and improving overall cost-effectiveness. Our MAPAX® family of gas mixtures can do all of this for the food packaging company.
The gases used most often are carbon dioxide (CO2), nitrogen (N2) and oxygen (O2). The gas or gas mixture used depends greatly on the foodstuffs involved along with ambient and packaging parameters. Gases can be supplied either premixed in cylinders under high pressure or as separate gases for subsequent mixing in the packaging machine.
Helium filled balloons add color, enjoyment, amusement and entertainment to parties and other festive events. This gas is available at our retail store outlets along with inflator connections.
Helium/hydrogen mixtures are also supplied for outdoor display and weather balloons.
Gas lasers need laser gases in order to generate the laser beam. The laser gas mixture required to run a CO2 laser contains 60-85% helium, 13-55% nitrogen and 1-9% carbon dioxide. The exact composition varies depending on the type of laser and the manufacturer. Some laser types also require small additions of other gases such as oxygen, hydrogen or xenon. The TEA laser gas mixture, on the other hand, often contains a small percentage of CO. CO is toxic and aggressive, requiring additional safety devices in the gas supply system.
The laser gas needed for an Excimer laser consists of 0.05-0.3% halogen (fluorine or hydrogen chloride), 1-10% rare gas (krypton, xenon or argon) and 90-99% buffer gas (helium or neon). For safety reasons, the halogen is always diluted with helium or neon.
Today, laser manufacturers demand relatively high-purity laser gases. Impurities in the laser gas impede the laser performance by lowering the output power, disturbing the uniformity of the electrical discharge and requiring frequent service and maintenance for the laser optics. The most harmful impurities have been identified as water vapor and hydrocarbons.
Impurities in the laser gas, however, come not only from the gas cylinders themselves but can also be introduced via a poorly designed and set-up gas distribution system. Selection of appropriate components for the gas supply system and expert installation are therefore crucial for reliable and satisfactory laser operations.
The potential of a welding process can only be fully utilized if the shielding gas is properly suited for the job. Our knowledge of how this tool works is our active contribution to obtaining the best overall value for your welding process.
The welding process can be influenced in a number of ways with the aid of shielding gases. It can be optimized for material, thickness, welding position, and many other factors. The gas or gas mixture must be selected according to the required effects on the welding process.
The MISON family of welding shielding gases. The right mixture for each application. MISON is not just one gas, but a range. Each mixture in that range has been developed for a specific type of welding applications or group of applications to bring you the very best. So whatever your base metal, filler metal or method, you can select from the MISON range to optimize the welding result - higher deposition rates, improved weld characteristics and the right weld quality and appearance.
MISON shielding gases contain a small concentration of nitric oxide which reacts with ozone generated around the weld, reducing it at its source. Production usage has realized several other benefits:
Superior arc starts
Increase welding speed
