The gas cylinders are marked on the cylinder shoulder with a surrounding colour stripe in chestnut brown RAL colour 3009 as well as the Linde product and hazard designation. Acetylene is dissolved in acetone and is available in gas cylinders with different filling quantities. Acetylene is a universal fuel gas and is ideally suited for many oxyfuel processes. Colourless and odourless in its pure state, acetylene is an excellent universal fuel gas for a wide range of industrial applications. The hottest and most efficient of all fuel gases, it reaches temperatures of up to 3000 degrees Celsius when mixed with oxygen. Acetylene is used for flame cutting, gas welding, flame brazing, flame spraying, gouging, flame blasting, flame straightening, heating and preheating. Acetylene is highly flammable and can form explosive mixtures with air.
The gas cylinder sizes are 10, 20 and 50 litres. The gas cylinders are marked on the cylinder shoulder with a continuous colour strip in chestnut brown RAL colour 3009 and the Linde product and hazard designation.
Argon belongs to the category of noble gases, is colourless and extremely inert. There are different purity classes for argon. Argon 4.6 is particularly suitable as a welding gas for thinner materials such as aluminium and non-ferrous metals. Argon 4.8 is used for TIG shielding gas welding with materials such as titanium or stainless steel. Argon 5.0 is used as a professional gas for arc welding, plasma welding and plasma cutting. Argon is used as shielding gas for arc welding of easily oxidizable metals such as aluminium or magnesium.
The gas cylinder sizes are 10, 20 and 50 litres. The gas cylinders are marked on the cylinder shoulder colour with a circumferential colour strip in dark green RAL colour 6001 as well as the Linde product and hazard designation.
Welding argon is argon of type 4.6 or 4.8. See description "Argon".
This universal process and shielding gas is suitable for MAG welding of unalloyed and low-alloyed steels regardless of the welding positions. Due to its relatively high content of 18% helium, 2% carbon dioxide (CO2), 3.1% oxygen and 82% argon, CORGON 18 is particularly suitable for all types of arc welding. Characteristic features are a low-spatter spray arc, low weld projection and good burn-in conditions.
The gas cylinders are marked on the flange shoulder with an all-round colour strip in bright green RAL 6018 and the Linde product and hazard designation.
In use In oxyfuel technology as oxygen 3.5 and liquid oxygen 2.5 (highly compressed) for welding, cutting and related processes as well as process gas for plasma cutting. The oxygen stabilizes the arc during welding. As oxygen is an active gas, its function in gas-shielded welding is to cause oxygenation. This stabilises the arc during welding. In so-called MAG welding, the material used is transferred fluidly to the area to be welded.
Gas cylinder sizes 10, 20, 50 litres The gas cylinders are marked on the flange shoulder with a circumferential colour strip in white RAL colour 9010 and the Linde product and hazard designation.
This colourless, odourless and non-flammable gas is a chemical compound of carbon and oxygen. In metal processing, it is used as a protective gas in welding technology, foundry technology, plasma spraying and in smelting metallurgy. It can be used in pure form or as an additive to argon or helium. Other applications are, for example, as a medium for dry ice and in water treatment for the neutralization of alkaline waste water. Carbon dioxide is also used in other branches of industry, e.g. in blowing technology, fire extinguishing technology, high-pressure extruders, etc.
The gas cylinders are marked on the flange shoulder with a circumferential colour stripe in grey RAL colour 7037 and the Linde product and hazard designation.
The gas carbon dioxide CO2 is often colloquially referred to as carbonic acid.
It is mostly used in the gastronomy sector for the effervescence of liquids.
Propane gas has a natural origin and is released as a marginal product during oil or gas production. For later use in gas cylinders, it is industrially processed and liquefied under pressure. Propane is widely used as a fuel gas for heating, cooking, warming and flame cutting. Propane gas is also widely used as a propellant gas for driving forklifts and other engines. Propane is colourless and odourless - it is also heavier than air and therefore settles on the ground.
The gas cylinders are marked on the flange shoulder with a circumferential colour stripe in red RAL colour 3000 as well as the Linde product and hazard designation.
As a leading manufacturer and supplier of technical gases, Linde AG is a global byword for quality and reliability.
The Linde Group has its founding roots with entrepreneur and inventor Carl von Linde in 1873 with the development of a refrigeration machine. At the beginning of the 20th century, the invention of gas production, based on the division of air into its constituent parts, laid a foundation for subsequent success
Today, the Linde Group is a global leader in industrial gases and engineering. This makes the successful global group one of the most important suppliers of technical and medical gases.
The German headquarters of Linde Aktiengesellschaft is located in: Dr.-Carl-von-Linde-Strasse 6-14 D- 82049 Pullach
The availability of technical and medical gases must be guaranteed day and night. In almost all industries, technical gases are the basis for smooth manufacturing and production. As an example, here are just a few industries such as the chemical industry, the food industry, pharmaceutical and medical technology, the construction industry, plant engineering, mechanical engineering, and vehicle construction, etc. The smooth supply of technical gases is provided by the Linde Gas production and distribution sites. Nenok GmbH in Cologne-Kalk has also been part of this successful distribution system since 2019. Throughout Germany, far more than 100,000 customers are supplied with Linde gases through 9 distribution centers and more than 1000 delivery points.
Because of the high responsibility for the environment, employees and customers, the supply security with modern production facilities and continuous quality control is in the foreground. According to the applications of the customers adapted delivery forms are used. This starts with 1 liter cylinders and ends with large gas tanks with up to 75,000 liter volumes.
