Additional Pure Gases for Industrial Applications
Contact us to learn more about these pure gases.
Acetylene C2H2
Acetylene is a standard fuel gas used in conjunction with oxygen for welding metals and cutting steel, and for allied oxy-acetylene processes for the heating, forming and treating of metals. Acetylene is available in cylinders.
Air (Industrial Grade)
Industrial grade compressed air is also available from Air Liquide. It is typically used to power pneumatic tools and machines, inflate tires, clean assembly parts and for many other applications. Industrial grade air is available in convenient single cylinders or multi-cylinder packs.
Argon Ar
Argon is an inert gas that is often used in shielded arc processes for welding aluminum, stainless steel, bronze and copper. In these processes, argon is used as a shielding gas, either in pure form or in combination with predetermined percentages of oxygen, carbon dioxide or helium, depending on the metal being welded. The shielding gas provides an inert atmosphere during welding to prevent oxidation or other chemical change of the metals that would be detrimental to the weld. Argon is also used for inerting in other industries such as wine making and food applications, and is available in single cylinders or multicylinder packs.
Carbon Dioxide CO2
In addition to its well-known and extensive use as the carbonating and dispensing medium in the beverage industry, carbon dioxide has numerous other uses in many different industries. For example, in metal fabrication operations, CO2 is widely used as a shielding gas in a semi-automatic welding process. In the food industry, CO2 is employed for processing, packaging, transportation and refrigeration of meat products, frozen foods, dairy products and as an inert atmosphere over perishable products. CO2 is commonly used to neutralize process and waste water streams. CO2 is available in single cylinders or multi-cylinder packs.
Helium (Industrial Grade) He
Helium is used considerably in the welding industry as an inert shielding gas for arc welding. It is used both as a pure gas and in mixtures with argon for TIG or MIG welding. In some applications, helium has the advantage over argon in gas-shielded arc welding because it provides greater arc heat for the same welding currents and arc length. This results in deeper penetration which is preferable for welding heavier materials when greater welding speed is required or when metals of high thermal conductivity are to be welded. Helium is available in single cylinders or multi-cylinder packs.
Hydrogen H2
As a fuel gas with oxygen, hydrogen produces a relatively low flame temperature of 5,125°F (2,830°C) and is most useful for the brazing of aluminum and magnesium, and for lead welding. Because hydrogen can be safely compressed to overcome underwater pressures, oxy-hydrogen cutting torches are sometimes employed by divers on salvage operations. Mixed in small quantities with argon, hydrogen brings significant improvements in weld quality for stainless steels. It is also used in plastic brushing applications and for cooling in turbine power plant generators. Hydrogen is available in single cylinders and multi-cylinder packs.
Nitrogen N2
Nitrogen is used in purging applications for heating, ventilation and plumbing industries. Large volumes of nitrogen are required by oil refineries and petrochemical industries for purging and blanketing operations. Nitrogen is also being used at a sharply increasing rate by the food industry. In its liquid form, it is employed to quick-freeze a wide variety of perishable foods, some of which cannot be successfully frozen by conventional methods. In its gaseous form, nitrogen is used in storage facilities for fresh produce to delay ripening and deterioration. Nitrogen is available in single cylinder and multi-cylinder packs.
Oxygen O2
Oxygen is commonly used in industrial applications in conjunction with acetylene and other fuel gases in processes such as metal cutting, welding, flame hardening, scarfing, cleaning, hard-facing, etc. Oxygen USP is available for customers licensed to dispense medical oxygen. Oxygen is available in single cylinders or multi-cylinder packs.
RESPAL™ Breathing Air
Air Liquide offers breathable air that meets CGA Grade D standards. RESPAL features tighter specifications for oxygen, CO and CO2 than typical Grade D, making it an industry standard for breathable air. It is available in convenient single cylinders for limited applications, as well as in multi-cylinder packs and tube trailers for those applications requiring larger quantities. RESPAL cylinders are equipped with
our exclusive SCANDINA™ cap for added safety and a residual pressure valve to prevent backflow contamination of cylinder contents.
