Air Liquide’s over-the-fence high pressure gas quenching supply solution.
The primarily steel metals that make up our trains, planes and cars, must be cut, welded, or formed. Heat treatment is a critical step in this transformation.
Air Liquide’s ALNAT™ metal heat treatment solutions significantly enhance the metallurgical and mechanical properties of material components.
At the other end of the spectrum, Air Liquide’s deep cryogenic treatment solution increases the resistance of tools and components to wear, abrasion, pitting and spalling. ALNAT™ supply solutions ensure a controlled atmosphere for safety, efficiency and reliability. The ALNAT™ solutions include bulk gas supply, related gas-handling equipment and a range of services related to the generation, use and control of atmospheres in industrial heat processing furnaces. Our process and safety audits optimize the use of heat treatment furnaces and assist in troubleshooting. Additionally, we train heat treatment personnel to ensure safe, smooth and efficient processes. Services include:
The benefits of the ALNATTM HP supply solution include low maintenance costs, reduced capital requirements, lower operating costs and improved core hardness without distortion.
ALNATTM HP supplies nitrogen directly to the high pressure buffer tank at the pressure, flow rate and quality required. Safety procedures are adapted to your operations. The ALNATTM HP solution can be customized depending on buffer sizing, pressure and flow requirements.
Argon and nitrogen gas delivered at pressures up to 400 psi
Patented helium / carbon dioxide quench mixes
Eliminates need for gas compressor
