Manufacturing
Vulcanization-Tires (Tire Curing)	Vulcanization is a curing process that makes natural and synthetic rubber harder and more wear resistant.
Body – Combustion	Combustion processes use oxygen to melt scrap, refine the steel, and heat the furnaces that reheat steel slabs.
Body – Heat Treating	Heat treating processes use hydrogen and nitrogen in annealing furnaces to strengthen and improve formability of the steel. We offer hydrogen in non-micro bulk form.
Body – Welding	Welding processes use argon for steel.
Body – Heat Treating, Welding & Combustion	Welding processes use carbon dioxide for auto bodies.
Oxy-Fuel (in Glass Melting)	Oxy-Fuel Conversion of Glass Furnaces
Oxy-Fuel (Glass Forming)	Oxy-Fuel impart the finest finishing after forming
Oxy-Fuel (in Clinker Manufacturing)	Oxy-Fuel Enhanced combustion in kiln will ensure the best fuel economy and cleaner emission
Welding	Most commonly used shielding gas, and is the only truly inert gas commonly used in welding.
Welding	CO2 decomposes to CO and O2 at welding temperatures, producing an oxidizing effect similar to a combination of argon plus 0-5% O2.
Welding	O2 is added to shielding gas, where it helps produce a more stable arc, improves wetting of the weld edges and reduces weld spattering.
Heat Treating	Nitrogen-based protective atmosphere for their furnaces.
Heat Treating	Atmospheres may be blended with small quantities reactive gases such as hydrogen.
Injection Molding (Plastic)	Nitrogen assisted injection molding enhances finishing quality of plastic products and also reduces the cycle time
Spot Cooling (Plastic)	Liquid CO2 assisted spot cooling offers attaining the best possible quality and operational flexibility
Alkaline Extraction (Pulp and Paper)	Reinforcement of O2 enables manufacturers Increasing the bleaching effect and decreasing the chemicals which results in large savings of Chlorine Dioxide and operational flexibility
Delignification (pulp and paper)	Oxygen assisted delignification enables attaining the highest brightness and lower chemical consumption
Surface Treatment by Thermal Spray	This noble art of surface coating ensures best attainable coating quality
Ground Freezing (Construction)	Soil-freezing with LIN has become a standard procedure for treating unstable soil and groundwater control.
Concrete Cooling (Construction)	Ensures uniform temperature distribution during concrete cooling eliminating the possibility of internal crack.
