Industrial gases refer to oxygen, nitrogen, argon, neon, helium, krypton, xenon, hydrogen, carbon dioxide, acetylene, natural gas, etc. Because these gases have inherent physical and chemical characteristics, they play a pivotal role in the national economy, and the speed of promotion and application is very fast, almost penetrating into all walks of life.

The traditional industries with a large amount of industrial gas are: steelmaking, iron making, non-ferrous metal smelting, chemical fertilizer production, ethylene, propylene, polyvinyl chloride, artificial fiber, synthetic fiber, silicone rubber products, cable and synthetic leather and other petrochemical industry, mechanical industry welding, metal heat treatment, helium leakage, etc., floating glass production, etc. As these traditional industries have grown rapidly in recent years, the consumption of industrial gases has also reached a peak.

Industrial gas consumption is booming in the following industries: Coal mine fire fighting, oil mining, coal gasification and coal liquefication, glass melting furnace, cement production kiln, refractory material production kiln, brick kiln and other industrial furnaces, food quick-freezing, Food gas controlled packaging, beer preservation, optics, fuel in the national defense industry, superconducting material production, electronics, semiconductor, optical fiber production, agriculture, animal husbandry, fish industry, waste water treatment, bleaching pulp, waste incineration, crushing waste tires and other environmental protection industry, construction, meteorology, culture, cultural relics protection, sports, public security case solving, cold knife in the medical and health care industry, seriously ill patient inhalation Oxygen, hyperbaric oxygen therapy, cryogenic refrigeration of human organ tubes, anesthesia technology and oxygen bar, etc.

Industrial gas applications are being tested in solid nitrogen production, fuel cell production, magnetic material production, ultra-fine processing, natural gas power generation, compressed natural gas vehicles, hydrogen vehicle production, etc.

Industries with high consumption of industrial gas, such as iron and steel, fertilizer, chemical industry, glass and chemical fiber industry, have built their own gas production equipment and implemented the business policy of self-production and self-sales. Some industries with low consumption of industrial gas mainly rely on the market to purchase industrial gas. As a result, the liquid market for industrial gases is booming, and the application fields are becoming more and more extensive.
