Application: Although argon accounts for only less than 1% of atmospheric argon as an inert gas abundant in industrial production appears increasingly important. More stringent requirements in the form of an inert atmosphere of argon is more suitable than nitrogen. Argon is mainly used in the steel industry, in the production of stainless steel, argon is blown into the furnace stir the molten metal to displace the other gases. Argon is also often used to form a protective atmosphere in welding, metal fabrication, aluminum processing, micro-electronics, and other industries. Argon is mainly used in the following industries: Stainless Steel Products / Chemical Analysis / welding / Electronics / Lighting / aluminum processing Packaging: cryogenic liquid storage tanks / Dewar tanks / cylinders / 40 ~ 50L seamless cylinder storage and transport: argon All gas products, both gaseous and liquid can be stored way, you can also use piped-style container-shipping direct delivery.
