Oxygen is manufactured by air separation.The purity is 99.5%.After the post-processing, manufacturing 99.99% purity oxygen.
oxygen is used in medical applications, metal cutting and welding, as an oxidizer in rocket fuel, and in water treatment.Oxygen is used in oxyacetylene welding burning acetylene with O2 to produce a very hot flame. In this process, metal up to 60 cm thick is first heated with a small oxy-acetylene flame and then quickly cut by a large stream of O2.

According to customer needs
Oxygen is one of the components of air, colorless, odorless, and tasteless. The hydrogen density is greater than air and has a density of 1.429 g/l under standard conditions (0 ° C and atmospheric pressure 101,325 Pa). The method for large-scale production of hydrogen is to fractionate liquid air. First, the air is compressed. After it is expanded and expanded, it is cooled to liquid air. Since the boiling points of rare gases and nitrogen are lower than oxygen, after fractionation, the remaining liquid oxygen Can be stored in high pressure steel cylinders
