Groups of HSBC, industrial gas plant _ _ industrial oxygen oxygen supply industry

Qun Li Feng, industrial gas plant industrial oxygen supply _ _ industrial oxygen provided by the HSBC Group. We are Qingdao Qun Li Fung Ltd. (www.qunlifeng.cn) at: Qingdao specializes in: nitrogen, 175 Dewar tank, car gas, cryogenic insulation cylinder, high purity gases in the air is the main component oxygen and nitrogen. The use of oxygen and nitrogen having a boiling point different industrial oxygen, production of oxygen from air, said air separation method. First, the air is pre-cooled, purified (to remove the small amount of moisture in the air, carbon dioxide, acetylene, hydrocarbons and other gases and dust and other impurities), is then compressed and cooled to become liquid air. Then, the boiling point of oxygen and nitrogen in different prices industrial oxygen, liquid air in a distillation column to the evaporation and condensation repeatedly, oxygen and nitrogen separated industrial oxygen offer to give pure oxygen (99.6% purity) and nitrogen (up to 99.9% purity) to prevent oxygen bottle explosion safety requirements as follows: (1) Inflatable: Inflatable front of the cylinder must be strict inspections, where the following conditions shall be inflated: More than test date or test date is unknown; paint color words is unclear, unable to identify the type of gas; no residual gas bottle; cylinder valve damage, leakage; bottle cylinder valves and joints, especially grease contamination; bottle corrosion or mechanical damage; safety accessories incomplete, damaged . Inflatable process to strictly abide by the rules
