Carbon dioxide cylinder

Product description
First, the product name
Chinese name: carbon dioxide cylinder
English name: CO2 cylinder
Second, product introduction
(1) Carbon dioxide bottle is a high-pressure container for storing and transporting nitrogen. It is generally made of alloy structural steel, which is hot-pressed and pressed, and has a cylindrical shape. Used in hospitals, first aid stations, nursing homes, food factories, chemical plants, etc.
(2) The shoulder of the cylinder is marked with the working pressure, test pressure, volume, weight, and other information. The surface is painted in gray and the word “CO2” is written in green.
(3) The standard for the gas storage capacity of carbon dioxide bottles is the pressure resistance.
(4) The upper limit of the pressure of a conventional carbon dioxide bottle is 15Mp (MPa). The atmospheric pressure is 147 atmospheres.
(5) The pressure resistance test value is 22.5Mp.
(6) The pressure inside a conventionally filled cylinder should be around 12~15Mp.
(7) The gas in the bottle cannot be completely used up, and the residual pressure of not less than 0.1-0.2MP should be retained.
Third, common uses
(1) High-purity carbon dioxide is mainly used in the electronics industry, medical research and clinical diagnosis, carbon dioxide lasers, calibration gas for testing instruments, and other special mixed gas, used as a regulator in polyethylene polymerization.
(2) Solid carbon dioxide is widely used in frozen dairy products, meat, frozen foods and other foods that are perishable in transport. It is used as a refrigerant in many industrial processes, such as crushing heat sensitive materials, rubber polishing, metal cold processing, mechanical parts. Shrink assembly, vacuum traps, etc.
(3) Gaseous carbon dioxide for carbonized soft drinks, pH control of water treatment processes, chemical processing, food preservation, inert protection of chemical and food processing processes, welding gases, plant growth stimulators, for hardening molds and cores in casting It is also used as a pneumatic device, and is also used as a diluent for sterilizing gas (that is, a mixed gas of ethylene oxide and carbon dioxide is used as a sterilizing agent, an insecticide, and a fumigant, and is widely used in medical instruments, packaging materials, clothing, fur, bedding. Such as sterilization, bone powder disinfection, warehouse, factory, cultural relics, fumigation of books).
(4) Liquid carbon dioxide is used as a refrigerant, low temperature test for aircraft, missiles and electronic components, improving oil well recovery, rubber polishing and controlling chemical reactions, and can also be used as a fire extinguishing agent.
(5) Carbon dioxide in a supercritical state can be used as a solvent for dissolving nonpolar, nonionic, and low molecular weight compounds, and thus is widely used in homogeneous reactions.

Fifth, the production process
1. Overall flushing type:
Billet sawing and cutting - induction heating - anti-extrusion punching - drawing - picking - closing - heat treatment - external sandblasting - mouth thread processing - internal sandblasting (or phosphating) treatment - hydraulic test - upper valve -Airtight test-spray-drying-inspection-inbound
2, steel pipe spinning forming method:
Steel pipe sawing and cutting - induction heating - spinning seal bottom - milling insole - induction heating - spinning pressure closing - heat treatment - sand blasting - mouth thread processing - internal sandblasting (or phosphating) treatment - hydraulic test - upper valve -Airtight test-spray-drying-inspection-inbound
Sixth, matters needing attention
(1) High-pressure gas cylinders must be kept in separate parts and kept in a stable position when standing upright; keep the gas cylinders away from heat sources to avoid exposure and strong vibration; generally, the volume of gas cylinders in the laboratory should not exceed two bottles.
a. At the shoulder of the cylinder, use the steel stamp to mark the manufacturer's date of manufacture. The cylinder model is working. The pressure and pressure test pressure and pressure test date and the next inspection date, gas volume, and cylinder weight.
b. In order to avoid confusion when using various cylinders, the cylinders are often painted in different colors to indicate the name of the gas in the bottle.
(2) The pressure reducer selected on the high pressure gas cylinder should be classified. The screw buckle should be tightened during installation to prevent leakage. When opening and closing the pressure reducer and the on/off valve, the action must be slow; when using, the switch valve should be rotated first. After opening the pressure reducer; when it is used up, first close the on-off valve, after exhausting the remaining gas, then turn off the pressure reducer. Do not just turn off the pressure reducer, do not close the switch valve.
(3) When using a high pressure gas cylinder, the operator should stand in a position perpendicular to the cylinder interface. Do not knock on the impact during operation, and always check for leaks. Pay attention to the pressure gauge reading.
(4) Oxygen bottles or carbon dioxide bottles, etc., should be equipped with special tools and are strictly prohibited from contact with oil. Operators should not wear clothing gloves that are contaminated with various greases or that are sensitive to static electricity to avoid burning or explosion.
(5) The distance between the flammable gas and the combustion-supporting gas cylinder should be greater than ten meters from the open flame (if it is difficult to achieve, measures such as isolation can be taken).
(6) After use, the cylinder should be kept at a residual pressure of 0.05 MPa or more as specified. The flammable gas should be 0.2MPa~0.3MPa (about 2kg/cm2~3kg/cm2 gauge pressure). H2 should be kept 2MPa to prevent danger when re-inflating, and it can not be used up.
(7) Various cylinders must be regularly inspected for technical inspections. Gas cylinders filled with general gas shall be inspected once every three years; if severe corrosion or serious damage is found during use, inspection shall be carried out in advance.
Note: The above specifications of the cylinder are general reference materials. If you have special requirements, please call 40009 63336, 18563963366.
