Industrial Gas Cylinder Oxygen Cylinder Nitrogen CO2 Gas Cylinder


Industrial gas cylinders are containers used to store, transport and supply various gases. They are usually made of high-strength materials such as steel or aluminum alloys to withstand high pressures and harsh environmental conditions. Industrial gas cylinders come in different capacities and sizes to suit different application needs. They go through a strict design and manufacturing process to ensure their safety and reliability, and comply with relevant international standards and regulations. The exterior of gas cylinders is usually coated with a corrosion-resistant and protective coating to increase their service life. In addition, they are equipped with various safety devices, such as pressure relief valves and explosion-proof devices.

1.Read the instructions before use.
2.High-pressure gas cylinders must be stored in separate locations, away from heat sources, and away from exposure to sunlight and strong vibration.
3.The pressure reducer selected for high-pressure gas cylinders must be classified and dedicated, and the screws must be tightened during installation to prevent leakage.
4.When using high-pressure gas cylinders, the operator should stand at a position perpendicular to the gas cylinder interface. It is strictly forbidden to knock and hit during operation, and check for air leakage frequently, and pay attention to the reading of the pressure gauge.
5.Oxygen cylinders or hydrogen cylinders, etc., should be equipped with special tools, and contact with oil is strictly prohibited. Operators should not wear clothing and gloves that are stained with various oils or prone to static electricity, so as not to cause combustion or explosion.
6.The distance between flammable gas and combustion-supporting gas cylinders and open flames should be greater than ten meters.
7.The used gas cylinder should leave a residual pressure of more than 0.05MPa according to the regulations. The flammable gas should remain 0.2MPa~0.3MPa (approximately 2kg/cm2~3kg/cm2 gauge pressure) and H2 should remain 2MPa.
8.Various gas cylinders must undergo regular technical inspections.
