Basic parameters of Oxygen Cylinder. The standard of the gas storage capacity of the oxygen cylinder is the pressure resistance.
The upper limit of the pressure of a conventional oxygen cylinder is 15Mp (megapascal), which is 147 atmospheres when converted to atmospheric pressure. The test value of Oxygen Cylinder's withstand voltage is 22.5Mp.

The pressure in the conventionally filled Oxygen Cylinder cylinder should be around 12~15Mp. 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.
Use precautions. The distance between the Oxygen Cylinder and the open flame should be no less than 10 meters, not close to the heat source, and not exposed to sunlight. It should be stored in a dry and cool place, and the gas cylinder should not be hit. Oxygen bottle mouth, inhaler, pressure gauge, and interface threads are strictly prohibited from being stained (contaminated) with grease.
When the Oxygen Cylinder is transported and loaded and unloaded, the bottle valve should be closed tightly, the cap should be tightened, and the product should be handled with care. During the process of moving, parking and using the oxygen supply, please pay attention to the protection of the bottle body and the valve to prevent the gas bottle from being overturned, so as to avoid damage to the accessories.
If you find air leakage during use, please close the valve of the gas cylinder of Oxygen Cylinder immediately, please do not repair it yourself. It is strictly forbidden to disassemble its bottle valve, valve switch, pressure gauge and other valve parts without permission. Users are strictly prohibited from filling with oxygen without permission.
Through the above introduction and analysis of the Features of Oxygen Cylinder, hope it helps you.
