How to refill the gas bottle
Gas bottles are a common industrial and daily necessities, widely used in liquefied petroleum gas (LPG), natural gas (CNG) and other fields. Correct refilling not only ensures safety but also extends the life of your gas cylinder. This article will introduce in detail the filling steps, precautions and related data of the gas bottle.
1. Gas refilling steps for gas bottles

1.Check gas cylinder: Before filling, be sure to check whether the appearance of the cylinder is intact and whether there is any rust, cracks or deformation. Also confirm whether the valve of the gas cylinder is normal.
2.Choose a gas station: Choose a regular gas filling station and ensure that the gas filling equipment meets safety standards.
3.Connect gas equipment: Connect the gas filling gun of the gas filling station to the valve of the gas cylinder to ensure good sealing.
4.Start filling up: Turn on the switch of the air filling gun and add air slowly. Pay attention to the pressure gauge during the filling process to avoid overpressure.
5.Complete filling: After gas filling is completed, turn off the gas filling gun switch, disconnect it, and check whether the gas cylinder valve is closed tightly.
2. Precautions for filling gas bottles
1.Overpressure gas filling is prohibited: The design pressure of the gas cylinder is fixed, and overpressure filling may cause the cylinder to explode.
2.Avoid high temperature environment: When refilling, it should be done in a cool and ventilated place, away from direct sunlight or high temperature environment.
3.Regular testing: Gas cylinders should be sent for inspection regularly to ensure their safety.
4.Keep away from fire: Smoking or using open flames is strictly prohibited during refilling.
3. Relevant data of gas bottles
| Gas cylinder type | Common capacity (kg) | Design pressure (MPa) | Gas filling time (minutes) |
|---|---|---|---|
| Liquefied Petroleum Gas (LPG) | 15-50 | 2.1 | 5-10 |
| Compressed natural gas (CNG) | 10-20 | 20 | 3-5 |
| oxygen cylinder | 10-40 | 15 | 5-8 |
4. Frequently asked questions about gas bottles
1.What should I do if there is air leakage when refilling?: Stop filling the gas immediately, check whether the valve and connections are loose or damaged, and replace the sealing ring if necessary.
2.Is the cylinder pressure insufficient after refilling?: It may be that the gas pressure at the gas station is insufficient or the gas cylinder valve is not fully opened. It is recommended to replace the gas station or check the valve.
3.How long is the service life of a gas cylinder?: Generally 10-15 years, specific subject to test results.
5. Summary
The process of refilling a gas bottle may seem simple, but it involves many safety details. Correct operation can not only ensure personal safety, but also improve the efficiency of gas cylinder use. I hope this article can help you better understand the methods and precautions for refilling gas bottles.
