What is a gas cylinder?

Gas cylinder refers to a mobile pressure vessel with a bottle-shaped main structure, which is usually filled with gas (can be compressed gas, liquefied gas, dissolved gas and adsorbed gas, etc.). Gas cylinders are widely used. Whether in the field of production or in the field of life, we are almost inseparable from the gas cylinder.

Gas cylinder is a kind of pressure equipment, with explosion risk, its loading medium is generally flammable, explosive, toxic, corrosive and other characteristics. The use environment is also more complex and hostile than other pressure vessels due to its characteristics of movement, repeated charging, operation and use of non-fixed personnel and changes in the use environment. Once the gas cylinder explodes or leaks, there will often be fire or poisoning, and even catastrophic accidents, resulting in serious property losses, casualties and environmental pollution.

In order to ensure the safe use of gas cylinders, in addition to requiring gas cylinders to meet the general requirements of pressure vessels, there are also some specific regulations and requirements.
