Extended data:

Gas cylinder refers to a mobile pressure vessel containing permanent gas, liquefied gas or dissolved gas with a nominal working pressure of 1.0~30MPa (gauge pressure) and a nominal volume of 0.4 ~ 1000 L, which can be repeatedly inflated under normal environment (-40~60℃).

Gas cylinder is a kind of pressure-bearing equipment, which has the danger of explosion. Its loading medium is generally flammable, explosive, toxic and corrosive, and its use environment is more complicated and harsh than other pressure vessels because of its characteristics of moving, repeated filling, unstable operators and changeable use environment.

In order to ensure the safe use of gas cylinders, there are some special regulations and requirements besides the general requirements of pressure vessels.
