Classification 

GB5099 steel seamless gas cylinders are divided into three categories according to the physical state of the loaded medium.
   ♦permanent gas cylinder
     A gas with a critical temperature below -10 ° C is called a permanent gas, and a gas cylinder containing a permanent gas is called a permanent gas cylinder. For example, cylinders containing oxygen, nitrogen, air, carbon monoxide, and inert gases are examples of this type.
  ♦ liquefied gas cylinder
    The various gases whose critical temperature is equal to or higher than -10 ° C are gaseous at normal temperature and normal pressure, and become liquid after being pressurized and cooled. Among these gases, some have higher critical temperatures (above 70 ° C), such as H₂S, ammonia, propane, liquefied petroleum gas, etc., called high critical temperature liquefied gases, also known as low pressure liquefied gases.
 ♦dissolved gas cylinder
  This cylinder is a cylinder for acetylene. Since acetylene gas is extremely unstable, especially under high pressure, it is easy to polymerize or decompose. The acetylene after liquefaction is slightly vibrated, which will cause an explosion. Therefore, it cannot be filled in a compressed gas state, and acetylene must be dissolved in a solvent (common acetone). Medium, and filled with a porous substance (such as calcium silicate porous material, etc.) as an absorbent.
