Seamless steel cylinders are used to store high-pressure oxygen, gas, liquefied petroleum gas, etc. Safe storage and transportation of steel cylinders Gas steel cylinders generally contain permanent gas, liquefied gas or mixed gas. The cylinder management of gas cylinder filling unit, gas cylinder inspection unit, gas cylinder use sheet (including factories, laboratories, hospitals, schools, disease control centers, electronic rooms, clean rooms, industrial institutions, etc.), bottled gas and gas cylinder distribution units is in urgent need of improvement, and the safety management of transportation and storage of gas cylinders should be strengthened.

Gas cylinders in a broad sense shall include disposable or repeatable mobile pressure vessels with different pressures, volumes, structures and materials for storing and transporting permanent gases, liquefied gases and dissolved gases.

Steel seamless gas cylinders are made of steel billets by stamping and stretching or seamless steel tubes by hot spinning and closing. The bottle body is made of killed steel smelted in alkaline open hearth furnace, electric furnace or oxygen blowing alkaline converter, such as high-quality carbon steel, manganese steel, chromium molybdenum steel or other alloy steel. It is used to contain permanent gas (compressed gas) and high-pressure liquefied gas.
