What are the classifications of industrial gas cylinders?
Author：
According to the structure of gas cylinders, they are divided into adsorption gas cylinders, seamless gas cylinders, dissolved acetylene gas cylinders, glass fiber reinforced plastic gas cylinders, and welding gas cylinders.
Cylinders are classified by volume:
1. Seamless steel gas cylinder (GB5099-94) - The volume range of seamless steel gas cylinders containing permanent gas or high-pressure liquefied gas is 0.4~80L, and the gas cylinder category is also specified. The cylinders with a volume of 0.4~12L are classified as small volume cylinders (15 volume classes), and the cylinders with a volume of 20~80L are classified as medium volume cylinders (11 volume classes).
2. Welded steel gas cylinders (GB5100-94) - The volume range of welded steel gas cylinders containing low-pressure liquefied gas or dissolved acetylene is 10~1000L, which is divided into 14 volume classes
3. Dissolved acetylene cylinders (GB11638-1989) - At present, dissolved acetylene cylinders manufactured in China are of welded structure, with a nominal volume of 10~60L, which is divided into five volume classes: 10, 16, 2540 and 60L.
4. Liquefied petroleum gas cylinders (GB5842-1996) - The volume of liquefied petroleum gas cylinders is divided into three levels: 23.5, 35.5 and 118L, and the corresponding volume levels are divided into three levels: 10, 15 and 50kg.
5. Aluminum alloy seamless gas cylinders (GB11640-1989) - The volume range of aluminum alloy seamless gas cylinders is 0.4~50 liters and divided into small volume "marine and medium volume gas cylinders are classified into 23 levels.
