Steel Pipe For Gas Cylinder
What is seamless steel pipe for gas cylinders?
Seamless steel pipes for gas cylinders are steel pipes specially designed to withstand high pressure and safely contain gas. These tubes are commonly used in the manufacture of gas cylinders for various applications such as industrial gases, medical gases, and liquefied petroleum gas (LPG).

Seamless cylinder tubes for gas cylinders are divided into the following three categories:
1. Material: Most use 16Mn steel pipes, and some use other high-quality steels.
2. Size: The diameter is generally below 89mm, and the wall thickness is generally below 8mm.
3. Usage: used to make fire extinguishing bottles, oxygen bottles, liquefied petroleum gas bottles, etc.
4. Features: high strength, good safety, high pressure resistance and corrosion resistance.
1. Material: Most use high-quality steel such as 30CrMnSiA, 37Mn, 34Mn2V.
2. Size: The diameter is generally less than 219mm, and the wall thickness is generally less than 20mm.
3. Usage: Used to manufacture CNG (compressed natural gas) bottles, high-pressure oxygen bottles, high-pressure hydrogen bottles, etc.
4. Features: high strength, good safety, high pressure resistance, corrosion resistance, light weight.
1. Material: Most use 30CrMo, 35CrMo, 34CrMo4 and other alloy structural steel pipes or stainless steel pipes.
2. Size: The diameter is generally above 89mm, and the wall thickness is generally above 8mm.
3. Usage: Used to manufacture gas cylinders, industrial high-pressure gas cylinders, etc. in the aviation and aerospace fields.
4. Features: high strength, good safety, high temperature resistance, corrosion resistance and wear resistance.
