What kinds of materials are classified into seamless gas cylinders

Steel cylinders are steel cylinders made of steel billets that are stamped and stretched or seamless steel pipes that are hot-spinned to close the mouth and bottom. The material of the bottle body is killed steel smelted by a basic open hearth furnace, electric furnace, or oxygen-blown basic converters, such as high-quality carbon steel, manganese steel, chrome-molybdenum steel, or other alloy steel. It is used to hold long-term gas (compressed gas) and high-pressure liquefied gas.

It is a steel cylinder made of steel plate as raw material, stamped and welded. The material of the bottle body and pressure components is killed steel smelted by an open hearth furnace, electric furnace, or oxidation converter, and the material requires good stamping and welding performance. These cylinders are used to hold low-pressure liquefied gases.

Cylinders made of glass fiber plus binder winding or carbon fiber. Generally, there is an aluminum inner cylinder, whose function is to ensure the airtightness of the gas cylinder, and the pressure-bearing strength depends on the outer cylinder wound with glass fiber. This type of gas cylinder is mostly used to hold compressed air for breathing due to its good heat insulation performance and lightweight. , for firefighting, toxic areas, or oxygen-deficient area workers to carry and use with a mask. Generally, the volume is small (1-10L), and the inflation pressure is mostly 15-30MPa.
