What gases are mainly filled in non refillable welded steel cylinders for industrial use

Freon refrigerants such as R134a, R410A, R22, etc. are commonly used for initial filling of air conditioning and refrigeration equipment.

Industrial non refillable welded steel cylinders are mainly filled with low-pressure liquefied gases, including the following categories:

Refrigerants: Freon refrigerants such as R134a, R410A, R22, etc. are commonly used for initial filling of air conditioning and refrigeration equipment.

Chemical raw materials such as ammonia, chlorodifluoromethane, propylene, propane, etc. are used in specific process steps of chemical production.

Special gases such as dimethyl ether and bromomethane are used in agriculture, disinfection, and other fields.

It should be noted that this type of gas cylinder is strictly prohibited from being filled with compressed gas, and the filling gas must comply with the provisions of "Non refillable Welded Steel Cylinders for Industrial Use" (GB/T 17268) and relevant safety standards.
