What material are disposable refrigerant cylinders made from?

Disposable refrigerant cylinders are made from steel due to its strength and ability to withstand the high pressures associated with refrigerants. Steel is a durable material that provides the necessary structural integrity to safely contain gases under pressure without the risk of rupture or leakage. It also has good resistance to corrosion, especially when treated with protective coatings, making it suitable for containing various types of refrigerants that could be harmful or reactive.

While aluminum is also used for some types of refrigerant containers, it is typically not used for disposable cylinders because it can be less robust in high-pressure applications compared to steel. Plastic, on the other hand, is not suitable for pressurized gas cylinders since it cannot safely contain high-pressure refrigerants. Composite materials tend to be utilized in more specialized applications, such as lightweight or high-pressure situations, rather than in standard disposable refrigerant cylinders. Therefore, steel is the appropriate material choice for these cylinders due to its reliability and safety in containing refrigerants.
