How often are steel and aluminum cylinders tested?

Steel and aluminum cylinders used for compressed gases are required to undergo hydrostatic testing every 5 years. This testing ensures the integrity and safety of the cylinders, as it checks for leaks and potential weaknesses in the materials caused by stress, corrosion, or damage. The 5-year interval is established by regulatory organizations to maintain safety standards in the handling and storage of these gas containers. The emphasis on a 5-year cycle allows for a balance between safety compliance and economic feasibility for users of gas cylinders.

Other testing frequencies, such as every 3 years, once a year, or every 10 years, do not align with the requirements specified by regulatory authorities, which is why they are not considered valid options. Recognizing the importance of the correct testing interval is crucial for ensuring the reliability and safety of compressed gas systems.
