Steel and aluminum air cylinders must be hydrostatic tested every how many years?

Steel and aluminum air cylinders are subject to regulations that dictate the frequency of hydrostatic testing to ensure their safety and integrity. The correct interval for hydrostatic testing these cylinders is every 5 years. This testing is crucial because it assesses the structural integrity of the cylinders under high-pressure conditions and ensures that they are safe for continued use in various applications, including firefighting.

The 5-year cycle provides a balance between safety and the practicalities of maintenance. It helps identify any potential issues like corrosion or structural weaknesses that could arise from regular use or environmental factors. Adhering to this testing schedule reduces the risk of failure during operation, ultimately safeguarding the lives of firefighters and those they serve.

This interval is established by guidelines from organizations such as the Department of Transportation (DOT) in the United States, which set standards for the transportation and storage of hazardous materials, including compressed gases. It is vital to follow these established time frames to ensure compliance and safety in the handling of these air cylinders.
