What will happen to cylinders that are in continuous service beyond 12 years?

Cylinders that are in continuous service beyond 12 years must be discharged and retested to ensure their safety and integrity. This requirement is in place because extending the usage of these cylinders without proper testing could lead to potential risks, such as leaks or failure during operations. The retesting process evaluates the cylinder's pressure integrity and ensures that it meets current safety standards, thereby protecting both users and the environment. This careful regulatory process helps maintain the reliability of gas systems and prevents accidents associated with cylinder failure. Therefore, adhering to these safety protocols is crucial for both compliance and operational safety.
