How long after manufacture date may an ASME propane container be used before recertification is required?

An ASME propane container does not require testing or recertification after its manufacture date, meaning there is no specified limitation on its usable lifespan in this regard. The absence of a recertification requirement can be attributed to the robust design and construction standards mandated for ASME containers, which ensure their safety and integrity over time when properly maintained and used within their intended purpose. This means users are not pressured to schedule recertification within any fixed time frame as long as the container remains in a good operational condition.
