Helium can be stored in a high-pressure tube trailer for an extended period, practically many years, provided the valves and seals remain properly maintained. Because helium is an inert noble gas, it does not degrade or change its chemical makeup over time.
The limiting factor for storage duration is not the gas itself, but rather the leakage rate through valve stems, seating, or O-rings.

Key Considerations for Long-Term Helium Storage:
Leakage: While helium is known to leak (even diffusing through some materials), modern steel tube trailers, when properly sealed, experience very low loss rates.
Tube Maintenance: Pressurized trailers undergo safety checks and retesting, sometimes after 5 or 10 years, which would identify any structural issues.
Storage Duration: If the tube trailer is parked, unused, and kept in a secure, dry, and cool location, the helium can remain in the cylinders indefinitely or until the container rusts or the seals degrade, which could take decades.
