Outage Tubes
Outage tubes provide a vapor space of the desired volume in cylinders containing liquefied gases, so that liquid in the cylinder can expand if the temperature increases. Without enough vapor space, a small temperature increase can cause the liquid to expand and increase the pressure dramatically.
When used in liquefied gas sampling, the sampling valve can provide 80% of the standard volume tube (reserve 20% of the evaporation space), or an optional outage tube adaptor for separate installation.
