What is a hydro test of a CO2 tank?
Hydrostatic (Hydro) Testing is a process where components such gas cylinders are tested for strength and leaks. Aluminum CO2 cylinders require testing every 5 years. At the time of testing, a date stamp will be imprinted into the cylinder near the top of the tank.
How often do CO2 tanks need to be hydro tested?
every five years
All DOT-3AL marked CO2 cylinders are to be inspected and hydrostatically re-tested every five years as required in CFR Title 49 Part 180.205(c).

How long is hydro test good for?

What is hydro test procedures?
A Hydrostatic (HYDRO) test is a type of pressure test in which process components such as pipelines, piping, pressure vessels and fuel tanks can be tested for their strength and leaks. The procedure involves filling the test system with a liquid (Water) and pressurising it to a specified test pressure.
Can you use an expired CO2 tank?
While the gas in the CO2 cylinder does not expire, our cylinders need to be checked for quality assurance purposes by a certain date, which can be found at the bottom of cylinder. For best use, we recommend storing your cylinder at room temperature.
