Helium tanks are industrial tanks made of aluminum containing helium – a chemically inert and non-flammable gas. The tanks are an everyday essential for balloon inflators and are usually refillable. However, in the recent times, it is observed that some helium tanks are not refillable which is really not feasible. It is impossible to pile up empty helium tanks every time. Another important thing happens at times – they ask you to perform hydro testing.
Let’s check out why hydro testing is important –
When you are about to refill your helium tank, it is of vital importance to check for any hairline fractures in the metal body. Hydro testing is a process that puts the tank under high-pressure conditions. So, if the tank was damaged some way, the test indicates the danger and warns you not to refill it.
Sometimes, you may find a star and a plus sign beside the date. The star mark indicates that you can refill the tank every 10 years and plus allows you to add more pressure to the helium tank.
What if there is no valve to tell you that you need to refill –
Well, if you don’t have valves, you need to keep a track of the balloons you have used as there is a general measure of how many balloons can be blown by a helium tank. A large tank fills up to 125 18” metallic balloons or 110 11” latex balloons. So, if you have filled 2 bags of large balloons or 4 bags of standard size balloons, know that you are close to refill. A better option is to purchase a valve to indicate you the pressure in the tank. This way, you will be able to read the tank pressure and save you from running out of helium at an emergency hour.
Experts suggest to buying refillable helium tanks as they are more feasible and easy to use and refill. Helium is an inert gas and can be stored conveniently in a well-ventilated, cool and dry place. It is perfectly safe to store helium in these aluminum cylinders as it is rust and corrosion resistant.
