Propane tanks truly are the workhorse of energy storage. They have a big job — making sure your liquid propane remains in one place without evaporating.

You are watching: How much pressure in a propane tank

It’s tempting to desire to fill her propane tanks as high together possible, however how high is too high? The last think you’d want to do is have actually a rupture / explosion on your hands!

Like most things, the quantity of push you have the right to put into a propane tank counts on a large number the factors. The pressure limit is variable for various tank materials and sizes. However, you deserve to expect most propane tanks to have actually a LPG press capacity in between 100 and 200 PSI (source).

Keeping the propane between 100 and 200 PSI ensures that the propane stays in a liquid state.

The devil is, that course, in the details. There are a couple of in its entirety principles us should obtain out of the means before going any kind of further.

Liquid propane tanks will shed pressure in the cooler months, together the frigid temperatures increase the thickness of the liquid.Conversely, castle will get pressure in the name is months together the heat causes liquid propane to expand.

I’m not going to talk about how approximately temperature impacts tank pressure. However, know that if you fill a tank come the brim during cold weather, the press will increase as the weather warms up!

For example, a traditional 20-pound propane tank at 70 degrees will have 145 psi interior pressure. That same tank ~ above a 100-degree job will have actually 172 psi of pressure.


Safety Relief Valves aid Protect You

I’d favor to take it a moment to talk about the security relief valves top top propane tanks.

Since you’re right here reading this article, there’s a an excellent chance the you want to be careful when filling her propane tank, or subjecting it come harsh temperature fluctuations.

The last thing that anyone wants is a propane tank the explodes.

Luckily, the vast majority of commercial and also industrial propane tanks have actually something called a security relief valve. A safety relief valve is a item of hardware designed come prevent damage caused by high pressure.

It’s normally attached come the propane tank’s gas outlet and will permit gas come escape the tank as shortly as the interior pressure access time a mentioned limit.

The most that can take place on propane tanks equipped through a safety and security relief valve is a modest quantity of wasted propane!

One native of caution: if her propane tank lacks a safety relief valve or that valve is not in working order, tank explosions are still possible. If you’re unsure, please call the manufacturer.

What walk a safety and security relief valve look like?

Are friend unsure whether or not your fluid propane tank has a security relief valve? It’s understandable if therefore — lock aren’t adequately significant in most systems.

While valves come in all shapes and also sizes, here is an example of a safety relief valve in the wild.


Eliminating Unnecessary waste

While wasted propane is preferable to exploding propane tanks, it’s still no ideal.

Luckily, you can take steps to avoid bring about wild temperature fluctuations (the most common reason of propane rubbish from security relief valves).

To prevent propane loss, first try shading her propane tank making use of vegetation, an awning, or a dedicated propane cover. Direct sunlight is the second biggest reason of LPG lose in the summertime. Since of this, adequate spanning will substantially mitigate the leakage.

This will assist you mitigate the lot of gas friend lose and also subsequently reduce the variety of trips to choose up a brand-new tank!

What about painting the tank?

A most folks have actually the idea of paint their propane tank through reflective paint to reduce gas loss. If this is a good thought, almost all tanks are already painted this way!

In fact, NFPA 58 claims that propane tanks must be coated in a reflective paint.

If your tank doesn’t for whatever reason, this should be addressed. If you’d like an instance of something that might work, check this tank coating the end on Amazon (affiliate link).

While the above product is designed for fuel tanks, I have been assured that it will work for propane tanks as well.

Watch because that Damaged Tanks

As propane tanks space exposed to the elements, they often rust. This problem compounds over time and also can an outcome in a endangered tank wall.

Simply put, the structural integrity of the tank is lessened when they begin to rust. Likewise, the amount of pressure the tank can handle reduces and the danger of rupture skyrockets.

If you notification that your propane tank is severely rusting, remedy the situation immediately!

You can pick to one of two people refinish the tank (assuming the damage isn’t as well bad) or just buy a brand-new one. If you have a larger propane tank, you could likewise call a professional and ask for your advice.
