How to Hydro Pressure Test Air Tank | Compressed Air Tank Hydrostatic Test
HTML-код
- Опубликовано: 9 июн 2024
- We hydro pressure test this Ingersoll Rand air compressor tank to make sure that there isn't any holes or weak welds due to corrosion. This is something you should always do with unknown history tanks or older tanks that are returning to service.
Fill the tank with water and install a gauge. Using a pressure washer, grease gun/fitting, or plumber's pressure pump, fill the tank with air to get the pressure to 1.2X or 1.5X of the tanks working pressure. Let it sit for a few hours to verify that there isn't a leak or other structural damage that won't hold pressure.
Remember, compressed air is very dangerous and contains huge potential energy.

Nice video I learned something new today..
Yea I didn’t know about it either until I was researching about rebuilding compressors. Apparently rusted out tanks and explosion are common with old tanks.
This is great! Going to do this on my very old tank.
very nice explanation of the testing.
Good video. I would suggest not doing any types of testing like this inside a building.
If tank did let go, well it wouldn't be catastrophic but could get everything wet.
You do not need to let it sit for a couple of hours. 15 minutes is more than enough. Reason being is even a small pinhole leak will be enough to visually see on the guage that the pressure has gone down since water is not compressible.
But I understand the reason for wanting it to sit for a couple of hours.
Yea I wanted to make sure. Plus I had to do family stuff so just left it to ensure no leaks in the fittings, etc.
i don't know about metal pressure vessels but it seems like it would create undue stress after long periods
Wow you can test with the compressor and all the stuff connected like that?
Yea, the check valve is supposed to keep it all in tank.
i need the fitting to connect my pressure washer to the tank ?
I used a quick connect for my rotation pressure washer head. It’s standard NPT thread so you need coupler. amzn.to/40W3W8P
Have you gotten your air cooler installed yet?
Yea I got a video on it.
💪👍💯
You are close to failure of a few things here. The 1/2 in valve is ok, iffy on the street el, and the over pressure valve should have tripped. Good test though, be safe.
there are a few vids about tanks letting go -some are very bad.
That’s the beauty of water tests. No potential energy under hi pressure except a squirt then just flowing water.
@@TunerwithKids I agree, but could overstress and damage the fitting or valves or whatever is not made to take that pressure.
Just an FYI. Just be aware of the whole picture. I fill my scuba tanks until the paint cracks, and back it off 50lbs.
Yea when I started the test, that was my main concern, the check valve. It’s rated for 500 psi so I was below. I would have done the test when I had the bare tank stripped but didn’t know about until I had already reassembled the new valves.
Beautiful! 😊😊😊😊!! Do not waste your time - Promo`SM!
You cannot properly hydrostatic test the tank with the safety release valve on. For a proper hydrostatic test you must exceed the rated PSI of your safety valve by 1.5 to 2. The idea is that you are testing to a safety factor (the 1.5 to 2) above the maximum pressure of your tank, which is the safety release valve pressure. That in turn should be higher than your cut-out pressure switch.
I think I tested it up to 270psi. That’s more than 1.5x the 155psi the tank holds. It held that pressure for 4+ hours with the one-way check valve still on. I did my research and that OE one way check is good to like 300+ psi. There isn’t a safety relief on the tank in my test, the safety was part of the switch assembly which I removed for the test gauge. There is a safety on the one way check, but that’s on the compressor side, not the tank side of the valve.
