My tank is rated to 175 PSI. The compressor cycles up to 140 PSI. I usually test my tank every four years to 300 PSI for one hour using the grease gun methode. It leaves a bit of a mess in the tank but that just rust proofs the bottom. My 30 gallon tank when filled with water takes about 1-1/2 tubes of grease to pressureize to 300 due to elasticity of the steel.
Good safe practise using water for test medium. Due to water in the tank not being drained regularly the designed corrosion allowance can be compromised unknowingly sacrificing the tank wall thickness from the inside.
I bought a 26 gallon 150 psi Cobalt from someone. I'm just gonna lower max build up to 100 psi. Think that will be OK so I don't have to buy all this stuff to test it. I'm just gonna use it to air up my tired and slow out stuff.
I'm guessing tha that you're talking about something like the pump used to fill the reservoir on a PCP air rifle or similar. That will get you the pressure, but you don't want to use air because it's compressible and stores energy causing an explosion if the tank ruptures. Admittedly if you fill the tank with water it shouldn't be that much air, but I'm not risking it with a 60 gallon steel tank (one of my dad's friends was killed when a tire ruptured, MUCH less volume and pressure). WRT to small pumps, I've heard of people using grease guns, but they pump a very small volume and I have no idea how well it works IRL.
@@mpikas a grease gun could work for pumping Grease....... However you can get a bicycle shock pump that can do 300 PSIG off of Amazon for $25. A few ccs of air in known good attached small piping during testing won't matter.... That piping is good for thousands of psig. The rupture would occur at the tank which is full of water Good job
If th factory plate on that tank has the tested data it will say what that tank is rated to. Normally tests are to 150 % of operating system pressure. Most tanks are tested at 200 psi for 30 minutes
Yes, and right now I don't remember what that showed but I wanted to test it to at least 150% of what my current compressor was capable of so I knew for sure it was safe to anything that could accidently happen to it.
People dont know pneumatics and it shows in comments.. same people on the playing the field that say "not HPA it will explode so ill stick to AEG".. they also dont batteries either as id rather take my chances with a loud whistle than whote hot chemical flames when the air hits a ruptured battery.. i mean if we playing tit for tat game.. Most tanks dont rupture to form lift an thrust..thats a tank rocket..most just scare the shit out of you.. your hot water heater is more dangerous than these! Watch those videos, i dont if the show same ones from engineering school to public..but just say they ARE not informing you correctly on the sales pitch just how dangerous BUT most safe they are at same time..
Excellent. Big help to see someone DO it, versus others where they only TALK about it.

Thanks for quick connect fitting info!
You bet!

I have a hand pump that will do up to 3000 psi. It uses a paintball type fitting.

Thank you! Cheers!
You are standing waaaay too close to the test tank. Use 2 gauges in case one is not operating correctly or out of calibration.
I bet those critters are saying wtf is he doing. LoL. TY for video.
I Hope this isn't found footage
What do you mean?
I'm scared to even turn on my 40 Year old air compressor
