I built a 7 gallon air tank, I have only taken it up to 120 psi (everything seems fine) and am a little leery to take it to 200 psi. The tank is 6x6x40 square not round. It is made of 3/16s plate. How much actually force in pounds am I up against when the tank is at 200 psi?

It also depends on the shape of the tank. A round tank will always hold more pressure than a square or rectangular tank...

Photos??

my friend built a few tanks the same way last year. i believe his are 4x4 square tubing also with *i think* 3/16 wall. he ran to 200 all the time with no problems.

hell even now fill it with oil/or water to 99% then fill the rest with air. If something does blow, it will not be explosive.

Let me run a test on that tank for you.
brb with numbers

Ive been wondering about this as well. I was thinking about welding up my frame rails and capping them off to be my tank

Also do those pictures show how much flex I am gonna see at 200 psi?
No that is if I remember 180:1 deflection ratio

so if 4" in the pic that is 1/90th of an inch on the tank

Holy crap, ok well I have had it upto 120 all winter long with no problem. Whats the difference from 120 to 200? Also what is most likely to happen, should i turn the comp on a stand back? or is that a bad idea?

14.4Tons

Like I said fill it to the top most edge with oil or watter then fill the rest with air to 200 and stand back,

Watter/oil can not compress at those pressures so no energy is stored.

So when something gives it will not be explosive.
