According to one of the engineers that I work with, an ASME certified pressure vessel is built with a certain steel (carbon content or something) that is supposed to not "blow" open upon rupture.It would simply split an opening to relieve pressure. Rusted thru tanks will simply create a pin...

I agree with testing the tanks every 5 years. I don't know what the rule is here in Nebraska, but this is just in a shop behind my house, not a commercail business. Once I get it tested, cleaned, painted, and all the new pop off's, pressure switch and gauge installed, I plan to be pretty...

I had talked with the local sandblaster, asking him what his experiences were with pressure tanks. He said he does them all the time, and the old units like mine, didn't have paint baked on or powder coated and didn't take a whole lot of pressure to get the paint off...and he never saw a problem...

Here is it. I got it for $450 and was 1hr drive away from me. I feel I did ok on the price, but wasn't by no means a steal. But these old ones, as long as they are taken care of, will run forever, IMO. The thing is a monster. Yes, it is a ASME tank, and I had even thought about not having it...

Thanks guys. Already planning to put on new gauge, two new relief valves and a new pressure switch. I'll probably even hit it with a DA and give it a fresh coat of paint to make er look nice again before I'm all done with it.

Check out Solberg intake filters and silencers. They seem to be reasonably priced on Amazon. I'm going to order one for my Rolair soon. I believe most of them are also a form of a tube silencer as well...They also got a decent website to look up different sizes and what not.

So I bought this old Rolair compressor at a good price...80 gal, 2 stage, 175psi.....turns out to be about 29 years old. Still working good. Pumps up and what not. No water when I drained the tank, but doesn't mean it never did have water in it. So I been reading about testing these old tanks...
