That is not a commercial compressor..That is a home residential unit..Those tanks are way thinner.

does'nt matter where they're made......in our shop , a 1000# plus , 120 Gallon T30 "Ingersoll-Rand" did the same xact thing......through a wall & roof to the parking lot.....this work safe link states :

It is not just a air problem.


How can an air receiver tank explode?
During operation, deposits of lubricating oil tend to build up in the line supplying compressed air from the compressor cylinder to the air receiver. As the diameter of the supply line decreases, the already high temperature of the compressed air rises further to a point where it is possible for the contaminant to ignite.

Sparks are then carried into the air receiver where oil from the compressor, which is often present as a mixture with air in the air receiver, burns explosively. As the pressure relief valve is not designed for such an event, rupture of the air receiver vessel is likely to occur. In other air compressor accidents, static electricity sparks have also been identified as a source of fires and explosions.

Now that explosion in your shop or garage might make you wet your pants a little:ashamed:

helluva place to park a compressor.

Holy crap. Guess it's time for a new one.

And a roll or two of duct tape....

at least the shop will be a lot quieter with it out there. maybe i'll try roof mounting mine too.

And thats precisely why you dont patch old, rotten tanks with screws or weld..... Or plumb your shop with PVC. Its also why my 60 Gal is Hilti bolted to the floor.

Pressure vessels are scary stuff when they go boom.

If a compressor decides go blow from a ignition source..It do no think it matters how new or old it is.

That tank in the Aussie link was a rare occurrence. Sure you can have oil in the receiver for any oiled compressor, but 1. getting it to ignition temp under pressure, and 2. getting the proper air:fuel mix to have an explosion is considerably rarer than a rust through situation that were talking about here.

All compressors make water, which creates rust. This is in 100% of compressors and something we all need to address. Being cheap here for the sake of a couple hundred for a new tank (or compressor if its a small one) is crazy.

Suggesting that 150 PSI is harmless is also foolish. Recommending either directly or through personal experience that anyone patches a hole in a rusted tank with a screw or similar is downright dangerous and could have fatal consequences.

Having worked around large industrial compressors and boilers, i can tell you that anyone in the industry treats them with the utmost respect. Ask just about any Stationary Engineer with experience what can happen when things go bad.

I had lunch with my friend who is a retired pressure pipe welder.

He said over the years he probably welded on 40 air tanks, in his shop, for various reasons. Usually because someone broke something off off it. I asked about the explosion risk, he said, "I am still here".

Then he said, "Maybe, but when you've welded on fuel tanks, petroleum pipe lines, and high pressure gas lines, an air tank is not that scary".

You would have to prove to me that any failed compressor tank exploded with just air pressure of 160lbs and not from a explosion..Compressed air gets very hot when it is delivered to the storage tank. which makes me believe that the explosion factor is the cause.

I just need more proof..To me it would be just as rare of a occurrence for either to happen.

Ummm...did you read the link I posted? First hand experience. None of this "I heard about a guy business..." The guy who got clobbered posted about it. With pictures.

Was it a explosion? or just air rupture? Who knows for sure? Just saying..Did I miss that part?

 

[grsthegreat]

those tanks arnt designed to reach 150psi.....it exploded from excessive pressure.

my 80 gal air compressor is bolted down to the floor.
