Have a look at this video of air receiver failure captured by home security

commentary and watch to the end to see photos of the remains of
the air receiver. If I were you I would just buy another unit rather
than run
the risk of using a corroded pressure vessel. New ones are very affordable.
Look how the end caps separated cleanly off that thing. That wasn't
rust. I'm worried now, better put mine on craigslist.

Or hover over it during each filling? wink I'd like to see all the
edges of that tank to determine just what -did- happen to it.

If the guy's father hadn't been right next to it, it would have missed
him altogether.


If you look close at the still images at 2:45-2:47 it sure looks like a
new weld with the paint blackened and very clean edge. Straight in line
with the air fitting at the edge of the tear. I'm wondering if it pin
holed, they cleaned and welded it but didn't get proper penetration, and
the tank tore apart in the HAZ.
As for the end caps, that's common in a pressure vessel failure
(actually intended as well) The metal tears away at the weld.
