I worked at an ASME certified company for 4-5 years, built LOTS of pumps and pressure vessels, had our own test chamber in-house, the AI came to our plant twice a week. We even built stuff to TUV standards, the German equivalent to ASME.
SON bought a Quincy #325 80 gallon tank of questionable condition, was new in 1964, it's first home was in the tire shop at the DECK TRUCK STOP in Geneseo, I'll, Exit 19 on Interstate 80, my old hometown, it was removed, used as a backup compressor at a 3-4 bay body shop, running air tools, like sanders non-stop, spraying paint, next home was in a small machine shop, machine tools use a surprising amount of compressed air! By this time it was getting tired, some cheap unskilled repairs were done with blue RTV splattered all over everything. SON did some much needed repairs, like new valves, rebuilt the unloaded, surprisingly the pistons, rings and cylinders were in usable condition. The thing sat in his garage for 3-4 years, directly across the wall from his head sleeping in his bed. Pumped up to 150 psi.
Anyhow, the motor, an old single phase 220V 5 hp and the old tank were scrapped, the compressor will be installed on a new or newer tank, but the 58 year old compressor will run again.
My Uncle was absolutely TERRIBLE with tools, trucks, tractors, and anything else mechanical. He bought a new 2 or 3 hp 20 gallon cheap 120V compressor for his attached garage, to air up the occasional low tire to get him to the tire shop in town. Most times the compressor was left plugged in, and "On" so it was aired up. The compressor was 5+ years old, maybe more, had never been drained, stored in the corner of the 2 stall garage, the corner by the exterior wall and the interior wall between the living room and garage. Uncle and aunt get home from somewhere, hit the button on the garage door opener, the compressor is sitting just inside the garage door, totally mangled, tank mostly turned "inside-out", further investigation showed the exterior garage wall was blown OFF the foundation for 10 feet, close to a foot off the foundation, the interior common wall between garage and living room also off the foundation, 10 ft in length and a foot or more off the foundation, there was a basement under the living room.
DAD got the remains of the compressor, the pump and elec motor were salvageable. But the sight of the inside-out tank has left a long lasting respect for the power of compressed air with me. I've got portable compressed air tanks I'll probably NEVER use again.
