Actually, 120PSIG is 135 PSI absolute (plus 15psi for static atmospheric pressure). A tank the size would have to have walls 5/8" thick to handle the stress. Vacuum is a very different thing than pressure, that tank probably only has 1/4" walls as vacuum would compress the whole tank together.

 

So Ford_six, is that another vote for large BBQ grill?

I am pretty sure you are correct on the 1/4" steel, as I was able to pick up one end of ths tank. It is huge, and if it was 5/8" I doubt I would be able to budge it at all!

THANKS TO YOU ALL FOR YOUR REPLIES!

BBq idea sounds great(spring fever)

 

I got some new info on this tank and wanted to see what the story might be from all the experts here

This is what the cert label says:
MAWP 137 PSI @150F
MDMT -20f @137 psi
YR 1999
WC 100 SH165 HD 135

I have contacted the manufacturers engineering dept. (lft msg) but i thought some of you might be able to decode this label.

My only guess is;
MAWP = maximum working pressure

Anyone know what the rest of these mean.

p.s. Don't worry I won't hook it up to pressure until I am assured by manufacturer it is OK and even then I will hydrotest it first.
The set comes with a huge vaccum pump that has a 480V three phase motor. Anyone interested in that?

 

Ed, the data plate says you can use this rcvr for pressures less than 137 PISG @ temps of less than 150* F. and greater than -20* F. Discharge temps of your usual compressors are far greater than 150* so I would not use it to receive your compressors discharge W/O aftercooling. As far as the vacuum pump goes, what kind is it ? Do you have a model and serial number. Maybe I could sell it for you.

Steve,
I knew you would come through on this one, I almost just PM you directly with the info.

I didn't get the info off of the pump, I'll be back next week to pick it up. I'll PM you with the info then. It is a monster though.

Could this possibly be made to work as a compressor? (I know I am asking a lot, but I would love mcgiver something together)

I am suprised on the 150F, I wouldn't have expected that to be an issue, but I have never felt a the output of the pump, only the cold air expanding on the way out.

 

To get the degree symbol, hold down the ALT key and punch in 248 on the numeric keypad then release the ALT key. Makes == °

-Just my 2¢ lesson today

ALT 155 == ¢

 

You mean like this;

°F and ¢ ?

Awesome! One more reason my $15 FTE membership was worth it!

Now if I could just figure out a way to remember this!

Look at a the other cool symbols I found randomly holding down alt key and punching in numbers;

The Geek Patrol just broke down my front door and are now taking me into custody.

 

I think that would be true if you had a compressor on the same scale as the tank. The 3.5 hp is going to be very hard pressed to raise the temperature of that tank very much. It would be like trying to boil a pot of water over a paper match.

BTW, I have seen the effect of a 50 gal water heater used as an air tank. The pressure it let go at is unknown. It was outside of a residential garage. It blew an approximately 8' hole in the wall, ground to ceiling, and broke most of the rest of the wall studs off the footing, pushing the whole wall inward. It took out every window that looked directly at it, and blew down a section of nearby fence. It also left vertically through the rafters and sheathing above it, and some 2+" pine tree branches. It attained enough altitude to be seen 1/4 mile away over 100+ foot trees, before returning to lodge in the roof of another house 2 doors down. It's absolutely amazing the amount of energy stored up in an air tank.

The guy with the tank is criminally stupid. Not only did he build the thing in the first place, but it had no pressure switch, no relief, and he goes off and leaves it running. He "thought" the copper tube he had hooked it up with would burst if the pressure got too high.

Go for it. Be careful.

 

MZUGG,

You paint such a vivid picture of destruction and then tell me to go for it?

You might be crazier than me!
