?? For those with onboard air tanks

[Dkevdog]

OK- I'm finally getting around to getting everything installed complete for my blowjax compressor and tank. I did not get the tank from AIM, I had one I ordered before the compressor. It is a Firestone 3 gal hot dog type tank, and is supposedly coated inside to prevent corrosion. The one thing I didn't notice when I got the tank is that it only has fittings on each end, which makes a draincock impossible to install. I know that condensation is generally a problem in compressed air systems, is this gonna be a problem?? And if it is, is there a way to safely weld a fitting into the bottom of the tank for this or should I get a different tank??

You will deffinately accumulate some water in the tank.





I would be very careful here. While it is not a problem to weld in a fitting, keep in mind that this is a pressure vessel, and the welding needs to be done by someone qualified to do such work. If it were mine, I would look for a tank with a fitting in the bottom. A catastrophic failure of the tank at 100-150 psi is not something you want to witness from up close.

Lug-nut is right. There are pages and pages of ASME specs on pressure vessels. EVERY weld on a pressure must be magnafluxed and x-rayed to make sure there are no flaws in it. you might be able to attach a tube to one end that would reach to the bottom of the tank inside. add your drain cock to the other end of the tube and the air will push the water out of the tube. Good luck!

I have an On-Board-Air system that I have yet to install.



I talked t Bad Kilby about the drain valces and he said he uses a plug.



The valves usually leak and require a pair of pliers to open and close anyway. . if you have to fetch a tool, get a wrench.



any welding shop can handle work on an air tank. they rarely see over 175 psi... just test it for leaks.



I've seen some bumpers that were air tanks. . pretty neat lookin.
