Compressor auxiliary receiver tank

[topbobster]

Hi everyone, Would the tank shown on this eBay listing be ok to use as an air compressor auxiliary tank, it will be stored outside under cover?

So what would a welder need to do to a gas bottle, what fittings would need to be put on it so could be used with the tank on the compressor, how to rig it up with the compressor?
Cheers.

It'd need some form of water drain on the base. Or turn it upside down and put a tee into the valve thread, or just into the valve. Part are easily available.

Getting rid of the stenching agent is the tedious bit.

I took the valve out of mine, washed it with fresh water a good few times, rolled it about and left upside down. Then cleaned with degreaser, rinsed, then swirled some bleach in, washed with water then added bicarb soda and three dishwasher tablets, let soak for a coup!e of days, then rinsed, swirled in more bleach, rinsed again and let soak with water and there was no smell. Bleach does seem to get rid of the smell in propane tanks but you need to wash the bleach out well as well.

I then drilled out two holes, flushed it with compressed air before tig welding on two threaded bosses. I went OTT but I wanted to ensure it was safe to weld but also didn't want my air smelling.

OK thanks for that. I was reading that compressor receiver tanks have an anti rust coating on the inside. Do you think that is a consideration, somehow putting an anti rust coating into the gas tank? Perhaps a bit like the old wax oil injector on my old Beetle? Or no need to bother?Any chance of photos of your gas tank?

What are you using the air for? If it's just for tooling then yeah you could coat with cavity wax. Main thing is to drain it regularly and keep it dry. There are photos in here of mine, if you search and use my user name you'll find them.

See my post #11 here, pretty much what you want to do but for a different purpose, but the principal is the same - and if I could do it, anyone can...

the tank wont need coating a gas bottle is thicker than a proper air tank . they all go rusty unless your comp pump is chucking oil out

Etching glass, carving into glass, etching is around 30-40PSI another technique shading can go as low as2/3PSI. I'll do a search, cheers.

OK I did a Google image search, saw. some tanks bigger than 47Kg but all seemed to be in US. Assume can connect 2 gas bottles in series?

After each use I'm opening the drain valve and leaving it open until the next use.
