Pinholes in compressor receiver

[Gas mark 5]

As per the title, I had just cleaned up and serviced by little broomwade compressor, and before starting it up I gave the tank a quick check, and found a couple of pinholes on the underside. I went over the bottom of the receiver with a ball pein hammer, and while the rest was solid, the tank dented in around the pinholes.

I'm all for keeping old stuff going, but at the same time I have a healthy respect for compressed gas. I assume this is caused by water sitting in the bottom of the tank that hasn't be drained, so presumably quite a large area will be in a similar condition. Is there anything at all I can do to safely revive this tank, or is it just not worth it?

I suspect I know the answer, but I've had difficulty in finding any suitable replacement on a student budget - I thought a propane / butane gas bottle would make a good cheap alternative, but they don't seem nearly available as I expected, they're all tied up in contracts?

Any suggestions anyone?

Thanks

You can't be looking in the right places for an old gas bottle, they are everywhere.

I've just tried ebay, that's where they're all lurking! I don't know why I didn't think to look there, sorry.

Are they a suitable replacement? I doubt my compressor will be able to struggle to much over 100psi, perhaps say 150 to be on the safe side. Are propane / butane tanks rated to significantly higher than that?

I ran a 47kg propane bottle tee'd into my old 100litre compressor for years at 150psi,

Put a wanted on here for a bottle and state your location which should get you one,
i certainly wouldn't chance that tank under pressure, probably best to punch a hole through where its corroded so others arent tempted to use it depending on where it ends up going.

That tanks scrap or at best a wood burning stove .

I've got a load where you from

Stick a wanted ad on Freecycle, I did this recently and got offered over 20 bottles in total from various sources, including some full and partially full bottles!

Canterbury during term-time, Somerset otherwise - both a bit of a trot from Durham unfortunately! Thanks for the offer though. I have potentially managed to source a butane bottle, but I know butane is stored at much lower pressures than propane - will butane bottles still be rated to high enough pressures?
If not I'll stick an ad on freecycle and see if anything turns up, or indeed here. Thanks for the advice all
