Shop Question
Yes Old Timers, My search of knowlege has led me back to my roots.....the ZX-12R Zone. For only here can I trust the sage advice offered. Ahem....at my new job I have noticed that there are many places where copper pipe is used for compressed air systems. Has anyone ever used this setup before or know anything about it? I figure it must be type K pipe but haven't been able to verify that yet. Anyway, I would get my new shop up and running alot faster by sweating copper than threading black iron pipe. Help me please.

Most new shops I've seen use PVC pipe for running air lines. Much much cheaper than copper pipe, and is quite capable of withstanding 150 or so psi.

Even better. Primer and glue is easier than sweating copper. Thanks a heap, swft.

I have used copper pipe in the past for both industrial and home shops. The pipe used was nothing special, just picked up off of the shelf at home depot. The industrial shop where I installed the piping had the compressor cranked up to 175psi, and there was never a problem. Some of the piping in that system was 30+ years old and we never had any issues.
One question.....what is available for adapting from 3/4" PVC to 1/4" NPT for your air hoses and fittings? If there is a good option I will definitely consider PVC for my own home shop.

I was thinking of using copper in my house too but PVC seems like an easier option. I was wondering the same thing as Maxxer was.

I wouldn't recommend pvc in a high pressure situation!!! It's ok behind walls or above ceiling/buried in concrete, etc., but if it's in a exposed area, you're asking for trouble!! When pvc explodes, it shatters and sends out nice little splinters. I believe it is also illegal to use it,....at least in a public place. There's a plastic pipe on the market that does not splinter and is approved for use w/ high pressure air. I can't think of the name right off but it is thick walled and it's green .
I ended up going with galv. pipe 'cuz it's cheaper.

Just set up my son's shop/business with all copper air lines. Piece-o-cake to sweat in the junctions & fittings. PVC is waaaayyyy bad news and is not legal here. In the winter, any water in those lines will/can cause them to grenade. Been exposed to that..... And it scares the livin shit out of you.

We use standard copper pipe for all air lines in our manufacturing plant. Woundn't recommend plastic either as it will get brittle with age and can shatter. The copper would just bend or crack if dammaged somehow(easy to fix).

What kind of pressure? Note that I said I don't go over 150 psi

My 7 hp, 70 gallon tank is regulated at 160 psi to the lines. No problems noted.
