It's not cheaper.? For example, right now 3/4" black pipe is?~20% more expensive than copper at Home Depot.?
It can be much, much more work to reconfigure than copper, though it depends on exactly what you're reconfiguring.? If you want to place a tee in the middle of a section of copper, you can do that in 5 minutes with slip fittings, or maybe 10 minutes with solder.? It's nowhere near as easy with threaded pipe.? ?

I worked in a production about 20 years ago and seem to remember they used black pipe for the air lines, which would be cheaper than copper and easier to reconfigure and wouldn¡¯t require solder.

Thanks, Gerald I used type L copper piping/fittings with 50/50 solder which will flow easily with propane torch. ? Silver solder is for drinking water applications and requires higher heat like Mapp gas.? Like Glen, I too like soldering - Heathkits when young got me in the habit. ? ?If you don¡¯t have a dryer at the compressor end, design your system with the expectation that water will condense in long lines and needs some manner to get out other than spraying into your equipment inlets.??If your main supply line throughout the shop is long and is high up, take the drops off vertically, then through a 180 and down - that keeps a lot of the water from condensation out of the drops. ? I also put condensation water dump ball valves at each end of the main supply and at the bottom of each drop. ? Examples below:

Hello,?
I'm in the same boat, getting ready to run air lines in a new shop,? I'm leaning towards copper,? what thickness/type did you all use?? Is type M too thin? Did you use silver solder or soft solder? Thanks in advance for your input.?

Mark Foster? For once, I¡¯m in complete alignment with John on this topic. I¡¯ve put copper in all my shops and wouldn¡¯t use anything else.? David Best - via mobile phone? ? ?Joe I used commercial grade copper, reasonable price for good tube and fittings. 3/4" with 1/2" drops. Combination of solder and Shark bites joints. Honestly black pipe or Aluminum weren't even considerations.?

I will be running airlines in the new shop soon.? I had been assuming I'd use Rapid Air.? If I do use that, would you do the hard lines or the roll. With the roll it looks like you need a straightener.? Or should I do copper? I don't use a ton of air.? I have an old Quincy 60 gallon with a 325 pump. I set it up with a 3HP motor so it runs slow.? I could change to a 5HP and double the speed to like 900 RPM.? I was thinking 3/4" lines would be fine.? I will use my current hose reel and add a couple more and a couple of machines need air. Advice welcome. PS, ordered all the Nordfab and the local licensed seller was cheapest.? Cheaper than Griz, etc.
