I have ran miles of grooved pipe, 2" to 12", copper,black iron, galv,stainless, and plastic. It is fast and easy once you have thousands of dollars of equipment purchased, lol.
Personally I like type L copper for air lines, fast simple, one time install, and easy to modify when you need another connection at a later date.

I'll have to run out to the garage tonight and check out the outlet, Iím hoping youíre right about the reducer, I've heard the same thing about galvanized. The drain valve sticks out just enough for it to not be a problem; Iíve heard of other people having issues with it so Iím wondering if it was something that were corrected through the years. Thanks for the input

The copper will transfer heat faster than pipe. I have 50' of black iron threaded across my ceiling for cooling with 3 drops to drain off water. I had read the galvanized coating was thin inside the pipe and people had problems with it flaking off and clogging fittings so I used the black. It's been in there 8 years and no rust issues...
If the drain valve is still under the tank, buy a street elbow and run it out to daylight. MUCH easier to turn the handle out where you can get at it.

the dryer is only on one outlet, for painting..
water seperating filters at the other 3 ..

|K72Nova||Sounds like I'll have to give Quincy a call and see if there is a way for me to hook up a 3/4 outlet.|

forgetting one thing..
it really makes no sense to run a larger line then the fitting on the compressor is. if u look for more storage of air then a lg line is ok.. IF u want flow... then make sure the fitting from the compressor is the largest it will take. the smallest part of that line is an "orfice" and u can not flow more air then that part will allow. and thats the ID of any part on that line.

|K72Nova||There are actually 3 types of copper, and even the lowest grade (Type M) has a working pressure of 326 PSI @ 250F, even if that was the stuff I was going to use it would work. The question was never the rating, durability or strength of the copper but the heat transfer comparison to black iron pipe. My original intent was to use black iron; however after talking with a friend of mine about what he has plumbed shops around here locally with and pricing out the final system with copper being the less expensive solution, I chose copper.|

price it again. there are 2 types of copper pipe..
tell them you are running 150psi in it..
not 10psi cold water

|K72Nova||Copper would be cheaper for me based on current prices at my local lowes, $.26 cheaper per 10' length. I also have a plumber friend who is going to give me fittings he has laying around from old jobs. Another pricing issue with black pipe is that a 6' pipe costs $1.95 more than a 10' pipe, I'm not too sure how much rental cost of a pipe threader is.. I could have lowes cut down 10' pipes to exactly what I need but the convenience of being able to easily cut copper to length on site is a plus.|

the roll of romex I bought 5 years ago was 39.00
the other day it was 119.oo for the same roll of copper..

how many tools ?
Size would depend on how many tools will be running at once, If you do it your self labor cost wouldn't matter. I took over as facilities manager at a factory and they had 1/2 copper main lines and the first day I could hear the air screwdrivers slow down when 3 or 4 people were working the same time. I always over size , conduit and plumbing systems, cooling water, Air, etc. you need some reserve capacity, If you have to rent a power threader , or make changes later copper is easier,

|no-scar-no-story||Another choice is aluminum. The fittings are a little expensive, but for ease of installation and corrosion resistance, it can't be beat. Transair is the brand I used in a couple of commercial buildings.|

|K72Nova||Lots of suggestions for black pipe, what if the cost was the same or a little less for the 3/4 copper? I was under the impression that copper transferred the heat just as well as iron pipe to deal with condensation? As for people stealing it, I'm not too worried about that, I have things in my shop that would be worth much more to someone that they could get out faster and more easily; also I have security in place to prevent that sort of thing..
