Advice On Plumbing in Compressed Air Line

   / Advice On Plumbing in Compressed Air Line #2  
It is a pretty common system in industry that is used for piping compressed air and vacuum in automation equipment. Typically small stuff like up to 1/4" hoses, but the principle is the same. Often polyurethane tube, but can be Polyethylene or nylon even. The fittings are all push connect and seal with o-rings. Very easy and pretty reliable. Otherwise copper or iron is the way to go. NEVER use PVC pipe for compressed air as it is prone to fail from an impact or from oil/UV exposure and will send shrapnel everywhere. People have died from this, so avoid it.

I use copper for my air lines. As the stig said...never use PVC for compressed air service. If you don't think PVC will shatter, take a 12" piece of 3/4" or 1" and throw it against a concrete wall as hard as you can, then go look for the pieces.

the link you noted, i am a tad un=easy about when they showed diagram of were all the lines are. and not showing any sort of "drip legs" for water condensation within the pipes. an air dryer/cooler to remove water before it goes into your pipe system is advised. and the drip legs, that you can easily remove a end cap and let water out. ((when there is no pressure in system)) is advised.

air tools that use the most CFM of air, at the highest PSI. will require the most air. and you should size air line pipes/hose based on that. other words if cash allows. go for 1" main lines. and then reduce down at the quick connect box. were a short hose and air tool would connect.

you might want to run a secondary air line pipe. and hook a oiler up, before air goes into second pipe run. for tools that need regular oiling. and then have the other pipe run for air gun / paint sprayers, tire inflaters and like.

make sure what ever you use, is UV resistant. and try to keep out of the sun.

you may want to run some metal pipe off of air compressor, oilers, heaters, coolers, regulator, and like. before air goes into the distribution air piping. the metal. can with stand higher heat most likely. that may get transferred from the various things.

vibrations will be a killer for plastic hose / pipe. and you will need to take extra caution in how you run it, and how you fasten the hose to walls and ceilings or what you run hose over.

pending on setup, it might be worth while to run a "loop" clear around building and dropping down were needed for air connection vs running a different hose and teeing off were ever.

Those are nice systems...
I would do like boggen suggested and run a main trunk line down the middle of my shop and then t off drops anywhere I though that I may need them...
Air drops are sorta like electrical outlets...
You can never have too many...

We dont use that particular brand but we do use a lot of the push-to-connect stuff. It is really reliable and quite simple. No threading and cutting pipe, and no sweating fittings as with copper.

For tubing, there is a lot of different stuff as dstig1 mentioned. I dont know what is what off the top of my head, but they can be had in many colors, and can be had semi-ridgid or flexible.

Copper, no down side on safety, easy to install and move later if need be and will never leak. I've had my compressor on for the last fifteen years and it still goes days with cycling. As for oilers, after a while you'll have OIL EVERYWHERE. Pull the trigger, put just 6 or 8 drops into the air nipple, hold it nipple up and plug in the air, and, you're set for all day. Use good air tool or synthetic oil. Oh, and only use RUBBER hoses, they don't get stiff when cold and always lay flat.

Copper is expensive and being easy to install is subjective. While you or I may think it is easy, it certainly isnt the easy of the mentioned options thus far.
