running compressed air for production area
running compressed air for production area
(OP)
My question is on a topic I don't normally deal with:
We are running some compressed air lines in a production area to supply air tools.
For those that do this on a regular basis, any advice or known pitfalls would be helpful to know. In my mind sizing the compressor should be fairly simple based on the number of tools and requirements, psig and CFM. Although again for you guys that do this all the time let me know what I forgot.
Also I am concerned about any OSHA or other regulations I may not be aware of. This is being done in the USA. Are there any requirements for safety values in a compressed air system other than on the tank? Any certain pipe material requirements, etc.
Thanks

Smaller pipe sizes are often done in copper , with the price of copper what it is today, epoxy coated aluminum pipe is a good alternative, here is a link to one manufacturer.

They also have pre assembled end fittings.

I vaguely remember that Ingersoll-Rand might have had a system to go along with their compressors. I recommend you look into something like that.

Page 14 of the document Bud recommended says "A loop system is generally recommended, with all piping sloped to accessible drop legs and drain points." I have heard the recommendation for a loop before, but I'm not sure why. I suspect it eliminates problems with dead zones and moisture, but it could also do with minimizing pressure drop because air would have two routes.

Try and create a ring main, that is do not have a blind end to the pipe runs.
Take discharge points off the top of the main line, moisture drains off bottom of main line,
slope main line away from compressor infeed point to drain points
Blow moisture traps drains off regularly or have auto moisture traps
Size the compressor with a decent safety factor for future usage
Good maintenance, correct air leaks if any as they occur.

We fitted out our new workshop and renewed all the old metal airlines in our old factory with John Guest Plastic tubing and Speedfit joints and fittings eight years ago. It all came on line without a single leak and has remained so to date. It works fine on vacuum or water too and all you need is a hacksaw and something to deburr the cut. Joints just push fit by hand and can be dismantled just as easily.

WHAT A NIGHTMARE. Finally fitted all tools with same fittings and solved all kinds of problems.

One thing nobody else has mentioned yet.
Unless you are in an area of the country where the relative humidity is very low, I would recommend a refrigerated air dryer, if you can afford it.
On days where the relative humidity is high and you have a greater than normal group using air, the compressor tank will get hot and instead of condensing moisture out of the air will dump it down the line where it will then condense out in your air tools.

At the drops most people I see put in double block valves with the top one being always open and the one on bottom being the valve you work.
If it is a large distribution header, I would put block valves in at the main branches also.
