Don't think so.
Wrought Steel Pipes - Bursting Pressure

Black pipe has been used for air line for decades. I would use it over PVC for sure. I've seen PVC shatter under pressure. makes good shrapnel.

Totally agree with you about PVC.Even the 40 PVC stuff I would never use.Copper is so darn expensive.I am pluming in about about 100' foot of hard pipe for both sides of the shop.It is going into a pole bar/shop that I rented awhile ago. and will be left behind once I leave.Thing is weither it be extension cords or air lines,I believe to have the shortest lines to use to help not create a hard to work in area.Not a tangled mess on the floor.I am going to add on say 8' sections at over time with each section having a "T" for a outlet.The compressor is a over 10 yr old I/R two stage cast iron that was one that was still built in the U.S.I runs really good and is on a 60 gallon tank.I am going to run it with the pressure switch on at 100lbs-off at 150lbs.The I/R tech I talked to said it was one of the last really good built units after I gave him the model number of 2340 and a serial number.
