running it in the garage as air lines off the compressor. It said it has a 600 PSI and I just bought a new compressor and system for paint. I have a few friends that are running it and they like it. what are you guys running.
 
I have always read that it can be unsafe. I have heard of cases where it explodes and sends shards of pipe flying every where, right here on the board as a matter of fact.

They do make line specifically for that purpose.
 
The consensus is it ain't a good idea.
 
PLEASE don't use PVC. Its outlawed under OSHA for a good reason. I suspect that in very cold, ETC, it loses strength. It can shatter and produce what amounts to shrapnel.

Copper or black iron Pitch it just like in plumbing drains.......1/4" / ft and put traps in here and there
 
NO NO NO!!!!!!! DO NOT use PVC WITH compressed are or ANY gas. if it goes bad it doesnt just get leak like iron pipe. i splits the entire length. this is because PVC will NOT handle a shock load. like compressed gasses. what 67dare273 said + 4
 
I used black pipe, and besides the traps, I added a number of shut off valves.
Also, be sure to use teflon tape or pipe dope on all connections.
 
I have been using pvc pipe for air in my garage for over 10 years now but I do keep my pressure at 125.

PVC pipe manufacturers state in their literature "not to be used for compressed air". Check out manufacturers like IPEX, Spears, Charlotte Plastics, GF. When it fails it shatters like glass fragments.
 
What am I running? NOT PVC.... don't do it... and warn your friends.... please! And, it is not very good for exhausts either....
 
Found this on another forum Bill:

Having witnessed a PVC failure first hand in a shop I worked in, I will not use it for air line. The shop I worked in had added some square footage and ran 2” Schd 40 PVC as a temp. air line. The line failed at a coupling, a fellow working at a bench received a laceration on the top of his of his skull about 6 inches long that went to the bone. Bled like a stuck hog – the rest of the pieces took out two eight foot light fixtures, not just knocking them down but breaking them beyond use. The only thing the investigation could come up with for the failure was an unseen weak spot in the pipe. This pipe did not “come apart” it exploded. All that damage at 100 PSI,http://viglink.pgpartner.com/rd.php...eativeASIN=B00F6AVCWO&st=feed&mt=~~~~~~~~n~~~ I might use it in a pinch, but not for long and not as a main run.

"here we go again"...

I wouldn't have wasted the time it took to type that. If I had known you went through it before, I wouldn't have asked your opinion on the subject. I thought that was what this website was for. To get help with projects of all kinds. I have read about PVC explosions and injuries but some people on the internet like to just talk so I figured I would just ask here. I guess I will stay with black pipe or the galvanize pipe. However the Rapidair or the PEX sounds good too. That is the answer I was looking for. Ideas, not " here we go again". Thanks for the info.
 
I ran 1" schd 80 pvc overhead, out of harms way. It is expensive but it is light weight. All the drops are 1/2" iron.

if you do, use sch. 80 for the pipe and fittings, keep them out of direct sunlight, keep pressure off when not using, keep the pressure 100 or below. been using it for yrs. , no problem. use a flex connection on the compressor-" no movement on the lines!--bob
 
yeah, I am going to put an insulator off the compressor. I may go with the PEX or the rapid air from Northern tool. I am going to do some checking later today and see which way I want to go here and how long it will take to get the kit to me. I need to get this new compressor swapped out asap. I am picking up another car later this week.

I have had PVC on my system probably for close to ten years. I don't use it that often, but after reading all the info on it from here, I shudder every time I bust it off........especially since I plumbed my big compressor in at 175 PSI. As soon as I can afford some black iron pipe, that's what's goin in.

I like your setup. Quality equipment is the way to go.
I haven't run any PVC or black pipe on mine yet. Hose connections right at the tank. The good year hoses are going on nearly 15 years now. I thought I would get another length of hose to reach outside and the farm store stopped carrying Goodyear. Dont waist your money on offshore brand hose. Didn't even make it 6 months.
 
I keep my line pressure down and been running PVC for many years now. I don't leave my compressor on when not in use. Guess I am lucky. Now I will worry.
 
The maxair setup available at norther tool and probably others, works well. We use it repeatedly for new set ups in the company I work for. Extruded plastic inside and out of aluminum tubing. Easy to install and a kit that would be good for home shop use runs 200 plus tax here in TN.
 
hey duster, been studying on that same compressor for awhile now. read about as many bad reviews as good, but you know how that can be. let us know how it holds up. it looks like a good unit. dave.
