What material is the most cost effective for air lines?

I guess with good water seperator would eleminate the pooling issue.

lol wtf?! Ive had my pvc line blow out only once in the 12 years its been all together running and holding 190psi for weeks on end constant and it never exploded it just pulled out of a weak joint....you made it out like pvc is a deadly killer with compressed air in it!!! lmfao!!

PVC is fine like I said 12 years and running and only one problem seems legit to me.

I have met a few people that swear PVC used as an air line will with out a doubt kill some one eventually. I am would not go thay far but I can see the concerns. With where I plan to run my lines if they do explode I seriously doubt any one will get hurt.

well, you seem to be on a budget, so i think the best option would be using a soft line to run the air. then when you move, you can roll it up and take it with you.

**LonesomeTriZ** · 06-21-2010, 06:51 PM

That is one thing that appeals to me about using a soft line. Plus, if i want to hard line it later I always have a use for sfot air lines. So it will not go to waste.

whatever....lol come one louis I know good and damn well you really didnt need to get on here to ask about air lines if you want cheap you can run either pvc or goto a fleet truck center and get the DOT air line and fittings its cheap. But all this noise abotu pvc being so deadly is the biggest pile of crap ive ever heard in my life.. oh yea im sure their are a million cases of people getting brutaly killed by bad pvc but were they doing it correct? im sure some hilbilly used elmers and scedule 20 1 pvc and ran 200psi on it and it blew slaugtering his whole imbred family and now just like trikes are to blame that they kill people so do pvc now......

I was mostly looking for something I may not have heard of. I do not claim to know everyhting about everything. I did learn a lot about PVC though. I did not know there were different thicknesses. A little like that may have cause a serious issue down the road.

**big specht** · 06-22-2010, 08:25 AM

I plan on useing somthing like scedule 80 pvc in my shop we plan on making a 2'' halo around the shop then 1'' drops for more capasity(can't spell). I've seen pvc used and abused as air lines and never seen one fail

**LonesomeTriZ** · 06-22-2010, 08:57 AM

i have worked at shops that ran it out side in the weather and did not have problem.

PVC "can be" dangerous is the only point I was trying to get across. It's not suitable for air lines. There are as many success stories as failure stories with PVC. You guys can use a garden hose for all I care, he asked and I offered my best suggestion. I guess this one wasn't enough to sway anyone http://www.cnczone.com/forums/archiv...p/t-35978.html .

If I find the post that shows the carnage were the person said "Thank god no one was near It", I'll post it up and you guys can laugh at it, discredit it or shrug your shoulders.

That was the reason I chose not to use schedule 40 PVC.

When we used schedule 40 for a water source heat pump, half of them blew apart when we turned on the water. Back to FB Webb we went and they said the high pressure was just a fitting with a deeper shoulder to hold more glue.

I agree with DC....i have seen PVC potato cannons shatter, and PVC is EXTREMELY dangerous to use as a fireworks tube launcher. if you want a pvc-like line without the risk, get High-Density PolyEthelene (HDPE) pipe. it doesnt shatter.

**LonesomeTriZ** · 06-23-2010, 10:31 AM

I have not heard of HDPE. I would like ot learn more about it. There is a chance my finacial concerns might go away soon. Well, not enitrely but at least soften up a bit. If so I might go with some better material.

and that has alot to do with 120psi compressed air in povc as well......I see that the simialarities are stagering....so if I put compressed air into a 2 litter bottle and it explodes its about as unsafe if I put compressed air and a unpinned granade in a 2 littre bottle? its still a 2 littre bottle......

That was funny^^^^^^^^^^^^

I'd say "I'm done with this thread", but I'm posting so obviously I'm not, but I will be after this post:

Use whatever you want, whatever is cheapest. Maybe you can go to the junkyard and get some used pipe. Then use some truck inner tubes and shove them in something so they won't blow up when used for a holding tank.- Maybe some 2' sewage pipe or something to act as a holding tank.

And screw respirators for paint, just wear a dusk mask; If you feel overcome with fumes, just get some fresh air and then get right back at it!

Have a ball.....
