compressed air piping

[FredK]

Copper is super expensive these days. I think I saw ~$50 for 8ft of 3/4" ID, and it was either type L or M copper pipe.

[Rigmaster]

Yeah, scrap copper is like $3-4 per lb, so thieves have been stealing it from anywhere they can find it- construction sites, work trucks, power lines, etc.

No, PVC has the tendency to get brittle, especially when exposed to the sun. As it gets brittle, when there is a shock to the system, it will explode, sending PVC splinters all over the place. Should one of these splinters hit flesh after being explosively ejected at 135 to 175 psi, you can expect a visit to the ER.

agreed.. do you route your air lines outside?

route them on the inside. they will pick up less condensation.

Over here they cut off the pipes in public bathrooms, they have to build a security box around all the piping now :roll:

Its like anything else dude. you can do it a few different ways. if youre airing up tires it aint a big thing but if youre painting cars and caring for expensive air tools it pays to do it right and have drains.

hey, there were a couple of people here that thought pvc is ok for compressed air. the fact that they learned it's not is justification enough for this thread.
you don't sound like a true gearhead. talking about compressed air and garage shit is fun.

its not just air, its air a 90+psi if you put that much pressure in shit piping you have a big fuckin problem

This is a good point. Gear heads enjoy garage talk reguardless :P

agreed.. so what is the harm in using pvc inside?

[Rigmaster]

It blows up. UV rays are not the only thing that can weaken it.

Look, I'm a cheap MOFO, but even I would not use PVC for air lines, it's just not worth it.

Yea, not just outside....they are weak for handling that type of pressure.

Do it right, or don't do it at all.

ok, i have set up shop air for my dads (insert large unknown sq ft) shop on new machines that we got....had to use a man-lift for the 17 ft ceiling....also note that i have been around porsche's (race cars/street cars) since i was born...trust me im actually more of a gearhead than most of the "r3vers" here
