I just bought a 100-foot air line from Harbor Freight and snaked that through the walls from the garage to the basement shop. I added a moisture trap and a regulator at the basement end. The compressor runs at 125 psi and I can cut down the pressure in the shop to anything I need for pin nailers, etc. This is really convenient and probably cost less and took less effort than any kind of plumbing.
That being said, a friend used ordinary CPVC pipe which is rated at 200 psi..

And he may luck out and move before it breaks, or he may luck out and
there not be anybody near it when it breaks. You might find a couple

Note that the second one is by a major manufacturer of PVC
pipe--_they_ are telling you to _not_ buy their product for this
purpose.

Yes, there are more likely ways to get hurt in the shop. That does
not justify using something that is known to be a hazard when there
are well established safe alternatives.

How instructive is a video that shows that they couldn't get the PVC to
shatter until they battered it numerous times with a weight of an unspecified
amount from a height of 12' and then *froze* the frigging thing?

For all we know, it would have shattered at 0 PSI after taking all that
abuse and then being frozen. Heck, for all we know, it would have shattered
the *first time* at 0 PSI once it was frozen. Bad example.

How instructive is a video of some guy who says nothing more than "Don't
do it" without anything to back up his words other than some videos of PVC
bursting after being subjected to...oh, wait...we have absolutely no idea
what it was subjected to. Bad example.

Nothing I said indicated that I plan to use PVC for high pressure air or that I
suggest anybody should.

There's a big difference between pointing out bad examples vs. disagreeing that
with the main concept. Just because those videos do a terrible job of explaining
why you shouldn't use PVC with air doesn't mean that you should.

For example, if that second video had given any indication of what PSI caused the
failures they would be perfect. Since they don't, we have no idea if the test resembled
real world conditions or were just done for effect.

In other words, they weren't very "instructive" other than to proof that you can indeed cause
PVC to shatter while under pressure. Freezing the pipe apparently helps too..

Here you go...

How about I post this video with the warning "Never, ever, ever fill
your tires at a gas station!". I'll make sure I label it as "instructive".

https://www.youtube.com/watch?v=WeKA0eImhWQ

I'm pretty sure that you, being the intelligent gent that you are, would
be one of the first to point out that we know very little about the root
cause of that explosion. Our *experience* tells us that the situation is
out of the ordinary, therefore we wouldn't consider the video to be
"instructive" as it relates to the "Never, ever, ever" warning given.

Regarding the PVC video linked to above, we don't know if they tested that
PVC with 60 PSI or 600 PSI. To be considered "instructive" (and that *word*
is the only thing that I'm talking about) the video needs to tell us
something about the test conditions.

To be clear, I am *not* recommending or even suggesting that PVC be used
for air under any conditions. My only point is whether or not those videos
can be considered "instructive" in the context used.

Oregon OSHA states

Plastic pipe used for compressed air service must be designed for such
service by the
manufacturer. Examples of such pipe include high-density polyethylene
(HDPE) and
Acrylonitrile Butadiene Styrene (ABS). Compressed air piping systems
that use plastic
pipe must also be “project specific” – i.e., suited for a particular
application or project –
and installed by a competent person.
Polyvinyl chloride (PVC) pipe must not be used in
compressed air systems unless it is buried or encased.
PVC pipes are unsafe when
they’re used for compressed
air service because they can
shatter or explode under
pressure or from an external
force. Sunlight (the UV
component) can also reduce
the impact resistance of PVC
pipe.

I tend to think of ABS and PVC pipe as being the same. My usage of either pipe is with plumbing. Hard to believe ABS is compressed air compliant but PVC is not. Seems to me both would not be compliant.

All true, and had *any* of that been included in the videos, then they could
have been considered "instructive".

You do understand that my only issue is with the use of the "instructive"
descriptor, right? Neither of those videos are "instructive" in my opinion.

Sensational? Sure. Condescending? The second one, yep. Instructive? Not
so much.

ABS fails in a less spectacular fashion - less fragmentation.

PVC is also a lot nastierto glue as well, as it requires primer AND
cement, where ABS only needs cement.

In other words, they weren't very "instructive" other than to proof that you can indeed cause
PVC to shatter while under pressure. Freezing the pipe apparently helps too.

Except that I don't want to be anywhere around it when it does. That's
good enough for me. You welcome to risk your life foolishly.

What is it that prevents you from understanding what I am saying?

I tend to think of ABS and PVC pipe as being the same. My usage of either pipe is with plumbing. Hard to believe ABS is compressed air compliant but PVC is not. Seems to me both would not be compliant.

The chemistries of ABS and PVC are rather different. Among other
things ABS is sufficiently impact resistant than at one time it was
used for motorcycle and racing helmets.

OK. I think of ABS as plumbing waste pipes. Black sewer pipe. And PVC as plumbing water pipes. The white/yellow/tan water lines. Pretty sure I have used both in plumbing. Both seem too hard and brittle for airlines.

As with everything, the details matter. PVC pipe in a pipe chase or
protected by an enclosure is perfectly fine for compressed air so long
as the PSI limitations of the pipe are honored.

PVC pipe in a location where it is subject to abuse, bad idea.

I just bought a 100-foot air line from Harbor Freight and snaked that through the walls from the garage to the basement shop. I added a moisture trap and a regulator at the basement end.

That being said, a friend used ordinary CPVC pipe which is rated at 200 psi.

And he may luck out and move before it breaks, or he may luck out and
there not be anybody near it when it breaks. You might find a couple
of videos instructive:

How instructive is a video that shows that they couldn't get the PVC to
shatter until they battered it numerous times with a weight of an unspecified
amount from a height of 12' and then *froze* the frigging thing?

For all we know, it would have shattered at 0 PSI after taking all that
abuse and then being frozen. Heck, for all we know, it would have shattered
the *first time* at 0 PSI once it was frozen. Bad example.

It may have shattered without pressure but it wouldn't have exploded,
throwing shrapnel. No thanks.

How instructive is a video of some guy who says nothing more than "Don't
do it" without anything to back up his words other than some videos of PVC
bursting after being subjected to...oh, wait...we have absolutely no idea
what it was subjected to. Bad example.

No, not at all but you're welcome to experiment with your life.

Nothing I said indicated that I plan to use PVC for high pressure air or that I
suggest anybody should.

That *was* the subject.

There's a big difference between pointing out bad examples vs. disagreeing that
with the main concept. Just because those videos do a terrible job of explaining
why you shouldn't use PVC with air doesn't mean that you should.

For example, if that second video had given any indication of what PSI caused the
failures they would be perfect. Since they don't, we have no idea if the test resembled
real world conditions or were just done for effect.

You take all the unnecessary risk you want. I'll do otherwise.
