Compressed Air Line Question

[Deere Dude]

I am waiting for someone to make a PVC test and video it.

Take a 1" PVC sch 40 pipe with a cap on on end and an air fitting on the other end. Then smack the cap with a hammer and see what happens. Just curious.

Important to note, this was brand new pipe. Yes, it didn't break while at normal temps, but it did shatter when simply frozen in a freezer. Times that by a few years of use with pressure cycling, degradation, freezing/thawing, etc, and you have seriously reduced the strength of the pipe to a point where it either goes by itself, or doesn't take much impact at all.

Trying to reinvent the wheel, would be more productive.

The danger has already been established. The internet is full of reports of people being injured by PVC pipe air lines.

And, I have seen it first hand.

There is a lot more to it, than just dropping an object on it.

As well as temperature, you have pressure, age, vibration, contamination, UV, improperly glued joints, and previously undetected damage. Separately, and combined, these make for lots of different levels of risk.

A friend of mine owned/ran a auto repair shop, when he bought the bld. the air was plumbed with PVC... One day one of his mechanics threw something up on the bench and it hit the pipe, nothing happened, so they never gave it another thought.

About a week later (when no one was near it) that pipe blew up and it exploded right where it was hit earlier!

He tore all that pipe out right then and replaced with blk. steel pipe...as it made a believer out of him! lol

Very cool and informative video. Usually, what's the worst that happens when a (shop) air line breaks. Some unexpected noise and an investigation as to what is going on.

It was a real bummer when I connected my 100-120PSI shop air to a 2 liter soft drink container and it didn't bust. It struck me, that so much plastic consumer garbage we buy is just that, and yet these disposable containers are quite impressive.

A little off topic but related.

Today I brought my small portable air compressor over to a friends place to air up some flat trailer tires on a trailer that has not moved in many years sitting out in the field.

Decided to go 30 psi all around... the first three aired up nicely and all was good.

Went to air up the last one and stopped when it got to 30... a moment after I pulled the hose from the stem I heard a ripping noise and KaBoom... tire exploded sending pieces everywhere... my friend was up at the tongue about 10 feet away and got hit on the cheek with flying tire and my right ear still rings...

Amazing just how much force/energy is in 30 psi!
