Orange pipe? what is it made of? Answered

I recently found an orange PVC pipe and cleaned it out. I was hoping to use it for the Vandegraaff I am making, but it isn't made of PVC, and barely generates any static electricity. I don't know much else about it, only that I am trying to resist the temptation to call it a carrot.

I might have seen some of that orange pipe.

I recall, a few years back, someone was burying plastic, orange, pipe-like stuff, about two inches in diameter, along the side of a road near where I live. I think I even saw big spools of it, on the backs of trucks, waiting to be buried in the ground.

I think it was a local telecommunications company that was burying this stuff, and I remember I went to inspect one of the ends sticking out of the ground, after the trucks and workers had disappeared, or gone home.

Naively, I was hoping this was good omen, meaning the possibility of faster Internet was soon to be arriving in my neighborhood.

The funny thing was, they had buried this orange conduit empty. Like if it was intended to contain wires, or glass fibers, they must have been planning to pull it through those orange conduits, at a later date.

Regarding the question of what kind of plastic your orange pipe is...

If it is unlabeled, and you lack any other clues, there is sort of series of simple tests, (e.g. Does a soldering iron melt it? Does it float or sink in water? When it burns, what does the flame look like? When it burns, what odor does it make?)

There is a flow chart for this, and I saved a copy of it here:

And I think the last time I tried to share this flowchart with someone, in a forum topic, was here:

Hopefully, the link is working now.

The orange PVC pipes are used for electrical wiring in buildings and under ground.
They are more flame retardent and meant to clearly indicate that live wires are inside.
Quite often though they meant to only be used for fire control and alarm related wiring while the grey PVC pipes are for all other wiring.

Downside of being orange is having a differnt PVC composition - resulting is way less static problems as these can interfere with the sensitive equippment that the wires inside are connected to.
Sorry to say but they will be almost useless for your needs :(
