I've seen some white PVC pipe with crud like this but none where
the outside of the pipe "looked clean". Seems to me a very simple
inspection method would be to pass a "Tesla coil" leak detector
probe over the pipe or, even simpler yet, just move it around over
the top of a "standard TC" operating at low enough power that
streamers don't work along the pipe to the fingers holding it.
I tried a leak detector and it ignored the specks of stuff. But even
metal would probably look fairly isolated so maybe it would not
attract arcs still.
I worked at a plastic molding shop for a short time and they made
computer and light medical plastic parts. All kinds of odd things
got into the plastic as it was dumped from here to there. Of course,
"bugs" are just "what is left of something organic" in the final
product. I could guess that PVC sewer and drain pipe is not made
under the most pristine conditions. The strain out stuff that will
actually break the extruder or molds, but other than that I doubt if
they care. I very well remember that "people that care" we in very
short supply in that business! But it was 25 years ago so maybe it
has all changed ;-)
