Maybe I'm wrong but I read the list price for a 6" diameter pipe as $22.80
per foot. WOW!

I saw a portable air conditioner for lab environmental testing at work
today, and the 6" air ducts in and out of it were made of a
"ribbon-lock" PVC that I hadn't seen previously.  It was made such that
unlike corrugated aluminum ducts, it absolutely won't dent from minor
accidents, unless you deliberately jumped on it.  The maker of the A/C
unit, Topaz, said I had to buy it from them, so I started Googling.  I
found something very similar (maybe the same?) called Pliaduct.  You can
see it at http://www.ducting.com/Pliaduct.html.  It is available in
diameters from 2"-12", standard lengths 25' for 2"-6", and 10' for
8"-12".  The price for a 6"x25' length is $22.80.  The really neat thing
is that the two ends will seamlessly mate with no tape or adapters
needed, and you can series-connect multiple lengths!

Obviously one must cover a PVC toroid with aluminum tape to make it
conductive, but the surface is flatter with less pronounced ridges than
AL duct, so it will look nicer and probably be less prone to corona.  As
I don't actually need another toroid I didn't research the cost of
shipping such a thing to me - most of the vendors I saw seemed to be on
the West Coast - but I'll leave that to someone who needs one.  Any
follow-up from anyone trying this would be much appreciated!
