Ok, this seems like a dumb question and one with an easy answer but after
searching the web for several hours and reading numerous articles I am
unable to find it. What is the metal duct used for dust collection
systems?

Is it simply single walled stove pipe? If so, is it possible to buy it in
like 10' lengths. Any recommendations as to where to buy it?


Stove pipe is not designed to withstand any kind of pressure. Its too thin
to use for dust collection. Many many people are quite pleased to use S&D
(sewer and drain) PVC pipe for a home dust collection system. Its cheap,
easy to assemble and the fittings are readily available in many larger
Lowe's and Home Depot. Be sure you get S&D instead of sched 40 pipe. S&D
fittings are about 1/3 to 1/2 the cost of PVC pipe fittings.
