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?
