    In our town, the masonry supply store is the best options. They have selection on size, and best price.

    Look under 'masonry supply' in your phone book...

    Good luck with your repair!

      Flue tile is cheap, but it's heavy. If you're in a hot climate, there may not be much call for flue tile, since it's used to line chimneys. As Jed said, check with the brick yards: the 8" square is the most common size, and the one you want. It may not be practical to ship.

      There's been some talk of substituting 8" cast iron waste pipe for the clay liner. It may be more readily available.

          The stainless one i used didn't hold up
          What type of stainless did you use, 304 or 316?
          Also how old was it and what conditions was it used in?
          Stainless should last you 10 to 20 years in a flue. I'm hoping to get 5-8 years from the galvanised steel that I am using and then replace it with the more expensive and harder to find stuff. The ceramic or enameled (porcelain and not the enamel paint though) coated steel flue is also an option.

          Prevention is better than cure, - do it right the first time!

            No, not even close. Single wall stove pipe will rot out in a season or two.

                  Chimneys get very hot, particularly down at the bottom. Concrete may crack and spall, and refractory cement is expensive.

                  I can't believe that you can't get flue tile in a big city.

                  is a place in NO that brags about a full line of masonry fireplace accesories on their homepage. And that's just the first listing i clicked on. There are dozens of others.
