I think I might opt for securing it with twine (a bit of Maxwell's idea) on the top and bottom and inserting some dowels inside along the length of it (if needed). Just make sure to get a piece of bamboo with enough thickness to hold the dowels. A good Dremel for drilling the holes would help too. You may need to glue one end of the dowel into the bamboo, but the piece would still be easy to take apart if necessary. And aesthetically, I might lean a few smaller pieces of bamboo on/around it so (as manu_pty mentioned) it's more of an arrangement. Of course, this is all dependent on the location of the pipe.
