How is the copper joined together? If it is soldered, then it at the earliest it would be a historic trade item. If it is just rolled, then it could be earlier but I'm not sure rolled would work for a pipe unless the edge is really folded over and sealed. Use a magnifying glass and look at the seam.
Maybe it is part of an old shine still, but it almost looks too well made for that. There is kind of the romantic notion of ornate copper stills pumping out bourbon in mason jars, but most of the stills were put together from junk and used old rubber tubes or strait plumbing pipe instead of relatively carefully crafted pieces and the shine comes in an old Tide Bleach bottle or a Mt. Dew bottle if the shiner has a sense of history.
If I found it, it would go in a frame.
