You mean they'll be standing vertically? In that case, absolutely not. They
don't have any appreciable strength and will be the weak link in the system.
Round pipes in general are not suitable unless they're 6" well casing or
something similarly brute. A much better choice of material is H-beam with
6" or so flanges. For tall tower use, there is usually a flat plate welded on
the bottom at a right angle to the tower to provide more material surface
area. And it doesn't hurt to back-guy the thing.
