We don't stock a tube in the size you mention but do have a couple either side of it.
When making long tubes in carbon you generally do not "screw" them together or try to make any thread in carbon as threads in carbon are either very weak or just turn to dust.
To make such a tube, you would use a slightly smaller diameter tube as a joining piece that slides inside the larger tube such that the stress and strain in the join area can be spread over a wider area thus meaning the join doesnt need to be such a vulnerable weak point.
The inner tube is often bonded in for such applications although you must rough the bonding surfaces, both to create a better mechanical bond as well as to remove any remaining release agents or contaminants from the original roll wrapping process used to make the tubes.
