Yes, it's my bad I was thinking it is Graphite. I looked closely and found it's some kind of thick metallic plates adjoining around the heaters. It's nothing like the graphite or the thin metal plate found on the other tubes.
I suppose this gives quite a heft to the weight of the tube but I also think it's more susceptible to the heating and cooling effects inside the tube. Other than the annoying ticking / clicking sound, it's quite a well made tube so I think the subsequent heating and cooling will not damage this tube at all even if it goes on for another 100 year. But the tube life is around 2000-3000 hours or even less in some cases so I guess they are expected to get tossed out sooner than later.
