Tank you moverZ for your reply,
I think it can't be a good solution to add too much supports having very little spacing between them compared to the pipe reasonable support which you mentioned it as 23m. However I have support spacing of 8 meters as the pipe is on a pipe rack. I don't have this big load there but on the supports near a 3D expansion loop.
I estimated the system load full of water something arround the one you calculated but the problem is I don't have 23 meters between supports. It is arround 15 meters.
for the other part of the system (The riser I described above) the load itself may be reasonable to some extent but I don't dare handling it via a turnnion!!!
