Are the upper nozzles on the head, except for N1 which is a tower-attached pipeline, all the same?

N14 is the safety valve interface, P1-1 is the local pressure gauge interface, and N2 is the vent port. I would like to ask whether these interfaces need to be connected to the tower pipelines? Should the pressure gauge and valve still be installed at the top of the device?
There are no top of tower pipelines, right? Only the middle one is the Takeover, right?
Pipelines and valves need to be installed, and a platform must also be welded at the upper part of the tower, leaving some extra space.
I want to ask whether P1-1 and N2 have a reverse J-shaped pipeline extending all the way to the bottom of the equipment, just like N1. For N1, it is a pipeline at 0° to the tower; at 0° I cannot design lifting lugs as they need to be avoided. Will P1-1 have such a pipeline?
