Legend in the PID diagram

What is used to represent the reducer tee in the PID diagram? ? ? ?
There’s no need to represent reducer tees in the PID diagram; locations where the diameter changes can be indicated using elbows instead

PID does not refer to elbows or tees
Shouldn’t an isosceles trapezoid have a changing diameter?
Actually, I think it can be represented using intersecting lines and valves, with each pipeline having its properties labeled – this way it can also be explained clearly. In a PID diagram, pipes that intersect but are not connected usually need to have their lines broken.
