In the PID, should the flanges, threads, and whether a short pipe is needed be indicated?

I need short tubes; nothing else, unless there are special requirements
In PID for the process engineering field, should flanges, threads, and whether short pipes are needed be illustrated? Otherwise, how can those specializing in piping (3D) tell which parts are flanges and which ones are threads? How do I draw it? Each pipeline has a corresponding material grade table, which defines the types of connections for the pipelines. The number of flanges and elbows is determined by the pipeline layout, and it cannot be shown. Flanges for connecting equipment, valves, instruments, etc., should be drawn.
The images have been uploaded; see the top – they show the representation methods in PID for threaded and flanged connections respectively
For short pipes, flanges are required; threads are not needed. There are specialized professionals who create piping diagrams
List the standard specifications; for special requirements, draw them out
The first time I saw it, the safety valve had threads. For plug welding, what is the drawing method? It seems to be a drawing method used in axonometric diagrams.
For socket welding, nothing is drawn to represent it

Well, I’m not familiar with this area, thanks!
As for PID, the short sections of the pipe are generally not drawn separately, unless the material of the pipe differs... An interface separation is required. As for bolts and such, the corresponding bolt length and quantity will be determined based on the pipe diameter and weight rating used
