P&ID es un diagrama de tubería e instrumentación. Muestra la misma información que un PFD pero también muestra instrumentos, circuitos de control, medidores / sensores / analizadores, servicios públicos (agua de refrigeración / refrigeración / etc.) y PSV (válvulas de seguridad de presión). A veces se mostrará incluso más que esto.

This level of uncertainty is perfectly acceptable for a PFD, because its purpose is merely to show the general flow of the process itself, and only a bare minimum of control instrumentation. Process and Instrument Diagrams. The next level of detail is the Process and Instrument Diagram 1, or P&ID.

Difference between PFD and P&ID The process flow diagram (PFD) is used in chemical and process engineering. This kind of diagram shows the flow of chemical materials and the equipment involved in the process. In other words, a process flow diagram will tell us the relationships between the major components in the system.

existing P&IDs. This Practice also applies to P&IDs provided by packaged equipment vendors. This Practice applies to all diagrams that fit the definition of a P&ID in Section 3. The requirements provided in this Practice can be applied to any CAD system used for developing the P&IDs and are not vendor, hardware, or software specific.
