There are standard symbols used to represent the components in these diagrams. P&IDs also are used as the basis for the live graphic representation of a process system in its HMI (human-machine interface) or other control system.
Installation and/or build-out of the system.Safety and operational analysis (HAZOP – hazard and operability study).
As such, the P&ID is crucial in all stages of process system development and operation. The P&ID is the primary schematic drawing used for laying out a process control system’s installation. A piping and instrumentation diagram (P&ID) is a graphic representation of a process system that includes the piping, vessels, control valves, instrumentation, and other process components and equipment in the system.
