A P&ID is a detailed graphical representation of a process including the piping, equipment, and instrumentation which is necessary to design to design, construct and operate the facility.
P & ID contains the symbolic information which is going to use in that system. There are set of standard symbols which used in P & IP like valve symbols, instruments symbols, equipment symbols, sp items etc.
Process and instrument diagram is unique documents which have to follow all the discipline in engineering. Process department have the authority of change process parameter on that if any other discipline have any issue in that P & ID.
Process and instrument Diagram look likes below pics.
Piping point of view
Process and instrument Diagram (P&ID) is the main basis for designing of the piping of any plants like offshore wellheads platforms, refineries, chemical plants, power plants, process plant. P&ID contains the process parameters of system like size of line, service of the line, instruments fitting like PG, TE, PDIA CC and other information related to that service and equipments.
Process and instrument Diagram (P&ID) is the first documents on the basis of piping department start working on the layout.
Typical example of the P&ID which is used in industry.
