Process Control Basics: The Piping and Instrumentation Diagram (P&ID)

P&ID's (piping &instrumentation diagrams), or Process and Control Flow Diagrams, are schematic representations of a process control system and used to illustrate the piping system, process flow, installed equipment, and process instrumentation and functional relationships therein.

Intended to provide a “picture” of all of piping including the physical branches, valves, equipment, instrumentation and interlocks. The P&ID uses a set of standard symbols representing each component of the system such as instruments, piping, motors, pumps, etc.

P&ID’s can be very detailed and are generally the primary source from where instrument and equipment lists are generated and are very handy reference for maintenance and upgrades. P&ID’s also play an important early role in safety planning through a better understanding of the operability and relationships of all components in the system.
