P&ID stands for Piping and Instrumentation Diagram and utilizes a standard set of symbols to illustrate process systems flow for design, development, and operation.
What is P&ID?
P&ID, or a Piping and Instrumentation Diagram, is a detailed drawing or schematic primarily utilized in the industrial process industry to illustrate the interconnection between piping, equipment and the instrumentation devices used to control plant processes.
What is P&ID used for?
P&IDs are used to help design the layout of engineering process systems. The graphical diagrams include important information for installation or the systems included and provide detailed specifications outlining operational schemes and procedures.P&IDs are also used for systems modification and maintenance.

P&IDs are typically developed by process design engineers for industrial processes (physical, electrical, or mechanical) for product manufacturing. Piping and instrumentation engineers follow the schematics to plan and develop plant build-out and coordinate with construction teams for installation. Process operators will also use the P&ID schematics for safety, training and operation.

A PFD is a process flow diagram which is a more general illustration of plant process flow between the major equipment in a plant. A P&ID is a more detailed schematic to show all the equipment, piping, instrumentation, and connections at a plant.
A P&ID typically includes the following components:
- Mechanical equipment and machinery
- Lines and process piping
- Piping fitting specifications
- Other piping requirements (slope, special insulation, distance requirements, etc)
- Manual and automated piping valves
- Safety Values Drains and vents
- Instruments and control devices Interconnections (OPC)
- Notes and additional information
All of the major industry-standard symbol libraries are available in Plant 3D including PIP, ISA, ISO/DIN, and JIS. Learn more.
