How to read a piping and instrumentation drawing? [Video]

A piping and instrumentation diagram (P&ID) is a detailed diagram in the process industry which shows the piping and vessels in the process flow, together with the instrumentation and control devices. They usually contain the following information:

    Process piping, sizes and identification, including:

        Pipe classes or piping line numbers
        Flow directions
        Interconnections references
        Permanent start-up, flush and bypass lines

    Mechanical equipment and process control instrumentation and designation (names, numbers, unique tag identifiers), including:

        Valves and their identifications (e.g. isolation, shutoff, relief and safety valves)
        Control inputs and outputs (sensors and final elements, interlocks)
        Miscellaneous - vents, drains, flanges, special fittings, sampling lines, reducers and increasers
        Interfaces for class changes
        Computer control system
        Identification of components and subsystems delivered by others

To learn the basics of P&ID symbols and drawings and how to read a P&ID drawing we recommend these courses on UDEMY, the global online self learning platform with over 10000 Courses.

To learn more on the "Basic guidelines and applications of Control Valves" [Click Here]  P&IDs are originally drawn up at the design stage from a combination of process flow sheet data, the mechanical process equipment design, and the instrumentation engineering design. During the design stage, the diagram also provides the basis for the development of system control schemes, allowing for further safety and operational investigations, such as a Hazard and operability study (HAZOP). To do this, it is critical to demonstrate the physical sequence of equipment and systems, as well as how these systems connect.

Kindly find in the image below P&ID symbols used in P&ID drawings for different valves and pipings used in process flow  and P&ID diagrams.

P&IDs also play a significant role in the maintenance and modification of the process after initial build. Modifications are red-penned onto the diagrams and are vital records of the current plant design.They are also vital in enabling development of;

    Control and shutdown schemes
    Safety and regulatory requirements
    Start-up sequences
    Operational understanding.

P&IDs form the basis for the live mimic diagrams displayed on graphical user interfaces of large industrial control systems such as SCADA and distributed control systems.
