This brief guide provides you with the basic knowledge of P&ID and a step-by-step tutorial on how to draw an effective P&ID with Edraw.

The Definition of P&ID

P&ID, short for piping and instrumentation diagram, is a detailed diagram that represents the technical realization of a process by means of graphical symbols, such as the service lines, instruments, controls, valves, and equipment. It is often used by engineers and technicians to understand the process better and how the instrumentations are connected.

  • Piping Designers
  • Instrument Engineers
  • Process Engineers

What Does a P&ID Used For?

  • It shows the inner relationship of how each instrument is connected.
  • It shows the relative location of equipment, actuators, and instruments in a process.
  • It depicts a conceptual outline of a plant and its control architecture.
  • It provides a common language for documenting, discussing, and analyzing a plant.

Add Symbols with Proper Annotation

When a drawing page is open, the corresponding symbol library will also open automatically on the left of the canvas. For example, if you open a Utility-Generation P&ID, you will see the libraries of ductwork, blowers, boilers, chemistry, containers, heaters, HVAC, logistics, machines, mixers, motors, powers, pumps, and tanks. You can close the libraries you don't need, or open other P&ID libraries.

Drag a symbol you need and place it on the canvas. All symbols are in vector format, which means you can change the colors freely or zoom in to a bigger size without any clarity loss.

To add an annotation, go to Home tab, click Text button and drag a text box to type the description.

Save and Export

After it's done, you can right click on your mouse and choose fit to drawing.
