P&ID Drawing Guide
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.
Who uses P&ID
- Piping Designers
- Instrument Engineers
- Process Engineers
- Electrical Engineers
- Mechanical 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.
How to Draw a P&ID with Edraw
Here shows simple steps on how to make a P&ID with Edraw
Start a P&ID Drawing Page
Start Edraw, from Available Templates, choose Industrial Automation. The template window on the right will show five P&ID templates. Choose one template as the basic of your P&ID drawing, and double-click to open the template.
All-in-One Diagram Software
- Superior file compatibility: Import and export drawings to various file formats, such as Visio
- Cross-platform supported (Windows, Mac, Linux, Web)
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.
Since others may not have Edraw, you might need to export the document to other formats so that other people can open. Click File tab, and go to Export & Send. There are many formats available including PDF, Word, Html, Visio, PPT, BMP, EMF, PNG, JPG and much more.
