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

Draw a P&ID with Edraw
Here shows simple guidelines on how to make P&ID with Edraw
Start a P&ID Drawing Page
Start Edraw, from Available Templates, choose Industrial Automation. The templates window on the right will appear five P&ID drawing templates. Choose one based on your own purpose, and double click to open.
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.
