P&ID Examples


Piping and instrumentation diagrams represent the important components of a physical process flow. Lucidchart is a web-based application for building P&IDs and other technical diagrams. Try the simple drag-and-drop interface and online sharing options. You can even access your diagram from any device or location.

Want to make a Diagram of your own? Try Lucidchart. It's quick, easy, and completely free.

Make a P&ID with Lucidchart

Piping and instrumentation diagrams are typically created by engineers who are designing a manufacturing process for a physical plant. These facilities have complex chemical or mechanical components and processes, which are modeled with diagrams. Use Lucidchart's intuitive interface to make your own P&IDs. Our keyboard shortcuts, interactive elements, and comprehensive symbol library make it the perfect choice.

For a review on how to make a P&ID, check out this guide. The concept can be kind of tricky, so we recommend that you jump right in with the following templates and practice for yourself.

P&ID templates

We understand that diagramming can be tricky at times, which is why Lucidchart has been built to include templates and examples that can help you to gain inspiration. Try out the following templates by clicking on the link below.
