What's a piping and instrumentation diagram?

Piping and Instrumentation Diagram (P&ID), which is also known as process and instrumentation diagram, is a schematic illustration in the process industry showing the piping of the process flow together with the installed equipment and instrumentation through graphical symbols. It shows how industrial process equipment is interconnected by a system of pipelines, which is required by engineers to start planning for the construction of a plant. Learn P&ID diagram knowledge.

Why piping and instrumentation diagram is important?

1. It's used as a Process Plant Layout and Piping Design reference for checking engineering and design documents and drawings associated with a project.
2. It plays a very important role in plant maintenance and modification in that they demonstrate the physical sequence of equipment and system as well as how they all connect.
3. It's the last stage of process design and serves as a guide for those who will be responsible for the final design and construction.
4. It's also used to train operators and plant simulators.

How to Create a Piping and Instrumentation Diagram?

Process and Instrumentation Template

Start with the Exact Template

In Edraw, the Process and Instrumentation Template helps you easily create piping and instrumentation diagrams using massive built-in symbols. Double click the template from Engineering Category on the starting page to enter the drawing page. You will discover abundant symbols and easy-to-use tools available for piping and instrumentation diagrams.

Create P&ID with Standard Built-in Symbols

Edraw includes more than 500 vector P&ID symbols created from different international standards. In Edraw library, all P&ID symbols are classified into groups as equipment, valves, piping lines, instruments, etc., which you can easily use to depict mechanical equipment, piping, piping components, valves, equipment drivers and instrumentation and controls. Go to Process and Instrumentation Symbols and Their Usage page to have a general knowledge about the symbols.

Process and Instrumentation Symbols

Basic Steps to Create P&ID:

1. On the File menu, point to New, point to Engineering, and double click Process and Instrumentation template. A new drawing page will open.
2. Go to the library pane on the left of the canvas. From Equipment, drag equipment shape onto the canvas.
3. Use pipelines to connect the equipments.

  1. Drag a pipeline from the Connection Shape onto the drawing page. Position an endpoint with an equipment shape. Connection points ( blue x ) will appear on the equipment shape. You can connect with any connection point as you want. When the endpoint turns red, it means it's glued to the equipment shape. Note: Connection point can be created through Connection Point Tool under Home tab if you need.
  2. Drag the other endpoint to another equipment shape as above.
  3. Pipeline style is changeable if you need a special line weight or arrow direction. Go to Home tab Line button to set the pipeline style.

4. You can add valves and instruments in the same way.
5. Rotate a shape through the rotation handle when it's selected.
6. Reposition a shape by dragging it to the required place.
7. Add data to a component by double clicking on it.

Print: When a piping instrumentation diagram is done, it's easy to print and share with more people. On the file menu, point to Print to set for print options. You can change settings with fewer clicks and see the print preview in real time.

Export: Edraw offers support for exporting your diagram to various formats, including Microsoft Office, PDF, and many other graphic formats. On the File menu, point to Export & Send for Export options.

More Features Making Edraw the Best Choice:

  1. Edraw has built in a set of nice looking themes with advanced effects. It's easy to change the whole diagram by changing the active theme with just a few clicks. You don't have to be professional in designing.
  2. All Edraw documents are vector graphic files with high clarity.
  3. Smart tools are provided for automatic formatting. Easily arrange, rotate, group and align objects.
  4. Edraw offers various customization options, using which you can adjust line width, color, style, font size and style, text color, and much more.
  5. Easy to add photos, images and edit text fields.
