PI Diagram

A PI diagram is the basis for the drafting of an entire process plant in a 3D model and also the heart of the plant’s structure.

A PI diagram (Piping and Instrumentation Diagram) is a detailed pipe and component diagram. It is used in the process industry to create a transparent and systematic overview of the process equipment and its context.

In a detailed piping and instrumentation diagram the following is often included:

  • Pipe and pipe sizes
  • Pipe numbering
  • Components such as instruments, valves, pumps, containers and heat exchangers
  • Component numbering

Possibly a link between the instrumentation and control devices

We offer

Process Engineering has great expertise within design and handling of PI diagrams, and, together with you, we design the right process for a specific plant.

The design of a PI diagram often relies on an amount of process data that typically comes from laboratory or pilot projects. We use these process data to design the diagram. Throughout the entire design phase we conduct reviews to ensure that you get the best design in terms of productivity, safety and maintenance.
