What is P&ID?

A piping and instrumentation diagram (P&ID) represents a process system that includes the piping, vessels, control valves, instrumentation, and other process components and equipment in the system.

P&ID is widely used in engineering to show the interconnection of process equipment and instrumentation to control the design system. 

What is P&ID used for?

  • P&ID provides the details about the necessary arrangement of piping and instrumentation and – as such – it can serve for managing, maintenance, and modification works.
  • P&ID used to develop guidelines and standards for facility operation
  • P&ID is an essential tool to explain the processes workflows to engineers
  • P&ID helps to find a primary problem cause if workflow is damaged and estimate the cost of its removal
