A piping and instrumentation diagram (P&ID) is a detailed graphical representation that illustrates the interconnection of process equipment, piping, instrumentation, and control systems within a process plant or facility.

What is a piping and instrumentation diagram (P&ID) used for?

• Piping and instrumentation diagrams (P&IDs) act as a foundational blueprint during the design phase.

• They provide a clear visual explanation of how a process works.

• Operators use P&IDs to understand operational procedures, control loops, and system interconnectivity for day-to-day management.

• Piping and instrumentation diagrams (P&IDs) offer a reference point for effective collaboration among engineers, operators, maintenance personnel, and other stakeholders.

P&IDs are fundamental documents in process engineering, providing vital information for safe, efficient, and compliant design, operation, and maintenance of industrial processes.
