PID (Piping and Instrumentation Diagram)
A Piping and Instrumentation Diagram (P&ID) is a detailed technical drawing that visually represents the layout of a process plant’s equipment, piping, and control devices. It shows how machinery, valves, instruments, and pipelines are interconnected to control and monitor operations, such as in manufacturing or energy production. P&IDs are used by engineers and technicians to design, operate, and maintain systems efficiently, ensuring safety and functionality. They combine symbols and lines to give a clear overview of how different components work together within a complex process.
