P&ID (Piping and Instrumentation Diagram)

A Piping and Instrumentation Diagram (P&ID) is a detailed schematic that visually represents the physical flow of systems in industrial processes, such as manufacturing or chemical plants. It shows pipes, equipment, valves, sensors, and control instruments, illustrating how they connect and interact. P&IDs help engineers and technicians understand, design, and troubleshoot the system efficiently, ensuring safe and effective operation. They are essential tools for maintaining process integrity, facilitating communication among teams, and documenting system layout for future reference.
