Study Notes
P&ID vs PFD
- The P&ID diagram includes more detail than the PFD.
P&ID Details
- Shows the details of equipment orientation, piping, instrumentation, and control systems.
- Provides information about equipment orientation.
Purpose of P&IDs
- In operation, repair, and modification of the plant, P&IDs serve as a guide for operations, maintenance, and engineering staff.
- During design and pre-construction phases, P&IDs facilitate communication among designers, engineers, and operators.
- For field construction and inspection personnel during construction, P&IDs provide a detailed guide for installation and inspection.
- After construction, P&IDs serve as a reference for plant operating and engineering staff.
Control Loop Components
- In Figure 7, the instrument that senses the tank level is not specified.
- The level controller sends an electronic signal to the diaphragm-operated level control valve.
- The instrument that records the tank level is not specified.
- The control system indicated by the control lines in Figure 7 is a feedback control loop.
P&ID Content
- Typically includes information about equipment, piping, instrumentation, and control systems.
- Does not typically show information about civil foundations or building layouts.
