- 1. －P&ID－ Piping & Instrument Diagram
- 2. What is P&ID Basic Engineering document Indicating -Process Requirement -Equipment in the Plant -Piping and Piping Component -Instrument and Logic Relations
- 3. What should be indicated on P&ID? Process requirement - PFD : all line and flow, every item - not on PFD : relieving system, pump minimum flow, compressor anti surge flow, isolation system - item for maintenance, operation, pre-commissioning, commissioning, start-up
- 4. What should be indicated on P&ID? Equipment - all equipment with exact number and components : all nozzles, manholes, internals - type of connection to piping - equipment item number, service name, major specification
- 5. What should be indicated on P&ID? Piping - all lines for normal operation, startup, shutdown, emergency, special operation, and maintenance - all piping components (valves etc.) and notes on them (CSO, CSC, TSO) - line information : line no., size, fluid symbol, piping service class, insulation - configuration requirement : No Pockets, Free Draining
- 6. What should be indicated on P&ID? Instrumentation - instrumentation for controlling, monitoring, emergency shutdown, sequence control, interlock, automatic start/stop - field instrument - control and shutdown valves with their type, size, failure status - pressure relief valves with their set pressure and size - kind of signal : pneumatic, electric, hydraulic, capillary tubing, softlink
- 7. What should be indicated on P&ID? Other - battery limit between client and contractor - area battery limit - change of responsibility between Piping and Instrument, Contractor and Vendor - extent of packaged equipment supply - breaks of line information : line number, piping service class, insulation
- 8. What information can you get? For Equipment Outline/Internals For Piping Line No./Size/Material/Insulation/Line Configuration/Piping Component Type For Instrument Tag No./Function/Control Method
