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


19/39


Equipment

- all equipment with exact number and components :

all noles, manholes, internals

- type of connection to piping

- equipment item number, service name, ma!or

specification


20/39


Piping

- all lines for normal operation, startup, shutdown,

emergency, special operation, and maintenance

- all piping components "valves etc#$ and

notes on them "%&', %&%, (&'$

- line information : line no#, sie, fluid symbol,

piping service class, insulation

- configuration requirement : )o Poc*ets, Free Draining


21/39


+nstrumentation

- instrumentation for controlling, monitoring, emergency shutdown,

sequence control, interloc*, automatic startstop

- field instrument

- control and shutdown valves with their type, sie, failure status

- pressure relief valves with their set pressure and sie

- *ind of signal : pneumatic, electric, hydraulic, capillary tubing,

softlin*
