Description / Abstract:
This Practice describes the requirements for PID format and
content. The Practice is independent of time in a facility life
cycle and encompasses design, construction, operations, and
maintenance.
This Practice covers the generation of new PIDs and does
not apply to the revision of existing PIDs. This Practice also
applies to PIDs provided by packaged equipment vendors.
This Practice applies to all diagrams that fit the definition of
a PID in Section 3.
The requirements provided in this Practice can be applied to any
CAD system used for developing the PIDs and are not vendor,
hardware, or software specific.
The requirements provided in this Practice provide a balance
between showing all data on PIDs and making PIDs legible
and easy to read. While this Practice is expected to incorporate
the majority of requirements of most users, individual applications
may involve requirements that will be appended to and take
precedence over this Practice. Determinations concerning fitness
for purpose and particular matters or application of the Practice
to particular project or engineering situations should not be made
solely on information contained in these materials.
The example PIDs included in the Appendixes of this
Practice are not intended to recommend specific design details or
requirements. Example PIDs are included to provide an
illustration of how the elements of this Practice are combined into
a PID.
Electronic native files for the text, symbols, and cover sheets
are available to PIP Member Companies for input to members' CAD
systems. Development of project-specific cover sheets is
recommended using the PIP native files as a starting point.
Additions and/or deletions are allowed to meet requirements. Cover
sheet borders and title blocks can be altered.
Purpose
This Practice provides requirements for designers preparing
Piping and Instrumentation Diagrams (PIDs).
