Ideas for line tagging system?
Ideas for line tagging system?
(OP)
I know this has been discussed before, but I want to bring it up again: I would like to hear different people's methods of labeling lines on a set of multiple P&IDs. Right now I have 1"-SS1-001 (line size-pipe material-sequence number), but it gets very messy each time I add or delete a line. So now the lines on a P&ID seem entirely random. I've read about using Equipment From:Equipment To in the tag, but my main issue with that is how do you label a pipe that is connecting between two other pipes, or T's? I would love to hear people's systems that they commonly use.
Thanks!!
Thanks!!





RE: Ideas for line tagging system?
For a multiple operation units plant, the line number is based on the "units" and "process", such as:
1001 -P -0001 -1" -SS1 -PP
(unit#- process index- sequence #- line size- piping class- insulation type)
The four digits of the unit# and sequence# provide a flexibility, which are used to group the pipes in the same unit through the multiple P&IDs. And, it may further be used to separate the lines for each P&ID in that unit.

Your final selection of a "line tagging scheme" must be in accordance with the desired format of your line lists.
