    P&ID Symbol Pilot Operated Reducing Regulator

    Does anyone show the pilot regulator in a pressure reducing regulator with the pilot ties to the downstream line? In the ISA 5.1 document, the pilot device is only shown for the pressure relief operator. Thanks for any feedback.

    Piping Line Numbers on a P&ID

    Can anyone tell me if the piping line number changes after a reduction in the pipe, or if the pipe branches off into several sub-branches? Thanks in advance.
