P&ID Symbology
P&ID Symbology
(OP)
I have been in the equipment industry (compressors mainly) for the past 11 years. I have seen more combinations of symbols used on P&ID that I really care to. However, I have been asked to write a company standard. I sort of thought that ISA-5 would contain everything that I needed to know. For instruments, this is the case. However, for Valves, process lines, hoses & such, ISA leaves this stuff out or only addresses a few types. Does anyone know of another ISA standard for these? Any other standard such as API, ASME, ANSI, etc would also work to.

Some of the HMI software consulting houses have symbol libraries for Wonderware, etc. In fact, these may be generated to look somewhat like the equipment.
Consider finding legend sheets from the operating company or other contractors for that facility and generate similar symbols.

In your case I would suggest that when you quote you price for your own standard P&ID style and then charge extra if the client wants their own standards applied.
