Thank you for your reply. I’m familiar with the fluid codes. However it confuses me with the system codes they used for establishing the plant. I’m looking for a numbering system for a new plants…It was used which they call as System Codes..(similar with KKS Numbering System)..I believe this is an EPC owned system…Is there anyone encountered working with new plants that uses System Codes?..My past experiences usually rely on KKS Numbering System which is very systematic and organized…Unlike this System Codes that i’m looking for a documentation that explains where those codes coming from…how they where derived…etc..

I’ve encountered that too with the newbie engineer commenting on my P&ID work. I’ve been in different industries and companies and all were consistent with Large Size X Small size…whatever the flow direction.

Thanks JOP.
For the Fluid Codes (e.g. IA = Instrument Air…) Is there any code or std that list all the fluid codes?..
