What does it mean on a PID diagram? ? ? PG-315101-500-AECA9-ST
Thread Content
PG-315101-500-AECA9-ST is on the five-loop PID diagram. . . . . Could an expert please explain what this means? . . . , thank you
PID diagrams usually come with legends for explanation; check to see if there is any such indication – it seems to be the **channel number**. PG-315101-500-AECA9-ST PG — Material code 313101 — Pipe serial number 500 — Pipe diameter AECA9 — Pipe grade ST — Gasket code
ST is not a gasket code; it stands for steam tracing (ST). It’s possible that the medium in this process gas (PG) pipeline may crystallize.
What do the various codes for AECA9 specifically mean? . . . . Thank you. . . .
There are a few differences from the second floor model: PG-315101-500-AECA9-ST. PG: Material code. 315101: Pipeline number, where generally 315 represents the unit number, and 101 represents the pipeline number for that unit. 500: Pipe diameter, though it is generally expressed in inches. AECA9: Pipe material grade. ST: Insulation material, which is somewhat different from that on the second floor. I would also appreciate it if experts could provide feedback.
What 15# said makes a lot of sense! Support it! :victory:
“st” generally indicates that the pipeline requires steam tracing
I’m learning *PID; coming to take a look too
Each design institute uses different pipe grade codes
