Drilled Threaded plug and Solid Threaded plug
(OP)
When looking at the P&ID , I was confused the use of drilled threaded plug or solid threaded plug at the end of drain or vent line. Please advise what occations are suitable for drilled plug. Thanks.

You asked:
"Please advise what occations are suitable for drilled plug."
I have the feeling that this is a trick question. The answer is "None". A plug is a plug. A plug with a hole in it is NOT a plug.
You said you saw this on a P&ID.
What is the process or what kind of plant is this?

You should find the process engineer that made the P&ID or was responsible for creating the P&ID and ask them what is the purpose of, and function of, the through hole drilled in the threaded plug.
Good luck.
Please let us know what you find.

What is in this line?
If it is a "Toxic" gas (or fluid) then you would not want to do this.
A minor question.
What does the "P" in the "Box" tag mean and are these flange connections?

The product is LNG at -265°F and 265psig. But the line highlighted is tank discharge line PSV inlet and outlet. NNF.
pennpiper, if you are asking the <P> at one side of valve, it means pressure preferred side.
Thanks again.
