Just for the record of this thread, I probably got the meaning of "P" value, i.e. the external design pressure to which the calculated maximum allowable external pressure must be compared (greater than).
If Pint = 0 bara (full vacuum) --> P = 1 - Pint = 1 bara
If Pint = 0.2 bara --> P = 1 -...
Thank you all for your replies.
I am using exclusively bara: I am considering 1 bara outside the pipe (i.e. atmospheric pressure) and 0.96/0.90/0.2 bara inside the pipe (examples given).
[In barg, of course it would have been 0 barg outside and -0.8 barg inside].
In any case, Pext > Pint.

Hi everyone,
My company is verifying some piping classes for a future carbon capture and storage plant design.
Some parts of the plant (with sizes from 30" through 92") will have internal pressure slightly below atmospheric pressure (e.g. 0.90 bar) but even much lower atmospheric pressure (e.g...
