P&ID minium distance query
P&ID minium distance query
(OP)
Dear Sir/Madam
Positon in a P&ID don't correspond to a 3D position. Therefore, the min. distance (yellow mark) in this P&ID seems weired (please see the attach document).
Could anyone please help me what is the difference if this mim. distance is extend to the top line (the triangle break point)?
Thank you so much for your help.

It is almost certainly a minor mistake on the drawing which you have recognized- the minimum distance dimension line should run back to the tee.

- What are the line sizes"
- What is the line Class (Flange rating)?
- What is the Commodity?
- What do the little "Delta" flags mean?
And yes there is an inconsistency with the "Min" notes. Some runs have it and some do not.

You said "The "delta" flags usually mean a line number break i.e - the start of a new line number."
I sure hope you are wrong.
With what I see on the original posters attachment it would show some real bad places to break or start line numbers.

Seriously, the min comment and the long triangle are warnings the process engineer have on slope and distance

delta flag is means the class break of the pipe.
If the no. of pipe will be changed in the next line,
it should be put the delta flag in the connection.
Thank you
