I was looking over this P&ID and not familiar with the standard of diagrams used here. Anyone familiar with these that might confirm what they are please?
Gator has put his finger on the cause of the problem ...
"Is it because lesser-experienced people are now doing drawings or using only symbols that came in the box with the software?"
Yes,.... yes indeed it is ...
There are more and more 18 year old CAD monkeys, hired right off the street or from a phone APP who could not care less about the quality of their work.
Confusion is further enhanced by a vast multitude of CAD/PID packages that were purchased by MBAs in the IT department.
Young CAD monkeys are, of course far too busy to make an index of PID symbols for each project ...
... and this mad dance is made worse by MBA PROJECT MANAGERS insisting that everything go out the door by Friday..
.... and, oh yes .... we are going to need a Process or Mechanical Engineer to PE stamp the PIDs on Thursday afternoon..
