Ok I am still relativaly new to this business and I realize I don’t know everything but I am fixing some P&ID’s and some of these marks don’t seem right. I have already asked some of the other people in the office and most of them seem to be brain dead. Ok so I have a tank and first off it is labled tk-57 instead of t-57 which seemed odd to me but thats how they want it. Well on top of this tank is a valve, it is the 3 arrows pointed at eachother symbol (left, right, and bottom pointing up) with the relief symbol on top. Isn’t this a conservation vent (CV)? They have PVRV but I haven’t seen these marked like that before so I was wondering if that was right. I was also told these were marked up by a college intern so thats why I question. Another way the are marked which is odd to me is in the instrument bubble the tank number is on top and then the pvrv-01 is on bottom. Anyone have any insite as to why it is done like this or if its all wrong. I have a hard time telling them, hey this isn’t right, when i can’t really tell them why with good facts. thanks for the help.
