What we usually do is a "physicalization", when the plant is built, P&ID will be updated accordingly in order to show the components where they are, i.e. if in a P&iD is shown in sequence a TI and a TT, then in the plant are TT and TI, then PID will be updated.

I have a question regarding the insulation gasket between dissimilar material.
In nozzle on a Carbon steel vessel I fit a Stainless steel Thermowell. Since they are dissimilar material, is the insulation gasket mandatory or can be used a convetional spiral wound gasket?
Some client ask for it...
