Is it true that, at the stage of construction drawing design, all the calculations required on the PID diagram have already been completed? For example, the calculation of safety valves and steam traps, pipe diameter calculations, pump flow rate and head, heat exchange area, insulation thickness, and so on. All of the above was completed during the preliminary design phase, right? What other important design aspects are there for the process and system at this stage?
All of this should be completed during the preliminary design phase; the construction drawings are already far behind schedule. It is important to provide materials available for **review, various specialized articles.
That’s for sure! ! ! ! 1
The PID diagram is completed at the conceptual design (or preliminary design) stage, and it is detailed enough to enable the preparation of purchase requests for materials such as pipes, valves, measuring instruments, etc. During the detailed design (or construction drawing) phase, piping diagrams or single-line drawings are prepared.
During the detailed design (or construction drawing design) phase, piping diagrams or single-line drawings are prepared, along with a list of materials required; the route and height of the pipes, as well as the installation locations of the pipe fittings, are also determined
