The Piping and Instrumentation Diagram is the road map for completing Piping Layout/Arrangement Drawings. The Piping and Instrumentation Diagram (P&ID) is developed from the Process Flow Diagram (PFD) and is a schematic drawing representing the process equipment, showing nozzles, all pipes and in-line fittings (valves, tees, reducers, strainers, sight glasses, drains, vents, sample points, control valves etc.) instruments and control loops (but not instrument piping), and some electrical data such as tracing and motor drives.
Larger plants will have a separate Utility Diagram which shows all utility lines servicing process lines and equipment. Utility lines would consist of steam, condensate, water, air and possibly inert gas etc. In a small plant all process and utility piping would be included in the P&ID.

Ya this is good design practice for all engineers bcz. in ur list it should always to folw in piping design. which r make on p&id…
very cooli will love to learn such drawing i am in a company were such is applicable
