Piping and instrumentation diagrams (P&ID) are a schematic representation of the piping process with mechanical details of equipment, instruments, piping, valves, and control loops, all necessary to ensure safe operation of the facility. In other words, they are plans that, in addition to showing the sequence of operations of the Process Flow Diagram (PFD), show […]
