A piping and instrumentation diagram (P&ID) is a drawing used in the process industry. The drawing shows the physical sequence of all piping including branches, reducers, valves, equipment, instrumentation and control interlocks. The detailed information presented in the P&IDs significantly helps in maintaining and modifying the process that they describe. A P&ID must include details about instrumentation and designations, mechanical equipment with names and numbers, all valves and their identifications, process piping, sizes, and identification, vents, drains, special fittings, sampling lines, reducers, increasers, and swaggers, permanent start-up and flush lines, flow directions, interconnections references, control inputs and outputs, interlocks, interfaces for class changes, computer control system and identification of components and subsystems delivered by the process.
Though many engineers are trained to accurately draw a P&ID, most of the time accuracy remains a constraint. This is where expert P&ID services like that provided by Magnasoft helps. Our expertise in working with 3D laser scanning data enables us to create precise P&IDs.
