Symbols Of PId. Process engineers use various pid symbols while constructing pid drawings. Equipment, piping, vessels, heat exchangers, pumps, instruments, and valves.
The most popular symbols are actuators, equipment, flow elements, instrumentation, piping fittings, valves and more. Process equipment such as valves, instruments, and pipelines are identified by codes and symbols. Piping and instrumentation diagram, pids, are detailed drawings used in the process industry that depict piping and process equipment, instrumentation and control devices along with safety systems in place that ensure the process remains running in a safe operational state.
