P&ID is an initialism that could mean:

A P & ID is a full diagrammatic representation of a process plant. Each piece of equipment is shown along with its connectivity to other equipment. It may be regarded as an enhanced process flow diagram which shows, in addition to the process itself, details such as control and instrumentation equipment, pump and pipe sizes etc. Each instrument / piece of equipment is shown by a symbol denoting its type (pump, sensor, valve etc.) and a unique identification number or tag for differentiation from others.
