Piping and Instrumentation Diagrams

The Piping and Instrumentation Diagram is used to display a plant’s technical equipment. The plans show the structure and function of process plants and are part of the complete technical documentation that is necessary for the planning, construction, on-site installation, administration, commissioning, operation, maintenance and decommissioning of a plant. They also aid in the exchange of information between those involved in the development, construction, on-site installation, operation and maintenance of process plants.
