Posted: Tue Jan 07, 2025 6:26 am
Discover what a P&ID is, its advantages, how to design one and how the software optimizes diagram models.
What is a P&ID?
P&ID or simply PID stands for Tube and Instrumentation Diagram .
Several fields of work use flow diagrams to organize work models. The P&ID applies to industrial and engineering projects, such as electric and steam boilers, and demonstrates pipe components, such as valves and equipment.
A brief history of P&ID
The P&ID is an extension of the DFP (Process Flow phone library Diagrams), which were created in the 1920s by the industrial engineer Frank Gilbreth and have been used for more than a century to graphically represent all the stages of the production process with very detailed information.
While a process flow diagram includes details about how the equipment works after installation, a P&ID shows detailed information about the work flow, such as motors, tubes and other units of the machine.

What is the objective of a P&ID?
The P&ID graphs represent the development of control systems, as well as the maintenance and modification of processes.
It is based on the construction of physical plants and has a schematic illustration of the relationship between the different components in the fields of automation, instrumentation and control.
Basically, a P&ID is an important document that accelerates changes and guarantees greater security and efficiency of the process. Some of the main features are:
Details about tubes and instruments
General and mandatory security requirements
Details about equipment control and shutdown
Information on when to start operating
What are the advantages of a P&ID?
P&IDs are commonly used in industrial engineering. Some of the main advantages are:
It is a global language
Professionals from all over the world can understand this diagram model developed with easy-to-understand symbols, which facilitates global communication and industrial automation.
Allows precise evaluation of processes
A well-elaborated P&ID guarantees a more precise evaluation of processes, in addition to guaranteeing a more solid basis to control the entire flow.
Help in security planning
Furthermore, the processes are safer as the visual representation facilitates the identification of points of attention.
P&ID Symbols
As in any flow diagram, the P&ID has a set of symbols that facilitate the understanding of processes through a visual representation.
Team
Use symbols to represent installations and devices used in each operation.
Pumps
Pumps use pressure to move fluid inside and outside industrial installations.
Heat exchangers
These include devices that transfer heat to a medium area, such as boilers and condensers.
Shapes of tubes and connections
They represent tubes that connect the parts of a complete system, transport fluids and can contain blocks of different materials.
Ships
They store liquids and can even change their characteristics. The tanks and columns are some examples.
Instruments
Responsible for measuring and controlling aspects such as temperature and pressure.
Valves
The valves regulate the flow of fluid in the pipe systems by opening and closing the pipes.
How to create a P&ID?
A P&ID must include all details of tube and instrumentation processes, from inputs to equipment. The diagram should illustrate the sequence of work steps and how they connect to each other.
Each symbol used represents a system component and describes its function and measurements on a specific device.
Consult important information below:
In the circular symbols, the dividing line represents the type of setup. A continuous line means setup in the control room, while a line of points means setup in the technical room. If there is no line, the application is suitable for field application.
The components control signals show input and output and can be discontinuous or wavy lines.
A P&ID must also have a TAG identifier that informs the area where the equipment is inserted, the serial number, the measurement variable and additional functionalities.
It is essential to include details such as mandatory valves and flow direction.
The P&ID representations are easy to understand. Avoid excessive details that could be added to another separate diagram.
Run simulations to evaluate the quality of the diagram.
What is P&ID software?
The P&ID software makes it easier for engineers to automate the design of flow diagrams and make projects more accurate.
The technical design is complex and requires a lot of time, so dibujar by hand or with the help of very simple tools like Excel may not help as expected.
That's why having P&ID software is crucial to creating accurate flow diagrams with all the necessary information and generating a positive impact on results.

Design P&ID diagrams in a process simulator
A process simulator can help engineers and other industry professionals who seek to improve the quality of their diagrams.
The specialized software optimizes the representation of components and processes, and offers a wide range of intuitive, intelligent and easy-to-use features.
SYDLE ONE, for example, makes routines more agile and flexible through features that allow you to simulate processes and track all assets used in the production chain.
The platform can be easily integrated with other business systems, improving processes from start to finish.
