P&IDs are indispensable tools in process industries, providing a standardized and visual representation of complex systems. From enhancing communication and safety to optimizing operations and facilitating maintenance, P&IDs play a vital role in every stage of a facility’s lifecycle. Understanding the symbols used in P&IDs and following a systematic approach to their creation ensures that these diagrams serve their intended purpose effectively, contributing to the success and efficiency of industrial processes.

Barreldistortion

“Barrel” distortion is a true optical distortion caused within the lens. It manifests as an outward bowing. Straight lines are rendered as if they were inflated. Wide-angle lenses are most susceptible to this, including the shortest focal lengths of many zooms. The degree of ballooning will vary from lens to lens.

There is also the convergence of the vertical lines because I had to tip the camera up to take in the fountain. Whenever the back of the camera is not parallel to the structure, there will always be that convergence unless you have a tilt-shift lens to correct it in-camera.

Pincushiondistortion

I’ve been meaning to do a short piece on lens distortions for some time. We hear about wide-angle distortion and telephoto compression, and there is some truth to those, but in reality, there are only two true optical distortions.

A heat exchanger efficiently transfers heat between different areas or mediums. Examples within this category include boilers, condensers, and other heat exchangers.

An instrument measures and occasionally regulates quantities like flow, temperature, angle, or pressure. You’ll find indicators, transmitters, recorders, controllers, and elements within the instrument category.

P&ID is a schematic representation that illustrates the interconnection of process equipment and the instrumentation used to control the processes in a facility. A Piping and Instrumentation Diagram (P&ID) is an intricate visual depiction of the system’s components, including piping, instruments, valves, pumps, and various equipment. P&IDs offer standardized and detailed means of visually representing intricate processes, assisting engineers, operators, and stakeholders in comprehending the design and functionality of the system.

A valve manages fluid flow in a piping system by opening, closing, or partially obstructing passageways. This group encompasses rotameters, orifices, and various other valve types.

Study the symbols legend to interpret valves (control, check), instruments (flow meters, pressure gauges), and equipment. Lines with letters (P, T, F) denote process variables (Pressure, Temperature, Flow). Pay attention to instrumentation tags for details on each device. Identify control loops and interlocks, often depicted by feedback lines and symbols.

A pipe serves as a conduit for transporting fluids. Piping comes in different materials, such as metal and plastic. The piping assembly includes individual, multiple-line, separators, and other piping devices.

A heat exchanger efficiently transfers heat between different areas or mediums. Examples within this category include boilers, condensers, and other heat exchangers.

If you have a large enough screen (you’ll probably not see it on a phone) and can enlarge this, you can see the gapping between the known straight red lines and the corners of the fountain. The gapping is more pronounced on the right because it is physically closer to the 16mm uncorrected lens.

Creating a P&ID involves several steps, from gathering information about the process to producing the final diagram. Here’s a step-by-step guide:

Organizations like Rishabh Engineering play a crucial role in supporting the development of P&IDs, especially in large and complex projects. Here’s how a multidiscipline engineering company can assist you:

Q. What are P&ID Use Cases? A. Listed below are essential applications of P&IDs across engineering and industrial processes.

“Pincushion” is a true optical distortion diametrically opposite to barrel. Pincushion manifests as an inward bowing. Straight lines are rendered as if they were being squeezed from the sides. True optical distortions are distinct to the formulation of a lens. Telephotos, including long zooms, are most likely to suffer from pincushion.

In the complex world of process industries, effective communication and documentation are crucial for ensuring safety, efficiency, and successful operation. The Piping and Instrumentation Diagram (P&ID) is vital in this domain. With this article, we will explore what is P&ID, its significance across diverse industries, the symbols employed, and a comprehensive guide on crafting them.

Not perhaps the best example, but the lens used for this picture is a Sony/ZEISS Vario-Tessar 16–70mm f/4.0, pulled back to 16mm WA. It replaced my kit 16–50 and is an excellent lens. Its slight barrel distortion is most visible on the right side of the fountain. There is a distinct outward bowing of a perfectly square corner. This render is the SOOC raw capture, no editing, no lens corrections, zeroed out.

The equipment category consists of various P&ID units that do not fall under other specified categories. This group encompasses hardware such as compressors, conveyors, motors, turbines, vacuums, and other mechanical devices.

I thought the color version was so monochrome that it might work better as a BW conversion. The sun was just barely up so there was little color. I added some selenium toning as I would have done making the print in my wet darkroom, but digitally it is less toxic and smelly and does not stain my shirts.

Understanding the symbols, flow direction, and equipment relationships helps interpret the entire process. P&IDs are essential for design, operation, and troubleshooting in chemical, petrochemical, and manufacturing industries. Regular practice enhances proficiency in reading and comprehending these diagrams.

A vessel serves as a receptacle designed for holding fluids, with the potential to modify the fluid’s characteristics over storage. This category encompasses tanks, cylinders, columns, bags, and various other types of containers.

P&IDs have limitations, such as potential complexity leading to comprehension challenges, static representation without real-time data, and the risk of becoming outdated due to system modifications. They may lack intuitive 3D spatial information, hindering visualization. Additionally, P&IDs might not capture dynamic process behaviors or account for human factors. Their effectiveness depends on the accuracy of initial design information and the diligence of updates, making them susceptible to errors and inconsistencies in evolving industrial environments.

P&IDs use a standardized set of symbols to represent various components and instruments. Understanding these symbols is essential for interpreting the diagrams accurately. Here are some common P&ID symbols:

In lightroom (or any other raw processor), I can apply lens corrections to eliminate the barrel distortion. Lightroom’s onboard lens corrections will straighten the lines unless it's very severe. Further, I applied a perspective correction to perfectly parallel the vertical lines, as shown by the white lines above.

P&IDs are essential tools in the engineering and manufacturing industries. Reading P&IDs is crucial for understanding the process flow in industrial plants. Start by identifying major equipment such as pumps, tanks, and vessels. Follow the flow of piping, noting valves, instruments, and fittings. P&IDs use symbols to represent components, with arrows indicating the flow direction. Dotted lines may represent secondary systems like utilities.
