Help: How can I understand engineering drawings for chemical projects?

1. How to read floor plans. 2. P&ID diagrams, etc. Experts with experience in this area, please help
1. To understand drawings, one must have certain knowledge of reading them. 2. Some knowledge of chemical engineering is necessary as well. 3. It is important to know the meaning of various symbols in P&IDs. 4. A basic understanding of the process flow is required
This is relatively simple; the drawings show the positioning coordinates, as well as the numbers and names of the devices. Just take a look at the name. If it is a multi-level platform, be careful not to get the levels mixed up. The layout plan is relatively simple; its main purpose is to determine the location of equipment. PID requires certain professional knowledge, but the drawings come with legends; by looking at those legends carefully, you’ll understand it. If you still don’t understand, you’ll have to ask your colleagues or those who are more experienced in the company. (You can also go and ask the designers at the design institute directly.)
It’s hard to say; if you didn’t have a solid foundation before, it’s truly difficult to understand blueprints. Here’s a useful tip: learn more and ask questions! If you use this well, it should take about half a year to get there
To have a basic understanding of drawings, it’s not enough to simply understand one drawing; the drawings are interconnected. Generally, one should first read the general introduction to understand what the project is and its key design aspects. Next, the overall plan should be examined to grasp the scope of the project and the route of the main pipelines, after which the various specialized drawings can be studied in detail. The combination of plan and elevation drawings, what each icon means, and so on. In my opinion, the main difference between chemical engineering drawings and architectural drawings lies in the fact that one must not only understand the basic technical drawings but also be familiar with flow diagrams, something that is not required for architectural drawings.
