Methods for drawing utility pipelines and similar elements in CAD diagrams of process flows
Thread Content
After reviewing a lot of materials, it can be seen that the pipelines for utility systems, such as steam, cooling water, and condensate, are generally not connected at the top and bottom of CAD drawings; however, textbooks show these pipelines connected to those in the flow diagrams. I’m not sure which one is more standard. Also, in many documents, the name and code of the device are shown at the bottom (or top) of the flowchart, separated by a short line in between. Yet the textbook puts these in the tables in the details column. I wonder if there are any agreed-upon standards? Please give me some advice!
In the main pipeline diagram, the utility pipes are shown only at the points where they connect to the main pipelines, followed by the reference number of the utility process diagram. And provide a separate process diagram for utilities.
Take a look at the following specification: HG 20559-1993 Requirements for the content and level of detail in the design of pipeline and instrument diagrams

Where can I find more information about this regulation?

The pipelines for utility systems must be drawn on CAD diagrams; these are what we commonly refer to as UID&. In many documents, the pipelines for utility systems such as steam, cooling water, and condensate are not connected to each other at the top and bottom of the CAD diagrams, whereas textbooks show these pipelines connected to those in the flowcharts. I’m not sure which one is more standard.
What textbooks are you using? Unreliable
For example, the CWS and LM pipelines are on top, while the CWR and SC pipelines are at the bottom.
