Please ask an expert to help with questions regarding process flow diagrams
Thread Content
In process flow diagrams, there is a style in which all the equipment is placed on the same horizontal line, and another style in which they are distributed across the plane. What is the difference between these two? Is one only for sketches, while the other is considered a piping and instrumentation diagram? Where is each of them applied? What is the basis?
I have no idea what you’re talking about; please use diagrams to illustrate the two situations you mentioned. I simply can’t understand what you’re saying.
You might be referring to the piping layout diagram; is there also a equipment plan? Equipment foundation plan? Flowcharts fall under the category of process flowcharts. The basis is the various types of drawings included in the overall design plan of a project. It is recommended to find this general plan, which contains a list of drawings, and select the ones needed for your assignment.
The first diagram is the common PID diagram, a process flow chart with control points. It’s drawn very clearly and in a highly standard manner. The second diagram seems quite simple; it won’t be used as a PID diagram. It can be understood as PFD.
Hello, for the second one, the drawing I have available isn’t suitable for public use, so I found a simpler one. If such a drawing also includes complete control point and pipeline information, could it still be used as a PID drawing? Why are the PID diagrams we commonly see in the first format? Is there any consensus within the design industry regarding this?
Hello, I’m inquiring about a process flow diagram similar to the second one; if instrument control points and pipeline information are added to it, would it have the same effectiveness as the first PID diagram? Also, in the design documents I’ve seen so far, it’s all in the first format; is it possible to use the second format for generating PID diagrams?
So, there are no strict requirements regarding the layout of the equipment, right? Can both of these layout styles be used to generate PID drawings as long as the information is complete?
