Issue regarding the mismatch of pipe openings in the equipment drawings, elevation views, and pipe opening orientation diagrams
Thread Content
As the title suggests, I’ve seen several drawings where this is the case: the positions of the pipe openings in the elevation views do not match those shown in the pipe opening diagrams. I’m not sure if this is common in equipment drawings – in reality, the actual positions of the pipe openings can be found in the pipe opening diagrams. For example, in the diagram inside, the pipe openings are labeled a, b, and c. At first glance, one might think that these three openings are on the same line, but upon looking at the layout diagram, they are actually all on a circle; one might be in the east and another in the west, yet in the elevation view they are shown together
The representation of drawings for chemical engineering machinery differs slightly from that of drawings for other construction machinery: Elevation views show the relative spatial positions between components such as pipe ends and supports [the distance vertically (for vertical equipment) or horizontally (for horizontal equipment)]. Orientation views indicate the specific orientation of these components (usually expressed in terms of angles)
By looking at the top view, it’s possible to tell where it is
The 2nd floor is correct; the opening size of the pipe should be determined based on a top-view
Yes, I just wanted to confirm that the elevation view and the pipe outlet layout are different
The orientation of the monitoring port should be based on the port orientation diagram.

If conventional third-view projection standards are used, some of these nozzles cannot be shown on the drawings. To express it completely, the above approach had to be adopted. This is a disaster for designing and producing drawings using 3D modeling software.
What if the cross-section and the orientation of the pipe opening don’t match?
