1MPa 250℃ DN300 steam line, buried under the road overpass; could everyone please help check whether this simulation is correct?
Thread Content
I can’t insert images, so let me describe it: there is a section where it goes down from the pipe gallery, runs underground through a conduit across the road, and then comes back up to the pipe gallery. What I don’t understand now is how to simulate support for the buried part; at the points where it enters and exits the ground, I’ve simulated guide restrictions, with a 10mm gap added in between. A guide and Y were created in the middle of the burial area. I’m not sure if what I’m doing is correct; please give me some guidance.
Steam pipelines are rather special; the model in Caesar is determined based on the type of pipe material used and the way in which the pipes are laid, with calculations generally being carried out using overhead simulation.
The approach is basically correct. Don’t you draw piping diagrams for your buried pipes? If you are drawing it, you should know how the supports inside buried pipes are arranged, and then proceed in the same way as for overhead pipes. Also, pay attention to the limits at the elbows
Oh, okay. I’ve learned it now; I roughly understand the principle. Thank you very much for your guidance.
