How to model the equipment in caesarii
Thread Content
Let’s discuss how to model equipment in Caesarii. For example, is it necessary to include a horizontal heat exchanger in the model created in Caesarii?
The additional displacement at the pipe outlet can be calculated, and then this displacement is added to the connected pipes
I haven’t used Caesar; we still use the older version of GLIF. Generally, when I perform calculations on pipe stress, I do it up to the device interface – that is, I determine the initial thermal position of the device’s pipe connections, as mentioned earlier. Then the thrust exerted by the pipeline on the equipment can be calculated. This is what I do for larger devices. I built a steam ejector device some time ago. It is relatively small, and the equipment is also considered as part of the pipeline. Calculate up to the fixed bracket. Our program works like this. It can end at a node (either a free end or a fixed end; just define that node). The calculation results are quite similar to those obtained by comparing the device outlets; they are essentially the same.
In CII, initial displacement can be added to the equipment modeling; this value can be calculated manually or provided by other specialists (if possible). If you think the value provided by others may not be appropriate, you can carry out the modeling yourself. If CII modeling is done in the same way as pipeline construction, it is necessary to determine parameters such as operating temperature, design temperature, design pressure, and material based on the equipment drawings. At the location of the nozzles, master-slave connections are used, that is, the CNODE points (equipment nozzle nodes). By constructing the equipment in this manner, the software will automatically calculate the thermal expansion of that section of the equipment and its impact on the pipelines.
It can be imported, but there are certain requirements regarding the format of the model
I agree with what was said on the 4th floor: if you have all the necessary information, it’s more accurate to do the calculations yourself; but if the situation is complex, it’s better to rely on the data provided by professionals. At the very least, we need to know how to do the calculations ourselves; even if someone provides us with the data, we can still carry out the calculations!
If it were me, I would consider the weight and size, and use a thicker pipe to simulate it
We all build using the pipeline model, with weightless rigid components used to create nodes on the equipment walls
The Cii help contains simulation methods for horizontal containers; you should check the help first
No need; if the pipes are relatively small compared to the size of the equipment, it can be assumed that the equipment is rigid, and in that case the displacement of the equipment’s pipe connections can be directly entered into the Displacement field
