In order to have an equipment check for turbines, CAESAR II requires us to enter DX, DY & DZ (distances between turbine nozzles and the resolution point). Regarding how we can find the location of the resolution point, NEMA SM23 doesn’t provide any helpful guideline. Finally, in a booklet, I...
Because of the snubbers malfunctions and time consuming and costly inspections required for them, the use of “seismic stops” has been taken into account to reduce the piping vibrations . These stops usually have 3-4 centimeter of gaps and are designed in a way to be as effective as snubbers in...
Hi everybody;
When a dummy leg is attached to an elbow in a piping system, C2 considers its length in flexibility calculations, so the proper length of dummy support matters. I want to share my understanding of this issue with you and know if you guys agree with me or not.
1- If the dummy...
Regarding the second question (nozzle load evaluation with seismic loads), I think it depends on your project specifications. For example for the project I'm currently working for, it's mentioned in the relevant specs that occasional loads should also be considered for load evaluating. I suggest...
Hello everyone;
In a CAESAR II model I decided to add a dummy leg in the model. In my first try everything was OK and there was no overload at the equipment nozzles. But when I changed the direction of dummy leg, did this out of curiosity, I understood the dummy is not sustaining any load and...
