Dear all, Dave, Richard, MoverZ, Edward and anyone else that can contribute with my cause.
First at all, I am in trouble, I work for a small company where I do not have a senior engineer who I can ask about all my doubts and we seldom do these stress analysis on Caesar, said this lets talk about the ISSUE.
We need to connect a cylindrical heater with helical coil 6 nps pipe and up fired burner [4] and, off course, we need to run a stress analysis on these new lines. I Have read some previous threads about the issue [1] [2], that is why I feel pretty worried right now, becouse of the complexity of the model.
The Vendor has given to me a draw with loads and thermal growth[3]. The easy way is just add the longitudinal displacement to the pipe nozzle and run the analysis but if you look a little bit better those fined tubes in the convectión section are not tied to anything just supported on ferrules, so the nozzle will definitelly be able to move inside the convection box regardless the thermal growth. I am just starting with this analysis but I would really appreciate if you could give me some tips, advice or guidance, I do not want to make my own refinery disaster, I am wondering if I could up load some files as soon as I run them, One more time Thanks, hope you can comment and discuss on these thread.
