In the example above sent (see. TEST.zip) we got some doubts about the criteria used by caesar II 5.0 of buried pipe. In our case we are avaluating a long straigth pipe where its suposed there aren´t transversal displacements that could generate overstresses due to thermal expansion along the pipe.

Why do you say that 121°C is a high value for a buried pipe? under wich criteria do you say that?

If we evaluate the same case in CAESAR II 4.5, the system doesn´t fail.

Thank you
