yes I'm sure, I have the isometrics and also i verified in field, because the plant is out of operation. there is not a flexible joint because the line is at 2844 psi. i made a test just changing the temperature to 100°C and there are points with a ratio higher than 1, due to the two anchores at the ends, if I take off one anchor the stresses diminish. I also changed the rigid anchores for flexible and I got the same results. how do you simulate a pipe anchored by the ends at high temperature with values of stresses out of the code, even higher that the minimum yield, which mean the pipe could be warped but in field it's perfect Thank you
