Hi all,
I am doing the stress analysis for a bitumen line at temperature of 180.The line is hot oil traced all over and the ambient min temp is 5.
I have considered 21 for the installation temperature .Because the line is traced so one of our engineers is telling that we don't need the line to be analysed for the expansion between 5 and 180?
What do you think? Should we need to consider it in our work?


Thanks,
