I have a 42 inch pipe lined with cement (service:salty water); code:ASME B.31.3. I have to questions. 1)Is it correct to carry out the stress analysis in Caesar. My question is due to SIF's used by CAESAR are based on Table D-300 (B31.3) and its validity has been demostrated for D/t less or equal than 100. I have D/t greater than 100. 2)I read B31.3 chapters related to Piping Lined with non-metals in order to know how to perform the analysis (due to differences in properties between CS pipe and the liner, but I do not find a clear answer. Could anyone help me?
