many thanks to everyone! thanks for pointing out that I should use 31.8 instead of 31.4...that's very helpful!! For liquid pipeline, effective stress design factor can be 0.9. I still don't find the factor for gas pipeline though, but it will definetely smaller than 0.9 to my understanding. My...
Thanks ahead for everyone's reply!
More details here: actually we're going to construct the railroad over the existing uncased gas pipeline, we will have ~10ft embankment over the existing ground and also over the existing pipe. We're trying to perform the stress analysis for the new...
Hi everyone, I'm working on aa pipeline stress analysis crossing the railway and I'm referring to API RP 1102 (2017) and ASME B31.4 -2006.
Starting from API RP 1102
My pipe can pass the "allowable stress check“ with 0.72SMYS. Let's call F1=0.72
However, it failed for the "total effective stress...
