Hi All, Hoop stress based on ASME B31.8 shall be same along the pipeline to my understanding(PD/2t), but the code check gave the different values along the nodes. How does Caesar implement this. And does Caesar account for external pressure reduction the formula. Finally, based on latest code ASME B31.8, 2016 there is different equation for the hoop stress based on D/t ratio; so, when Caesar is implementing this. Regards, Vrk.
