WebNote that longitudinal stresses are 50% of the hoop stresses and therefore they rarely govern the design. This is the reason ASME Section I does not even require evaluating this stress. ASME Section VIII Div. 1 requires estimating the vessel thickness based on both stresses, and choosing the largest of the two values.
