"User entered value: on element 10 to 20 the allowable stresses are not specified properly, the required pipe thickness can not be computed"
Pipe specs are: 8" Sch 80 API 5L grade X52. Code is ASME B31.11 "Allowable Stress" box is checked.
I have already entered the schedule for the pipe in W/sch input and CII correctly put value of 0.5 inch. What is this warning about?
