Problem:

How does AutoPIPE calculate the allowable for ASME NB, eq 10?

Solution:

Please see the following AutoPIPE help section: 

Help > Contents> Contents Tab> Reference Information> Code Compliance Calculations> ASME BPV-III-1-NB (1972 - 2015)> Level A and B Service Limits> NB - Primary Plus Secondary Stress Intensity Range (Equation 10).

However, see AutoPIPE help section above for additional information about how Sm is calculated (hint: For ASME BPVC III Class 1, 2010 Edition and later...new feature was added "Use Avg Sm Allowable" check-box).
