Problem:

For ASME NCD 2021, where is NCD-3653.2 Equation 11 reported?

The help contains a dedicated Equation 11 page, but Equation 11 does not appear in Load Combinations, Stress Summary, or Output Reports.

Could you please help explain where to find the Equation 11 results in AutoPIPE?

Solution:

ASME NCD equation 11 refers to "Sustained Loads & Thermal Expansion Requirement" provided under section NCD-3653.2. You are correct in stating this equation is not visible in AutoPIPE's Stress Summary dialog or Combinations dialog. 

Question:

Does AutoPIPE calculate results for Eq. 11?

If yes, where are the results for Eq. 11 printed / shown?

Answer: 

Yes AutoPIPE calculates Eq11. its configuration is controlled by the definition of the other equations 9 and 10a.  Results for Eq 11, will appear in 2 locations:

(1) Printed in the output code compliant stress summary sub-report. 

(2) And, available in the interactive plot, shown below.
