Comments, Questions, and Answers:
Note:
- See "Piping Code Calculations - AutoPIPE" wiki for more Code specific calculations and reporting errors
- AutoPIPE does not print Code stress results when last components modeled are element (ex. flexible joint, nozzle element, etc..) and anchor. insert a short pipe run between the elements to see code stress results.
- What is the meaning of:
- Why are Code stress results different after adding an extra node point to pipe run / bend?
- Hoop related questions
- Stresses results for gravity load-case only
- Thermal loading does not seem to be applied in the axial direction, why?
- SIF questions and answers
- Stress results greater for a slower wind speed than a higher wind speed
- "Max Range {TR]" does not match the indicated combination value or any of the other Expansion combination values, why?
- What to do when dynamic Response Spectrum exceeds a code allowable?
- Why are there no normal Code Combination results, only HDPE combinations?
- Output report / Results grids, Code Stress results are completely blank , why?
- Considering that E2=-E1 why are the combinations GRTP2-E1 & GRTP2+E2 results not the same?
- Appear to be using the valve material when computing the allowable stresses
- What physical properties (OD and thickness) are used at welded elbows to calculate the Indices, Stiffness, Flexibility, Section Modulus, and Pressure Stiffness using the ASME NB code?
- Over stress due to Harmonic loading?
- Over stress due to Hydrotest load-case?
- Results for a combination subtracting dynamic load cases (ex. GRT1P1 +U1 -S1 -R1) are higher than when adding the same dynamic load cases (ex. GRT1P1 +U1 +S1 +R1)
- Would code stress results be the same regardless of which piping code was used
- Bending stress analysis results does not match hand calculations
- Time History Results on symmetric model does not match
