Course details

This course provides a focused understanding of solid mechanics principles and their practical application in the design and analysis of piping systems as governed by the ASME B31.3 Process Piping Code and related B31 standards. Participants will explore how fundamental concepts such as stress, strain, elasticity, plasticity, bending, torsion, and failure theories underpin piping design rules, allowable stresses, and design margins. The program emphasizes bridging theory with practical code application, helping engineers interpret code equations, evaluate stresses in piping components, and apply engineering judgment to ensure safe and reliable designs. Case studies and practical examples illustrate how solid mechanics directly informs the modeling, analysis, and compliance of piping systems under real-world loading conditions.

Questions and Answers

Q: You're under audit and reviewing a stress report for a hot condensate line. The analyst treated thermal expansion stress as primary and limited it to Sh. You're googling "B31.3 thermal expansion stress treated as displacement controlled" while deciding whether this passes. Under ASME B31.3 philosophy, what is the real non-compliance here?

A: A: That's how wind or seismic gets treated. Expansion doesn't belong in that bucket. B: Expansion is displacement‑controlled; limiting it to Sh forces fake restraints and masks flexibility problems. C: Peak stress logic fits fatigue hot spots, not global thermal growth. D: Corrosion allowance affects section properties, not how the stress category is classified.

Q: Your lead asks you to sanity‑check a hand calc and you search "B31.3 sustained longitudinal stress calculation example". A carbon steel line (A106 Gr B) has sustained longitudinal stress from weight and pressure of 95 MPa at 250 °C. Sh at this temperature is 138 MPa. Is it acceptable?

Q: You're reviewing a GA and piping isometric and googling "pipe stress model mismatch with as-built supports". The isometric shows a rigid shoe on a beam, but site photos show a constant spring. Why does this matter for B31 compliance?

Q: A thin-wall carbon steel line shows ovalisation and inward buckling after shutdown. You're searching "external pressure collapse thin wall piping". Which load case is most consistent with this failure?

Q: You're checking a flexibility analysis and googling "B31.3 allowable stress range SA calculation". For A106 Gr B, Sc = 138 MPa, Sh = 120 MPa, f = 1.0. What is SA?

Q: A flange at a pump discharge keeps leaking after gasket changes. Stress report shows low code stresses. You're googling "flange leakage due to pipe rotation B31". What's the most likely root cause?

Q: You're comparing B31.3 and B31.4 and searching "difference between B31.3 and B31.4 allowable stress philosophy". Why does B31.3 limit sustained stress to Sh, while B31.4 uses different factors?

Q: On a stress isometric you see a fabricated tee with no reinforcement pad, NPS 12 run and NPS 6 branch. You're googling "stress intensification factor unreinforced fabricated tee". What should you be most worried about?

Q: You're validating wall thickness and searching "nominal vs effective wall thickness pipe stress". A Schedule 40 pipe has nominal 9.27 mm wall, mill tolerance −12.5%, and corrosion allowance 3 mm. What thickness should be used in stress calcs?

Q: A hot line with frequent start‑ups develops progressive axial distortion over months. You're googling "thermal ratcheting piping sustained and cyclic loads". What mechanism best fits?
