Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Calculations Subarea: Original Author: Bentley Technical Support Group Comment, Questions, and Answers about ASME B31.4 code calculations in AutoPIPE Item #1: How to calculate the allowable expansion stress for ASME B31.4 Ed. 2012 in AutoPIPE? Item #2: For ASME B31.4, why are the fields "Use nominal thickness" and "Use nom. Thk. for Hoop" unchecked in AutoPIPE V8i 09.06.00.15? Item #3: Using AutoPIPE V8i 09.06.00.15, with ASME B31.4, what is the difference between the 2 settings for restrained soil analysis? Item #4: When analyzing a model per ASME B31.4 should there be a warning displayed if "Use rest. Long. Code eq" is unchecked in AutoPIPE? Item #5: How to correctly consider Von Mises (maximum distortion energy theory) in an AutoPIPE combination? Item #6: In AutoPIPE, request an option to choose Von Mises criterion or Tresca criteria since ASME B31.4-2012 admits to use both. Item #7: Why is the code allowable for ASME B31.4 - 2012 different from B31.4-2009 for Stresses Due to Sustained Loads? Item #8: In B31.4, Table 403.3.1.1, no stress is mandatory for slurry lines except Pressure stress. How it is taken care for slurry line in b31.4 and AutoPIPE?
