Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Subarea: Original Author: Bentley Technical Support Group Item #1: Be sure to review the following AutoPIPE online help information: Help Contents Contents Tab Reference Information Code Compliance Calculations This area describes variables, equations, and methodology used by AutoPIPE to produce output reports per the code associated with the piping system database. AutoPIPE is capable of generating actual and allowable stresses for each of the applicable stress categories (depending on the current, analyzed load cases) for all codes listed below. Please Note: The Standard edition only has access to 4 ASME codes and European code EN13480 as shown in the Getting Started topic "AutoPIPE Standard vs Advanced vs Nuclear". Select the Pipig code hyperlink below for general questions on the respective code calculations. Note: additonal hyper links are added as new information is presented.

Answer: Confirm the model is considering axial force, as this option by default is turned OFF. See Tool Model Options Results "Include axial force" option Excerpt from online help: The piping codes ignore the effect of axial force for calculating stresses in the sustained and occasional categories (only bending moments are considered, see Code Compliance Calculations). This option has been provided to allow the inclusion of axial force effects. By default this option is unchecked.... See online help for more information on this option. item #3, Question: Our Project Design Specification calls for ASME II 2010 for Material and ASME III 2007 with 2008 addenda for Rules for construction of nuclear facility components. However, there is no exact selection of ASME III Code year within AutoPIPE. Please advise the appropriated setup for ASME III Nx Stress analyses with above described Code year. Answer: AutoPIPE V8i 09.06.xx.xx and lower has the following nuclear codes for selection: ASME BPV-III-1-NB (1972 - 2007) Boiler & Pressure Vessel Code, Rules for Construction of Nuclear Power Plant Components Division 1, Subsection NB, Class 1 Components (1972 + 1972 W addenda, 1974 + 1975 W addenda, 1977, 1980 + 1982 W addenda, 1983 + 1983 W addenda, 1986 + 1988 addenda, 1989, 1989 + 1989 addenda, 1992 + 1994 addenda, 1995 + 1997 addenda, 1998, 2001, 2004, and 2007) ASME BPV-III-1-NC (1972 - 2007) Boiler & Pressure Vessel Code, Rules for Construction of Nuclear Power Plant Components Division 1, Subsection NC, Class 2 Components (1972 + 1972 W addenda, 1974 + 1975 W addenda, 1977, 1980 + 1980 S addenda, 1983 + 1983 W addenda, 1986 + 1988 addenda, 1989, 1989 + 1989 addenda, 1992 + 1994 addenda, 1995 + 1997 addenda, 1998, 2001, 2001 + 2003 addenda, 2004 and 2007) ASME BPV-III-1-ND (1972 - 2007) Boiler & Pressure Vessel Code, Rules for Construction of Nuclear Power Plant Components Division 1, Subsection ND, Class 3 Components (1972 + 1972 W addenda, 1974 + 1975 W addenda, 1977, 1980 + 1980 S addenda, 1983 + 1983 W addenda, 1986 + 1988 addenda, 1989, 1989 + 1989 addenda, 1992 + 1994 addenda, 1995 + 1997 addenda, 1998, 2001, 2001 + 2003 addenda, 2004 and 2007) As you can see there is currently no 2007 + 2008 addenda edition. This enhancement has already been logged under CAE-CR-6978: "Update ASME NB NC and ND code to 2008 addenda" and will be included in a future build of the application. Please review the code as there is not much difference between 2007 release. With regards to which code to select from the Tools Model options General Piping code drop down listing, due to liability law suits Bentley TSG is not at liberty to dictate what piping code / year should be used in your model. That is for you to determine. Recommend reviewing the possibility of using ASME NB, NC, or ND piping code. Most of the material data in the libraries associated with the Nuclear Piping codes has come from ASME BPV-III. Please see the online help for details of what code year.
