The Result > Flange > Flange Check command will display the Flange Analysis dialog, enabling the user to apply several different flange analysis methods on every flange in the model. Standard flange data can be recalled from dimension and material libraries. For nonstandard (user-defined or NS) flange dimensions and material allowable stresses can be provided by the user. The Flange Analysis dialog can be used to analyze any flange in the model based on one of the following four analysis method options: 1. ASME Section VIII, Division 1, Mandatory Appendix 2, Rules for Bolted Flange Connections with Ring Type Gaskets 2. ASME Section VIII, Division 2, Section 4.16, Design Rules for Flanged Joints 3. ASME Section III, Appendix XI, Rules for Bolted Flange Connections for Class 2 and 3 Components and Class MC Vessels 4. ANSI Flange Loading Check Note: 1. See Flange Analysis Troubleshooting tips and tricks 2. See the following link for Flange Analysis Enhancements Comments, Questions, and Answers Perform an ANSI Check Flange Analysis Flange calculations only considers -ve axial force, otherwise all other force values are 0.00 Performing an ANSI flange analysis; a specific flange always Fails to be analyze, why? When Int. press ration >1.0, does this mean that the Flange failed Perform an ASME Section VIII Div 1 / 2 or Appendix XI Flange Analysis Operating Pressure field is limited to 3000 psi Determine expected leakage rates Load case combinations available to the Flange Analysis Library flange data does not seem to be correct No options are shown on the Flange / bolt Dimensions dropdown listing "Zero loads and moments": connection failed Add user defined Flange Pressure data Gasket Effective width does not match the ASME code value Flange Analysis module, why? Max Ratio = 0.00 and Notes = Fail "Consider Bolt Spacing Correction" option Calculate the Effective Dia Define Gasket thickness Warning messages: The Bolt spacing correction factor is greater than 1 because.. The Gasket Material [SPIRAL-WOUND ALLOY WITH MINERAL FIBER FILL] is not available in the GasketMaterials Table.
