Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Message Subarea: Original Author: Bentley Technical Support Group Nov 2014, AutoPIPE V8i 09.06.01.10 Problem: The following is displayed when trying to analyze a flange in the flange analysis module (Tools> Model Options> Flange Analysis): --------------------------- Bentley AutoPIPE --------------------------- The required information is missing for this flange. --------------------------- OK --------------------------- Why does the is happen and how to resolve it? Answer: With the Flange Analysis module open, confirm which Analysis Method is being used, ANSI check or other. For ANSI check Analysis Method, review the ANSI Check tab only. If Analysis Methods is ASME Section VIII Div 1, ASME Section VIII Div 2, or ASME Section III Appendix X the user must review 5 tabs of data (i.e. Load, Flange, Pipe, Bolts, and Gaskets). For each tab confirm that all the values needed are not blank or 0.00 (see Tips and Tricks feature ) Example: For Analysis Method = ASME Section VIII Div. 1, on the Load tab, it is optional for External Pressure = 0.00: However, upon further review of Pipe, Flange, and Bolt Tabs, the Allow. Stress At Amb. Temp. = 0.00 deg C: This is Wrong. There should be a value here instead of 0.00. Looking back on the Load Tab, what is the Amb temp.setting: Amb temp = -20.0 deg C. Select any one of the 3 tabs (Flange, Pipe or Bolt Tabs) and press the "Select" button in the "Select Material" column that corresponding to the specific flange row in question. The minimum Temperature Dependent property for this selected material = -6.67 deg C. Therefore the Ambient Temperature on the other tab should not be any higher than -6.67 deg C. Otherwise the value must be changed in the model. Use the following procedure to update the data accordingly: 1. Change the ambient temperature from -20 deg D to within the material allowable table values -6.67 to 898.89 deg C, re-analyze the model, and re-enter the Flange Analysis module. 2. Update the Allow. Stress at Amb Temp values by changing the Flange Material on the Flange Tab, Pipe Material on the Pipe Tab, and Bolt Material on the Bolt tab to a different value and then back to the same value. Example: on the Flange Material tab, change SA-105 to SA106-b for all rows, notice that the values in the table to the far right were updated. Once more, change the material value from SA106-b back into SA-105. Using the power if the grids update the other rows as needed. Repeat same procedure for the other 2 tabs. 3. Continue to review and update the tabs as needed. When completed return to the Analysis Tab. 4. On the Analysis Tab, check the flanges to be analyzed and press the analyze button. If all the data has been entered and refreshed the following should appear : --------------------------- Bentley AutoPIPE --------------------------- Total number of flange analyzed : 75 --------------------------- OK --------------------------- Note: Total number may be different per your analysis.
