Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Enhancement Subarea: Original Author: Bentley Technical Support Group Note: if an enhancement has not been added to the program, log an Service request for that enhancement. The more requests logged per an enhancement, the quicker the CAE development team will add that feature to the program. The following enhancements have already been requested: TFS-E305976: Add color plot for Line Number Description: Add color plot for Line Number Corrected Version: TBD TFS-E262256: Report Max (+ & -) of the Global forces and moments about anchor points Description: When modeling : Anchor-Pipe-Anchor-Pipe-Anchor. Running a static seismic cancels the moments on the mid-anchor because of its symmetry. A designer who is not attentive may only use the M = 0 from the "Restraint Reaction" page, and not think of checking the moment from the "Global" page. It is more difficult to catch of course if the model is not symmetrical, and prints the difference of element moments from each side instead of the sum. Suggest reporting the Max (+ & -) of the Global forces and moments about anchor points Corrected Version: TBD TFS-E239855: Generate detailed hanger listing report in excel to help purchase and installation of pipe support Description: Generate detailed hanger listing report in excel to help purchase and installation of pipe support. This report to list following attributes per support Corrected Version: TBD TFS-E237988: Report calculated hydrotest pressure in model input listing Description : Users should be able to view the hydrotest pressure for the model easily for checking of the model purposes. Corrected Version: TBD TFS-E218330: Add Center of Gravity Offsets for Manual Valve Actuators Description: Currently, regardless of the offsets of the manual valve actuator, AutoPIPE considers the center of gravity to be at the valve mid-point. Corrected Version: TBD TFS-D181952: Tees with different material across tee legs may report inconsistent allowable values Description: Inconsistent allowable values may be reported for a tee that has different pipe materials across different legs. This applies to ASME NB and JSME Class2 Piping codes, where tee moment summation is applied for calculating stress values for the tee component. Based on the arrangement of the pipe materials for different tee legs, the allowable stress value for certain tee legs may be reported higher than the actual allowable value for that leg’s material which may lead to un-conservative results. To illustrate the defect the following scenario can be considered: Step 1: Create a new class 1 model with Edition set as 2007 Step 2: Create a pipe ID M_HIGH, with 12” nominal diameter and material selected as SA106C Step 3: When prompted for Design Pres & Temp, enter Design Temperature as 200 deg F Step 4: Insert an anchor in the model at A00 and invoke Tee Point dialog (Insert > Tee) Step 5: On the Tee Point dialog, enter 10 feet in DX direction, select “Pipe data identifier” as M_HIGH, “Tee component” as Tee, “From point orientation” as 1-Header and Type of tee as Welding and press OK Step 6: Click on the small blue arrow at point A01 pointing in the same direction as the header and invoke “Insert > Run” Step 7: On the Run Point dialog, enter length as +10 in the DX direction with Pipe data identifier selected as M_HIGH and press OK Step 8: Now select the last remaining arrow pointing perpendicular to the Tee header and invoke “Insert > Run” Step 9: On the Run Point dialog, enter length as 10 feet, enter 10 feet in the DZ direction and overwrite Pipe data identifier with M_LOW and press OK Step 10: On the Pipe Properties dialog that appears, enter 12” nominal diameter and select material as SA106A Step 11: Analyze the model and take out Preliminary Stress report for the model A value of 34,950 psi (1.5*Sm = 1.5*23,300) is reported as Equation 9 Allowable for both the header and branch of tee point A01. Notice that the lower value of Design Sm of 16,000 (resulting in 1.5*Sm = 24,000) for Pipe ID M_LOW having pipe material SA106A is not taken into consideration when calculating the allowable value. For JSME PPC piping code, this issue is only observed when the tee header is constructed of two different materials having different hot allowable Sh values i.e. two different materials used along the two legs of the header pipe. The following considerations are provided to assist in your evaluation of the potential impact of this defect on the results: 1. Evaluate whether this defect has affected any existing models by considering the criteria below: a. Was the model created in program version 9.1.0 or later? b. Was the piping code for the model set to any one of the following two piping codes? i. ASME NB Nuclear “1974 + 1975 W addenda” edition or later ii. JSME S NC1 Class 2-PPC 2005 edition or later c. Was there a tee in the model having different material used along different tee legs? A 'No' to one or more of the above criteria means that this defect does not affect the model’s results. No further consideration for this model is necessary. 2. Otherwise, the following mitigating conditions should be considered: a. For JSME piping code, this defect is only observed is there is a change in material along the tee header. Having different material for Tee Header and Branch of the tee component reports correct allowable values. b. For JSME piping code, this issue is not observed if the “Apply tee summation” result model option is unchecked c. For ASME NB piping code, if there is no change in material along the tee header then the allowable values are always calculated based on the tee header material Important Note: ASME NB code does not clearly define whether the allowable value for a tee component shall be calculated using the minimum Stress intensity and yield strength from Header and Branch of a tee. However, response from ASME to an interpretation request from AutoPIPE team tends to suggest that the conservative approach of taking the minimum stress intensity / yield strength from the Tee header and branch is allowed / favored by the committee. Please see the response from the ASME committee to the question below: Question: If a branch connection is constructed of different material specification for Run and Branch does the code prohibit using the most limiting allowable stress intensity value for equation 9 and equation 10? Answer: No Avoidance: Manually enter the most conservative Hot Allowable value for affected tee component legs under Pres/Temp/PipeID tab of Review Component Data grid. Corrected Version: 09.06.02.06 TFS-E148629: Report Viewer to be the active Window when opened Description: After creating an output report the active window should become the Report Viewer instead of the program window. Steps to repeat: 1. With any model opened, create an output report 2. After the Report Viewer is automatically display, use the mouse wheel or press the keyboard PgDN Key / Cntl+ Print. The program Window reacts, sending the Report Viewer Window to the background behind the program window. Request that the Report Viewer window become the active window when opened Corrected Version: TBD TFS-E130548: Add option to view beam displacements in results grids. Description: Add option to view beam displacements in results grids. This could be very useful when working with civil structure departments in reporting thermal displacements. Reporting pipe displacements is excessive and leads to overdesigning of support structures and foundations. Corrected Version: TBD TFS-E108571: Add option to envelope loads for supports at the same node point or beam Description : See Forum Post by Ross Sinclair on Thu, Jun 12 2014 12:43 AM Corrected Version: TBD TFS-E72841: Include an ability to model local membrane effects using shell elements for pipe supports Corrected Version : TBD CAE- CR-8732: Add total length of pipe to Extended Component Data Listing report Description: Add feature to display total pipe length for each PIPE ID and grand total pipe length data at the end of the Extended Data Listing report CAE-CR-992: Display displacements results in the local coordinate system Description: Display displacements in the local coordinate system. Corrected Version : TBD Avoidance: Using the results grids in conjunction with MS Excel it is possible to calculate the global / Local displacement between node points.
