The following is based on the following AutoPIPE's help section: Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches> Frames> Frames: Pipe Rack Modeling Examples Frames: Pipe Rack Modeling Examples Frame structures are commonly used to support piping systems. In most cases, the structure is assumed to be much stiffer than the piping itself and can be modeled simply as a rigid support. However, AutoPIPE also allows a supporting frame structure, such as a pipe rack, to be included in the system model. The following models depict a system of parallel pipe runs (shown in the figure) which are supported by a pipe rack structure. The pipe-frame connection type varies with each model. The piping system is usually defined first as this simplifies the modeling of the frame that supports the pipes. Three methods for modeling pipe racks are provided below: Pipe Rack (Method 1): Each piping point is connected to a corresponding beam point using a two-point support (tie/link). Pipe Rack (Method 2): A pre-defined directional support at each piping point can be connected to a single beam point. This model takes advantage of the fact that a V-stop always restricts the movement of a point in the vertical direction irrespective of the location of the Connected to point. This simplifies the modeling of the frame itself as definition of all connection points are not necessary. However, all of the support reactions are transferred to the one beam point rather than their actual locations (directly beneath each piping point). Pipe Rack (Method 3): Each piping point is connected directly to a corresponding beam point. This model represents a rigid connection between the pipe and beam member. Comments, Questions, and Answers on Frames: Pipe Rack Modeling Examples: 1. What modeling method and support type should be used for pipe U-bolted on a rigid beam? Answer: First ask yourself what type of AutoPIPE support(s) are required to mimic the actual support. AutoPIPE allows the user to place one or more supports at a node point to mimic an actual support. How is the pipe restrained / allowed to move in this image above? 1. Pipe cannot move down, because of resting on beam that is rigidly supported. 2. Pipe cannot move laterally because of U-bolt (assume no gap). 3. Pipe cannot move Upward because of U-bolt (assume no gap). 4. Pipe can move axially through the support with some amount of friction. Open the Support dialog and press the HELP button, the following grid of information will be displayed for reference: Bearing Direction refers to what axis a support's stiffness will act in. Example, V-stop bearing direction is Vertical only. Therefore regardless of a V-stop orientation, it would only resist vertical movement of the pipe node point because the bearing direction is what, correct: Vertical only . In this example above, what options are available that meet all 4 criteria for bearing directions: Option #1, Use 2 supports: 1 - V-stop and 1 - Incline, the V-stop will resits any vertical movements while the incline can be set to resist any lateral movement. Option #2, Use 2 Supports: 1 - incline on the vertical axis and 1 - incline on the horizontal lateral axis. Option #3: Use 1 support: guide. Option #4: Use 2 supports: 1 - tie/link on the vertical axis and 1 - incline on the horizontal lateral axis. Q. What modeling method and support options should be used? A. There are 3 choices Choice #1: use Pipe Rack (Method 1), however this will limit your support option to only #4. Choice #2: use Pipe Rack (Method 2), all of the support options would be suitable, however suggest option #3 as it only has a single support Choice #3 : model only the support using support option #1, #2, or #3 without modeling the frame work. 2. What modeling method and support type should be used for pipe resting on a rigid beam? Answer: Using the same philosophy as before, How is the pipe restrained / allowed to move in this image above? 1. Pipe cannot move down, because of resting on beam that is rigidly supported. 2. Pipe can move laterally because of U-bolt (assume no gap). 3. Pipe can move Upward because of U-bolt (assume no gap). 4. Pipe can move axially through the support with some amount of friction. In this example above, what options are available that meet all 4 criteria for bearing directions: Option #1, Use 1 supports: 1 - V-stop Option #2, Use 1 Supports: 1 - incline on the vertical axis Option #3: Use 1 supports: 1 - tie/link on the vertical axis There are 2 choices Choice #1: use Pipe Rack (Method 1) with support options #3. Choice #2: use Pipe Rack (Method 2), all of the support options would be suitable, however suggest option #1 Choice #3 : model only the support using support option #1 or #2 , without modeling the frame work.

I had run an analysis on a buried GRE pipe using ISO 14692 and found that the allowable stress for the displacement (thermal expansion) is 0. After going through the help file on the allowable stress for ISO 14692, I had found the following: "Note: In case of allowable value being zero for either Hoop or Axial (i.e. as in case of expansion category, the allowable values are set to zero), AutoPIPE will report the Max. stress (or Combined Stress) based on the maximum value from Hoop combined stress and Axial stresses combined stress." I have a few of questions regarding this note: 1. What is the reason for setting the allowable stress for expansion to 0? 2. How is the stress caused by thermal expansion calculated? By taking either the hoop stress or axial stress? 3. How to verify whether the pipe will fail at the max displacement stress reported? Thank you.

Sign up for Events, Webinars, Seminars, Conferences, and Learning here. 1. AutoPIPE Editions: AutoPIPE is available in the following editions: Standard, Advanced (PLUS), and Nuclear. The following AutoPIPE help page provides a table which illustrates the different capabilities of these 3 AutoPIPE editions: Help > Contents> Contents Tab> Bentley AutoPIPE> Getting Started> AutoPIPE V8i Standard vs Advanced vs Nuclear. Be sure to review the information links at the bottom of this page: See Also: Limits of Standard vs Advanced vs Nuclear Piping Codes by Program Editions Note: 1. If a model was created by an AutoPIPE edition (i.e. Nuclear) that used feature specific to that editions (i.e Piping code = ASME NB) and was later opened by a version that did not have the same capabilities. Some settings would be automatically changed and would need to be manually changed by the user. Review the following for a complete list of changes made by the program or required before analyzing the model: 1. systemname.CHK file - this file is automatically displayed by AutoPIPE Report viewer after the model has been opened. Or, see the current model folder location. This file that can be opened with any word editing software (i.e. MS Word, NotePAD, etc..) 2. Tools> Model Consistency Check report. reduce the number of errors and warnings to as few as possible. 3. Tools> Design Check, reduce the number of errors and warnings to as few as possible. 2. If a model was created in a lower edition (ex. Standard) and opened in a higher AutoPIPE edition (ex. Advanced). Nothing will changed in the model as each higher level of edition contains all the features of the lower level(s). Example, AutoPIPE Standard model with 5 Static earthquake cases was opened in AutoPIPE Advanced or Nuclear. No changes are made to the model as both Advanced and Nuclear edition supports up to 10 static earthquake cases. To reinforce Note #1, if an Advanced model with 10 static earthquake cases was opened in a AutoPIPE Standard, static earthquake cases 6, 7, 8, 9, & 10 would be automatically deleted from the model. 3. See the following for a complete list of AutoPIPE versions released to the public: Current version: (verify your version and UPDATE) AutoPIPE CONNECT 11.00.00.22 released Feb 2017 AutoPIPE CONNECT 10.01.00.05, (update 10.01.00.08, 10.01.00.09*).

Opening a file with AutoPIPE: Any version of AutoPIPE can and will open any DAT file created by the program. However, there are rules: Rule #1: Only open a model DAT file created by the current version or higher (Example: if a model DAT file was crated in AutoPIPE 2004 v. 8.6, that file can be safely opened in v8.6 or higher version number (ex. V9.4). Rule #2: DO NOT open a model created by a newer version in an older version without using the File> Save AS command in the new version. (Example: if using AutoPIPE V8i 9.4.1.5, and the model was save using the File> Save commend, DO NOT open it in any version of the program lower than v.9.4.1.5. The correct procedure; with the model open in the higher version, use File> Save As command> Select the version that will open the model i.e. 9.0; this will automatically append “_V90” to the file name alerting you to the fact the file was correctly saved from a newer release of the program to an older file structure. Rule #3: If Rule #2 was broken, when opening a model created by a newer (ex.V9.4) version in an older version (ex. V9.0) the following will appear: --------------------------- Confirm --------------------------- Model was first created in : 09.00.00.05 Model was last modified in : 09.04.01.05 Current product version : 09.00.00.08 The model you are about to open was last modified in a newer version of the product and may not be compatible with the current version. You should contact Bentley`s technical support for compatibility information on this model before opening it. Saving or analyzing the model in the current version may result in the loss or corruption of the model data. Do you want to continue with opening this model? --------------------------- Yes No Cancel --------------------------- Selecting “Yes” button WILL corrupt the model the very moment the model is displayed on the screen. There is no fixing a corrupted model. Selecting “No” button will close the model without opening (recommend) Selecting “Cancel” button stops the open command. Options: (choose an option below) #1: Download and install the correct version of AutoPIPE required to open a given model as noted by message above (ex. 09.04.01.05 or higher). #2: Some one with a version equal or higher than mentioned by message could open the model and use the File> Save As feature to save back to a version that you are able to open. #3: Exception to Rule #3, typically model can be opened by same family versions , (i.e same first 2 numbers), but still recommend using the File> Save-as command from the higher version. (Example: model was created in 9.1. 1.5, not recommended, but can open with 9.1. 1.2. The warning above will still appear but is acceptable. Notes: 1. Once a file is corrupted, typically there is no method to repair it. However, the CAE development team has had some success in fixing corrupted models.

General steps for reviewing a model: 1. Open the model in AutoPIPE 2. Press Tools> Model Consistency Check. a report will appear, try and reduce the number of warnings to 0. The goal is to see the following message when using this command: --------------------------- Note --------------------------- N723-25: No error detected during consistency check --------------------------- OK --------------------------- However there are some modeling situations that will always display a warning. Again, try and keep these warnings to the bare minimum. Note: See WIKI here to known warning meaning and fixes. 3. Press Tools> Design Check. a report will appear, try and reduce the number of warnings to 0. The goal is to see the following message when using this command: --------------------------- Note --------------------------- N2182-22: No errors detected during design check. --------------------------- OK --------------------------- However there are some modeling situations that will always display a warning. Again, try and keep these warnings to the bare minimum. 4. Use the power of the Input grids to review the model a. With AutoPIPE open, at any time select Tools> Settings> Grids> suggest that "Show input grid tabs with no data" be disabled (unchecked). b. Open a model, and make the model input grids visible c. Select the left most tab (i.e. Press/Temp/PipeID) d. Just scan the data looking for inconsistencies e. Move to the next tab on the right, Pipe Properties, and perform the same function of scanning the data. If you had taken the training class you would already know that any column can be reordered by increasing/decreasing values by double clicking on the column header. Spot check the pipe id in the model by selecting a Pipe property row. This will highlight only this PipeID in the model Red, clearly showing where it is being used. f. Continue with each tab in the input grid that has data, just scan the information looking for similarities or inconsistencies. 5. Use the View> Show command Under View> Show there are a variety of commands to display model data in different ways. Recommend reviewing all, but at a minimum use: Show Operating Temperature Show Operating Pressure Show Pipe Properties Show Hydrodynamic Data Show Soil Properties Show Weight Show Concentrated Forces Show Imposed Displacements Show Thermal Anchor Movements and any other show / view command that are interesting. 6. Confirm segments are connected together. AutoPIPE 9.4 and higher has a command to select connected groups of pipe segments (Select> Connected segments>). This is a great tool to confirm if all segments are connected or if a model has a separate piping system / group when everything was thought to be connected. 7. Check to see if unintentional items are hidden from view. a. View> Hide components b. Segment tab of the input grid, confirm all segments have "Show" checked ON (unless intentionally hiding a segment) c. May need to change from Solid model View to Wire Frame or Single line mode to see if an item was hidden. 8. Before performing an analysis, delete all unused items: Select Delete> Delete Unused Pipe ID, Delete Unused Section ID Delete Unused Soil ID 9. Before performing an analysis, review all model settings under Tools> Model Options> typical: General Edit Results and others as needed 10. Static Analysis sets: Select Load> Static Analysis Sets> review each analysis set is correctly set up. 11. Dynamic Analysis: Select Load> Dynamic Analysis> review each tab to be sure each is correctly configured. 12. Analyze the model: Select Analyze> Analyze All. 13. Review combinations: Select Tools> Combinations> check both code and non-code combinations. In addition, review Combination Option settings 14. Review the data: A. Create an output report with all the sub reports checked ON. Scan the output report looking for points that have failed code stress requirements (marked with a "**" at the end of the row). In addition, pay special attention to reviewing the following section in greater detail: i. Model listing ii. Stress Summary iii. Result summary iv. Analysis summary 15. Using the powerful features of the Results grids to interpret the data. Example: A. on the Code stress tab, shut off all combinations except for a selected combination, thus seeing how each combination has stressed the model in a color plot of Stress per combination. B. If a specific combination is causing a model to fail at a point, review each individual load case of the combination to see what is the major contributing factor (caution: the model may have concentrated forces associated with a specific load case causing the failure, review the entire model construction to understand how this may affect your results). 16. Animate load cases In order to understand stresses in a piping system, it is beneficial to understand how the system is responding to different loading conditions. Using AutoPIPE, the user can actually watch an overly exaggerated animation of the system's displacements per load case thus helping to understand why a particular section of a seemingly symmetrical model is under more stress than another part of the piping system. Command: Results> Displacements or Mode Shapes> Enable "Animate load case " option. 17. At the end before closing the model a. compact the model, Tools> Model compaction b. archive the model, File> Model Management> Save Archive Conclusion: If all the steps above are completed, AutoPIPE will analyze the system with the appropriate calculations based on the model settings, applied load, and piping arrangement per the Code / Non-code combinations created within the model. AutoPIPE's output reports includes but are not limited to the following: Pipe displacements Pipe forces and moments Beam displacements Beam forces and moments Anchor forces Support forces Note: See the following AutoPIPE Help location to explains how to interpret these results. (eg, +/- Force, local pipe direction, etc..) Help > Contents> Contents Tab> Reference Information> Results Interpretations> select document, (ex: Pipe Forces and Moments) 5. No results in output report (blank) Please follow these instructions: 1. Start AutoPIPE. 2. Open a model 3. Analyze the model 4. Select Results> output report>UNCHECK (turn off) both: ____"Limit results to highlighted points" ____"Apply Filter Criteria (Result/Filter)" Check ON: all options but above 2 items. Press OK button. 5. Report should be displayed for review. If report is still blank, select Loads> Static Analysis sets> confirm 1 or more analysis sets are set to be analyzed with at least one load case in each set enabled (checked ON). In addition, under Tools> Combinations> code & non-code comb. tab, confirm load case combinations are being generated and have "Print" option enabled (checked ON). Repeat above steps 1-5. For additional information, see WIKI here . 6. Files used by AutoPIPE: A number of permanent and temporary files may be produced while working in AutoPIPE.

Applies To Product(s): AutoPIPE Version(s): ALL Environment: N/A Area: Results Original Author: Bentley Technical Support Group Date Logged & Current Version Sept. 2015 09.06.02.06 Problem: Why are the displacement results so different for a single load case (ex. T1) when a single support has been added to the piping in AutoPIPE? Example: Model #1, no support, the thermal movement at A05 is : Notice the thermal movement at A01 - A05 is exactly the same. Now, add a support to A02, Vstop with gap above, now the results from T1 are significant different with the new support but still no restraint above to prevent movement of the pipe up. Can please explain why? Solution: In order to consider Gap / Friction / Soil properties in a model it must be analyzed using a Non-linear Analysis. This type of analysis uses load sequencing. The load sequence always starts with the Gravity load case (GR) being applied first. After the model has been displaced per the gravity (GR) load case, based on piping arrangement and restraints, the next load case defined in the sequence (ex. T1) is applied to the already distorted piping. Again, after the model has been displaced by the 2nd load case (ex. T1), then next load case in the defined sequence is applied (ex., P1), and continues until all load cases defined in the sequence have been applied to the model. When reviewing results it is always best to review the operating conditions (ex. Grt1, GrT1P1, etc.. ) and not the individual load case (Gr, T1, P1). The individual load cases should only be considered when trying to understand the major contributors to a given operating condition. With regards to the example above, in the segment with no support, there are no non-linear elements and thus the results for that segment should not be any different from a linear analysis, and the principle of super position can be applied. In this particular example, the initial state for analyzing T1 is GR. Owing to the configuration of this model, when the thermal load is applied there is a pivoting effect of the model at node A02 where the V-stop is applied. For the support to lift off from A02 under T1, it will need to overcome the load applied at A02 due to gravity. As the thermal loading is not enough to counter the effects of gravity, it instead pivots about the V-stop at A02. So the profile that is being displayed for T1 is a correct representation of the change or delta that T1 can cause to the model, when the initial state is gravity. This displacement profile is plotted against the un-deformed shape of the pipe, which may cause the confusion in understanding the results. Again, results for intermediate load cases in a load sequence like T1 may be a good tool to understand the contribution of a certain load case, however, the results of a single load case other than gravity (like T1, which is a change or a delta caused by T1 to the state of the model set by GR) on its own may not be apparently meaningful and can cause confusion.

Hello When I export the model to Autocad DXF I see that the valve symbol is not centered between the flanges. There is any solution at this problem? Regards, Ivan

Applies To Product(s): AutoPIPE, Version(s): ALL Environment: N/A Area: Modeling Original Author: Bentley Technical Support Group Problem: What are some typical modeling approaches for Victaulic Fittings? Solution: Victaulic coupling come in two types, rigid and flexible. The rigid coupling rigidly connects components / pipe together, while the flexible coupling allows both axial and angular movements within limits The Bentley CAE development team has developed methods of modeling Victaulic fittings using Bentley's AutoPIPE stress analysis program. Model Rigid Coupling The Rigid Victaulic Coupling is easier to model using one of the following techniques: Method #1: Model Rigid coupling as a Flange component Model coupling using regular flanges with socket or threaded connection (SIF between 2.1 and 2.3). You would need to enter the proper flange weight equal to that of the coupling. Note: modeling the coupling as a flange would cause connected bends SIF and flexibility to decrease since flanges prevent bend ovalling. Couplings will not have same effect as flanges on bends, so you may model couplings near bends as added weights with user SIF (Insert > Xtra Data > Joint Type and User SIF). Method #2: Model Rigid coupling as a Flexible Joint component Model coupling using flexible joint component. The Flexible Joint component allows the user to specify rigid axial, shear, and bending stiffnesses. However, also allows the user to specify a smaller more realistic torsional stiffness. Note: recommend weight to be equal to that of a Victaulic coupling, and Pressure Area should be set to 0.00 to avoid added pressure thrust component to the system. Model Flexible Coupling The bases of these modeling approaches was presented in a published article; "Flexible Coupling: modeling of bi-linear moment rotation relationships in AutoPIPE" by Nasir Zulfiqar (see attachment, Flexible Coupling_Nasir Zulfiqar.pdf ) The flexible coupling model is more complicated and involves modeling axial and angular flexibility. The use of a flexible joint element is recommended. The shear stiffness’s of the joint can be set to rigid and the torsion and bending stiffness’s estimated. The axial and bending flexibility is modeled using 4 rigid spider beams on each end of the flexible joint and these are connected using 4 tie-link supports with gaps. This model is similar to flexible joints model with tie rods. The determination of the stiffness and gap settings for the 4 tie-link supports is somewhat involved and is explained a little better in the articles mentioned on this WIKI page: a. Flexible Coupling_Nasir Zulfiqar.pdf b. Modeling Victaulic Flexible coupling Method-2_Rev 01.pdf Note: modeling every flexible coupling in a model (say 10 or more flexible couplings) could be a cause of nonlinear convergence issues. Method #1: Model Flexible coupling using Tie-links, rigid frame members and a Flexible Joint The 1st method has the following attributes: Captures the rotational gapped movement Captures axial gapped movement Gravity load is transferred across the joint Pressure thrust automatically calculated on Anchors with axial expansion joint No weights will be considered for the rigid frames, as the weight of the coupling has been defined by the expansion joint Bentley visited Victaulic in 1998 and gave a presentation on the use of AutoPIPE to model Victaulic couplings. The AutoPIPE model for a Victaulic coupling is based on using tie-links, rigid frame members and a flexible joint. The orientation of the frame members and tie-links can be in any direction including relative to the local pipe cords and resulting model gives a bi-linear spring rate action where the gaps on the tie-links can be set to simulate a limit on angular rotation before the spring rate of the tie-link becomes active. Discussions with the Victaulic people felt this modeling approach reasonable but the only problem was the lack of bending stiffness data available at that time for Victaulic joints. Bentley cannot provide the exact stiffness values to be used, recommend contacting Victaulic Engineering Manager. Since Victaulic does not publish stiffness data in their literature, the CAE development team approximated all the values used when developing the modeling approach. Basic type of construction: 1. Insert a flexible joint with information gathered from Victaulic's catalog / personnel. 2. On each side of the flexible joint insert 4 rigid beam members (Up, Down, Left, & Right) 3. Connect the far ends of coinciding beam member together with a tie-link support. Method #2: Model Flexible coupling referring to attached document procedure The 2nd method has the following attributes Similar methodology as Method 1 Does not have the limitations of Method 1 of having to define a spring stiffness to obtain the exact moments and rotations at the center of the flexible joint Please read the attached document ( Modeling Victaulic Flexible coupling Method-2_Rev 01.pdf ) for complete information on this method of modeling a Victaulic fitting. Basic type of construction: Similar methodology as Method #1, but with different values based on coupling geometry and movement. Example Model: Please see the attached Victaulic2.DAT model.

Applies To Product(s): AutoPIPE Version(s): ALL Environment: N/A Area: Modeling Original Author: Bentley Technical Support Group Date Logged & Current Version Aug. 2015 09.06.02.06 Problem: How to model a Viscous Damper in AutoPIPE? Solution: Dampers Following extract from AutoPIPE online help: When Damper is entered in the Support type field, the Support dialog is updated to include additional fields. Vibration dampers are active only for static seismic and dynamic load cases (E1 - E3, R1-R10, S1-S3, F1-F3, H1-H3, M1-M3); they have zero stiffness for all other load cases. A damper may act along one of the global axes or in a specified direction. When all of the data is entered, accept the dialog by clicking on OK; the Damper support symbol will then be drawn at the specified point as shown. Typically for a static earthquake analysis E1 to E3 a damper element is used to lock up (i.e stiffness = rigid only acts in the E1 to E3 cases) the pipe but be 'free" in the thermal case. What you are describing I assume is the viscous component of the damper to overcome in order to move or lock up the damper. This is usually not a consideration for stress analysis of static seismic cases where it is assumed the snubber is designed to 'lock up' under earthquake (because of the nature of the suddenly applied load, the viscous force is so high such as to act as a rigid restraint) then move under a slowly applied load like thermal. There will be some resistance to movement in the thermal case due to the viscous dampening action but in AutoPIPE automatically assumes zero stiffness. The damper stiffness =RIGID is commonly used. In the dynamic analysis like time history again the damper is assumed to 'lock up' depending on the stiffness. Yes it may be appropriate to enter the Ns/m (ie Force/Velocity) for the snubber but AutoPIPE can only handle constant stiffness acting supports across the full travel of the pipe support. And again the dampening action is assumed almost instantaneous such the damper will act as a rigid restraint.
