Answer : We apologize for the inconvenience, however AutoPIPE cannot print its reports directly to MS word or MS Excel. Reports are currently written to the following files: *.OUT, *.HGR, *.RPT. These file can be opened by any text editor (i.e. NotePad, Ms WORD, ect..) . Also, AutoPIPE can export both the Input gids and Results grids to a database file (*.MDB), for manipulation into customized reports. This enhancement has been logged under CAE-CR-345: Add option to generate reports as EXCEL & WORD files. Items #5: Results are 0.00 or blank, Why? AutoPIPE Results Grids or Output Reports are found to be Zero (0.00) or Blank Item #6: What is +/- mean? What is the meaning of + and - (+/-) Node points in AutoPIPE results? Answer: Please see the following AutoPIPE help section: Help > Contents> Contents Tab> Reference Information> Results Interpretation> Pipe Forces and Moments: Global Option Item #7: Selected node points in output report Can we select a number of specific node points, pipe supports, etc. to report in the AutoPIPE result print out? Answer: Using any of the various method of selection, select the node points, supports, bends, etc. that are to be printed in the output report. After the selection process has been completed, perform a Model analysis as needed, and then selected Tools> Results> command. On the Batch report dialog screen, enable the first option " Limit results to highlighted points ", from the online help: Use this option to limit the reported results to only points which are currently selected and thus highlighted on the screen. Note: see the online help for complete details on this command. Continue checking any additional feature on the dialog as necessary, and press the OK button. The output will display only those selected points in the respective sub-reports selected. Item #8: How to customize output report: Can the output report or results grids be customized to export the information the way we want it? Answer: As mentioned in the online help, the Results> Output report command permits the user to specify the level of detail included on reports generated on the current model. The report can be limited to selected (highlighted) points or criteria specified in the Result> Filter options. In addition, the report will be generated in consideration of the current load combinations and the modal range. These printed reports have *.RPT / *.OUT file extension and can be opened by any text editing software for further manipulation. In addition, using Results> Grids command will provide a window consisting of tabs with tabulated data that are easy to highlight (i.e select the top, most left cell in the grid to highlight the entire grid) and copy into other applications like MS Excel or Ms Word for further manipulation. Furthermore, AutoPIPE's File > Export> Input Database or Results Database, will export information to a MS Access database (*.MDB) file. One limitation, not all of the sub-reports will be available in these exported files (i.e. General Stress reports, etc..). If a report is found to be missing a sub-section that you would like exported to an MDB file, please log a Service Request asking for a new enhancement to be logged on your behave. Once the *.MDB file has been created, it can be opened in MS Access or any other software that can read such a file format, where more powerful manipulations tools can be applied thus creating customized reports as needed. Item #9: %error allowed in the program? What is the accuracy rating for results in AutoPIPE compared to hand calculated values? Answer: Bentley AutoPIPE's accuracy has always been and will continue to be no more than 2.5% error. As mentioned in our ATS documentation: "The numerical results of the AutoPIPE Acceptance Test Set shall be within the acceptance criteria of nominally 2%, unless otherwise noted. Numerical results generated by other editions, or run under differing operating environments, are also expected to be within the same acceptance criteria (nominally 2%, unless otherwise noted).

Applies To Product(s): AutoPIPE Version(s): 2004, XM, V8i Environment: N/A Area: Subarea: Original Author: Bentley Technical Support Group Date Logged & Current Version Jan 2015 09.06.01.10 Problem: What is the difference between the "Operating Condition" and "Gasket seating condition" in AutoPIPE Flange analysis report? Answer: Using the ASME Section VIII Div. 1 analysis method in AutoPIPE. If you look at the code you will see there are these two conditions that need to be checked for, the operating condition and the gasket seating condition. The operating condition is used to verify the flange design will be sufficient enough to resist the maximum allowable working pressure. The gasket seating condition is used to verify the gasket will be “crushed” or seated in order to provide a sufficient joint. The bolt tensile stress is a comparison of the bolt loads used to satisfy the operating condition or the gasket seating condition against the bolt cross sectional area.

Wiki Page: E512-65: the model cannot be opened
Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Import Subarea: Original Author: Bentley Technical Support Group Problem The following is displayed while importing a file or opening the program: E512-65: the model cannot be opened as temporary directory cannot be set Solution: This error is typically caused by one the following reasons: Reason #1: The AutoPIPE program can only handle model path names with ASCII character set and does not support double byte unicode characters or Kanji characters in model path. In some earlier versions of AutoPIPE the program allowed the model to be opened if the model path has some non ASCII character, but many people reported the program of being unstable. The application would c rash on consistency check, analysis, or any report generation as soon as the commands were executed. Therefore, AutoPIPE V8i 09.02.xx.xx and higher now blocks opening such a model and display the error message shown above (i.e. E512-65...). Avoidance: only use ASCII characters in the file-path name. Reason #2: An issue with permissions on a file server can also cause problems. Avoidance: Confirm that the AutoPIPE user has read / write privileges to folders outside of C:\Program Files, ex. %temp% folder, C:\Bentley folder and sub-folders, etc.. In addition, users should have admin / power user permission rights to their own computer. Reason #3: The network server where the model is stored is operating a a slow speed. Symptoms: repeatedly opening the model the first 2x results in the error message but on the 3rd or more number of tries to open the model it opens without the error message. Avoidance: Move the model from the server location to the local hard drive, work on the model and when finished move the final model back to the network server. Also, ask your IT department to use network monitoring tools to better understand the problem and how best to fix it. Reason #4: This message may also appears when the path to model is too long. Avoidance: For AutoPIPE 9.4 and higher, make sure that the file path is shorter than 256 characters.

Wiki Page: Valves Piping Components - Modeling Approaches, Tips, Techniques used in AutoPIPE
Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: Modeling Subarea: Original Author: Bentley Technical Support Group Attention: Please see the following AutoPIPE help section: Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches> This help has been provided in order to give users ideas for modeling typical piping arrangements. The steps shown in each example should not be taken as the only method available to create models. In addition, the intent of the examples is to present ways to create adequate models of specific piping components for analytic purposes. Anchors Bends Cuts Flexible Joints Frames Hangers Nozzles Pipes Reducers Rotating Equipment Supports Tees Valves Vessels Comments, Questions, and Answers: Item #1: How to model a 3-way valve? Answer: Inputting three way valves in AutoPIPE is a bit convoluted at this time. AutoPIPE does not allow users to branch from a valve, see the following procedure: Start modeling from center connection point of the valve: Start from the connection point, insert a small pipe run (ex. 1 inch) Insert a valve Length = "measure from the center of the valve to the actual pipe connection" - "small pipe run in step A" Weight = 1/3 of the total valve weight from manufacture literature Insert pipe run for actual connected piping to the valve continue modeling piping system. Select the small pipe run from Step A, and Insert> Rigid Properties over Range> do not enable "Include weight" check-box, but check ON "Include Thermal Expansion" check-box Make the origin point of the small run the current node point, repeat steps A and D to create the other two legs. Note: before adding the 3rd leg, recommend to convert the intersecting junction point to a Tee using the "convert run to tee" icon / button. and then add 3rd leg. See image below for finish modeling approach. Insert 3-way valve on existing pipe run header At the end of a pipe run Insert a valve . Length = "measure from the center of the valve to the actual pipe connection" - "small pipe run in step B" Weight = 1/3 of the total valve weight from manufacture literature Insert a small pipe run (ex. 1 inch). Insert another small pipe run same as above (ex. 1 inch). Insert another valve with the same properties as above, Step A. Select both small pipe runs from Step B & C, and Insert> Rigid Properties over Range> do not enable "Include weight" check-box, but check ON "Include Thermal Expansion" check-box Make the node point shard by both small runs from Step B and C the current node point, convert the intersecting junction point to a Tee using the "convert run to tee" icon / button. On the branch of the Tee, add 3rd short pipe run and valve with same properties as above. Item #2: Valve Pressure rating drop-down list only shows NS (Non-Standard) Answer : Per the screen shot below, left Valve dialog is on 8" pipe, right Valve is on a 60 inch pipe. Note the image has only NS for Pipe Rating. the reason is because the pipe size is beyond that found in the current equipment library. Therefore only option available is to select a Pressure Rating = NS, and manually update the valve length. Item #3: How to model a complex valve such as a Bell & Gossett Triple Duty Valve in AutoPIPE? Answer : Modeling any type of valve in AutoPIPE is easy after the user understands some simple concepts. A valve component is modeled as a rigid pipe with additional properties and nice graphics. When modeling a valve of any complexity, model the functionality; i.e. rigid pipe properties, weight, type of end connections, offset weights (operator), and physical structure (additional rigid pipe or beams as needed). The following is an image of a Bell & Gossett Triple Duty Valve: Suggest modeling as a normal valve component with the correct length and weight. If concerned about the offset weight due to the body construction, insert valve's actuator to the correct location with an assumed weight, but be carefully not to double dip on weight. Another words, distribute the total valve weight between the following valve dialog fields: Valve Weight & Actuator Weight. Item #4: If I have a 90 deg angle valve or relief valve with the inlet pipe size smaller than the outlet pipe size, is it correct to model the pipe coming out of the valve as a different size than the pipe going into the valve? A warning message is given stating that the pipe diameter has changed without a reducer. Is it ok to ignore this warning in this case? Answer: Generally the vent pipe will always be bigger. There is currently 2 modeling approaches for an angle valve or relief valve: A. Model as a single valve on an incline: Please see the following AutoPIPE help section: Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches> Valves> Relief and Angle Valves Note: Although AutoPIPE cannot model a C.G. that is not outside the valve, AutoPIPE 9.1.1. can model a valve actuator at any orientation you wish and if that location corresponds to the location of the CG that would give a similar response. B. Modeled as two valves: model part of the valve in one direction with one pipe size and model the 2nd valve at 90 degrees with second pipe size. Note that the valves would be modeled as non-standard so that the weight is not automatically assigned. You can proportion the weight as you wish, Difference between the two model approaches: Not to be concerned, but analysis does show a very small difference in the results. This is due to the different type of construction, center of gravity; 1 valve at an angle vs 2 valves perpendicular. The following warning may appear in the model consistency check: W726-7: Pipe diameter change without a reducer at point XXX However, this is an acceptable warning to ignore because in order to model this component different pipe sizes were used without a reducer in both cases. The following enhancement has been logged, CAE-CR-11056, Add new valve type library for Press Safety / Relief Valve (PSV or PRV). Item #5: How do I analyze for a air high pressure relief valve? Answer: See AutoPIPE/Help/Workbook/Example Systems/ Water Hammer and simply change the fluid to steam or NS (non standard). Item #6: When inserting a valve with flanged end connections on both side, the wrong weight is automatically applied to the flanges. example: add a GateF Class 300 valve and tick the insert flanges option the flanges by default are the same weight as the valve. Answer: This is a known issue and has been logged under CAE-TR-10614 Using insert flange on both ends copies the weight of valve to flange and was fixed in AutoPIPE V8i 09.06.00.07 and higher. Item #7: How do I model a Fire hose valve? Answer: There are a few different varieties of Fire Hose Valves: angle type, in-line type, Wye type, etc.. When modeling a valve in AutoPIPE, the most important information is valve configuration, and end type connections. In the background, a valve is just a graphical image of rigid pipe with known weight and the correct SIF values for end connections. Therefore, model the geometric shape of the custom valve with piping components, add Rigid Pipe Properties as needed over this piping, insert added weight as needed, and insert the correct SIF values for all en connections. Note: 1. Caution, try not to double count weight from all components used in your custom valve (i.e. rigid properties, valve components, reducer components, added weight, etc.). 2. Model the Wye using the same general modeling approach as see in 3-Valve procedure above. 3. AutoPIPE's SIF calculations are all based on Piping codes. Locate a source to help calculate the correct SIF values for Fire hose connections to be used in AutoPIPE. Suggest contacting the valve manufacture for assistance. Item #8: Can you suggest a modeling approach for the following valve + actuator where the supplier only provides info on the combined unit weight and CG but no individual component (valve weight, actuator weight, etc..) details? Answer: Insert the actuator at the CG location and enter the combined valve and actuator weight on the actuator Enter valve weight = 0 Item #9: Logged Nov 2014, AutoPIPE V8i 09.06.01.10 How to model a Butterfly valve? Answer: At this time there is no valve library exclusively for butterfly valves. Therefore, mode the valve using Valve type = NS (Non-Standard) and then enter the correct values for the rest of the dialog screen as needed. Select OK button to close the Valve dialog. Item #10: Logged Jan 2015, AutoPIPE V8i 09.06.01.10 How to model a Large double offset valve Answer: Assuming the valve is installed vertically up as shown above. 1. Model piping to the inlet BW location (A00). From this point model the same size piping to the center-line of the valve (A01). 2. Model from center-line of inlet valve vertically down to center-line of exit piping (A02). 3. Change to Exit Pipe Properties size. Model horizontally from center-line of exit piping to exit flange location (A03) and insert a flange component. Flange weight - 0.00 lbs. 4. Highlight all the piping that represent the equipment (A00 - A03) and insert "Rigid options over range" with "include weight" checked OFF and "Include thermal expansion" checked ON. 5. Next need to account for the weight of the equipment. You have options here. Choose one of the following: a. select from A00 to A03, insert distributed load, combine with load case = GR, determine the weight of the equipment and spread it out evenly across the selected pipe. OR b. Insert all weight at one location, Insert> Extra Data> Weight = total weight of equipment. 6. Done.

Bentley's Technical Support Group requests that you please submit any comments you have on this Wiki article to the "Comments" area below. THANK YOU! If I add a valve e/g/GateF Class 300 and tick the insert flanges option the flanges by default are the same weight as the flange, hence not the correct flange. I stopped using this option because of this and instead I would just add the valve, then I would highlight thevalve and click insert flange, click insert mating flange and everything looks fins but when I checked things later I found that two flanges has been inserted at each end (4 flanges in total for one valve). Have newer versions fixed this?

Wiki Page: FAQ about AutoPIPE's ATS
Applies To Product(s): AutoPIPE, Version(s): 2004, XM, & V8i Environment: N/A Area: ATS Subarea: Original Author: Bentley Technical Support Group Item #1: I am trying to locate the reference information for the equations used to validate the AutoPIPE software as stated in the ATS documentation. "THEORY: Refer to the AutoPIPE Reference Information in the AutoPIPE Online Help, for details on the equations used by AutoPIPE for calculation of stresses." Furthermore can you send me the copies of the mathcads sheets showing the hand calculations for a specific model? Answer: Typically, the reference equations can be found at the following AutoPIPE help section: Help > Contents> Contents Tab> Reference Information> Code Compliance Calculations> select the correct piping code. The overall objective of this ATS is to provide a means of validation for the AutoPIPE computer program to analyze and produce accurate results for a variety of piping models as installed in a specific operating environment. The accuracy of AutoPIPE is verified by Bentley during execution of Alpha Tests, which are performed prior to any Commercial or Quality Assured release. Alpha Tests consist of a matrix of test systems designed to capture key feature attributes related to numeric and functional processing. Each set of test outputs is compared to a prepared set of expected results (i.e. MathCADs, hand calculations, some other well established computer program etc.), and evaluated for acceptance. Only those people who are part of the QA&R program have a right to access Bentley's facility in Walnut Creek, CA for the purpose of QA audits or inspection to verify the implementation of our quality assurance program. Only during the audit can QA&R user have access to all the references mentioned above. Item #2 I was running the Acceptance Test Set of AutoPIPE Nuclear 9.4.1.5 on our Technical Server and the Error Log showed differences we did not find when installing on our Personal Computers. Answer : The fact that operation ran flawlessly on your system tells us that the AutoPIPE and ATS installation are working correctly. Also, tells us that something is wrong with one of the following: your log in access to the Technical server, missing files, server communication, etc.. Your IT department should be able to assist you compare folders, access rights, and Read/Write folder settings. When logging a service request please be sure to supply all the information about your computer and the server computer. Item #3 AutoPIPE: model missing from ATS During review of the AutoPIPE ATS document (ap_ats.pdf), some models (ex.QA 262-6.dat) are missing and are not listed in the Test Set Execution Status Matrix TR Number: None Product: AutoPIPE Version: all Area: General Problem ID#: 71089 Answer: In the AutoPIPE ATS document (ap_ats.pdf), just before "Description of Acceptance Test Systems", is a note that reads" " * These test sets are not part of the published Acceptance Test Set Manual." The ap_ats.pdf lists all the models that are part of our QA&R testing. However, not all these models are available in the ATS. So any models listed in the "Test Feature Cross Reference" part of the document with an "*" next to the model name is not available in the Automatic test set. Accounts that are signed up as Q&AR have an extra privilege to visit the CAE group facility in Walnut Creek, CA. to review all of AutoPIPE's models, documents, and calculations. This is by appointment only. Please see the following WIKI site about QA&R subscription details . Item #4: After running the ATS the log shows some discrepancies for certain test files. What is considered acceptable messages in the error log file? Answer: After successful installation of the AutoPIPE V8i SELECTseries 4 ATS, a desktop shortcut to the ATS program group containing five new icons would be created: 1. ATS Documentation - detailed document about ATS program. 2. ATS Readme. - general technical data about the application. 3. Read1st.ATS. 4. Review AutoPIPE ATS Results in Error.log. It is vitally important before running an ATS that all user read these documents. Note: under the "ATS Documentation", "RECOMMENDED VERIFICATION PROCEDURES", step #6: "Note that there will always be a few differences captured in the log file. These differences are due to the date/time stamping of the analysis files which are captured in the Analysis Summary sub-report produced for several (but not all) of the test systems. Also, there may be minor numeric differences, refer to the Acceptance Criteria section for further details." In addition, see " Appendix B: AUTOMATED SYSTEM PROCESSING MATRIX " of the same document: The following table lists the test systems executed by the Automated System Processing Method for each AutoPIPE edition ( Standard, Advanced, Advanced + KHK, Nuclear, and Nuclear + KHK). Therefore depending on your application license and computer one or more of the following may occur: Time / date difference Results may be off by up to but not exceeding 2% of documented values. Not all model will have results based on system process matrix Item #5: How soon will the ATS be ready for AutoPIPE Nuclear Version xxx? Answer: After a new version of AutoPIPE has been released, the CAE development team is tasked with creating the AutoPIPE ATS program and documentation. It takes a considerable amount of time and effort to produce an Automated Test Set; new model creation, new supporting mathcads, updated documentation, updated software, Certifications, etc.. Therefore not every version of the software will have an ATS . The CAE development team will post the ATS and documentation when it is completed and send out notifications to all the QA&R users. Otherwise, periodically check AutoPIPE Help RSS news feed or Bentley software download site to see if a new ATS has been posted. Furthermore , the ATS software version must match the AutoPIPE software version mentioned in the documentation. You CANNOT mix the versions of these applications as it will void the test. As an example: cannot use AutoPIPE V8i 09.06.00.19 with AutoPIPE ATS 09.05.01.02. QA&R users are urged to contact the QA&R Software Quality Manager for details on estimated time of arrival for their software shipments. They are tasked with performing all the testing and distribution of all software to QA&R user. Again, other user are urged to periodically check AutoPIPE Help RSS news feed or Bentley software download site to see if a new ATS has been posted Item #6: What is the list of currently available ATS versions for AutoPIPE: Answer: As of Jan 2015, current list of ATS available for AutoPIPE AutoPIPE V8i 09.06.01.11 AutoPIPE V8i 09.05.01.02, 09.05.01.05 AutoPIPE V8i 09.04.01.05 AutoPIPE V8i 09.03.02.05 AutoPIPE V8i 09.02.03.02 AutoPIPE V8i 09.01.01.02 AutoPIPE XM 09.00.00.08 AutoPIPE XM 08.09.00.14 AutoPIPE 2004 08.06.00.12 As one can see, not every version of AutoPIPE has an ATS created. Check the software download 1-3 months after a release of a new version of AutoPIPE to see if an ATS has been posted. Also check AutoPIPE's online Help> AutoPIPE News RSS news feed for notification. One perk about the QA&R program, all QA&R user are automatically notified.

Wiki Page: Import / Export CEASAR (cii) file - AutoPIPE
Applies To Product(s): AutoPIPE Version(s): 2004, XM, V8i Environment: Windows 2000, Windows 7 32 bit, Windows 7 64 bit, Windows Vista 32 bit, Windows Vista 64 bit, Windows XP 32 bit, Windows XP 64 bit Area: Import / Export Subarea: Original Author: Bentley Technical Support Group Date Logged & Current Version Jan 2015 09.06.01.10 Problem Description Can AutoPIPE import / export to CAESAR? Troubleshooting question / answers TR Number: Product: AutoPIPE Version: 09.04.00.19 Area: General, import Problem ID#: 75697 Solution: Yes, AutoPIPE can import / export files with CAESAR. The File> Import> Caesar II Neutral (*.cii) command is a means for importing CII neutral files created from Caesar II models. These drawing must first be prepared in their native program before being imported into AutoPIPE. The process involves two main steps: Export the model as a CII neutral file in Caesar II. Importing a Caesar II Generated Neutral File Note: AutoPIPE V8i 09.06.00.19 and higher is capable of imported Caesar II v6.1 files, and earlier. To export a model from AutoPIPE to Caesar, convert the AutoPIPE model *.DAT into a *.CII format, Select File> Export> Caesar II Neutral (*.cii) AutoPIPE and CAESAR share a lot of commonality in function but do not share the same concepts of programming. Caesar uses various types of elements to create a model, whereas AutoPIPE model is built by defining a series of piping points where each successive point is reliant on the DELTA distance offset from the previous point back to the ORIGIN point. However, both approaches result in the same model and hence components can be mapped from one to another. Caesar neutral files do not contain all the information defined by the user. The missing information cannot be translated into AutoPIPE. In general, all data on the Caesar main spreadsheet and all auxiliary spreadsheets is translated into AutoPIPE. This includes all piping geometry (except fiberglass), supports, pressure and temperature loading, forces and moments, displacements etc. Occasional loads (wind, earthquake and dynamic load) cannot be translated and should be redefined in AutoPIPE. See AutoPIPE online help for all the details of importing / exporting files between these applications. Please see the following AutoPIPE help section: Help > Contents> Search Tab> enter "CAESAR" (include the quotes), press List Topics button, double click on the selected topic from the list provided to see more information. ATTENTION: Be sure to note the limitations on the "Caesar CII Mapping" help page Node Number Mapping Component Mapping Support Mapping Load Case Mapping Limitations Select the appropriate hyperliink below for addtion information: Import Issues and FAQ's Export Issues and FAQ's IF you are still having issues with importing / exporting CAESAR cii file that is beyond that covered in the AutoPIPE’s online Help, please submit a Bentley service request with the AutoPIPE model, CAESAR file, screen shots of exactly the problem with related node numbers from both models for each occurrence to be reviewed.

Anyone on a project team for the first time in Bentley Navigator can view a detailed piping or structural analysis model complete with all the modeling and result data alongside the "real-time" 3D CAD model in order to make early design decisions and avoid costly mistakes. Using ProjectWise collaboration servers, distributed engineering is now possible with remote teams around the world. State-of-the art modeling and analysis Do you have difficulty correlating your model data with your piping system? Enjoy the power of bi-directionally synchronized Excel style spreadsheets with a graphical plot. Changes in either plot or grid are updated in real time. Like Excel, you can hide columns, easily make global changes across multiple cells or columns; you can uniquely sort any column to quickly find differences in the data or create customized printouts of any grid to PDF format. Bentley AutoPIPE also offers graphical copy and paste functionality for quick modeling and the ability to deal with changes in a timely manner. Bentley AutoPIPE like all other stress programs uses 1-D finite elements which use simple Beam element center-line based theory, also known as the stiffness or displacement method, to mathematically model the piping system in three dimensional space. The system is formulated into a set of linear equations, describing the system characteristics at each degree of freedom (DOF). However, AutoPIPE differs from other applications because each point (e.g., piping, soil, beam, etc.) in an AutoPIPE modeled system has six (6) degrees of freedom. The exact formulation of these equations and their solution depends on the type of loading being investigated. Bentley AutoPIPE has an advanced non-linear engine developed by Prof. Emeritus (UC Berkeley) to perform load sequencing not found in other programs. It also includes built-in wave loading , industry recognized buried pipeline analysis , dynamic loadings , and orthotropic FRP/GRP piping analysis; thermal bowing of hot partially filled pipes , pipe/structure interaction , fluid transient with closure time, and relief valve utilities , non-linear support gaps and friction and jacketed piping . Intuitive GUI modeling AutoPIPE offers an always present graphical user interface that enables the user to dynamically input graphically for faster modeling and modifications. Our one screen CAD -like graphical environment is the most intuitive in the industry, with 3D OpenGL rendering and smart component graphics for realistic animation and visualization. Intelligent object technology No other pipe stress program can offer the intelligent object technology for faster modeling to build complex models in seconds or share pipe support layouts with other engineers on the project . Object technology allows the user to graphically select components or pipeline segments to apply loadings, soil, or different types of data in one easy operation without entering the data for each element one by one. Comprehensive design codes Now used in 55 countries for the last 20 years, Bentley AutoPIPE has maintained the latest codes and features of 29 international piping codes and standards for ASME, British, European, German, Japanese, Chinese, API, NEMA, ANSI, ASCE, AISC, UBC, and WRC. Previous codes are supported for plant retrofits and more than 20 pipe support spring manufacturers from the United States to United Kingdom, Spain, India, Japan and China. Developed as a scalable solution to meet the needs of companies working in industries like nuclear and fossil power, process and chemical plants, offshore FPSO platform and riser design, fire protection systems, oil refineries, cross-country gas and oil pipelines, FRP piping, and building services piping. Highest quality standards Does your company receive patches every few months to fix bugs and reliability issues with the piping analysis software you are currently running? Does your current software supplier provide a full publishable list of defects in the program complete with solutions or workarounds on their website or discussion forum? Do you feel you are the software tester having to report problems with the program? AutoPIPE is the only pipe stress analysis software on the market that adheres to the strictest external quality standards , including 10CFR21 , NQA-1 and the nuclear certification by NUPIC and NRC customers. This requirement will be mandatory in the near future. ANSYS and AutoPIPE are the two leading approved analysis software programs by NUPIC for Nuclear Plant Utilities in the United States. And now with the integration of the leading nuclear ADLPipe solution, we will provide the most comprehensive nuclear piping solution on the market.

Customize metric or english drawing sizes, viewing angles, north arrow, margins, and overflow. Choose to annotate the plot with engineers comments for the CAD designer or contractor and add support tags or reference equipment like pumps or steelwork. Place customized data tables for piping, flange, and valve data or summary result tables for maximum support loads, spring hanger report for procurement and stress summary. Comparing AutoPIPE to Your Current Pipe Stress Program: Overview This article will enable you to quickly verify for yourself whether or not your current piping stress analysis program may have limitations which can prevent proper calculation of basic ASME B31.1 orB31.3 piping code stresses when more than one thermal operating condition is analyzed. In a typical plant, valves are opening and closing, pumps and other equipment are running hot and cold, shutdowns may occur in the middle of a cold winter, or cryogenic applications may be required, to name a few of the possible scenarios which may occur. Given these possibilities, the piping engineer often does not know which scenario will result in the worst-case stress condition. As a result, it is often necessary to analyze more than one operating condition in order to accurately determine worst-case stresses and loads. The ASME B31.1 and B31.3 piping codes require users to calculate stress ranges not only from ambient temperature to the various thermal operating conditions, but also the stress ranges between these operating conditions. The piping codes further state that users must consider externally imposed displacements together with thermal displacements in order to properly calculate the total displacement stress range. When thermal conditions change, externally imposed displacements will change as well. Vessels, pumps, turbines and other equipment connected to the piping system will grow or shrink, depending on the thermal conditions. Please consider the following example of an auxiliary steam system analyzed with the AutoPIPE piping stress analysis software, (see Figure 1 below). Figure 1 The piping system has two operating conditions to be analyzed. The first one is all hot (T1), and the second condition (T2) is when the valve at node. B2 is closed, thereby resulting in a cool down of the branch line from 600°F to 120°F starting at the valve, and a change in the externally imposed displacement at anchor node B6 from 1" growth in the Y direction in the first thermal condition case (T1) to only 1/10" growth in the Y direction in the cool down condition case (T2). Please remember that the ASME B31.1 and B31.3 piping codes require a stress range to be calculated not only from ambient to thermal condition 1 (cold to T1) and ambient to thermal condition 2 (cold to T2), the codes also require that a stress range be calculated between the two operating conditions (T1 to T2). As you can see from the analysis results (see Figure 2), the worst case B31.3 piping code stress calculated by AutoPIPE was in stress range case T1 to T2 at branch point A7 with a 43,837 psi stress that failed piping code compliance. You can quickly input and analyze this system for yourself with another piping stress program. Results from piping stress analysis programs other than AutoPIPE will likely show that the system passed code compliance with only about 26,700 psi stress (compared to 43,837 psi!) at branch point A7, when in fact, the system was considerably over-stressed at that branch. Run the same analysis using ASME B31.1 and you will see an even larger disparity between AutoPIPE and other piping stress programs. Why would other piping stress programs differ from AutoPIPE by such a wide margin in the calculation of B31.1 and B31.3 piping code stresses? Answer: Some programs are limited to only one (1) set of anchor displacements and one (1) set of support displacements, no matter how many thermal operating conditions must be analyzed. Since equipment grows or shrinks depending on thermal conditions, such a limitation on anchor/support displacements can have a profound impact on the calculation of piping code stresses when more than one thermal operating condition is analyzed. Other piping stress programs are incapable of calculating a stress range between multiple thermal operating conditions (some can't calculate the Tl to T2 code compliance case). The Wrong Approach "No problem", we often hear from users, "I'll just run two jobs, one job with the anchor displacement from thermal condition 1 and another separate job using the anchor displacement and thermal conditions of case 2". This idea sounds acceptable, although time consuming, until you consider the fact that you cannot calculate a stress range between 2 different thermal operating conditions (you can't run the Tl to T2 case) when these two conditions are run as separate jobs. Try the example for yourself. The results from most piping stress programs other than AutoPIPE will show that the system has passed code compliance when, in fact, the system failed. Since the worst case stress in piping code compliance is quite often the stress range between different thermal operating conditions (T1 to T2, T1 to T3, T2 to T3, etc.), the ability to calculate a stress range between multiple operating conditions, while considering different external displacements in each thermal condition, can make the difference between passing or failing ' code compliance as the steam system example demonstrates. Cryogenic applications, pumps in series with different pumps operational and idle, winter shutdowns, and safety relief systems, arc situations, which typically require the analysis of multiple thermal operating, conditions. As a footnote, most piping stress software programs other than AutoPIPE are limited to only one earthquake load direction and/or only one wind load direction for analysis (typically, wind and earthquake loads need to be analyzed in at least 2 directions). This limitation makes it very time consuming and error prone to manually sort through output from separate job runs to determine worst case support loads, worst case equipment loads, and worst case stresses from multiple wind directions and/or multiple earthquake loads. Figure 2 AutoPIPE Capabilities in Comparison In one analysis, AutoPIPE will automatically perform piping code compliance, calculating stress ranges with up to three (100) sets of temperatures and pressures using different anchor and support displacements for each different thermal condition. In the same analysis, AutoPIPE will analyze support and equipment loads with consideration of multiple wind directions, multiple earthquake loads, and up to 13 dynamic occasional loads. AutoPIPE output displays the greater of earthquake stress and wind stress at each point, while summarizing all loads on each restraint and equipment nozzle with rotating equipment compliance in one analysis. If your piping stress software does not perform these functions automatically, then you can determine for yourself how many problematic piping code compliance stress calculations may have been made, and how many man-hours have been spent running separate jobs. Bentley strongly emphasizes the CAD interfaces offered by AutoPIPE for AutoPLANT, PRO-PIPE. Intergraph PDS and other plant design systems. Although AutoPIPE's commitment to CAD interfaces is a strong benefit for users, it is often overlooked that AutoPIPE provides important stand-alone capabilities not available with other piping stress programs, enabling users to more quickly and reliably analyze their piping systems. Attention : For current specs on AutoPIPE capabilities, please see the following AutoPIPE help section: Help > Contents> Contents Tab> Getting Started> AutoPIPE V8i Standard vs Advanced vs Nuclear. Example: AutoPIPE V8i 09.06.01.10: Note: Maximum number of load cases that can be analyzed in a single analysis set during a static analysis run in v9.1 and later. However an unlimited number of analysis sets can be run in a single static analysis in v9.1 and later. = Gravity (1) + Thermal (20) + Pressure (20) + Static Earthquake (20) + Wind (10) + Snow (1) + User (20) = 83 cases for Advanced & Nuclear (28 for Standard) Up to 100 different thermal loadings can be defined and analyzed in a single static analysis. Only 20 thermal load cases per analysis set e.g. if want to run 50 thermal cases then define across 3 analysis sets. Since each analysis set can have analyze up to 82 static cases, so literally 100’s of loads can be analyzed in different scenarios with different options, linear, non-linear, hot or cold modulus etc in the same static analysis run. Evaluate AutoPIPE Before You Buy: As you have come to understand after reading the above information, AutoPIPE is a very powerful tool.
