Item #1, Comment: Be sure to review the following AutoPIPE online help information: Help > Contents> Contents Tab> Reference Information> Code Compliance Calculations> This area describes variables, equations, and methodology used by AutoPIPE to produce output reports per the code associated with the piping system database. AutoPIPE is capable of generating actual and allowable stresses for each of the applicable stress categories (depending on the current, analyzed load cases) for all codes listed below. Please Note: The Standard edition only has access to 4 ASME codes and European code EN13480 as shown in the Getting Started topic "AutoPIPE Standard vs Advanced vs Nuclear". Select the Piping code hyperlink below for general questions about the code's calculations. Note: 1. additional hyper links are added as new information is presented. 2. Allowable values are calculated based on code requirements. See the online help location mentioned above for details. Example: Allowable calculation for ASME B31.1 (2012), "Stresses Due to Sustained Loads" category. Please see the following AutoPIPE help section: Help > Contents> Contents Tab> Reference Information> Code Compliance Calculations> ASME B31.1 (2012)> Stresses Due to Sustained Loads> Read the information, the allowable calculation is mentioned in the write-up. "AutoPIPE reports sL, and the allowable stress (SH) ." The allowable calculation for this category is ( SH ). In addition, other settings under Tools> Model Options> Results may affect the allowable calculations (i.e. Sustain Margin (Y/N/E), etc..) ASME B31.1 Power Piping ASME B31.3 Process Piping ASME B31.4 Liquid Transportation Systems for Hydro-carbons, Liquid Petroleum Gas, Anhydrous Ammonia, & Alcohols ASME B31.8 Gas Transmission & Distribution Piping Systems ASME B31.4 Chapter IX Offshore Liquid Piping Systems ASME B31.8 Chapter VIII Offshore Gas Transmission ASME BPV-III-1-NB Boiler & Pressure Vessel Code, Rules for Construction of Nuclear Power Plant Components Division 1, Subsection NB, Class 1 Components ASME BPV-III-1-NC Boiler & Pressure Vessel Code, Rules for Construction of Nuclear Power Plant Components Division 1, Subsection NC, Class 2 Components ASME BPV-III-1-ND Boiler & Pressure Vessel Code, Rules for Construction of Nuclear Power Plant Components Division 1, Subsection ND, Class 3 Components HDPE - CC N-755-1 High-Density Polyethylene JSME S NC1-PPC Rules on Design and Construction for Nuclear Power Plants, Class 2 Piping BS806 Design and Construction of Ferrous Piping Installations For and In Connection with Land Boilers SPC Swedish Piping Code, Code for Piping in Stationary Plants (Stress Analysis - Method 2) TBK5-6 Norwegian Pressure Vessel Committee, General Rules for Piping Systems STOOMWEZEN (D1101) Dutch Piping Rule D1101 of the Rules for Pressure Vessels CAN/CSA-Z662 Canadian Standards Association, Oil and Gas Pipeline Systems DNV Norwegian Piping Code, Rules for Submarine Pipeline Systems MITI501 Technical Standards for Construction of Nuclear Power Plant Components - MITI Notification No. 501 KHK Level 1 KHK E 012 Japanese Piping Code for Seismic Loads, Level 1 KHKLevel 2 KHK E 012 Japanese Piping Code for Seismic Loads, Level 2 EN13480 EN 13480 European Standard for Metallic Industrial Piping RCC-M French Piping Code SNCT French Piping Code SNiP Russian Trunk Pipelines Code BS7159 Design and Construction of Glass Reinforced Plastics (GRP) Piping Systems for Individual Plants or Sites ISO 14692 Petroleum and Natural Gas Industries, Glass-Reinforced Plastics (GRP) Piping General General Piping Code Item #2, Question: Why does AutoPIPE ignore axial force in most of the code equations? Answer: Confirm the model is considering axial force, as this option by default is turned OFF. See Tool> Model Options> Results> "Include axial force" option Excerpt from online help: The piping codes ignore the effect of axial force for calculating stresses in the sustained and occasional categories (only bending moments are considered, see Code Compliance Calculations). This option has been provided to allow the inclusion of axial force effects. By default this option is unchecked.... See online help for more information on this option. Item #3, Question Our Project Design Specification calls for ASME II 2010 for Material and ASME III 2007 with 2008 addenda for Rules for construction of nuclear facility components. However, there is no exact selection of ASME III Code year within AutoPIPE. Please advise the appropriated setup for ASME III Nx Stress analyses with above described Code year. Answer: AutoPIPE V8i 09.06.xx.xx and lower has the following nuclear codes for selection: ASME BPV-III-1-NB (1972 - 2007) Boiler & Pressure Vessel Code, Rules for Construction of Nuclear Power Plant Components Division 1, Subsection NB, Class 1 Components (1972 + 1972 W addenda, 1974 + 1975 W addenda, 1977, 1980 + 1982 W addenda, 1983 + 1983 W addenda, 1986 + 1988 addenda, 1989, 1989 + 1989 addenda, 1992 + 1994 addenda, 1995 + 1997 addenda, 1998, 2001, 2004, and 2007) ASME BPV-III-1-NC (1972 - 2007) Boiler & Pressure Vessel Code, Rules for Construction of Nuclear Power Plant Components Division 1, Subsection NC, Class 2 Components (1972 + 1972 W addenda, 1974 + 1975 W addenda, 1977, 1980 + 1980 S addenda, 1983 + 1983 W addenda, 1986 + 1988 addenda, 1989, 1989 + 1989 addenda, 1992 + 1994 addenda, 1995 + 1997 addenda, 1998, 2001, 2001 + 2003 addenda, 2004 and 2007) ASME BPV-III-1-ND (1972 - 2007) Boiler & Pressure Vessel Code, Rules for Construction of Nuclear Power Plant Components Division 1, Subsection ND, Class 3 Components (1972 + 1972 W addenda, 1974 + 1975 W addenda, 1977, 1980 + 1980 S addenda, 1983 + 1983 W addenda, 1986 + 1988 addenda, 1989, 1989 + 1989 addenda, 1992 + 1994 addenda, 1995 + 1997 addenda, 1998, 2001, 2001 + 2003 addenda, 2004 and 2007) As you can see there is currently no 2007 + 2008 addenda edition. This enhancement has already been logged under CAE-CR-6978: "Update ASME NB NC and ND code to 2008 addenda" and will be included in a future build of the application. Please review the code as there is not much difference between 2007 release. With regards to which code to select from the Tools> Model options> General> Piping code> drop down listing, due to liability law suits Bentley TSG is not at liberty to dictate what piping code / year should be used in your model. That is for you to determine. Recommend reviewing the possibility of using ASME NB, NC, or ND piping code. Most of the material data in the libraries associated with the Nuclear Piping codes has come from ASME BPV-III. Please see the online help for details of what code year. Help > Contents> Search Tab> enter "BPV-III" (include the quotes), press List Topics button, double click on the selected topic from the list provided to see more information. Item #4, Question: What piping codes should be used for offshore design? Answer: Consider using one of the following piping codes: ASME B31.4 - Chapter IX, Offshore Liquid Pipeline Systems ASME B31.8 - Chapter VIII, Offshore Gas Transmission Z662-07 - Oil and Gas Pipeline Systems DNV-OS-F101 - Submarine Pipeline Systems Item #5, Question: 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% 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). Therefore, edition specific output comparison files will not be provided." Item #6: Question: What Russian Codes (and ASME equivalents) can AutoPIPE be used for? Answer: Bentley AutoPIPE includes the latest Russian SNIP 2.05.06-85 for design of above and underground Oil and Gas pipelines has successfully been certified as meeting the Russian GOST standard.

Wiki Page: 03. Using AutoPIPE V8i 09.06.00.15, with ASME B31.4, what is the difference between the 2 settings for restrained soil analysis?
Applies To Product(s): AutoPIPE Version(s): ALL Environment: N/A Area: Calculations Original Author: Bentley Technical Support Group Date Logged & Current Version Sept. 2015 09.06.02.06 Problem: Question: Using AutoPIPE V8i 09.06.00.15, with ASME B31.4, on the input grid Piping Restraint tab shows, stress equation column: On Tools> Model Options> Results> : Solution: When ASME B31.4 2009 or higher is selected, an option is added in the Xtra Data menu named "Piping Restraint Options". This option is only used to control which combinations are displayed on the output report, result grid, and interactive scan. AutoPIPE classifies certain equations as Restrained, and others and unrestrained and performs the calculations accordingly. P = Internal pressure (AutoPIPE considers the maximum pressure from all available operating cases) D = Outside Pipe diameter t = Pipe wall thickness (depends on Result Model Option "Use nom. thk. for Hoop") ZL = Longitudinal weld factor defined for each pipe ID (default = 1.0) Y = Y factor defined under Model Result Options (may be used to control Thick/Thin wall pipe formula application for Hoop stress, default = 0.0) E = Weld efficiency factor (defined under Result Model Option "Weld Efficiency fac Ej" - global option, default = 1.0) Sy = Specified minimum yield strength of pipe i = In-plane SIF M = Bending moment due to gravity load Fa = Axial force due to gravity and pressure load cases (axial force is always included and is not dependant on the Result Model Option "Include axial force") A = Cross sectional area of steel (wall thickness used in cross sectional area calculation depends on the Result Model Option "Use nominal thickness") Z = Section modulus (wall thickness used in section modulus calculations depend on the Result Model Option "Use nominal thickness") Note: 1. See Code Table 403.3.1-1 and code section 403.3.2 for most of the Allowable values in the table above. 2. Use the user allowable fields under code combinations to input a user allowable as needed. When the Result Model Option "Use rest. long. code eq." option is checked, AutoPIPE then uses the exact code equation to calculate the Longitudinal stress regardless of the support configuration and actual forces. By default, all piping points are set to Unrestrained Note: Piping Restraint tab, stress equation column, this setting will only determines what stress equation will be used during the stress analysis. The user will still need to model the appropriate soil properties for all underground piping. See Also ASME B31.4 Piping Code Calculation Issues Bentley AutoPIPE d10582

Wiki Page: 04. Support report indicates a load on a support who's open gaps never closed during an AutoPIPE Analysis, so why is there a load on the support in open gap direction?
Applies To Product(s): AutoPIPE Version(s): 2004, XM, V8i Environment: N/A Area: Report Original Author: Bentley Technical Support Group Date Logged & Current Version June 2015 09.06.02.06 Problem: When reviewing the load on a gaped support, there is a load in the same direction as a large gap. The pipe never closes the gap, so why is there a load on the support in that direction? Solution: If you are running a non-linear analysis, 9 times out of 10 the answer is due directly with Load sequencing. Please see the following WIKI page here Otherwise remember that all dynamic analysis depend on Modal Analysis results and are subject to the rules of performing a Modal Analysis. Note: if using a guide support where 2 opposite directions have large gap settings. Highly suggest to model using an Incline support instead of a Guide support.

Wiki Page: 06. Non-linear Load Sequencing Explained
Whenever a static analysis load set includes Gaps/Friction/Soil it is calculated using a non-linear analysis. As a non-linear analysis, individual load cases (i.e. Gr, T1, P1, E1, W1, etc..) are applied one at a time in a sequence. This specific sequence does affect the calculated combination results. For example, see Analysis Summary output report: Here one case clearly see that the Load Cases analyzed are Gr, T1, E1, and W1. Also that the load sequence was: 1st, analyze load case GR. 2nd, from the displaced pipe location due to Gravity, add load case T1. 3rd, again, from the displaced pipe location due to Gravity, add load case E1. Lastly, again, from the displaced pipe location due to Gravity, add load case W1. Conversely, pipe displacement and support load results can be significantly different if the Wind loads were applied to a piping system that had already been displaced by operating conditions, example OP1: Here one case clearly see that the Load Cases analyzed are Gr, T1, E1, and W1. Also that the load sequence was different than above: 1st, analyze load case GR. 2nd, from the displaced pipe location due to Gravity, add load case T1. 3rd, again, from the displaced pipe location due to Gravity + T1, add load case E1. Lastly, again, from the displaced pipe location due to Gravity + T1, add load case W1. How to perform a Non-Linear Analysis? On the Static Analysis Sets dialog screen, check boxes in the "Non-Linear" column . OR Select an Analysis set and press the modify button to open the dialog below. Enable setting for "Gaps/Friction/Soil" and press OK button. How to define Non-linear options? As mentioned above, enable to the setting "Gaps/Friction/Soil" and press OK button. Now the Non-Linear Analysis options dialog will appear. S ee online help for details on this dialog screen. Note: Why does NonLinear Analysis provide the following options on the dialog above: “Ignore friction GR” "Ignore friction E” How to control load Sequence? There are 2 settings to control load sequence both options are accessed by Non-Linear Analysis options dialog mentioned above. 1.Initial case for Occ. loads 2. Use default sequence For more complicated load sequence, uncheck the "Use Default Sequence" box to modify the Load sequence and press OK button as shown below: Now manually adjust the load sequence as needed. There are some limitations to load sequence: 1. Initial state for occasional load cannot be another occasional load case. 2. Initial state for occasional load cannot be a User load case. 3. Initial state for User load cannot be another User load case. etc... Attention: 1.

Discussion of AutoPIPE Advanced Non-Linear Analysis Engine Note: V-stop lift-off message is displayed by AutoPIPE when a pipe is resting on a V-stop in sustained/dead load condition i.e. gravity (which means that the support force displayed in the grid in the Global vertical axis would be negative, meaning that force is acting downward on the v-stop), but the pipe lifts-off from the support (Zero force acting on the support in global vertical axis, displacement of the point would be positive in global vertical axis) under operating loads i.e. Pressure or temperature. The maximum possible frictional force that can be developed for a support depends on the bearing (vertical) force applied to that support point, forces applied in the orthogonal direction to bearing and the friction coefficient.

Non-Linear Analysis - Pipe / Support Friction Force Item #2: When looking at the output report In the output report only look at the operating conditions (i.e. GT1E1, GT1W1, etc..) and not the individual load cases (i.e. Gr, T1, E1). The individual load case(s): A. may have displacements that are larger than a gap on a support allows or B. support may have a load in a direction of a gap. However, when the individual load cases are added in a valid combination, the results of non-linear load sequencing are correct.

Hello Vishal, Both of these programs creates an exported file based on the PXF format. Like other computer formatted files, there is a certain structure to the formatting of information in the file. AutoPIPE then reads this file and creates the a model that is then turned into a DAT file.

Wiki Page: 02. How to model a Sway Brace pipe support in AutoPIPE?
Applies To Product(s): AutoPIPE Version(s): ALL Environment: N/A Area: Modeling Original Author: Bentley Technical Support Group Date Logged & Current Version May. 2016 10.01.00.09 Problem: How to model a Sway Brace pipe support in AutoPIPE? Solution: Sway Brace has a rigid stiffness up to load limit of 1800lb, then stiffness changes to 1800lb/in. The full sway brace resistance load is exerted in the colde condition = free thermal movement * spring + preload Note: There are 2 styles - Mechanical and hydraulic (viscous) sway brace. AutoPIPE models a mechanical. Example: The pipe moves 1.215" under thermal case T1 at node A01 (with inclined support removed), the sway brace load would exert a total 1800 lb/in x 1.215" plus 1800 lb preload = 3987 lbs in the Gravity case. When the pipe fully expands in the thermal T1 case there is zero resisting load in the operating condition Sample model: Sway_Brace_6.dat Insert a inclined support at A01, with 1800 lb /in spring rate Insert > xtra data > concentrated force. Add 2 forces, +ve preload = 1800 in GR and –ve preload in T1 case i.e. gravity case force in same direction as thermal movment and force in T1 case in the opposite direction Add a imposed displacement in the gravity case = the free thermal movement = 1.215” Results show expected full preload = 3982lb exerted on anchor A00 by the sway brace. In the operating case – no load in seen in GT1 at both anchor A00 and A01 support Note: AutoPIPE cannot simulate the arc or pendulum movement of a rigid strut. Typically good design practice limits angulation of struts or hangers to +/- 4 deg One workaround is calculate the lateral restoring force for the angulation for each loading and apply this force at the pipe connection point.

Forum Post: RE: Hinged support
Hello Ivan, Let us consider how the support is restraining the pipe. How tight is the support clamp on the pipe? The pipe is free to move on the vertical plane but cannot move closer to or further way from the wall. At the same time, you have the large uni-strut looking support under the pipe preventing the pipe from moving down. Considering it all: a. no lateral pipe b. no vertical movement down. c. Free to move up d. depending on clamp around pipe, ability of pipe to move axially Seems like a guide support with a large gap up. See AutoPIPE help on supports as recommended below. There will be a chart showing the bearing directions and options available for each type of support. Using AutoPIPE v.11.01.xx.xx and lower there is no support that considers the 'pendulum' effect. This has been logged as and enhancement under: Enhancement 74978: Tracker#:4332 - Analyze the 'pendulum' effect of a support The issue has been logged and places on a list of items to be added to a future version of the application. If you are interested in knowing which version & scheduled date, please log a service ticket referencing the number above.

Forum Post: Ground elevation for wind
Hi What is the meaning of "ground elevation for wind". I went through the help section but still confused. Q.1) I understand it represents ground/datum for wind load considerations, since wind pressure is dependent on elevation of point of interest. Now how to decide reference point to calculate "ground elevation for wind" ? When there are multiple segments, is it represented wrt bottom most point within file or what? Q.2) What is the unit for " ground elevation for wind"? Actually "(mm)" is written in front of this, but nothing appears in RHS bottom unit space. And as per one of the post from "Mr.Seth Guthrie" it is by default feet even for metric units for '09.xx.xx.xx' version. Please confirm.

Wiki Page: 05. How is the ground elevation determined for a Wind load case in an AutoPIPE model?
Applies To Product(s): AutoPIPE, Version(s): ALL Environment: N/A Area: Load Original Author: Bentley Technical Support Group Problem: How to determine ground elevation in AutoPIPE? Solution: AutoPIPE allows the user to create a piping system anywhere within the coordinate system constraints, BUT, how does the program know where the Ground level is unless you tell it! Ground level could be anywhere on the vertical axis: ex. -4000 mm, -125 ft, 0 ft, +30 ft, +86645mm, anywhere, etc…. Just identify vertical level where ground level exists, and anything below that vertical level is considered underground. Anything underground will have no wind applied. Example: Given the following piping system, What value should be entered for "Ground elevation" on the Wind dialog? Do you agree that 10 feet is correct answer? Yes or No... If you had answered YES, you are WRONG. If you had answered "No, need more information" , you are CORRECT. The missing information would be, what is the Vertical elevation of the elbow at the top of the vertical pipe?. From the Point tab of the input grids, vertical axis = Y-axis, one can see that the Vertical coordinate at the elbow A210 = -225.460 Therefore the Ground elevation = -225.460 - 10 = -235.460 ft. Correct !!! Again, baring any Wind Segment settings, any piping above this elevation could have wind applied, but all piping below this elevation would not have any wind applied regardless of Wind / Segment settings.
