NTRODUCTION

AutoPIPE is a stand-alone computer aided engineering (CAE) program for calculation of piping stresses, flange analysis, pipe support design, and

equipment nozzle loading analysis under static and dynamic loading conditions. In addition to 30 piping codes, AutoPIPE incorporates ASME, European, British Standard, API, NEMA, ANSI, ASCE, AISC, UBC, and WRC guidelines and design limits to provide a comprehensive analysis of the entire system. AutoPIPE V8i is available for Windows XP, Vista and Windows 7 and can be licensed across networks.

There are three editions of AutoPIPE: Standard, Plus, and Nuclear. The Plus version offers several advanced analysis capabilities not available in the standard version which are detailed later in this chapter. The nuclear edition includes all Plus features and nuclear ASME in class 1,2,3 and thermal transient analysis. A KHK2 add-on option is also available for the Plus version that allows use of the Japanese KHK Level 2 piping code in addition to all the features of the Plus version. AutoPIPE is a proven, well-established program that has been commercially available since 1986. AutoPIPE’s rigorous quality assurance practices have withstood numerous on-site audits, making AutoPIPE one of the few PC based piping programs approved for use in nuclear safety applications.

OVERVIEW

O

Developed to meet the needs of companies involved in industrial piping system design, AutoPIPE utilizes Windows-standard commands, object oriented graphics technology, and CAD interfaces to enable users to create, modify, and review piping and structural models and their results quickly and easily.

A graphical representation of the model is displayed as it is being developed, providing instant visual feedback. AutoPIPE performs extensive error checking as the data is being entered and alerts the user if the model does not comply with the regulatory standards of piping design.

Using AutoPIPE’s object oriented graphical select options, users can insert, delete, or modify pipe properties, supports, or offsets across an entire range of points with one command. Graphical selection of ranges is also used for cut, copy, & paste operations.

S

The following is a partial list of the features and capabilities of AutoPIPE. Refer to the on-line help for a complete reference of features and functionality.

P

C

L

AutoPIPE contains a comprehensive and extensible library of material properties and piping & structural components including pipes, reducers, tees, valves, flanges, beams, flexible connectors and other items. Supports include: anchors, spring and constant force hangers, one-way restraints, limit stops, guides, snubbers and tie-rods.

The material library includes temperature dependent properties and code dependent allowables. AutoPIPE provides component libraries for ASME/ANSI, JIS, DIN, and Nordic standards.

H

D

AutoPIPE performs spring hanger design for one or more operating conditions. The program selects hangers from a customizable manufacturer's library, which includes: Grinnell, Bergen-Patterson,

FEATURE SUMMARY

structural system, and end releases to model pinned connections. AutoPIPE’s unique two point support elements allow the user to define the connection between pipe and structural steel using gaps and friction at the same point if required.

The AISC structural library with cross sectional properties and a database of properties of commonly used structural steel materials is included within AutoPIPE. Users can easily define their own beam elements and steel materials to model beam elements not included in the AutoPIPE’s database.

Frame structures are created and modified in interactive mode using AutoPIPE’s graphical interface. In this manner, users can graphically copy, paste, or modify structures with one operation using AutoPIPE’s graphical select options or by clicking on a particular beam element.

N

-L

A

O

AutoPIPE provides directional supports, gaps, friction, bilinear spring supports and nonlinear buried pipeline analysis. Users can specify both gaps and friction at a support point to simulate real world boundary conditions. AutoPIPE provides 2-point restraint functionality to define tie rods with gaps, pipe/structure interaction, and other connectivity between any 2 points in the system.

AutoPIPE provides unique capabilities for nonlinear load sequencing. Users can, for example, specify that wind, seismic, or other occasional loads are analyzed in sequence immediately after the gravity load or specify that the occasional loads are analyzed after thermal. In this manner, users can accurately calculate loads and stresses for occasional loads acting on the operating position of the piping or the ambient position of the piping. Load sequencing options also allow the user to calculate gravity and thermal loads using nonlinear analysis and seismic loads using linear analysis (as

recommended by UBC and other design standards) in the same run.

L

AutoPIPE provides a link to WinNOZL for calculations of local shell stresses per British Standard 5500, Welding Research Council bulletin 107, 297, and 368, using stress allowables and load combinations as specified by ASME Sec. VIII, Div. 1 and 2. Various piping load combinations on tanks can be examined in accordance with the API 650 code.

Further, AutoPIPE provides unique options for hillside nozzles and reinforcing pad calculations. These are available for cylinders, spheres, cones, semi-ellipses, and torispheres. The automatic importing of AutoPIPE piping loads saves time and minimizes user errors.

F

AutoPIPE is a finite element program used to analyze piping and structural systems subjected to static and dynamic loads. Use of intelligent defaults allows the user to analyze complex systems without in-depth knowledge of finite element theory.

FEATURE SUMMARY

D

A

Dynamic analysis capabilities include mode shapes and natural frequencies, response spectra, phased harmonic load analysis, time history dynamic analysis and force spectra analysis. For modal analysis, AutoPIPE can automatically insert mass points along elements. Missing mass and zero period acceleration may be applied in dynamic analysis. AutoPIPE satisfies NUREG/CR-1677 benchmark problems and provides built-in NRC spectra, seismic anchor movements, and code case N411 capability.

AutoPIPE provides built-in fluid transient synthesizers for calculation of waterhammer, steamhammer, and relief valve forces, which are integrated with time history dynamic analysis, and special thermal bowing analysis for partially hot filled liquid pipelines. Utilizing the Bentley PULS program, users can calculate flow induced vibrations, or pulsations associated with reciprocating equipment, and

automatically transfer those harmonic loads directly into AutoPIPE to calculate dynamic piping responses.

P

P

After analyzing a system, users can click on the graphics model to instantly view stresses, loads, deflections, or mode shapes at any point. Color coded stresses, animated vibrations, and pop-up windows enable the engineer to more quickly identify and investigate critical areas without having to review a voluminous amount of batch output data.

Output report options allow users to pick and choose which reports to generate, with or without filters, for on-screen review or printing. Code stress combinations are performed automatically. Unique filter options allow the user to generate custom output reports based on user-defined stress, deflection, or load criteria. AutoPIPE enables users to analyze multiple thermal, wind, seismic, wave, and dynamic loads all in one analysis with Min/Max load summaries.

Using AutoPIPE’s graphical select options, users can graphically select points to be included in the output report. As an example, a user could generate an output report for only 2 points in a 1,000 point model.

This chapter provides you with a tour of the AutoPIPE interface, and walks you through several of the most basic tasks from opening a model and defining a new system to placing a few components. If you are a new user, you should carefully review the discussions of selecting points, specifying ranges, and inserting components. Veteran users who are switching from DOS to the Windows edition of

AutoPIPE should also note that the new interface allows for many tasks to be performed graphically rather than through a series of keystrokes.

This Chapter introduces you to the most basic AutoPIPE tasks, including:

Starting AutoPIPE: Double-click on the AutoPIPE icon (or select it from a taskbar)

Loading a system model: The first step in every AutoPIPE session is either to define a new system

model or load an existing one.

Navigating the interface: This section covers basic interface navigation techniques and introduces

you to the program interface, menu structure, and command techniques.

AutoPIPE Modeling Concepts: When modeling in AutoPIPE it is important to understand some of

The first step in creating a new model is to name and define the model as described below: 1. Select File > New to open the New dialog shown below.

2. Indicate the path where the file will be stored using standard Windows file selection techniques (i.e., highlight the appropriate drive, then the directory where the file will be stored).

3. After the path information is specified, type the name of the model in the File name field, and then press Save.

Note The next several steps will present a series of dialogs for the definition of the model and its operating parameters. Each of these dialogs is discussed briefly below for the purpose of demonstrating the sequence of steps required to create a new model. In the next chapter

LOADING A MODEL

4. The General Model Options dialog is displayed as shown below.

Complete each of the fields to adequately describe your model. Of particular note is the Piping Code selection list, which allows you to choose from a variety of pre-defined piping codes. After completing the dialog, press OK.

Note You can set SI units to be your default units by copying the SI.UNT file in the program folder into AUTOPIPE.UNT file. You can also use DIN sizes by selecting AUTODIN as the component library.

5. The Segment dialog is displayed for the definition of the initial segment that will be used as the starting point of your model. Define the starting point name, any offset values, and a pipe identifier that will be associated with all components that belong to that segment. As components are placed on the line, point names are generated. The default point names always begin with the segment name (“A” in the example below) to which they belong. After completing the dialog, press OK.

LOADING A MODEL

6. The Pipe Properties dialog is displayed. From this location you define the initial pipe properties of the model. This dialog will be explained in the next chapter. After completing the dialog, press

OK.

7. The Pressure & Temperature dialog is displayed for the definition of operating loads. Enter values in each of the fields as required by the demands of your system, then press OK to close the dialog.

8. The setup of the new model is complete. You can now add a component to the first point (A00) in the system (or insert an offset distance from this point). In the next chapter, we’ll create a new model and demonstrate methods for placing and connecting components.

Dialogs present and request information.

Press OK to accept the values in a dialog

Some fields have an associated list of options from which the user can select. For example, there is a limited set of piping codes, and the user can always select the appropriate code from a list when the cursor is in the Piping Code field. This list is contained inside the dialog itself, and is opened by pressing on the adjacent to that field.

The units that apply to a particular field are displayed in the status bar in the bottom right hand corner of the screen.

To advance from field to field in a dialog, press the Tab key. Pressing Enter from the dialog is the equivalent of pressing OK. You can also advance the cursor by simply using the mouse to select the desired location.

Options which are toggled ON are indicated by a . Positioning the cursor in that field and then pressing the left mouse button toggles the ON/OFF state.

Press F1 key on any dialog field to obtain help on a particular field or parameter. To obtain “big picture” dialog help, press the Help button.

As you move from field to field in a dialog, the units that apply to that field are listed in the status bar in the bottom right hand corner of your screen. To accommodate the varied needs of our users, AutoPIPE allows special characters to be used to decipher the field format and convert these to decimal equivalents. The types of input which are allowed when inputting English units are illustrated in the table below:

All AutoPIPE commands can be accessed from the menu system. For a detailed description of the capabilities and functionality of a specific command, refer to the AutoPIPE On-line Help Menu

Reference. The top menu that is displayed above the drawing area depends on the current mode of the

program:

The standard Menu is displayed when building or editing a model

AutoPIPE can be placed in a Worksheet Mode, which displays a model’s data in spreadsheet format.

Note that each of these menus has a toolbar associated with it.

T

AutoPIPE has three types of toolbars: command, view and components. Command toolbars are always docked directly beneath the main menu, and cannot be moved from this location. The component and view toolbar, on the other hand, can be moved from its position along the right and left side of the screen respectively and positioned as a “floating toolbar” in the modeling area of the screen. To reposition it, simply “drag” the title bar of the toolbar into the screen area. The toolbar will resize.

Hint If you forget the use of a particular button, position your cursor over it and wait a second or two. A ToolTip description is displayed beneath the button.

H

A number of AutoPIPE commands can be accessed directly from the keyboard using hotkeys. In AutoPIPE hotkeys are executed by holding down the control and then pressing a letter key. Additionally, AutoPIPE also uses the function keys for some operations. Note that these hotkeys are displayed in the AutoPIPE pull-down menus next to the item it executes.

PIPE

Experienced users of AutoPIPE have come to appreciate the speed and efficiency with which detailed, data-rich models can be created, modified, and reviewed. If you are a novice user, it is important to understand some basic concepts of the program.

Models are created from individual pipe segments

Components are attached to the active point (cursor location)

AUTOPIPE MODELING CONCEPTS

Each piping system is divided into a number of segments. As an example, the sample model shown below contains five segments labeled A through E. Piping models are entered into the program, segment by segment. They may be extended or modified at any time by either adding more segments or changing existing ones. The segments are labeled automatically (A through E in the example). If more than twenty-six segments are entered, the additional ones are labeled AA, AB, AC and so on.

Although most of the piping segment definition is handled automatically with AutoPIPE, in some circumstances it is advantageous to plan the model in advance and divide it into logical “segments” before creating the system (see ‘Rules for defining Pipe Segments’). Typically, a segment would begin and end at anchor points or a branch connection. However, as shown in Figure 2-1 on the facing page, at point D02, a pipeline may be divided into two or more contiguous segments. Whenever a tee/branch is inserted, AutoPIPE automatically assigns a new segment identifier. Each new segment begins with a different alpha character, making it easier for node numbering and easier to keep track of segments when reviewing input listings or output results.

When defining a new system, AutoPIPE automatically displays the first Segment screen (the first segment is segment A). In this screen, the user must specify starting X,Y, Z coordinates of the Segment and input a Pipe identifier name. A Pipe identifier is used to assign properties. The Pipe identifier can be any name that the user wishes to use. It is a good idea to choose a meaningful name such as the first few letters of a line ID or something like 8”std (indicating 8” nominal diameter, standard schedule wall thickness) to help you keep track of pipe properties when reviewing the model.

These properties will be applied to all components attached to that pipe identifier until otherwise specified by inputting a new pipe identifier name in one of the component dialogue screens. After inputting a new Pipe identifier name, the Pipe properties dialogue screen will automatically be displayed for input. For example, if you define a Pipe identifier as a 4-inch line, then all following components will default to those same properties until the user types in a new Pipe identifier name on a component dialogue. A segment can be made up of multiple pipe identifiers.

Existing Pipe properties can be easily modified using either Modify/Properties of Pipe Identifier (which modifies that Pipe Identifier throughout the entire model, wherever it was used) or by graphical selection of a range of points and Modify/Pipe Properties Over Range.

Note AutoPIPE makes extensive use of dialogs to obtain user input. A discussion of techniques for navigating throughout the fields of a dialog is provided later in this chapter.

A number of rules govern the definition of piping segments; they are listed as follows:

1. Each segment has a forward and backward direction and is entered as a sequence of points. AutoPIPE automatically keeps track of the local axis of the segment, making it convenient to insert intermediate points or components using the Length field. These points are automatically assigned alphanumeric names (which the user can override), with a maximum of four characters each. For example, in Figure 2-1, segment B is defined by points A03, B01, B02, B03, B04, and B05, all of which have default names. The default increment in point names is 1. This increment can be changed under Tools/Model Options/Edit. AutoPIPE can automatically renumber point names after editing using the Renumber button or Edit/Renumber.

2. Wind loads and Hydrotest can be turned on and off on a segment by segment basis, so keep that in mind when creating your model. Also, AutoPIPE provides options to view the model, graphically select, delete, or view output results on a segment by segment basis.

3. Global coordinates must be entered for the first point of the first segment (default global

coordinates of Segment A is 0,0,0). AutoPIPE automatically displays the first segment screen for the user. This is point A00 in the example. Then, each point along the segment is typically located by offsets from the preceding point, until the whole segment has been defined (e.g. points A00 to A06 for segment A).

4. Subsequent segments typically begin at points which have been defined previously (point A03 in segment B is an example). These points are either branch points or continuation points (see #6 below). Since these points have already been defined, entering coordinate data for them is not necessary.

5. Although Subsequent segments typically begin or end at an existing point, this is not necessary for the program to function correctly. It is often more convenient to start a disconnected segment in space using Insert/Segment or clicking on the Segment button, typing in the name of the first point (in this case, make sure that the name of the first point on the segment is not the name of a previously defined point), and assigning the starting X,Y,Z coordinates of that new Segment. For example, it may be more convenient to define suction and discharge sections as disconnected segments without having to model the equipment (see Pump Modeling Example in AutoPIPE on-line help). Also, the ability to handle disconnected segments is a big advantage when importing sections from a CAD model.

6. A continuation point is established when a new segment is defined to begin at the end point of an existing segment (see point D02 in the Figure 2-1). This is typically done to divide a long length

AUTOPIPE MODELING CONCEPTS

When defining a segment, proceed from point to point along the segment. Check that everything at the current point has been specified before moving on to the next point.

G

T

E

In previous versions of AutoPIPE, users would have to insert a new segment at an existing run point in order to insert a tee branch connection. With the new Tee element, this procedure is no longer required (although users can still input a tee branch by inserting a segment at a run point if desired).

The Tee element automates the insertion of tees and includes the offset distance from the previous point. For example, if a user wishes to insert a tee point on a header 5 feet away from his current point (active point), he clicks on the Tee button or Insert/Tee and inputs an offset of 5 feet as well as the tee type information for stress intensification purposes. The Tee element will automatically assign a new segment once the user begins to input the branch. AutoPIPE will keep this point a tee for stress intensification, even if the user does not create a branch. In some cases, users may choose not to input small diameter vent or drain pipe branches, but still want the stress intensification factor at the tee connection point. AutoPIPE displays a graphical symbol at Tee points enabling users to visually review tee locations. Users can also click on Tee arrows to easily switch between the header and branch side of the tee.

Users can convert an existing run point to a Tee using Modify/Convert point to/Tee command.

P

After defining and inserting a segment, you’ll notice that a small crosshair appears in the drawing area. This crosshair represents the currently active point. The active point is also displayed in the status area immediately below the drawing area.

When placing components, you should remain aware of the active point. After selecting a component type for insertion, AutoPIPE will automatically assume that you want the starting point of the

component to be inserted at the active point. By default, AutoPIPE will increment the point to the next value and concatenate this with the letter that defines the current segment. For example, if you are inserting a run point on Segment A that contains nothing but an anchor point, the Run Point dialog will contain the value A01 in the Name of Point field.

To designate an existing point as the active point, simply click on it with the mouse. The crosshairs should redisplay over that point and the Active Point status area should reflect the new point as well. In a complex model, you can click on the Go To Point button and type in your desired active point

AUTOPIPE MODELING CONCEPTS

location. You can also use the arrow keys to control the location of the active point as described below.

It is important to note that a given point may have two or more different segments. For example, in

Figure 2-1, point A03 is a tee connection point, and is made up of point A03 segment A and point

A03 segment B. The active point name and segment location is displayed in the bottom right hand corner of your screen. In order to toggle between multiple segments on the same Point location, it is usually more convenient to use the up and down arrow keys (see following section on keyboard commands).

C

As an alternative to the mouse, the “Active Point” crosshairs can be controlled using the keyboard.

KEY TASK

Move to the next point in the current segment (forward segment direction).

 Move to the previous point in the current segment (backward segment direction).

When at a segment junction, move to the next segment that connects to the current point (more than 2 segments are possible).

When at a segment junction, move to the previous segment that connects to the current point (more than 2 segments are possible). Move to the first point of the next segment.

Move to the last point of the previous segment.

Move to the next intermediate soil point for the current soil region. Move to the previous intermediate soil point for the current soil region.

Use one of the techniques below to delete existing points or components:

Select the unwanted component with the mouse then press the Delete key on the keyboard.

Select the unwanted component then press the Delete button on the command toolbar.

Position the cursor on one of the points, or select a range of points, then hold down the [Shift] and right-click the component to be deleted from the toolbar.

Graphically select a range, then select the corresponding component name from the Delete menu to delete across an entire range of points with one command (see Selecting a Range).

Select the unwanted component then select the Edit/Delete menu command.

Select it with the mouse or position the active point at that location, then select the corresponding component name from the Delete menu.

Select the appropriate row in the Input Grids and Press the Delete key on the keyboard. Note: Multiple rows can be deleted at time.

Selection of ranges is a powerful tool within AutoPIPE that users should become familiar with. By graphically selecting ranges of points, users can insert, modify, or delete components, properties, loads, and other data across ranges of points with one command or graphically select points to be included in the output reports. Also, selection of ranges is required in order to graphically cut, copy, or paste.

There are several methods available to graphically select ranges of points. By using buttons or the

Select menu or Input Grids, users can select by a number of different criteria such as by segment, point

names, component type, pipe diameter and other parameters. In addition, users can create a mouse zoom box Window and click on the Select all points in Window button to select a range. Another common method used to select a range is to click on the first point in the range, press and hold the

[Shift] key, then click on the last point in the range. The selection set will highlight in red. This is the

same technique used to select ranges in Word, Excel, and other popular Windows programs.

To create a selection set that includes components that are not part of a contiguous run, use the [Ctrl] key as follows: To add more components to this set, or delete points from this set press and hold the

BASIC TASKS

[Ctrl] key and select additional elements. The [Ctrl] selection method allows you to select a set of

components that are not continuous. Alternatively, Select/Point enables buttons that can add or subtract from the selection set on a point by point basis.

The Select/Range command, another method of creating a selection set, allows the user to input “From” and “To” points inside a dialog.

In any Input Grid Tab, select a group of rows or cells (same column) using [Ctrl] or [Shift] keys will highlight the selected points in red on the graphic. Note: The point symbol and names will be highlighted when selecting from the Points or Pres/Temp/PipeID Tabs. These two tabs enable selection of all points in the model. The Pres/Temp/PipeID Tab also provides a range selection up to and including the bend near or far points. All other grid Tabs will highlight the component symbol and the thermal anchor movements tab will highlight the anchor symbol on the graphic.

When a new system is created, AutoPIPE automatically presents a series of dialogs that allow you to establish the piping code, pressure and temperature loads, pipe materials, and other factors. This section guides you through the completion of each of these dialogs.

Note Before beginning this exercise, you may want to create a directory on your local drive where the tutorial model can be saved.

1. Select File > New.

2. The New dialog is displayed. Navigate to the Examples directory, type TUTOR1 in the File Name field, then press Save.

Note By default, the file is saved in the same directory where AutoPIPE is installed. If you’d prefer, save the tutorial model in a separate directory.

3. The General Model Options dialog is automatically displayed. For the first tutorial model, let’s discuss some of these areas in detail. First, input the following values:

CREATING A NEW SYSTEM

4. AutoPIPE filters many of its dialogs based on the Piping Code to ensure code compliance and to help you properly identify various elements of the system. Select B31.3 Process from the Piping

Code selection list (press the down arrow next to the field to open a list of the available codes). 5. Notice the Vertical Axis field. AutoPIPE models are constructed in three-dimensional space, which

means that you must be aware of three direction vectors. By default, the vertical axis will be set to the Y-axis. However, if you’d like to customize the vector that is considered to run in the vertical plane, you could change this value. For our model, accept the Y-axis default.

6. The next field of interest is the Number of Thermal/Pressure Cases. In order to define two thermal/pressure cases for analysis, input a value of 2 in this field.

7. There are several methods for navigating within AutoPIPE dialogs. You can use the mouse to position the cursor in a field, or press Tab to jump to the next field in sequence. For example, press Tab now to jump to the Ambient Temperature field, which contains a value of 70°F {21.1°C}. After this field is highlighted, examine the status bar at the bottom of the AutoPIPE application window. The lower right hand corner will always display the units associated with the active field. In this case, the status field reads deg F. A brief glance at the Units area of the status bar will

CREATING A NEW SYSTEM

always help you to confirm the units associated with the active field. Accept the default Ambient Temperature value of 70 {21.1}.

8. Press OK to close the General Model Options dialog. 9. The Segment dialog is automatically displayed.

The Segment dialog allows you to assign a name and starting location for the first pipe segment to be placed in the model. Accept the (0,0,0) global coordinate default for the first segment (A). The next step is to assign a Pipe Identifier to this segment. A set of pipe properties can be defined and associated with a named ID. It is a good idea to choose a meaningful pipe identifier name such as the first few letters of a line ID or a descriptive name. In our example, we will use 12”STD

{300STD} to indicate a 12"{300mm} nominal, standard schedule wall thickness. Input 12"STD {300STD} in the Pipe data identifier field then press OK.

10. The Pipe Properties dialog is displayed. Note that 12”STD {300STD} automatically appears in the

Pipe Identifier field of this dialog. These properties will be associated with all components
