CAEPIPE is a versatile programfor solving a variety of piping design and analysis problems in several industries such asenergy, process and caepioe.


CAEPIPE performs linear and nonlinear static and dynamic analyses of piping systems byimposing a variety of loads such as dead weight, thermal, seismic, wind, spectrum, timehistory, harmonic, etc.

It calculates displacements, forces, stresses, etc. Extensive graphical display capabilities to amnual, pan and rotate theimage and see the model from different viewpoints make the program very useful.

It animates deflected and mode shapes and shows color-coded stress contours. It uses advancedWindows programming techniques such as intelligent repainting, scroll caepiep tracking,multithreading, memory-mapped caeplpe for faster data access, among others, to make yourjob easier and faster. Also, every effort is made to keep the program and data file sizessmall. Many thoughtful and useful details in the program allow you to work more productively.

Forexample, you can annotate your model with copious comments to enhance documentationof the model, or duplicate repetitive input or rotate sections of the model with one operation.

CAEPIPE does not confuse you with unnecessary buttons on a toolbar, caeplpe contains onlythe most frequently performed tasks. The keyboard shortcuts, too, are designed to makeyou more efficient and effective. Wewant you to benefit from it by making full use of the softwares features by exploring theprogram and contacting our friendly and knowledgeable support staff. If you have questions or comments, caepipf email them to: An alphabetically arranged technical Reference section, and3.

The manual ends with an index. Two important tasks need to be done after you connect thehardware key securely to an Mznual port or a USB port of your computer. Install the hardware key driver and server from Rainbow Technologies.

Feel free to browse through the contents and install whicheveris required, or contact our support staff for assistance. You will be shown anotherwindow similar to that shown below on the right. You will now see the following majual screens one after another where you are askedthe usual installation questions. You must accept the terms of the License agreement by clicking on Yes before proceeding. Once you have picked your choices, you can now begin installing or use the Back button toreturn to previous screens to change your choices.


Layout, Graphics, List and Results. Each is an independent window with its ownmenu and toolbar. Some of the commands have keyboard shortcuts.

They are shown in the online Help. File MenuThis menu contains commands to open files and set user preferences. Open last model Enter Caaepipe last model Enter This command can be quite useful when you need to open repeatedly the same model.

Simply pressing Enter from the Main window will open the model for you. There is noneed to go through the Open File dialog. Preferences command has three tabs – Backup, Fonts capipe Toolbar.

BackupMake backup copyWith this checked, everytime you save your model, the previously saved model data iscopied to another file backup file that is named model.

You can select the locationwhere you want these files saved click on Folder. Rename the file to somename. A new model will besaved to untitled. In the event of a computer system crash, the most recently saved data can be retrieved.

Locate the file model. Folder FolderSelect any folder to which you as a user have write permission. MOD that you open is located. Graphics GraphicsSelect a font face and size to use inside the Graphics window.

Large buttonsThere are two sizes for toolbar buttons. Selecting this command will show the toolbar withlarge buttons. Our support staff might ask for this information when you contactthem for support. Also from the About dialog, you can access the SST web site by clicking on www. For yourconvenience, the Open Results dialog shows the results file for the currently opened modelif it is already analyzed, if not, the name of the last opened results file is filled in the namefield.

You could change the selected printer and customize other settings in the Printer tab shownnext. At the end ofanalysis, you are asked whether you want to “View results?

This information cannot be modified in the Resultswindow however it can be printed in Results. The appropriate dialog is shown. To delete a range of rows, you must select the Deletecommand from the Edit menu, and then type the row numbers to set the range for deletion. If you want to delete till the end of the model, either type in a big number for “To ” suchas or type in the number of rows shown in the title bar in parentheses. Split SplitUse this command to split a straight element or the straight portion of a bend into two parts.

This can be useful to create nodes for supports or applying forces at intermediate locations. To split curved portions of bends including jacketed bendsspecify intermediate nodes atdesired angles in the bend dialog.

When you have a long sloping pipe, you can create one long element with the slope builtinto it and use the Split command to break it down into smaller elements. Or you could usethe Slope command.


The main function is to calculate automatically the offsets for a sloping element that isnot aligned along one of the major global axes.

When a pipe slopes or is routed at anangle with respect to the global axes, it becomes necessary to calculate the offsets DX,DY and DZ using those faithful sine and cosine functions.

But, therein lies the problem. Sometimes, calculations might get tricky and time-consuming. Let us see a few examples. A 20 line in the XZ plane, 10 feet longMethod 1: Find direction cosines DCs for the line vector.

Direction cosines are simply cosines ofthe angles the vector makes with the global X- Y- and Z-axes. Cosines of these angles are: SelectSlope from the menu, enter these numbers into the X comp, Y comp and the Z compfields of the Slope dialog that opens up, and type the length, 10 ft.

Once you input the slope, follow this pipe with other elements down the line by inputtingdifferent lengths while you retain the same direction cosines.

A 40 line in the X -Y planeMethod 2: Find direction cosines, if the line is at 40 deg. So, the DCs are: Type these DCs and a length into the Slope dialog. More information about Direction cosines is available under the section on Direction Reference. ExampleLet us rotate the branch line of the familiar Sample model.


The branch line is betweennodes 30 to 80 rows 8 to 11 in cepipe Layout window. Say, we wanted this branch line to berouted in the -X direction i.

Notice the rotated offsets now they are in the -X direction. One thing to note: The valve additional weight is shown in the negative direction becauseof the rotation. You are asked for the range when you select this command from the Edit menu.

Itbecomes really useful when you have a big model and want to adopt a consistent nodenumbering system throughout after multiple edits.

You can renumber all or parts manuap thesystem. Before using this feature, please make a copy of your model and work on the copy. This can be easilydone. Changing header node numbers: The Renumber Nodes dialog will open.

SST Caepipe English version 7.0 fully functional pipe stress analysis software

In thedialog, type in: Changing branch line numbering: The final layout looks like the following. Other reasons you may want to use the Renumbering feature: In a big model, multiple edits sometimes bring about confusing node numbering. Usethis feature to organize the numbering system. You may need to follow a system for numbering just to make parts of the system easilyrecognizable; all branch lines could get node numbers greater thanall bypass linescould get node numbers greater thanand so on.

This is a powerful feature that makes you more productivewhile modeling.
