COMPUTER PROGRAMS

DIPRA has four free computer programs that are useful calculation tools for designing and specifying Ductile Iron pipe. Each of the computer programs is based upon a DIPRA brochure with a similar name. If you do not have copies of these brochures, you may download them at http://www.dipra.org/publications/. The four programs are:

• Design of Ductile Iron Pipe on Supports
• Hydraulic Analysis of Ductile Iron Pipe
• Thickness Design of Ductile Iron Pipe
• Thrust Restraint Design for Ductile Iron Pipe

The DIPRA Computer Programs are available as a downloadable installation file that contains all four of the DIPRA Computer Programs. To install the programs, please follow the procedures listed below.

• Step 1: Save the file attachment to a temporary directory on your hard drive.
• Step 2: Close any running programs, including your Internet browser and mail software (Note: although this step is actually optional, we suggest that you do close all open programs to prevent any conflicts from occurring).
• Step 3: If you have previously installed versions of the DIPRA Computer Programs with a program diskette date prior to 12/11/98, we suggest that you manually remove (uninstall) them from your computer prior to installation of the updated programs to avoid confusion. The new programs cannot remove or overwrite software from an installation diskette dated 12/11/98 or earlier.
• Step 4: From the Windows START button, select the RUN option. In the "Open" blank, please enter the location and name of the program as you saved it to your system (for example, if you saved the file into the "Windows" "Temp" directory on your "C" drive then you would enter "C:\Windows\Temp\dipra.exe" in the blank provided). Press the "OK" button.
• Step 5: Follow the onscreen installation instructions to complete the installation of the programs.
• Step 6:  View or print the program documentation.  The directory into which you chose to install the programs (by default "C:\DIPRA") will contain the documentation as an Adobe Acrobat "pdf" document (progdoc.pdf).

If you encounter any problems with the installation or use of these programs, please let us know. Thank you for your interest in our programs – we hope that you find them to be useful tools.

NOTE 1: These programs have not been tested for use on Windows NT or other networked computer systems. If you install to a system of this type, we would appreciate hearing from you regarding the functionality of these programs.
