TRIFLEX® Windows 1.5.4 Modifications

1.      Find Node Option – In TRIFLEX Release 1.5.3, the find node option for the input data spread sheet was disabled prior to the actual release. In final testing, it was found to not function properly. In TRIFLEX Release 1.5.4, this difficulty has been eliminated and the Find Node Option now works properly.

2.      Code Compliance Data – In previous releases of TRIFLEX, when the User entered the piping model in a random numerical fashion and wished to vary the code compliance data from data point to data point, TRIFLEX, in some cases, did not vary the data in accordance with the User’s wishes. This was sometimes true for cases where mill tolerance, various factors and allowable values were varied on each piping component entered. In TRIFLEX Release 1.5.4, this difficulty has been eliminated.

3.      Stress Intensification Factors for Reducers - In TRIFLEX Release 1.5.3 and prior releases of TRIFLEX, a stress intensification factor of 2.0 was utilized in calculating the stresses at both ends of a reducer for all piping codes. In accordance with the latest requirements of the B31.3, B31.4 and B31.8 piping codes, the Stress Intensification Factors that will now be utilized in calculating the stresses for a reducer in piping systems analyzed in accordance with the requirements of the B31.3, B31.4 and B31.8 piping codes will be 1.0 rather than 2.0. The User may override the default value if desired.

4.      Color Scale Indicating Code Stress Levels – In the final testing of TRIFLEX Release 1.5.3, the color scale indicating the stress levels for the code compliance capability was found to not function properly. In TRIFLEX Release 1.5.4, this difficulty has been eliminated and the Color Scale is now fully functional.

5.      Output Color Mapping - Color mapping of output variables to the piping system, especially for mitered and segmented bends and for underground piping, has been modified to take into account the increased accuracy available given the possibility of a larger number of data points which the calculator imposes on such components.

6.      Multiple Load Case Code Compliance Malfunction – On several occasions when Code Compliance data was not entered by a User for all load cases, TRIFLEX malfunctioned.   This malfunction has been eliminated and the graphic control logic now properly handles situations where no Code Compliance calculations have been performed by TRIFLEX for a particular load case.

7.      Flanges Immediately Adjacent to Anchors – In cases where a flange is modeled immediately adjacent to an anchor, the flange was partially hidden by the anchor in rendered mode. Anchors are now represented so that they do not cover up the attached flange.

8.      Flange Proportions – When flanges were displayed graphically for very large or very small pipe diameters, the proportions were not displayed properly. Flanges are now portrayed in a more realistic manner for all pipe sizes.

9.      Class 2500 Flange in the Flange Loading Report – A User kindly pointed out to us that the Class 2500 Flange Rating category was not available in TRIFLEX Windows for the Flange Loading Report. The Class 2500 Flange Rating has been added to TRIFLEX in this release.

10. Improved Recovery Capability of “.IN” files with Material and Insulation Properties – When a Keyword or .IN file generated by TRIFLEX Windows is imported into TRIFLEX Windows, the data file will now contain material properties, temperatures and insulation properties. In previous versions of TRIFLEX, the temperature, as well as material and insulation properties did not always get translated correctly into TRIFLEX Windows.   In TRIFLEX Release 1.5.4, this difficulty has been eliminated.

11. Improved Recovery Capability of “.IN” files with Joint Components – When a Keyword or .IN file generated by TRIFLEX Windows is imported into TRIFLEX Windows, the data file will now contain joint lengths. In previous versions of TRIFLEX, the joint length did not always get translated correctly into TRIFLEX Windows.   In TRIFLEX Release 1.5.4, this difficulty has been eliminated.

12. Order of Reports displayed on the Pull Down Menu for Viewing Spread Sheet Reports – The order in which the reports available for selection were displayed did not match the order that was available in the pre-formatted report selection dialog in TRIFLEX Windows. In TRIFLEX Release 1.5.4, this inconsistency has been eliminated and the order of the reports displayed on the pull down menu matches the pre-formatted report selection dialog.

13. Piping Code Compliance Reports with Wind Load specified as an Occasional Load - For selected Piping Code Compliance Reports, the Wind Load specified as an Occasional Load Option should not have been available for the User to select. In TRIFLEX Release 1.5.4, this inconsistency has been eliminated.

14. Piping Code Compliance Reports with Wind Load specified with Weight - For selected Piping Code Compliance Reports, the Wind Load specified with the Weight case should not have been available for the User to select. In TRIFLEX Release 1.5.4, this inconsistency has been eliminated.

15. Improved Clarity for the Uniform Load Report and the Wind Load Report – When Wind Loads or Uniform Loads were specified by a User, the report displaying the loads applied to the piping system were reported to be somewhat confusing. In TRIFLEX Release 1.5.4, this confusion has been eliminated.   The System Loads report has been split into two separate reports - the Wind Load Report and Uniform Load Report.

16. Piping System Center of Gravity – The total piping system weight has been added to the Center of Gravity report and, in the graphics view, TRIFLEX now enables the User to automatically place the X-Y-Z adjustable axis at the calculated center of gravity of the model.

17. HASP License Manager for Network Activators - The HASP License Manager used for network activator validation has been updated to reflect the latest changes implemented by Aladdin Knowledge Systems. To insure compatibility with PSI programs, network users should uninstall their current version of the License Manager and install the version included with this release.

18. Chapters 1, 3 & 8 of the User Manual – Chapter 1, Chapter 3 and Chapter 8 of the TRIFLEX User’s Manual have been updated to reflect the latest revisions in the code compliance capabilities now available in TRIFLEX. The revised copy of Chapter 1 is included on the CD and the revised copies of Chapters 3 & 8 are available for download from PipingSolutions’ website. Chapters 3 & 8 will be made available on the release CD containing TRIFLEX 1.5.4 after November 1st.
