TRIFLEX® Windows Version 2.3.0 Enhancements & Modifications
July 14, 2003

Enhancements

1. B31.5, ASME Refrigeration Piping and Heat Transfer Components Code – This release of Scandinavian Piping Codes – This release of TRIFLEXâWindows corrects an error that resulted in a system malfunction when viewing the piping code report for the Scandinavian piping codes, TBK51, TBK52, SPC1, and SPC2.

2. Pressure Relief Valves – An additional component type, a Pressure Relief Valve, is added to the component toolbar and may be included directly in a piping system without interpretative modeling. An associated database of representative valves is also included.

3. Graphical Vessel Representation – When the piping system originates or terminates at a vessel, TRIFLEXâWindows now provides a graphical representation of the vessel instead of a rectangular block specifying an anchor. A tab on the anchor dialog brings up a user interface, allowing the specification of vessel properties, including size, orientation, and attachment data.

4. Rupture Disk – The flange dialog now allows for the specification of a Rupture Disk for which a flange pair will model the holder. For calculation purposes, a disk thickness and weight is added to the flange weight and length data.

5. B31.1 Material Database – The complete material database from the ASME B31.1 piping code is included in this release of TRIFLEXâWindows. Selecting a material in the database when using the B31.1 code automatically enters material modulus of elasticity, thermal expansion coefficient, density, and allowable stress at the appropriate process temperature.

6. PCF Import – The program now allows the direct import of PCF files as produced by Alias Limited’s I-Sketch isometric drawing program. Piping systems entered using Alias’s tools including field data entered on PDA using I-Sketch Field, may be directly imported and analyzed with TRIFLEXâ.

7. DXF File Export – Three-dimensional DXF files compatible with a variety of drawing programs, including AutoCAD, may now be produced from within the program. The drawing produced is a line model, typical of piping isometrics, with dimensional data included.

Modifications

1. PDS Import of Eccentric Reducers – This release of corrects a problem with specifying eccentric reducers when importing PDS files into TRIFLEXâWindows. Such reducers are now shown properly in the graphical representation of the piping system and are correctly passed to the calculation engine.

2. Graphical Representation of Eccentric Reducers – When eccentric reducers were rendered in previous versions of the program while modeling a connection from a small diameter pipe to a larger diameter one, the graphical representation was offset. This situation has been rectified.

3. Renumbering of Large Selection Sets – Previous versions sometimes encountered difficulty in renumbering large selection sets containing multiple branches. The renumbering algorithm has been corrected, making it more stable in such instances.

4. Intermediate Node Locations on Elbows – When large radius elbows were modeled in previous versions of the program there could be only a single intermediate node specified. Nine such intermediate nodes are now allowed, increasing the precision with which elbow stress calculations may be performed.

5. Autosave Dialog Revised – The dialog for the autosave functionality within the program was revised to allow more space for entering possibly long path names.

6. Export to isoOut Files – Export to isoOut files for interchange with Nor-Par Online Systems’ Smart Stess Iso program are no longer allowed for cases in which a code report is not requested or a valid code report is unavailable.

7. Mixed Unit Input Corrected – Previous releases of TRIFLEX used the “DIAMETER” unit to calculate piping system displacements. This caused a problem in Metric, SI, or IU1 units when the user wished to input pipe diameter in inches, but desired movement results in the selected unit system. A separate category, the “MOVEMENT” unit, has been incorporated into the program to resolve this problem, such that system movement and pipe diameter units are no longer related.
