Version 3.2.1 Enhancements & Modifications
Decomber 9, 2008
1. PCF Export –
In addition to the ability to import a PCF formatted data file into TRIFLEX, this release allows
the program to export a PCF formatted file as well, establishing a two-way communication with a
variety of CAD and plant management programs.
Adding to the versatility of
1. B31.3 Database Update –
The B31.3 database has been updated to reflect higher allowable for A106 and A53 steels
as given in the 2006 revision of the piping code.
2. Structural Steel Database Rearranged –
The order of listing the rectangular structural tubing in the structural steel dialog shape
selection box has been refined such that all rectangular tubing is displayed together
followed by all square tubing.
3. Structural Steel Automatic Selection –
When coding multiple lengths of Structural Steel, the type and shape fields will now be
inherited from the previous entry, rather than reverting back to W6x16.
4. Celsius Temperature Limits on Materials –
Since the majority of database material properties are given in terms of degrees Fahrenheit,
a rounding error precluded using an installed or operational temperature equal to the
temperature limit if the Celsius temperature scale was selected. In order to mitigate
this problem, a one degree leeway is now allowed on either the maximum or minimum
temperature limits of code materials. If a temperature is specified to be some fraction
of a degree beyond the actual temperature limit of the material, the properties will be
selected as the properties at that limit, rather than extrapolating beyond.
5. Material Cache Reset –
The material cache reset function has been revised to work more efficiently and, when a data
file earlier than that saved with version 3.2.0 of TRIFLEX is read in, the reset is done
automatically upon reading in the file. This will assure that older data files will be
updated to the latest database values, rather than older or outdated information that
may have been saved with the original data file.
6. Material Density and Weight Calculation –
An error in processing material density when non-English units were selected has been corrected.
This error manifested itself when the material density edit box was clicked on and regained
the focus multiple times, each time trying to do another unit conversion on the value displayed.
7. Invalid Argument in Material Selection –
Occasionally when using the Piping Code Button to bring up the material data base material
selection dialog, an “Invalid Argument” error message would be encountered.
This has been corrected.
8. PCF Import Coordinate Snap –
Minor inconsistencies in producing PCF data files may lead to very small coordinate differences
between nodes which should be and were intended to be connected and at the same coordinate
location. Previously, on import of such a data file, TRIFLEX would see the coordinate
difference, flag it as a disconnected piping system, and place a new anchor at the beginning
of the disjointed branch. Now TRIFLEX will snap the coordinates to the same location and
join otherwise disconnected branches if the coordinate mismatch is less than 0.1 mm in metric
units or 0.01 inch in English units.
9. Pressure Relief Valve with User Specified Piping –
The pressure relief valve would produce a graphic error if the non-standard, user specified
pipe was being used to route to or from the valve. This problem has been corrected.
10. API 610 Reports –
The API 610 reporting routines have been modified to handle pipe sizes unsupported by the
code and to provide a more consistent display of warning messages.
