Version 3.3.2 Enhancements & Modifications
October 15, 2010
File Import Types – The dialog for File
Import has been modified such that the import of
Piping Component File (PCF format) as well as AVEVA’s
PDMS Pipe Stress Interface file are clearly available
PDMS Stress Interface File Import –
Several improvements have been made in the ability of
TRIFLEX to import the base file format for the PDMS
Pipe Stress Interface tools and export changes made in
TRIFLEX back to PDMS.
PCF File Import – The program has
enhanced its import of PCF file format files used to
interface with a variety of CAD systems including
DescView’s AutoCad Inventor and Plant 3D.
In addition, the piping code now associated
with a PCF import will be that which the user
currently has selected in his Modeling Defaults
Flange Report – The flange reporting
feature of TRIFLEX now has an option as to how the
Equivalent Pressure is to be calculated, either using
Kellogg NB-3641.1 or NRC NC-3851.1.
Chinese Spring Hangers Added – A
selection of spring hangers available from Chinese
vendors, Bergen Power, China Steel, China
Petrochemical, and China GB have been added to the
Spring Hanger Manufacturer window in the Modeling
- Euro Code Material Stress
Allowable – A logical oversight in the
previous version (3.3.1) erroneously assigned a zero
allowable to EN 13480, Euro Piping Code materials.
This oversight has been corrected.
To avoid future material incompatibility, the
switching of piping codes using the Modeling Defaults
Dialog once a piping system has been built is only
possible if all materials are selected from the
- Time History Nodal
Excitations – The dialog and drop down menu
choices for nodal excitation definition in Dynamic
Time History Calculations have been modified to allow
only those choices which the program currently works
upon. The node
list dropdown is now restricted to piping system nodes
only and the excitation type is limited to specifying
only force input.
- Stress Intensification
Factor – The stress intensification factors
for two dimensional components having an In-Plane and
Out-Of-Plane component have been properly allocated to
the calculated moment to which they refer.
- Elbow Restraint Location
– The location of restraints at the mid, far, near,
and specified angular position on an elbow has been
revised such that the Near location is now handled as
3.0 degrees from the beginning of the bend arc.
This is to make it symmetrical to the Far
location which is located at 3.0 degrees from the end
of the arc.
Previously defined at a location of 0.0 degrees, the
location of Near was misinterpreted by the
- Piping Component File
Export – The export of PCF files has been
modified such that the Bend Radius is properly given
on ELBOW and BEND components when using SI, Metric, or
- Expansion Joint with
Pressure Thrust – The Expansion Joint
Deflections and Rotations report is now correctly
reported for expansion joints with pressure thrust
- Material and FRP/GRP
Database Utility – The included utilities for
adding or modifying Generic materials or FRP/GRP
materials has been modified to correctly sort entered
property data on the temperature field before it is
saved to the
- Euro Code Compliance
Dialog – Modifications of allowable stress and
creep rupture stress for Generic and FRP/GRP materials
has been made possible in the Euro Code Compliance
- Material Properties
Evaluation from Euro Code Database – The
manner and type of material property (density,
Expansion Coefficient, and Modulus of Elasticity)
calculations for materials selected from the Euro
Database have been modified, yielding more accurate
- Soil Loading –
Soil loading applied to piping was reapportioned
between primary and secondary effects.
Tab – Occasionally program crashes could occur
if the Piping Code was changed in the Model Defaults
dialog and a component Code Compliance dialog was
brought up without ever having visited the component
Piping Properties dialog.
This problem has been resolved.
Materials in Creep Range – Euro Code materials
in the creep range no longer give the “out of
temperature range” error message when the operating or
base temperature is beyond the elastic limit, as long
as the material is still within the temperature range
where creep analysis can be performed.
- Piping Code Switching
– An error was corrected when a piping system
designed using one piping code was changed to another
piping code and the unit system was other than
would erroneously do a double conversion on the
allowable stress resulting in an extremely low value
being reported in the code compliance dialog.
Ultimate Stress and SMYS – An error in the
automatic calculation of ultimate and yield stress in
B31.8 occurring when properties were re-evaluated
following a change in the process data has been
