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