Windows 2.2.1 Enhancements & Modifications
February 26, 2003
1. 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. Structural Tubing and Pipes – The input dialog
for user defined sizes of Structural Rectangular and Round
tubes erroneously listed the English or Imperial unit for
sizing as feet but did all cross sectional property and
subsequent calculations based on the input as if it were
given in inches. The unit, as it appeared on the dialog,
should have been inches and is corrected accordingly.
3. Spreadsheet Component Exchange – When components
were moved on the input spreadsheet due to rearrangement
or insertion, occasionally the component being replaced
was not totally erased before the new component, replacing
it on that row of the spreadsheet, was added. This situation
has been rectified.
4. Inconel in Material Database – The database modification
that added structural steel to version 2.2.0 of TRIFLEXâWindows
resulted in Inconel Alloy 625 being inadvertently removed
from the material table. This release replaces Inconel and
its associated properties back into the database as it was
in versions prior to 2.2.0.
5. Aladdin HASP Driver – The Aladdin HASP Device
Driver used to communicate with the Security Activator has
been updated to version 4.81. This allows more efficient
data exchange between program and activator and facilitates
use of either a USB or parallel port activator.
6. Buried Elbows – Under some circumstances, an extraneous
node was automatically assigned to a bend when soil interaction
was specified. This would lead to a mismatch between the
number of calculated data points and the number of data
points being reported and, ultimately, to a program malfunction.
This error has been corrected.
7. Nonlinear Restraints and British Codes – A program
error was detected when using nonlinear restraints with
the British Codes (BS7159 and UKOOA) wherein an erroneous
result could be given in the spring hanger report depending
on the number and placement of spring hangers. This release
has fixed this difficulty.
8. Branch Connection Flexibility Factor – This release
of TRIFLEXâWindows addresses a problem in the calculation
of Branch element flexibility factors using ASME NB 3686.5
when specifying that the stress intensification factors
should be calculated using ASME methods.
9. Frictional Restraint – Labels for frictional restraints
at data points now appear in the code compliance spreadsheet
rather than being shown as a blank in the Node Location
10. Corrosion Allowance – The corrosion allowance
for components cannot be larger than the specified wall
thickness. An error message is now issued should the User
try to set it to be so. Previously, no error was flagged
and the resultant error in calculation would lead to erroneous
results in the code compliance data.
