3-D piping models made in Plant Design Systems exist. The piping
department prints isometric drawings on paper
Isometric drawings are passed to mechanical department for Piping
Stress Analysis in TRIFLEX Static
Isometric drawings are also used for Transient Fluid Flow Analysis in
PIPENET Transient
Results from PIPENET Transient are passed on paper for Piping Stress
Analysis in TRIFLEX Dynamic
The results of Piping Stress Analysis must be drawn manually in
AutoCAD or MicroStation as Stress Isometrics
Results from PIPENET and TRIFLEX are passed on paper to Piping
Department for updating the 3-D CAD models
All data transfer is done on paper or via non-intelligent CAD drawings

The drawbacks of the traditional
information transfer

The data entry is made many times:



Very expensive “man-hour” approach. Engineers
use most of time to enter data before they can
focus on solving the engineering problem
Data inconsistency and mistakes cannot be
avoided
Significant expenses are involved with crosschecking of the data between disciplines

Benefits of Life Cycle Solution




Single data entry. Data are used throughout
disciplines and exchanged as digital files
Data consistent between all systems
Limited need for data cross-checking
Saved time and money

The administrator “I-CONVERT”s all 3-D CAD Specs into I-SKETCH
format *one time*
The engineer imports needed CAD Iso files into I-SKETCH. A piping
system can be build out of isometric drawings
Smart Stress Iso transfers piping system models to TRIFLEX
Piping Stress Analysis is done in TRIFLEX. The engineer takes
decisions about supports’ locations and functions and modifies the
piping geometry as needed to meet Code Compliance
The engineer introduces the necessary changes to the model in ISKETCH
Smart Stress Iso creates Stress Isometrics based on I-SKETCH
geometry and TRIFLEX data to document modifications
The final piping system can be “I-EXPORT”ed from I-SKETCH to 3-D
CAD system as new modified 3-D CAD model

Smart Stress Iso Benefits






Data are entered once, only when necessary
Piping Specs made once are further re-used
All data transfer is done by digital files. Data
consistency is ensured
The need for consistency checking is greatly reduced
I-SKETCH is an inexpensive and very easy tool for
modification work. You do not need to be CAD
operator to work with I-SKETCH
The work time is used efficiently to solve problems
not to enter data into TRIFLEX

PIPENET Transient to
TRIFLEX Dynamic (PTR2TRD)




TRIFLEX Dynamic allows Time History Analysis (THA)
The required data for TRIFLEX THA are Time
Functions and Nodal Excitations. It is very difficult to
guess these data
PIPENET Transient calculates forces in a piping
system based on transient fluid flow calculations
PTR2TRD application will transfer the PIPENET
Transient force information to TRIFLEX Dynamic as
Time Functions and Nodal Excitations

Create and solve simulation problem in PIPENET
Transient. Ask the program to generate Force File
Create a piping network in TRIFLEX and solve it in
Static with Mode Shapes and Frequencies
Convert the PIPENET Force File to TRIFLEX Time
Function (TTC) and Nodal Excitation (THA) files
Open TTC and THA files in TRIFLEX
Run Time History Analysis in TRIFLEX

PTR2TRD Benefits





Transient Fluid Flow analysis is the reliable tool to
provide excitation information for Piping Stress Time
History Analysis
Thousands of data points are transferred in seconds
The data consistency is ensured
PTR2TRD automatically transforms the coordinate
systems and converts engineering units
Time and money are saved
