The information workflowin modification engineering 3-D CAD Plant Design System Piping Stress Analysis(TRIFLEX) Fluid Flow Analysis(PIPENET)
The information transfer today • 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 cross-checking 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

Smart Stress Iso Workflow • 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 I-SKETCH • 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 toTRIFLEX 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

PTR2TRD Workflow • 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
