4.46 R262150 14.05.2005

  • Adjusted stress analysis methods for tees and branches in district heating networks. Safety margins for static stress and fatigue failure analyses were reduced, which allows the use of thinner branches and tees

  • Added Start-Pro (in addition to Start-Lite), where restrictions on the number of elements are removed. This is especially applicable for large buried heating networks

  • Implemented analysis of buried transmission pipelines and heating networks with large radius branches and bends

  • Added ability to wedge or not wedge variable spring supports in test state (previously, they were wedged automatically)

  • Nodes with deformation and additional loads are now marked in 3D view. Made changes to the materials database, which allow adjusting the analysis using appropriate standards

  • Unified Start-Elements and Start-Express interfaces

  • Reformatted and corrected materials database

  • Implemented new weight analysis in operating mode

  • Adjusted PUR-insulation stress analysis

4.45, 28.05.2004

  • Added insulation to databases. Database includes weights for common insulation types for pipelines with a diameter of 50 to 1000mm. To set insulation weight for pipe length, simply press "..." and select insulation type. Previously, insulation weight was input manually. The database is open and can be edited

  • Adjusted interaction with soil for buried pipelines

  • Trench width is no longer input

  • Stress from soil weight was reduced due to reduction of safety margins

  • Added insulation stress analysis for buried pipelines with PUR-insulation, where stress is soil pressure

  • A network version of START-PROF can now be installed

  • Added Start-PDMS, for importing data from PDMS to START-PROF

  • Added casing thickness and removed trench width in Start-Open format

4.42, 11.09.2003

4.40, 10.12.2002

  • Adjusted analyses in Start-Base and Start-Elemen ts

  • To bending stress analysis for tees and branches

  • To analysis of interaction with soil for pipes with industrial  polyurethane insulation

  • Added non-parallel shoulders for analyses of buried U and Z-shaped elements

  • Added Start-Nozzle to Start-Elements, which allows flexibility analysis of piping stub-ins into various vessels and equipment. Analyzed using WRC-297 and BS-5500

  • Improved 3D view, added dynamic rotation, move and zoom

  • Added Start-Word, which allows export from START-PROF to Microsoft Word

4.38, 01.07.2002

  • Change analysis methods for buried pipelines with Single Use Compensators

  • Changed database structure (input and editing can now be done in ACCESS)

  • Fixed other minor bugs

4.37, 21.05.2002

  • Took into account the increasing flexibility of non-uniform strength tees

  • Implemented Start-PCF, allowing the import of ISOGEN 3D piping models into START-PROF (including PLANT4D and PlantSpace Design Series)

  • Included new installation packet

4.35, 14.02.2002

  • Automatic stress analysis for buried heat networks with single use compensators. Added changes to interface

01.04.2000
