  • ASME/ANSI Flanges

    • Code Case 2901-1
      The Use Code Case 2901-1 option switch is now available in the ASME Codes dialog. This switch activates the new revision to Code Case 2901, which includes an updated table of moment factors for use in the evaluation of external loads on welding neck flanges. The Use UG-44(b) option switch (Use 4.16.12 in Division 2) in the ASME Codes dialog is still available as an alternative for ASME code editions 2019 and later. [76973]

Heat Exchanger


  • Hydrotest

    • Check added for internal floating components under shell side test pressure
      A new check for internal floating components, such as channels, channel heads and associated straight flanges, flanges and associated hubs, and tubesheet hubs, under shell side test pressure is now available in the Hydrostatic Test report in the Common Components External Pressure Summary Report for Shell side chamber table. This check compares the components’ MAEP cold and new to the shell side test pressure. [69034]

    • Check added for tubes under shell side test pressure
      A new check for tubes under shell side test pressure is now available in the Hydrostatic Test report in the Common Components External Pressure Summary Report for Shell side chamber table. This check compares the tubes MAEP cold and new to the shell side test pressure. [59087]

    • Tube MAEP cold and new is now calculated
      The tubes MAEP cold and new value is now calculated and reported in the Results Summary of the Tubes report for heat exchangers designed using Division 1 rules. The tubes MAEP cold and new value is also now reported in the Pressure Summary as the Tubes Shell Side MAP as well as the Hydrostatic Test report for shell side pressure checks. [75304]

  • Tubesheets

    • Tubesheet hubs added to shell side Hydrostatic Test and Pressure Summary tables
      Internal tubesheet hubs, in floating heat exchangers, have been added to the Component Summary for Shell Side Chamber table in the Pressure Summary and the shell side shop and field hydrostatic test tables in the Hydrostatic Test report. [78532]
