COMPRESS


  • Nozzles

    • Nozzle longitudinal and circumferential seam radiography settings
      The longitudinal and circumferential seam radiography may now be specified in the Nozzle Radiography Settings dialog by selecting the Radiography Settings button on the first page of the Nozzle dialog. Previously, a joint efficiency input located in the Nozzle Calculation Options dialog was used to simulate a radiography specification for the Radiography Summary and was used in the applicable nozzle calculations. [56510]

  • Saddles

    • New condition now investigated for vessels with corrosion
      Saddle calculations now investigate the new condition when corrosion is applied to the vessel. The echo section has been updated to include the operating, new design pressure and weight, and load cases in the new condition have been added to the component report. In addition, calculations such as the shear stress in anchor bolting, web plate buckling check, primary bending, secondary bending, and the saddle base plate thickness check all account for loading in the new condition which may govern over the corroded load case. [59208]

  • ASME PCC-1

    • Appendix O permissible bolt stress default values
      The default values of Sbmax and Sbmin are now 70% of bolt yield stress and 40% of bolt yield stress, respectively, in the ASME PCC-1 Appendix O Variables dialog. These values are suggested per API 660 and can be manually changed. [70441]

    • Calculations enabled for flanges on nozzle piping
      ASME PCC-1 Appendix O calculations are now available for flanges on nozzle piping using Select ASME B16.5/16.47 Flange -> ASME PCC-1 Appendix O Bolt Stress Determination. [68940]

  • ASME/ANSI Flanges

    • Flange face moment calculation
      The resultant moment at the flange face calculation for WRC nozzle loads now considers negative loads as the opposite direction as positive loads. Previously, the load direction was not considered, and the moment was always reduced by the moment induced from shear force. [70835]

  • Appendix 2 Flanges

    • High stress material equivalent used for hub calculations on low stress materials
      Flanges designed with low stress materials now use the high stress equivalent properties of the selected material for hub related calculations. [6665]

  • Custom Flanges

    • Circumferential seam input for standalone weld neck integral and reverse integral flanges
      The Circumferential Seam RT input is now available for standalone weld neck integral and reverse integral flange types. Previously, the input was read-only and Full UW-11(a) Type 1 was selected by default. [54330]

  • FEA-Nozzles

    • Plot graphics improved for nozzles on longer vessels
      The FEA plot graphics in Codeware NozzlePRO 15.0 are now correctly scaled in the output of the analysis when Run FE is selected and the vessel length is very large compared to its diameter. Previously, the plots produced were too small to be visible. [70723]

  • Nozzles

    • "Moments on nozzle too small for moment on flange" deficiency now considered a warning
      The message "Moments on nozzle too small for moment on flange" issued when a ASME B16.5/16.47 flange or custom flange with user-defined loading active does not match WRC loads for the corresponding nozzle, is now a warning instead of a deficiency. [70732]

    • Editing nozzle and flange with an attached bolted cover nozzle
      The parent nozzle and flange for a nozzle, flange, bolted cover, bolted cover nozzle combination, may now be edited directly. Previously, only the parent bolted cover could be edited directly and the bolted cover nozzle would need to be deleted to edit the parent nozzle and flange. [1609]

    • Plan view display visibility
      The lines displayed in the Plan View dialog can now be altered to increase the line thickness using the Line Weight dropdown to enhance visibility. [70860]

  • Out-of-Roundness

    • Exclude identical segments
      Out of roundness calculations for cylindrical components with multiple segments of identical geometries no longer report identical results. [70550]

  • Platform/Ladders

    • Ladder cage now optional
      Cages may now be removed from ladders with the Allow cage on ladder option switch located in the Add a Platform & Ladder dialog. The default option switch setting may be changed in Set Mode Options -> Platform and Ladder. The status of the switch is reflected in the Platform/Ladder component report. [65080]

  • Specification Sheet Data Pane

    • Design MDMT set in the Design Requirements pane for a blank file
      The design MDMT can now be set in the Design Requirements pane for a blank file. Previously, this value would revert to the default value set in Set Mode Options -> Defaults -> General after altering the value. [70249]

  • Wind Loads

    • ASCE 7 and IBC basic wind speed metric units
      The Basic Wind Speed input in the Wind Code dialog now uses m/s instead of km/h when S.I. or M.K.S. units are specified in order to make entry from the ASCE 7 maps more convenient. Additionally, the vortex shedding wind speed calculations now report in m/s. [63607]

  • Wind and Seismic

    • Option to set the wind code selection to None
      The wind code selection can now be set to None within the Wind Code dialog. This option removes any previous wind code calculations or presence in the Delete Component dialog. [58527]

    • U-Tube HX

    • RCB-2.31 U-bend requirements
      The Tube Minimum Thickness in the Tubes report is now reduced by the tube bend thinning factor for U-tube heat exchangers. The Mean Bend Radius, min is now an available input on the Tubes and Shell page of the Heat Exchanger dialog in order to calculate the thinning factor. The MAP, MAWP, and MAEP calculations are updated to include the new tube minimum thickness. An API 660 warning appears if the minimum mean tube bend radius is less than twice the tube outer diameter. [60998]

    • PCC-1

      • Appendix O tubesheet assembly warning
        A warning is now issued when the ASME PCC-1 Appendix O Bolt Stress Determination option switch is active in the Flange Type dialog for one flange in a tubesheet assembly and not active for the mating flange, except in cases when the option switch is not available for the mating flange. [71035]

    • TEMA Backing Rings

      • Switching from rating to design mode updates thickness when less than required thickness
        The TEMA Backing Ring Flange Thickness, T for Style A and C backing rings and TEMA Backing Ring Flange Thickness for Style B and D backing rings is now correctly updated to the minimum required thickness when switching from rating to design mode when the thickness is less than the required thickness. [69835]

    • Tube Layout

      • Edit heat exchanger nozzle roles
        The Nozzles page of the Heat Exchanger dialog now contains the option Edit Nozzle Roles after the heat exchanger has been created. The Nozzle Role Editor dialog allows available nozzles to be assigned to the Inlet, Outlet, Vent, Drain, and Auxiliary Connections for the shell side and tube side. Changes to the Nozzle Role Editor update the heat exchanger Nozzles page, Tube Layout page, the Nozzle dialogs and reports, and the XML. Additionally, adding nozzles to an heat exchanger file created without nozzles now generates a blank Nozzles page in the Heat Exchanger dialog so that nozzle roles can be assigned. [58193]

    • U-Tube HX

      • Tube bend forming strain
        Tubes report now includes the forming strain of tube bends per Table UG-79-1 and Table 6.1. [60999]
