  • ASME/ANSI Flanges

    • Code Case 2901
      Code Case 2901 is now available as an alternative method for evaluating external loads on ASME B16.5/16.47 welding neck flanges. This option may be activated on the ASME Codes dialog. The intent of the Code Case 2901 method is to remove the overly conservative results present in the Equivalent Pressure and Equivalent Force methods, while still providing a conservative result (see PVP2013-97814). Note that external loads on bolted flanges joints must be considered to be in compliance with the ASME Code (see ASME Interpretation VIII-1-16-85).

      Code Case 2901 increases the pressure rating from ASME B16.5/B16.47 by a moment factor, Fm, before subtracting the pressure reduction from external loads. The result may not be higher than the pressure rating from ASME B16.5/B16.47. The moment factor is selected from Code Case 2901 and is based on flange size and class.

      A reduced user defined moment factor can be set in the ASME B16.5/16.47 Flange dialog by activating the User Defined Moment Correction Factor option switch. Per Code Case 2901, this is recommended 'if the loading is primarily sustained in nature and the bolted flange joint operates at a temperature where gasket creep/relaxation will be significant (typically above 450°F (232°C) metal temperature).' [64254]

      How to use Code Case 2901

    • Flange class auto-increase to meet design condition
      A new option is now available that automatically increases the ASME B16.5/B16.47 flange class to meet the design condition. This feature selects an appropriate flange class upon initial creation and updates existing flanges that do not meet the design condition. The flange class auto-increase option is active by default for Builds 7810 and onward. Files created prior to Build 7810 will open with the option deactivated. The option can be enabled\disabled in Set Mode Options -> Defaults -> Flanges. [64742]

  • Bolts

    • Improved dialog for creating user defined bolts
      The following improvements to the Edit Bolt Sizes dialog are now available:
      • The dialog is now in a spreadsheet format to facilitate comparison between bolt values.
      • User-defined bolts can now be created for metric ASME B1.13M bolts.
      • Separate tabs are available for Series 8, Coarse, Metric - ISO 724, and Metric - ASME B1.13M bolt types.
      • Bolts may be filtered to display standard or user defined types.
      • All bolt edits and removals are reflected as they are performed, but are only saved once the Ok button is selected.
      • The Errors and Warnings windows are now available to report problems with values entered for user defined bolts as they are created and updated.
      • User defined bolts are highlighted to display their saved state.
      • Individual cells corresponding to specific bolt property values are now highlighted to display warnings and errors caused by those selected values.
      • A legend is provided to report issues with specific value bolt values.
      [64320]

  • Gaskets

    • ASME B16.20 and B16.21 standard dimensions and other gasket improvements
      Gasket improvements include standard dimension look-ups per ASME B16.20 and B16.21, gasket dialog enhancements, and the addition of over 5000 gaskets from Flexitallic, Garlock, Lamons, and Teadit.
      (1) Standard gasket dimension look-ups for ASME B16.5/B16.47 flanges are now performed for gasket types included in ASME B16.20 Metallic Gaskets for Pipe Flanges and ASME B16.21 Nonmetallic Flat Gaskets for Pipe Flanges. Accurate gasket dimensions are necessary in order to determine the gasket reaction diameter when external loads are considered in determining the flange pressure rating.
      • Gasket diameters are automatically loaded and set to read-only when a spiral wound, jacketed, kammprofile, or flat nonmetallic gasket is selected.
      • A default gasket thickness is automatically populated but may be changed.
      • The User Defined Gasket Dimensions option may be used to override the ASME B16.20 and B16.21 dimensions. Changing the dimensions typically indicates an off-the-shelf gasket will not be ordered.
      (2) The gasket selection is now chosen from an enhanced gasket dialog using the Select Gasket option button for standard ASME B16.5/B16.47 flanges, custom flanges, and the default specified on the Flanges page in Set Mode.
      • Over 5000 gaskets are now available from Flexitallic, Garlock, Lamons, and Teadit. User defined gaskets from other manufacturers may still be added.
      • The ASME Table 2-5.1 generic gasket descriptions are provided under the Manufacturer drop-down. These may be used for when a specific manufacturer is not desired.
      • Manufacturer, Type, Style, Material, and Filler/Facing Material filters allow specific gaskets to be easily located.
      • The Clear All Filters button quickly reverts back to display the entire gasket list.
      • The Clear Selection and Close button clears the gasket description from flange dialogs, indicating that no gasket is selected.
      • The Factor m and Factor y inputs are automatically populated based on the gasket selection but may be changed if required based on additional manufacturer gasket information. Changing the m&y values no longer clears the gasket description.
      (3) The ASME B16.5/B16.47 Flange Gasket option is now available in the Global Change dialog. This option provides the ability to change the gasket description, gasket factor m, or gasket factor y for several ASME B16.5/16.47 flanges at once. [64716]

  • Jackets

    • Figure 9-5 sketches (d-1) and (d-2) now available
      Figure 9-5 sketches (d-1) and (d-2) (Division 2 Table 4.11 Detail 4(a) and Detail 4(b)) are now available inside of the Jacket Closure dialog for Type 1 jackets. [63171]

  • Nozzles

    • Option to size nozzle welds based on the nominal head thickness
      The required weld thickness for nozzles located on formed heads may now be sized based on the nominal head thickness or the minimum head thickness after forming. This option can be enabled\disabled in Set Mode Options -> Calculations -> Nozzles. By default, nozzle weld requirements are sized based off the nominal formed head thickness. Previously, the weld requirements were always sized based on the minimum head thickness. [54545]

      How to use formed head nominal thickness instead of the minimum thickness to size welds



Additional Features

  • ASME/ANSI Flanges

    • Nominal size when flange class is changed
      The Nominal Size input in the Select ASME B16.5/16.47 Flange dialog no longer changes to NPS ½ when a flange class is selected that is not available at the selected nominal size. The dialog now issues a warning before reverting the flange class to the previous selection. [64944]

  • Bolts

    • New sizes added for Metric AISC and Metric ISO 724
      M18 x 2.5, M52 x 5, and M60 x 5.5 are now available metric bolt sizes for AISC and ISO 724 root area methods. [57986]

  • Component Tree Pane

    • Cylinder properties now editable
      The length, thickness, and diameter properties of cylinders may now be edited directly in the Cylinder Properties section of the Component Tree. [61770]

  • Custom Flanges

    • Gasket type reported
      The gasket type is now reported for a custom flange with a gasket specified. [65004]

  • Flanges

    • Global change of ASME B16.5/16.47 flange materials
      Using global change to change the nominal size of ASME B16.5/16.47 flanges now sets the flange material to the material scheme setting if the flange is going from B16.5 to B16.47 (or vice versa) and is constructed of a material that is not compatible with B16.47 (or B16.5 in the alternate scenario). Additionally, if a global material change is performed on a combination of B16.5 and B16.47 flanges, and the selected new material is not compatible with B16.47, the B16.47 flanges will remain unchanged; similarly, if the new material is not compatible with B16.5 flanges, the B16.5 flanges will remain unchanged. [64533]

  • Forms

    • ASME Revision Update
      The header for forms U1, U1A, U2, and U2A are updated to reflect the latest ASME revision for electronic submissions to the National Board of Boiler and Pressure Vessel Inspectors. [64754]

    • NBIC Form R-1
      The National Board Inspection Code form R-1 updated to Revision 15. [65009]

    • Nominal thickness now automatically increased to meet the design thickness
      The intermediate skirt nominal thickness now automatically increases to the next available plate size when in design mode. [64363]

  • Jackets

    • Closure to shell welds
      The vessel outer corrosion in the jacketed region is now considered in the closure to shell weld calculations when larger than the jacket inner corrosion. Additionally, the vessel outer corrosion is now considered in the closure to shell weld calculations when larger than the jacket outer corrosion. [64525]

  • Legs

    • Shear load on braced legs calculation update
      The calculation of the shear load on each leg (Vn) for braced legs now uses the most recent equation from Procedure 4-5: Seismic Design - Vessel on Braced Legs in Pressure Vessel Design Manual: Fourth Edition by Dennis Moss. Previously, Vn for each leg was calculated using the previous edition of this book. [63777]

  • Material Scheme

    • ASME B16.5/16.47 flanges created with nozzle quick design
      ASME B16.5 and B16.47 flanges created using the Nozzle -> Quick Design menu option now follow the material scheme settings. [64532]

    • Separate material entries for ASME B16.5 and B16.47 flanges
      Separate material entries are now present in the material scheme for ASME B16.5 and B16.47 flanges. Previously, there were some cases where a selection would be valid in one standard but not the other. Invalid selections follow the existing behavior of reporting a blank value and highlighting the cell red. [64452]

  • Nozzle Schedule

    • ASME B16.47 Series A and B flanges
      ASME B16.47 weld neck flanges now indicate Series A or B in the Nozzle Schedule report. [65014]

    • Nozzles machined from bar stock
      A "Machined from Bar Stock" option switch is now available in the Nozzle dialog for nozzles manufactured from bar stock material. Nozzles with this option switch enabled are now considered seamless in the Radiography Summary. [58095]

  • Radiography

    • Weld seam is made without filler option available for user defined joint efficiencies
      The Weld seam is made without filler option switch is now available for user defined longitudinal weld seam radiographies for materials with welded and seamless pipe product forms. Previously, this option was only available for welded pipe and Full UW-11(a) Type 1 longitudinal weld seam radiography. [58148]

  • Revisions History

    • Default operator name
      A Save as Default button is now available for the operator name in the Revision History dialog. [64070]

  • Shipping Saddles

    • Pressure during shipment
      Pressure during shipment is no longer limited to 15 psi. A warning is now issued if shipment pressure is specified above 15 psi. [63490]

  • Skirt Base Ring

    • Skirt allowable stress for gusset reaction check
      The gusset reaction check from the Jawad and Farr GUIDEBOOK 1998 (Eq. 12.14) now reports the required allowable stress when the skirt is over-stressed. Previously, the allowable stress was only reported when the gusset reaction check passed. [61520]

  • Support Skirts

    • Automatic skirt thickness increase
      Skirt thickness is now automatically increased when required for design loadings. [8602]

  • Vessel Wizard

    • Number of bolts per leg input
      The number of bolts per leg input is now available in the Legs page of the Supports dialog in the Vessel Wizard. [64603]

  • WRC 537

    • Nozzle loads dialog improvements
      The following improvements were made to the Standard Nozzle Loads dialog:
      • Data set changes are now auto saved when pressing ok in the dialog and switching between units. Previously, data sets were only saved when the Save New Data Set button was selected.
      • Existing nozzle loads are no longer cut off when the columns widths are adjusted in the WRC 537 Load Cases for Nozzle -> Standard Nozzle Loads dialog.
      • New nozzle load data sets must now have a unique name. Previously, a new data set could be named the same as an existing one and would replace the existing data set when saved.
      • New data sets can no longer be named with brackets. Previously, new data sets with "[Metric]" at the end of the name would be corrupted on creation and would appear with API 660 loads.
      [64055]

  • Wind Loads

    • Effective width for ASCE / IBC wind load calculation
      The ASCE / IBC wind calculations now use a weighted average formula (from Article 4.1.7.2 of NBC Canada) to determine the effective width, b, of the vessel. Previously, the minimum vessel diameter was used. [59789]

  • XML

    • Nozzles attached to elbow pipes
      Nozzles and associated flanges attached to elbow pipes are now reported in the XML export. [64193]

Heat Exchanger



Highlighted Features

  • Heat Exchanger

    • Tube bundle replacement
      An option to design a standalone tube bundle is now available. To enable it, activate the Tube Bundle Replacement checkbox in the Exchanger Options page of the Heat Exchanger dialog. Inputs that are not applicable are hidden or disabled in the Heat Exchanger wizard and dialog. When a shell or channel is connected to the front tubesheet with a gasketed joint, that chamber's components are removed from consideration (floating tubesheet covers are excluded from this rule). The reports only include components that are part of the standalone tube bundle with the exception of flanges in the tubesheet assembly, for which detailed reports are included to document the bolt loads used in the tubesheet analysis. [57247]



Additional Features

  • Long Seams

    • Floating heads
      The long seams of heat exchanger floating heads are now displayed in the Long Seams dialog and are reported in the Long Seam Summary. [64701]

  • Nozzles

    • Nozzle flange gasket default changed to Set Mode Options default
      Nozzle flange gaskets now use the setting from Set Mode Options -> Flanges -> Gasket Defaults. Previously, the nozzle flange gasket setting was loaded from the heat exchanger defaults file. [64967]

  • Pass Partition

    • Copy 'm' and 'y' from front channel flange gasket button
      The "Copy 'm' and 'y' from front channel flange gasket" button in the Pass Partition tab of the Heat Exchanger dialog now copies from B16.5/16.47 flanges. Previously, the copy button only applied to Appendix 2 flanges . [64966]

  • Tubesheets

    • Material properties reported
      Application of normalization, fine grain practice, impact testing, and post weld heat treatment are now reported in the input echo section of the ASME Tubesheet report. [57951]

  • U-Tube HX

    • Test liquid weight
      The test liquid weight in the shell closure of U-tube exchangers is now more accurate when a tube layout is active. Previously, the approximation used when a tube layout is not present was used in all cases. [64121]

Division 2 2007 Edition and Later

  • Material

    • Division 2 time dependent provisions incorrectly applied to Class 1 vessels
      The time dependent (creep range) provisions in Division 2 are no longer applied to Division 2 Class 1 vessels. Previously, all Division 2 Class 1 vessels were calculated as if in the creep range due to a logic error.

      Time dependent provisions in Division 2 include the following:
      • Formed heads internal pressure - strength factor C3 used in calculation of Py (equation 4.3.17)
      • Nozzles in cylinders and cones - non-linearity factor (lambda) applied to area in the shell A1 (equations 4.5.23 and 4.5.24)
      • Cone juncture - allowable primary plus secondary stress evaluated using 4.1.6.3
      [64485]

  • Material Scheme

    • B16.9 pipe caps
      The B16.9 pipe cap material for the Carbon Steel scheme is now set to SA-234 WPB in the Division 2 Class 1 columns. [64831]
