New Features

• DesignCalcs now has two multi-factor authentication and geofencing options to further protect users data and software usage. Users will have to create an account with our team and verify their data before they will be able to use this release. For more information:

• DesignCalcs now supports the additions, deletions and alterations to You can now add, delete, or edit the material properties from SC II, D 2023 for the allowable stress, yield, ultimate stress, modulus of elasticity, mean coefficient of thermal expansion, Poisson’s ratio, and density fields. Changes Additionally, changes to the material tables (e.g. UCS-23, UHA-23, UNF-23.1, etcand so on) in Section VIII-1 2023 have been updated . Updates for MDMT as well as the Minimum Design Metal Temperature (MDMT) curve assignment per UCS-66 in Section VIII-1 2023 have been made. DC-10314, DC-10348, DC-10484, DC-10611

• DesignCalcs has updated the The following updates have been made to reflect the 2023 ASME code edition updates:

  • The three tubesheet types within the software have been updated to support the 2023 code edition changes

  . This includes the following.

  • , including:

    • UHX references have been updated to 4.18.

    • The new coefficients

  :

  • • CC, Cmdelta, Cmtheta, Cqdelta, Cqtheta, and Zeta C have been added.

    • The shell shape coefficients Lambda S and delta S have been updated to be based on mean diameter instead of inside diameter.

    • The channel shape coefficients Lambda C

  ,

  • • and delta C have been updated to be based on mean diameter instead of inside diameter and also to incorporate the new coefficients listed above.

    • The channel coefficient Omega C has been updated to incorporate the new coefficients listed above.

    • The channel membrane and channel bending stresses have been updated based on the new formulations.

    • The calculation for mu* has been moved from step 3 to step 1

  . For

  • • ; for Utube Tubesheets, the calculation for MTS has been moved from step 2 to step 6

  . For

  • • ; for Fixed and Floating Tubesheets, the shown tubesheet bending stress (tau) equation, when Ap and Cp are provided, has been updated to the new simplified form (this has no effect on the result). DC-10698, DC-10769, DC-10780, DC-10791

• The Flexible Shell Element (Thick Walled Expansion Joint) calculations have been updated to reflect changes clarified in the 2023 code. Since this was a clarification, all code years for Thick Walled Expansion Joints will be affected. The 2023 code clarified that edition code. The updated code states the straight flange length is 1/2 half of the length between the outer knuckle tangents for the outer straight and 1/2 half of the the length between the inner knuckle tangents (if they exist) for the inner straight. This will decrease decreases the likelihood that UG-27 calculations will be required. Since this was a clarification, all code years for Thick Walled Expansion Joints will be affected. DC-10671

• Tube-to-Tubesheet weld references have been updated to reflect changes in the 2023 ASME edition code. The former UW-20 strength based calculations have now been moved to UW-20.3. The ; the former non-mandatory Appendix A calculations have been moved to mandatory UW-20.4. These references have been updated. Former ; former Figure A details have been updated to Figure UW-20.2. The user interface simply shows software now displays the 2023 edition options even for older years; , but the report will change now updates based on the year of selection (e.g. a 2019 vessel will show Appendix A in the report while a 2023 vessel will show UW-20.4; , but both will show UW-20.4 in the user interfacesoftware). DC-10622

• DesignCalcs now has The Unthreaded Area as an input in is now displayed on the Custom (Appendix 2) flange form for the bolting information . This was done to better support a clarification made in the 2023 edition of Section VIII, Division 1 in Mandatory Appendix 2. Old designs will set the Unthreaded Area value to the Root Area value. The bolt browser now supports this as well and all of the Unthreaded Area values are set to the Root Area values. In the mathcalculation, the smaller of the Root Area or the Unthreaded area will be used. Since this is a clarification, it affects all previous code years, not just 2023. DC-10566

• There The following updates have been general improvements made to the JSON export:

  • General improvements have been made to the JSON export including warnings about unsupported components in the export and

  disabling the button

  • when licenses are not available. DC-10371

  • The JSON export now supports internal and external corrosion allowances at the component level and

  not just at

  • the vessel level. DC-10703

  • The JSON export now supports Cones. DC-10528

  • The JSON export now supports Nozzles in Cones. DC-10428

  • The JSON export now supports Skirts and Base Rings. DC-10440

Issues Resolved

• Some corrections were made to the The thick walled expansion joint calculations for the outer and inner straights . There were times that now work as expected. Previously, some of the UG-27 values were showing as failing when they should not have been. DC-10671

• An issue was resolved in the JSON export where all elliptical head were assumed to be 2:1. This assumption is no longer madeThe JSON export has been updated to no longer assume that the elliptical heads are 2:1. DC-10462

• An issue was corrected on the The Lug and Support ring reports for ASCE 7-22 have been updated to correctly display when one of the new two-lettered site classes is specified. When the issue occurredPreviously, the site class label would incorrectly show displayed twice without the site class selection being shown at all. The results were not affected by this. DC-10600

• An issue was resolved in the The lifting lug form for lifting lugs in cylinders . The “Calculate Localized Stresses” is now enabled for all applicable cases. Previously, the Calculate Localized Stresses box was disabled for all cases. It is now properly enabled for the applicable cases. DC-10656

MiscMiscellaneous

• The default Hydrotest selection for support calculations is now Max(Ptcalc, Pd) for all new vessel files. DC-10359

• The default B16.5 and B16.47 selection is 2020 for 2023 code vessels by reference via Table U-3/Table 1.1. DC-10337

• The about screen About window now shows support for the 2023 Edition of the code. DC-10932

• The default code year is now 2023 for new vessels. DC-10932

• DesignCalcs has changed the material launch behavior in order to improve the speed of the program launch. You may see a message at material selection The software now opens the Material Selection faster. A message may display that the material is loading. DC-10805

• The message in the Lug form, suggesting the user check the repad for stresses per WRC-107 now suggest the user check the repad stresses with NozzlePRO. DC-10406

• DesignCalcs The software now has some business logic coming from the CEI Interop DLL, shared by multiple programs. This requires a new license. DC-10550, CRTN-4584
