    • Deactivation of detailed test stress calculations for exchanger components
      Detailed hydrotest calculations for heat exchanger components may now be deactivated by turning off the Calculate hydrotest stress option on the Set Mode Options > Defaults > Testing page. Detailed test stress calculations per UHX are not mandatory per ASME Interpretation VIII-1-10-12. [52268]

  • Tubesheets

    • ASME Section VIII, Division 1 2015 Edition
      The 2015 Edition of the ASME Code is now available. The additions and changes follow:

      (1) The materials database now includes all ASME Section II, Part D 2015 Edition data for both Customary and Metric editions. This includes all materials from Tables 1A, 1B and 3. In addition, Table U (tensile strength), Table Y-1 (yield strength), Tables TE-1 through TE-5 (thermal expansion coefficients), Tables TM-1 through TM-5 (elastic moduli) and all vacuum charts have been updated.

      (2) Table UHX-8.1 Tubesheet Effective Bolt Load, W*: Table UHX-8.1 updated to reflect the design and operating load case changes made in the 2013 Edition of the Code. The effective bolt load for design load case 4 is now taken as zero.

      (3) Tables UHX-13.4-2, UHX-13.8.4-1, UHX-14.6.4-1 modified.

      (5) Table UHX-17 updated to reflect the design and operating load case changes made in the 2013 Edition of the Code. Flanged and flued expansion joint finite element analysis per TEMA 9th Edition now includes these changes.

      (6) Appendix 26 Bellows Expansion Joints
      • Table 26-2-1 Maximum Design Temperatures for Application of the Rules of Mandatory Appendix 26 replaces the previous single maximum temperature limit of 800°F (425°C). [57112]

      • Operating pressures now considered in maximum pressure determination
        The maximum pressure determination now considers operating pressures by implementing a ratio between the design and operating pressures. Previously, only one pressure on each side of the exchanger was used in the maximum pressure iteration, which could result in a MAWP lower than the input design pressure. [56725]



    Additional Features

    • Expansion Joints

      • Material properties at operating temperature per ASME Section VIII Division 1 Appendix 5-1
        Flanged and flued expansion joints designed per TEMA 9th Edition now use the material properties at the operating temperature for load cases that include thermal loading per ASME Section VIII Division 1 Appendix 5-1. Previously, the material properties at the design temperature were always used. [57124]

      • Warning when running TEMA 9th Edition FEA calculations while multiple instances of COMPRESS are open
        A new warning stating "It appears that more than one instance of COMPRESS is running. Running TEMA 9th FEA calculations in more than one instance of COMPRESS simultaneously causes known errors." is provided when TEMA 9th Edition FEA calculations are run while multiple instances of COMPRESS are running. The option to continue running the calculations is provided. It is safe to run the calculations while multiple instances of COMPRESS are open as long as only one TEMA 9th FEA calculation is being performed at any given time. Running two TEMA 9th FEA calculations simultaneously may result in incorrect results or failure of the calculations. [57449]

    • Heat Exchanger

      • UHX-10(d) deficiency for integral channel reducers
        A deficiency is now reported when a reducer channel is integral to the tubesheet and the exchanger is analyzed per the ASME UHX rules. Per UHX-10(d), the channel component integral with the tubesheet shall be either a cylinder or hemispherical head. [57466]

    • Heat Exchanger Dialog

      • Hydrotest condition option for design conditions 2 and 3
        The option This is a Hydrotest Design Condition is no longer active by default for design conditions 2 and 3 when creating a new heat exchanger using the standard HeatExchangerDefaults.CWHX file. [56923]

    • Tubesheets

      • Operating pressure of zero
        The analysis now automatically sets the operating pressure equal to the design pressure if the operating pressure is entered as zero. [57235]

      • Tube to tubesheet joint loads removed for external pressure conditions
        External pressure conditions are no longer considered in the tube to tubesheet joint load investigation inside of the ASME tubesheet report when in design mode. [57380]

    • XML

      • ASME B16.5/B16.47 body flange gasket m and y factors
        Gasket factors m and y for ASME B16.5/B16.47 body flanges are now included in the XML output. [57182]

      (8) 4.5.2.2 Dimensions and Shape of Nozzles: A new deficiency is issued when the limits of reinforcement of a nozzle fall onto the flat portion of a flat head. Previously, a warning was issued when the limits of reinforcement of a nozzle fell onto the flat portion of a flat head.

      (9) Table 6.1 Forming Strain: In the equation for all one-piece, double-curved circumferential products formed by any process that includes dishing or cold spinning, Do has been replaced by Df, and the definition for Df has been revised to include “of component after forming.”

Additional Features

  • Extreme Fiber Elongation

    • Forming strain for one-piece, double-curved heads now calculated
      A Perform fiber elongation calculation per 6.1.2.3(d) switch that provides an input for the blank plate diameter (Db) is now available in the Ellipsoidal Head Dimensions and F&D Head Dimensions dialogs when Longitudinal Seam NDE is set to Seamless No NDE. The fiber elongation is calculated when the switch is active. Previously, fiber elongation calculations were not performed for seamless, double-curved heads because no input was available for the blank plate diameter. Straight flanges associated with seamless heads no longer report fiber elongation calculations. Fiber elongation for seamless hemispherical heads is now calculated using the Table 6.1 equation for heads assembled from formed segments. Previously, fiber elongation calculations were not performed for seamless hemispherical heads. [57170]
