• Governing test stress
  The governing test stress is now reported in the Hydrostatic Test report. Previously, the primary general membrane stress plus primary bending stress (P_m + P_b) was always reported unless the primary general membrane stress (P_m) exceeded the allowable stress. [55193]
  
  

Cylinders

• Allowable axial compressive stress
  The allowable axial compressive stress is determined from the minimum of the allowable tensile stress and the allowable axial compressive stress calculated from Jawad and Farr GUIDEBOOK 1998 (Eq. 2.25) if the internal design temperature exceeds the vacuum chart temperature limit. A new calculation option switch Limit allowable compressive stress to vacuum chart limit in the Set Mode > General 2 > Calculation Options page now gives the ability to limit the allowable stress to the vacuum chart stress value at the highest temperature available. This prevents a higher allowable axial compressive stress from being used when the design temperature exceeds the vacuum chart maximum temperature. [53955]

  The Figure UCS-66.1 (Division 2 paragraph 3.11.2.5) MDMT reduction is now permitted for materials that are impact tested per the ASME Section II Part A material specification. The rated MDMT is taken as the smaller of the material specification impact test temperature minus the UCS-66(g) (Division 2 paragraph 3.11.2.4.b) reduction or the material specification impact test temperature minus the UCS-66.1 MDMT reduction, but not lower than -155°F (-104°C ). [7434]
  
  
• Non-ferrous and high alloy material impact test temperature now considered
  The rated MDMT for nonferrous and high alloy steel materials is now taken as the colder of the impact test temperature or the Code impact test exemption temperature. Previously, these materials were always rated to the Code exemption temperature even when impact tested to a colder temperature. [54764]

Tubesheets

• TEMA tube hole diameters
  Tube hole diameters may now be specified as Standard Fit or Special Close Fit per TEMA RCB-7.41 in the Seventh and Eighth Edition and TEMA RCB-7.21 in the Ninth Edition. A Custom Fit, which does not conform to the TEMA Standard Fit or Special Close Fit, may also be specified. This option is available on the Tube Related Inputs section of the Tubesheets page in the Heat Exchanger Dialog. The tube hole diameter specified is modeled in the solid model. [54956]
  
  

XML

• XML and XML3D formats extended
  The XML and XML3D formats now include the following:
  • Baffle tube hole diameter
  • Identifier and idNumber for pass partitions
  • The < idNumber > and < identifier > tags for the tube bundle
  • Tubesheet bolting information (size and location)
  [55622]
  
  

Support Skirts

• Insulation details in skirt report
  Insulation and insulation support details are now reported in the echo section of the skirt report. [52877]
  
  

Appendix 14

• Integral flat head with large single circular central opening
  Appendix 14 (Division 2 Part 4.6.4) integral flat heads with a large, single, circular, centrally located opening design is now available. When a central opening in a flat head exceeds one-half of the head diameter, use the Component -> Appendix 14 Flat Head menu option to add the head and central opening. Appendix 14 heads must be located on a cylinder or nozzle in order to complete the calculations.
  
  Highlights of the new design feature include:
  • Figure UG-34 sketches (a), (b-1), (b-2), (d), (g), (h), and (i) weld configurations are available.
  • When Figure UG-34 sketch (h) or (i) are selected, Figure UW-13.2 corner joint corner joint sketches (a) through (f) are available.
  • To design a flat integral head without an attached nozzle, deactivate the Head includes centrally located nozzle option switch.
  • The design rules for an opening without an attached nozzle or hub are used when the central nozzle is attached with partial penetration welds .
  • To attach or edit an ASME B16.5/B16.47 flange or Appendix 2 flange to the end of the large central nozzle, select the Nozzle Connection option.
  • Rim openings may be added after the integral flat is created using the Nozzle menu option. Rim opening spacing checks per UG-39(b)(2) and (b)(3) are automatically performed.
  • As an alternative to the area replacement rules for rim openings, the flat integral head thickness may be increased to provide reinforcement by activating the option switch Increase t for reinforcement per UG-39(c)(2). For multiple rim openings when the spacing between adjacent openings is less than twice but equal to or greater than 1.25 the average diameter of the pair, the ligament rules of UG-39(e)(2) are used.

Ellipsoidal Heads

• Code Case 2804
  The Table 6.1 forming strain equation for formed heads now reports D_f instead of D_o for the final outside diameter of the component after forming. This correction was issued as Errata and published in Code Case 2804. [55364]
  
  

MDMT

• Carbon and low alloy steels
  The lowest possible minimum design metal temperature (MDMT) without impact testing is now -104°C for custom flanges and bolted covers in metric units. This limit is also used when adjusting the MDMT using the stress ratio for impact tested materials. Previously, this limit was incorrectly taken as -105°C (the Division 1 limit). [55172]
  
  
• Design MDMT input now available for user defined non-ferrous materials
  The design MDMT input is now available in the component dialog for components constructed of user defined non-ferrous materials. Previously, the design MDMT input was only available for ferrous user defined materials and all ASME Section II Part D materials. [55305]
