B16.11 Couplings

• ASME B16.11 and custom coupling improvements
  Highlights of the ASME B16.11 and custom coupling updates include:
  (1) New coupling types:
  • ASME B16.11 Boss fittings
  • Manufacturer's Standard
  • Allows standard fittings that are not ASME B16.11 fittings to follow rules in UW-16(f) and be calculated as a straight seamless pipe
  • Diameter, length, and thickness inputs are open
  • May be attached as set in or set on with Outside Fillet Only or Full Penetration Weld options available
  (2) Custom dimensions may now be specified for all socket-welding and threaded coupling types
  • This may be activated using the Specify Custom Dimensions option switch located below the Standard Size Look-Up button.
  • Allows custom couplings to be considered ASME B16.11 couplings, follow rules in UW-16(f), and be calculated as a straight seamless pipe
  • Socket Depth, J and Bore Diameter, D inputs are now available for socket-welding couplings
  • Coupling type and coupling end connection are reported with the coupling description
  (3) Non-radial orientations are now available for set in and set on attachment types
  (4) Socket-welding coupling updates include:
  • Bore thickness now considered in the limits of reinforcement and area calculations
  • Gives credit for coupling thickness at the bore diameter in nozzle area calculations. Previously, the socket wall thickness was used, which could result in overly conservative calculations
  • Half couplings should benefit for set on and set in attachment types as long as the couplings are not set in past the socket depth, J
  • Full couplings should benefit for the set in attachment type if the couplings are set in past the inner socket depth, J
  • The Bill of Materials now reports the socket depth and bore diameter
  • The bore diameter and socket depth now rendered in the solid model
  (5) Coupling projections and lengths are now refreshed on file load and during calculations to correct for changes in parent component diameter and or thickness. Previously, the length only refreshed when navigating through the Nozzle dialog. [67476]
  
  

Dished Covers

• Dished cover bolt circle beyond flange outer diameter
  The dished cover bolt circle may now be specified outside of the flange outer diameter using the Bolt Circle 'C' beyond Flange OD 'A' option switch located in the Dimensions page of the Dished Cover dialog. This option is available for all currently available dished cover types. [5687]
  
  

Material Scheme

• User defined materials in material schemes
  User-defined materials are now available in material schemes. [64263]
  
  

Saddles

• Slotted bolt holes
  Horizontal vessels on saddle supports require a minimum saddle slotted bolt hole length as provided by Process Industry Practices VEFV1100. The Slot Length, Slotted Bolts, and Bolt Hole Diameter Clearance inputs are now available on the second page of the Saddle Design dialog. The Slotted Bolts dropdown allows slotted bolt holes to be placed on either saddle, and defaults to the saddle supporting less weight. Bolt holes are centered on the base plate width and away from rib plates. Minimum required clearance away from bolt hole is provided by AISC Table J3.4. The saddle report includes the calculation for the minimum slotted hole length and determines if the actual slot length input is satisfactory. Previously, the saddle calculations assumed one saddle had slotted bolt holes but no calculation was performed for the minimum slotted hole length. In addition, the solid model now displays bolt holes and slotted bolt holes for the saddles. [66915]
  
  

B16.11 Couplings

• Weld sizing per UW-16(f)(2)(b)
  Standard fittings now consider the requirements of UW-16(f)(2)(b), when applicable, which allows weld sizing as the lesser of 3/32” (2.5 mm) or 0.7t_min. Previously, the lesser of ½” (6 mm) or 0.7t_min was required. [67042]
  
  

Component Tree Pane

• Skirt openings now available
  Skirt openings are now listed in the Component Tree pane and may be edited or deleted directly from the pane. [67291]
  
  

Forms

• Nozzle location now reported in forms
  Nozzle locations are now reported in the Location column of the Nozzles, Inspection, and Safety Valve Openings table and the Additional Nozzles tables in the U-Forms and A-Forms. [67862]
  
  

MDMT

• Stress ratio calculation for UHA and UHT materials
  The stress ratio calculation used in the determination of the MDMT of a component is now displayed in the Material Toughness table for all UHA and UHT materials. Previously, flat covers and custom flanges did not display the stress ratio calculation when these materials types were selected, regardless of whether the rated MDMT met the design MDMT or not. [63895]
  
  

Nozzles

• Nozzle internal projection deficiency changed to warning
  A deficiency issued when a parent component’s inner corrosion is greater than or equal to the attached nozzle’s internal projection is now issued as a warning instead. [66929]
  
  
• Quick design dimension from datum
  Nozzles added with the Quick Design feature now have an additional dimension for the distance from the datum to facilitate in nozzle placement. [67123]
  
  
• Standard size look-up for custom manufactured variable thickness nozzles
  The Standard Size Look-Up option is now available in the Nozzle dialog for custom manufactured variable thickness nozzles. [66804]
  
  
• Weld sizing check no longer performed in the new condition
  Weld sizing checks are no longer performed in the new condition per UG-16(e) in Division 1 and 4.1.4 in Division 2. Previously, these checks were performed for all conditions which is overly conservative for the new condition. Note that the weld check will still be performed in the new condition if the hydrotest is performed at the calculated test pressure. [67205]
  
  

Postweld Heat Treatment

• Weld preheat under 1.5"
  The following text is now reported in a message box warning as well as in the Deficiencies Summary when the Set Mode Options -> Defaults -> Welding -> No Weld Preheat below 1.5" option is active and governing thickness of a component constructed of a P-number 1 material is between 1.25" and 1.5":
  "PWHT is not required if preheat is applied at a minimum temperature of 200°F (95°C) during welding. If preheat during welding will be performed, deactivate the option switch No weld preheat below 1.5" on the Welding page in Set Mode" [67290]
  
  

Set Mode Options F7

• Coupling defaults in Quick Design mode
  The coupling defaults defined in Set Mode Options -> Defaults -> Nozzles 2 now apply to couplings created in Quick Design mode. [67116]
  
  

Settings Summary

• UG-22 note for additional loadings
  A note is now reported in the Settings Summary stating that UG-22(d)(1), (e), (f)-snow, (g), (h), and (i) loads are not considered and additional calculations must be performed if present. [65672]
  
  

Skirt Base Ring

• Metric bolt description in skirt base ring reports
  Metric bolt descriptions are now fully defined in skirt base ring reports. Previously, only the bolt diameter was listed. [65205]
  
  

Skirt Openings

• Deleting from 3D view
  Skirt openings may now be deleted from the 3D view by selecting the skirt opening and pressing the Delete key. [67292]
  
  

Specification Sheet Data Pane

• Equipment Type section is now available
  The Specification Sheet Data pane now contains an Equipment Type section in the Code Requirements pane to specify whether the file contains a vessel, shell and tube heat exchanger, or an air cooled heat exchanger. Starting a new Division 1 file allows an input for a Vessel or Shell and Tube Heat Exchanger to create the corresponding type of file. Air cooled heat exchangers must still be created from the Air Cooled Heat Exchanger button, but the equipment type will reflect this equipment type upon creation. Files created in previous builds will be updated to reflect the equipment type as well. [66786]
  
  

Support Lugs

• Continuous lugs report length reduced
  The length of continuous support lugs is greatly reduced by removing repeated sections of the report. This is a reporting change only and does not affect any calculations. [67517]
  
  

Wind Loads

• Progress dialog when Limit top deflection to option is active
  The automatic shell thickness increases performed when the calculations are run with the Limit top deflection to option active inside of the Wind Code dialog are an iterative process that may take several minutes, or even hours, to converge to a final solution when the wind deflection is large. A progress dialog is now activated when the Limit top deflection to option is active and the wind deflection is larger than the allowable limit. The dialog gives an estimated time remaining to finish the automatic shell increases and an option to abort the process, allowing the ability to manually increase shell thickness for a faster solution without waiting for the entire process to be completed. [67582]
  
  

XML

• General Information section added
  The information from the General Information section of the Specification Sheet Data pane is now available in the XML. [67430]
  
  
• Material UNS node added
  The UNS Number (when present) is now available in the node of the XML [66591]
  
  
• Saddle location information added
  Location data for saddles is now available in the XML. [66737]
  
  

Dished Covers

• Dished covers specified as channel closures
  Dished covers can now be selected as heat exchanger channel closures on the Channel page of the Heat Exchanger dialog. The following summarizes the accompanying features of this option:
  • Two configurations are available: attached to the channel cylinder or attached directly to the tubesheet.
  • Dished covers attached directly to the front tubesheet are connected to the Specify Flange button on the Tubesheets page so that the Dished Cover dialog opens instead of the Flange dialog.
  • Dished cover bolt load calculations have been amended to include the exchanger pass partition gasket load.
  • Fixed heat exchangers with dished covers as front and rear channel closures attached directly to the tubesheet are synchronized to each other to maintain consistency in the tubesheet calculations. Changes to the dished covers in this configuration can only be done on the Channel page of the Heat Exchanger dialog.
  • TEMA only fixed heat exchangers with differing tubesheet thicknesses and a dished cover attached to the tubesheet at one end and a different configuration at the other end synchronize the opposing tube side flange to the dished cover.
  [50389]
  
  

Heat Exchanger

• Pipe caps specified as channel closures
  Pipe caps can now be selected as heat exchanger channel closures on the Channel page of the Heat Exchanger dialog. Three configurations are available: attached to the channel cylinder without body flanges, attached to the channel cylinder with body flanges, and straight flange acts as channel cylinder. Pipe caps are not available as rear shell closures for floating type (a) heat exchangers. [53071]
  
  

Heat Exchanger Dialog

• TEMA Type Specification Added To General Options Page
  Heat exchanger configurations may now be specified by their TEMA type in the General Options page of the Heat Exchanger Wizard.
  
  The TEMA type may be entered directly into the text box labeled TEMA Type, or may be selected via the three dropdown boxes labeled TEMA Front End Stationary Head Type, TEMA Shell Type, and TEMA Rear End Head Type. The options in these dropdowns correspond to the nomenclature outlined in TEMA figure N-1.2.
  
  Specifying the exchanger configuration using the TEMA Type text box or the individual dropdowns will update the front and rear tubesheet configurations to the corresponding UHX figure, as well as the Exchanger Type radio button selection (Fixed, Floating, U-Tube).
  
  If TEMA nomenclature does not cover the desired tubesheet configuration, or lack of familiarity with TEMA precludes the use of these inputs, the precise UHX tubesheet configuration may be selected using the Exchanger Type radio button along with the UHX Front Tubesheet Configuration, UHX Rear Floating Tubesheet Configuration (for floating tubesheets), and UHX Rear Tuebsheet Configuration dropdowns. [67225]
  
  
• Tubesheet configuration moved to General Options page
  The tubesheet ASME configuration is now set on the General Options page of the Heat Exchanger Wizard and can no longer be set in the Tubesheets page of the Heat Exchanger dialog. This, along with the TEMA configuration input, will allow higher-level decisions about the heat exchanger to be made sooner in the design phase, with finer details being filled in later on in the Heat Exchanger Wizard. [57794]
  
  

Material Scheme

• Material schemes for heat exchangers
  Material schemes can now be used in conjunction with the Heat Exchanger Wizard. Material selections in the Heat Exchanger Wizard will now follow the material selection in its chamber's selected material scheme, as will nozzles and nozzle connections after the heat exchanger design is completed.
  
  The material schemes for the tube and shell side chambers can be set in the Design Requirements panel of the Specification Sheet Data pane and can be set independent of one another. Additionally, an option switch that controls which material scheme components common to both chambers follow is present, which affects components such as tubesheets, tubes, and floating heads. By default, common components use the tube side material scheme.
  
  Tubesheets, expansion joints, and pass partitions can now be set in the Material Scheme dialog.
  
  Enabling the material scheme for the heat exchanger chambers allows broader decisions about material selection to be made before getting into the detailed mechanical design of individual heat exchanger components. [62760]
  
  

Specification Sheet Data Pane

• Shell and tube heat exchangers can now be designed within the Specification Sheet Data pane
  Shell and tube heat exchangers can now be designed within the Specification Sheet Data pane of a Division 1 document when the Equipment Type in the Code Requirements pane is specified as Shell and Tube Heat Exchanger. Pressing the Build Heat Exchanger button brings up the Heat Exchanger Wizard populated with the inputs specified in the pane. The following is an overview of the pane’s functionality.
  
  Inputs
  • The Code Requirements pane contains inputs to specify the TEMA class and edition.
  • The Design Requirements pane is broken down into sections for Tube-Side, Shell-Side, Condition Operating, Tubes, Baffles, and Connections inputs.
  • The TEMA Type row allows direct input of a specific TEMA designation or the Edit button can be pressed to bring up a dialog that visualizes the front end head, shell, and rear end head types that can be selected.
  • Heat exchanger defaults files can be used to populate the inputs.
  • Separate material schemes can be selected for tube side and shell side components, and components that touch both chambers can be set to use the shell side material scheme by activating Dual Chamber Components use Shell Side Material Scheme.
  • The tube wall thickness is displayed as Wall Thickness (min) when the Heat Exchanger tube tolerance is set to zero in Set Mode Options-> General 2 and Wall Thickness (avg) otherwise.
  • Kettle shell selections enable the Port Cylinder Inner Diameter input.
  • Expansion joints may be specified as Flexible Shell Element, Bellows, or None. Bellows type selections are defaulted to bellows unreinforced expansion joints.
  • The Tubesheet Mean Metal Temperature is removed when the TEMA edition is specified as none.
  
  
  Set Mode Options -> Exchanger Design
  • Files that have all Design Temperature, Pressure, and Corrosion defaults unchecked are treated as though these defaults are checked to ensure that tube-side inputs apply to apply tube-side components and shell-side inputs apply to shell-side components.
  • Enabling the Channel MDMT option switch removes the MDMT input from the Tube-Side section of the Design Requirements pane, since the tube-side MDMT is set to the shell MDMT.
  • Enabling any of the other defaults does not affect the Design Requirements pane and produces the same behavior it did in previous builds within the Heat Exchanger Wizard.
  [61467]
  
  

Tubesheets

• The front and rear stepped tubesheet sketches now show the gaskets and flanges with the tubesheet
  The Stepped Tubesheet sketch displays how the flanges, gaskets, and stepped tubesheet line up together. This makes it easier to see where the gasket seals and where the steps of the tubesheet should be located with respect to the gaskets and flanges. The sketch matches the UHX tubesheet configuration designated on the General Options page of the Heat Exchanger dialog.

  Any Appendix 2 type flanges, TEMA type backing ring, and dished cover flanges selected to use with the tubesheet are displayed in the Stepped Tubesheet sketch with dimensioning of flange ID, flange OD, and a raised face ID, if applicable.

  Other information in the Stepped Tubesheet dialog includes: Tubesheet thickness, tubesheet diameter, ability to toggle on/off flange dimensions, ability to toggle on/off tubesheet and step dimensions, ability to toggle on/off an exploded view of the sketch, and a fader bar so the flanges will not be seen in the sketch.

  The new Stepped Tubesheet sketch still displays all the information previously displayed in the old sketch. The old sketch displayed the tube side step diameter and step depth, and the shell side step diameter and step depth. [67442]
  
  

Component Tree Pane

• Tubesheet outer diameter
  The outer diameter for tubesheets is now reported in the Component Tree pane when the tubesheet is selected. [67036]
  
  

Heat Exchanger

• Tubesheet thickness message box
  The message box with the message "Increasing the thickness of the shell/channel adjacent to the tubesheet will likely permit a reduction in tubesheet thickness" will now only be displayed when entering the Tubesheet page of the Heat Exchanger Wizard or Heat Exchanger dialog. Previously, this message would be displayed whenever tubesheet calculations were performed. This included opening the file, entering and exiting the tubesheets page, and running the calculations. [67110]
  
  

Heat Exchanger Dialog

• Confirmation when exiting the Heat Exchanger Wizard
  Attempting to exit the Heat Exchanger Wizard will now produce an avoidable warning popup with the message "Are you sure you want to exit the exchanger design? ALL DATA WILL BE LOST." This is to prevent unintentional exits from the Heat Exchanger Wizard. [62533]
  
  
• Defaults files
  The heat exchanger defaults file options have been moved to the new Exchanger Default File dialog. It is accessed via the Heat Exchanger -> General Options -> Exchanger Defaults button. The existing options located in the new dialog are:
  
  
  • The Select Defaults File button
  • The Create New Defaults File button
  • The Update Defaults File as this Exchanger is created option switch
  • The Save current values button
  • The Save Default As... button
  
  [67220]
  
  
• Radial differential thermal expansion consideration
  The option for consideration of radial differential thermal expansion adjacent to the tubesheet per UHX 13.8 and UHX 14.6 can no longer be activated when the heat exchanger does not meet the conditions of applicability of either section. Previously, for an invalid configuration, the values would be included in the report, although the final result would not be impacted. [66770]
  
  

Transitions

• 4.3.12 Cylindrical-to-conical shell transition junctions with a knuckle calculation
  The 4.3.12 shell-to-transition junction with a knuckle calculation is now performed for compact and non-compact knuckles and flares. Previously, knuckles and flares were available in the model but a deficiency was issued that no calculations are provided. [20059]
  
  

• Part 4.3.11.3 length, L_c, check
  The Part 4.3.11.3 length, L_c, check is now performed per equation 4.3.46. [20055]
  
  

Revisions History

• Revision history dialog for class 1
  Switching the Section VIII, Division 2 class will now cause the Revision History dialog to appear. A revision is still added to the file's revision history. [63969]
