Air cooled heat exchangers designed per Appendix 13 now available The design of air cooled heat exchangers per Appendix 13 is now available by selecting the Air Cooled Heat Exchanger icon in the main component toolbar, by selecting the Component -> Air Cooled HX menu item, or by entering the Ctrl+Shift+U hotkey shortcut inside of a blank Division 1 document.
Highlights of the new design feature include:
Design through the Design Requirements pane instead of dialogs for immediate feedback on required thicknesses.
Figure 13-2(a) configurations (1), (7), (8), (9), and (10) available.
Tubesheet grooves and plugsheet counterbores may be specified through the Multidiameter Hole Pattern dialog.
Material selection follows the material scheme, but individual header plates may be changed through the Air Cooled Heat Exchanger Materials dialog.
The Identical Headers switch allows for the inputs to only be entered once when the inlet and return headers are identical.
The Stay-to-End Plate Welds are Full Pen. option switch allows for the end plate short side length to be reduced to the maximum compartment height inside of the end plate calculations when stay plates are present.
The consideration of API 661 requirements may be activated by selecting the Apply API 661 Requirements option switch inside of the Code Requirements portion of the Specification Sheet Data pane or in >Set Mode Options -> Defaults -> Appendix 13.

Elbow Connections
Elbow Connections dialog replaced with individual component dialogs for nozzle connections The Elbow Connections dialog is removed in favor of individual component dialogs for nozzle connections. Highlights of the component dialogs include:
The Standard Components toolbar features nozzle piping, B16.9 elbows, B16.9 reducers, B16.5/16.47 flanges, B16.9 pipe caps, and B16.11 couplings
Design conditions, corrosion, and unsupported length can be specified per component
Maximum number of nozzle connections is increased to five, excluding flange pairs
[65478]
Nozzles
B16.9 reducers now available for nozzle connections The option to add B16.9 reducers to nozzles is now available and can be used in unison with other nozzle connections such as nozzle pipe, B16.9 elbows, B16.5/16.47 flanges, and all head types. The available material list for the reducer is limited to the materials listed in ASME B16.9. The User-Defined Material option may be used but is limited to fitting product forms. Reducers may be added to the model using the new Quick-Design feature, the Nozzle menu option, or from the reducer dialog. [61631]
PCC-1
ASME PCC-1 Appendix O Analysis of bolted joint flange assemblies per ASME PCC-1 Appendix O is now available.
PCC-1 Appendix O provides guidance on determining the appropriate assembly bolt stress with due consideration for joint integrity.
Two approaches are available: the simple approach, and the joint approach.
With the simple approach, an appropriate bolt stress is determined based off of the target stress of the gasket, and converted to a target torque.
With the joint approach, the following conditions are considered before arriving at a target torque:
Sufficient gasket stress to seal the joint
Damage to the gasket
Damage to bolts
Damage to the flange
PCC-1 Appendix O can be activated for custom flanges in the Bolt Data->ASME PCC-1 Appendix O Bolt Stress Determination section of the dialog; navigating to the next page will bring up the ASME PCC-1 Appendix O Variables dialog.
Activating this option for standard flanges will reveal the ASME PCC-1 Inputs button which will navigate to the same ASME PCC-1 Appendix O Variables dialog that is available for custom flanges.
The results of the PCC-1 Appendix O calculations can be found in the report for the flange it is applied to under the heading "ASME PCC-1 Appendix O Simple Approach" or "ASME PCC-1 Appendix O Joint Component Approach". The target torque is also included in the results summary for custom flanges.
PCC-1 Appendix O is not available for the following components:
Flanges with full face gaskets
Floating tubesheet backing rings (only available for the mating component)
Shell flanges enclosing a Figure UHX-14.3 Configuration D floating tubesheet (TEMA Type W)
Rear shell flanges used as a lantern ring assembly around Figure UHX-14.3 Configuration A floating tubesheets (TEMA type P)
Piping flanges

Quick Design
Vessel Quick Design Quick Design is a new feature for Build 7900 intended to streamline the vessel design process to quickly and efficiently add and size components. When Quick Design mode is active, most components may be placed visually without the need to click through a dialog, they are subsequently sized according to the design conditions.
Quick Design mode may be toggled on and off by using the first button on the Component Toolbar, or by pressing Ctrl + Q. Design preferences have also been added to Set Mode Options under Nozzles 1 -> Quick Design Mode Behavior, where uniform thickness nozzle sizing and automatically adding B16.5/16.47 flanges to the end of a nozzle can be specified.
The following components are compatible with Quick Design:
Cylinders
Transitions
Hemispherical, torispherical, and ellipsoidal heads
Welded covers
Bolted covers
Appendix 2 flanges
B16.5/16.47 flanges
Nozzles
B16.11 Couplings
Sump heads
Nozzle pipe
B16.9 elbows
B16.9 reducers
Pipe caps
Skirts
Saddles
Several of the above components utilize an Overlay dialog so that additional design information can be input to limit the need to make additional changes in each component's dialog. The following specifications can be made in the component Overlay dialog:
Appendix 2 flanges:
Flange type
Sketch type
B16.5/16.47 flanges:
Flange type
Welded covers:
Sketch type
Corner joint
Nozzles:
NPS
Nozzle type
Add flange option switch
Couplings:
NPS
Class
Additional Quick Design behavior:
Appendix 2 and B16.5/16.47 flange pairs can be inserted between vessel body seams
After an Appendix 2 flange is placed and fully designed, flanges added after the fact will retain the same dimensions and design parameters if the flange is attached to a component the same size and utilizes the same flange type
B16.5/16.47 flange class automatically set based on design conditions
Mouse scrolling allows for quick changes during component placement for B16.9 elbow placement angle, nozzle pipe length, B16.9 reducer size, nozzle size and type, and coupling size and class.

RT Marking
Spot UW-11(a)(5)(b) only circumferential seam radiography option now available The option to specify circumferential seam radiography as Spot UW-11(a)(5)(b) only is now available in order to obtain a UG-116(e) RT2 marking. Previously, a Spot UW-11(a)(5)(b) option was available but conformed to both spot per UW-11(a)(5)(b) and spot per UW-11(b), which should have resulted in a UG-116(e) RT4 marking. This option is still available in the circumferential seam radiography dropdown as Spot UW-11(b)&UW-11(a)(5)(b). [66177]
Additional Features
ASME/ANSI Flanges
Code Case 2901 for integral forgings Code Case 2901 is now available for long weld necks and set in variable thickness nozzles with the Standard (from Catalog) configuration. [65364]
Bill of Materials
Couplings table added The Bill of Materials now includes a separate table for couplings. The nominal pipe size, class, and end connection are reported in the Type column. [65609]
General Arrangement Drawing
Text size increased The text size is increased inside of the General Arrangement Drawing. [65233]
Legs
Determining WRC governing case made more robust Primary stress is now considered in addition to combined stress when determining the governing WRC case reported in the legs report. Additionally, when two legs have the same corresponding stress values, both are now reported. Previously, only combined stress was considered and a maximum of one governing case was reported. [65081]
Material Scheme
B16.11 couplings added B16.11 couplings are now available in the material scheme. [66213]
Nozzles
Allowable stress criteria change for nozzles calculating external pressure outside scope of Appendix 1-10 - 2015 and earlier code editions Nozzles that fall outside the scope of Appendix 1-10 and determine the external pressure calculations using Division 2 Part 4.5 rules are now compliant with the Division 2 allowable, Sc in the calculation of the maximum local primary membrane stress, PL. Previously, the allowable stress criteria 1/2*min(S, Sc) was used as part of a U2-(g) analysis. To maintain consistency with Division 2 and for conservative purposes, Sc is now used. [65097]
Figure UW-16.2 Sketch (K) configuration available for set in couplings Set in couplings can now be attached without lower groove welds as specified by UW-16.2 Sketch (K) for all available coupling types and end connections. A deficiency is reported for this coupling configuration if it does not conform to the conditions specified by UW-16(f)(3)(a). [56490]
Nominal pipe size maintained when switching between nozzle styles Nominal pipe size now remains the same when switching between nozzle styles in the Nozzle dialog that have standard nominal pipe sizes available. If a nominal pipe size less than the minimum size available for a specific style is chosen before switching to that style, the minimum size will be selected by default during the switch. Uniform thickness nozzles and elliptical manways will keep the same dimensions instead of choosing a default size but will remember the last nominal pipe size chosen when switching back to a nozzle style with standard sizing. [66168]
Option to specify set in threaded couplings Threaded couplings can now be specified as set in. The following are the changes accompanying this attachment type.
ASME B16.11 threaded full and half coupling dimensions are available in the ASME B16.11 Threaded Coupling Look-Up dialog brought up from the Standard Size Look-Up button.
Custom overall coupling lengths can be specified by activating the Specify Custom Length option in the Nozzle dialog.
Full and half coupling types as well as nominal pipe size and class defaults can be specified in the Nozzles 2 page of the Set Mode Options dialog.
Set in couplings can be attached with a combination of full or partial penetration lower groove welds and internal projections with lower fillets. These configurations conform to UW 16.1 sketches (y-1), (y-2), (z-1), and (z-2). In addition, the option to specify no lower groove weld is available to conform to UW 16.2 sketch (k).
[65360]
Option to specify socket welding couplings Set in and set on couplings can now be specified with socket-welding end connections. The following are the changes accompanying this end connection type.
ASME B16.11 socket welding full and half coupling dimensions are available in the ASME B16.11 Socket-Welding Coupling Look-Up dialog brought up from the Standard Size Look-Up button.
The socket depth is accounted for in the unsupported length when pipe is attached to couplings in the Nozzle and Nozzle Pipe reports.
Pipes are now inset the length of the socket depth specified in ASME B16.11 when rendered in the solid model.
Custom overall coupling lengths can be specified by activating the Specify Custom Length option in the Nozzle dialog. This does not alter the socket depth.
Full and half coupling types and set in and set on attachment types can be specified for socket welding couplings and these defaults can be specified in the Nozzles 2 page of the Set Mode Options dialog.
Pipes are the only available attachment for socket-welding couplings and can be placed on the coupling through the Nozzle Connection button in the second page of the Nozzle dialog or through the use of the pipe Quick Design button.
[65988]
Required nozzle wall thickness deficiency specifies condition Nozzles reporting a UG-45 required nozzle wall thickness deficiency will now specify all conditions for which it is present. This includes internal pressure, chamber MAWP, chamber MAP, external pressure, MAWP, MAP, or MAEP. Previously, a single deficiency was reported without the condition(s) for which it was associated. [65910]
Set in uniform thickness nozzles made with threaded coupling dimensions recognized as legacy couplings Beginning in Build 7900, new couplings may only be added by specifying the Coupling style in the Nozzle dialog. Existing set in Uniform Thickness style nozzles with dimensions chosen from the Threaded Couplings list in the Standard Size Look-Up dialog are now considered legacy couplings. This internal setting will persist until the nozzle is next edited, and will maintain a coupling style description in the Bill of Materials and other reports. Note that these nozzles will now be reported in the Nozzles - Couplings table in the Bill of Materials instead of the Nozzles table. Should any such nozzle need to be edited, it is recommended that the nozzle Style option be changed to Coupling at that time, or the nozzle will no longer be considered a coupling. [66075]
Set on coupling attachment updated The set on coupling nozzle attachment type now has updated ASME B16.11 data for length and thickness values for full and half coupling types as well as threaded and socket-welding end connection types. The overall length of the coupling itself can now be specified by activating the Specify Custom Length option and inputting a value for Overall Length. Set mode defaults are now available in the Nozzles 2 page to specify the size and configuration of set on couplings as well. [65556]
Standard Size Look-up dialog improved The following improvements are now available for the Standard Size Look-up dialog for Uniform Thickness, Studding Outlet, and Coupling nozzle types:
The look-up dialogs for uniform thickness nozzles and couplings now only show standard sizes unique to the corresponding nozzle type. Previously, uniform thickness standard sizes could be chosen for couplings and coupling standard sizes could be chosen for uniform thickness nozzles.
The look-up dialog for couplings now lists the End-to-End Length of each standard size in addition to the Wall Thickness and Outer Diameter dimensions that were previously available.
The look-up dialog for studding outlets now lists the Pad Thickness of each standard size in addition to the Wall Thickness and Outer Diameter dimensions that were previously available.
The Standard Size Look-Up dialog for couplings is now separated into the ASME B16.11 Threaded Coupling Look-up dialog and the ASME B16.11 Socket-Welding Coupling Look-up dialog which corresponds to the end connection chosen for the coupling.
[6402]
Welds increased to pass weld path analysis Nozzles with weld sizes that cause the weld path analysis to fail now are now automatically increased sufficiently to pass. Additionally, this increase now accounts for outer corrosion on the parent component. [65199]
Set Mode Options F7
Default material scheme A default material scheme can now be defined in Set Mode Options -> Defaults -> General -> Material Scheme. [64471]
Specification Sheet Data Pane
Diameter input in design requirements panel Vessel diameter is now available as an input in the Design Requirements panel of the Specification Sheet Data pane. [65651]
First keystroke functionality The first keystroke entered for an input in the Specification Sheet Data Pane is no longer overwritten by subsequent keystrokes. As a result of this change, pressing tab to navigate through the pane will no longer automatically highlight the current input; typing while a particular input is selected will still correctly enter text. [63424]
Wind Loads
NBC Canada 2015 errata 2018 The 2018 errata for NBC Canada 2015 eliminates the CeH factor in the expression defining V in part 4.1.7.8 (4). [66514]
XML
Lower groove weld bevel out The draw lower groove weld bevel out option for nozzles is now reported in the XML. [65991]
Heat Exchanger
Tubes and Shell
Tube material property switches Impact testing, postweld heat treatment, normalization, and fine-grain practice can now be specified for tubes. The switches for these properties are available in the Tubes and Shell page of the Heat Exchanger dialog.
A warning is now reported in the Deficiencies Summary stating "Tubes: PWHT may be required if any welding is performed on the tubes. (warning)," when postweld heat treatment would normally be required for a tube material. Additionally, the postweld heat treatment switch for tubes will not toggle when a global postweld heat treatment change is made. [54584]
