Material selection follows the material scheme, but individual header plates may be changed through the Air Cooled Heat Exchanger Materials dialog.Tubesheet grooves and plugsheet counterbores may be specified through the Multidiameter Hole Pattern dialog.Design through the Design Requirements pane instead of dialogs for immediate feedback on required thicknesses.Highlights of the new design feature include: 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.Diameter input in design requirements panel.Welds increased to pass weld path analysis.Set in uniform thickness nozzles made with threaded coupling dimensions recognized as legacy couplings.Required nozzle wall thickness deficiency specifies condition.Option to specify socket welding couplings.Option to specify set in threaded couplings.Nominal pipe size maintained when switching between nozzle styles.Figure UW-16.2 Sketch (K) configuration available for set in couplings.Allowable stress criteria change for nozzles calculating external pressure outside scope of Appendix 1-10 - 2015 and earlier code editions.Determining WRC governing case made more robust.

Spot UW-11(a)(5)(b) only circumferential seam radiography option now available.B16.9 reducers now available for nozzle connections.Elbow Connections dialog replaced with individual component dialogs for nozzle connections.Air cooled heat exchangers designed per Appendix 13 now available.
