COMPRESS




  • ASME/ANSI Flanges

    • Bore diameter input now available
      A Bore, B diameter input is now available on the Select ASME B16.5/16.47 Flange dialog for applicable flange types. In addition, the ASME B16.5/16.47 flange's parent component now considers the flange hub thickness in PWHT and MDMT determinations. [56127]

    • Consider external loadings switch
      The Consider external loadings on flange MAWP rating option in the Select ASME B16.5/16.47 Flange dialog is now active by default for new body flanges on vertical vessels. In addition, a warning is now presented in the Deficiencies Summary report when external loads are present but the option is not active. [55983]

    • Identifier of attached component is now reported
      The identifier of the attached component and location is now reported in the echo section of ASME B16.5/B16.47 body flanges. [56528]

  • Appendix 14

    • Longitudinal joint efficiency
      A longitudinal joint efficiency input is now available for the large central opening in the Appendix 14 dialog. [55627]

    • Nozzles with welded and seamless product forms
      Appendix 14 nozzles constructed of a welded and seamless product forms may now be calculated as the welded product form by deselecting the Seamless Product Form option and entering the required nozzle joint efficiency. Previously, welded and seamless product forms were always calculated as seamless. [55626]

  • Appendix 2 Flanges

    • Hydrotest stress
      The governing stress during hydrostatic or pneumatic testing is now the largest of the ratio of SH, SR, ST, (SH+SR)/2, or (SH+ST)/2 to allowable, where the hub stress allowable is 1.5*%yield*Sy, and the allowable for all other stresses is %yield*Sy. Previously, the governing stress was specified as the largest ratio of (Max(SR,ST) + SH) or SH to allowable. [55196]

    • Rigidity Factor recommended value check
      The second page of the Flange dialog now includes a check which offers to correct the Rigidity Factor to the suggested Code value when the Flange Type is changed from loose to integral and vice versa. A warning is now presented in the Deficiencies Summary report when the flange Rigidity Factor does not match the recommended value. [54675]

  • Clip/Lug

    • Copy last now available for clips and lugs
      A new Copy Existing Clip/Lug button is located on the Clips/Lugs dialog to copy parameters from any existing clips or lugs on the vessel. [4641]

  • Custom Flanges

    • Minimum reporting now available
      A minimum reporting option is now available for custom flanges in Set Mode Options -> Reporting -> General -> Component Minimum Reports. When this option is active, custom flange reports only report the Stress Summary, Bolt Summary, and Rigidity Summary. [55788]

    • Summary tables added
      The tables Stress Summary, Bolt Summary, and Rigidity Summary are now available in custom flange reports. [55764]

  • Cylinders

    • Pipe minimum thickness added to echo section
      Cylinders constructed from pipe materials now include a Pipe Minimum Thickness line inside of the echo section of the report. This is a reporting change only as the pipe tolerance was already considered in the detailed calculations. Pipe tolerance may be turned off by entering Set Mode Options -> Calculation -> General 2 and activating the Cylindrical shells made form pipe are entered as minimum thickness option inside of Material Thickness Options. [7620]

    • UG-28(c) reporting improvements
      The yield stress for a Do / t ratio less than 10 is twice the B value from the vacuum chart per UG-28(c)(2)(b). The determination of the yield stress is now reported in the maximum allowable external pressure section of the cylinder report. [55649]

  • Dished Covers

    • Material Properties buttons now available
      Separate Material Properties buttons for the dished cover and dished cover flange are now available in the Dished Covers dialog. [56402]

  • Elbow Connections

    • Elbow Connections option for nozzles
      The option to add elbow connections to nozzles is now available. These connections may consist of an ASME B16.9 elbow, pipe spools, as well as attached ASME B16.5/16.47 flanges. The elbow connection feature can be accessed from the Nozzle menu option, using the keyboard shortcut Ctrl+F2, or from the Elbow Connections button in the nozzle dimensions dialog.

      Highlights of the new design feature include:
      • The connection to the nozzle may consist of a single pipe, a single elbow, a pipe with an elbow attached, or an elbow with a pipe attached.
      • Available elbow types are from ASME 16.9 and include i) Long Radius 90°, ii) Short Radius 90° iii) Long Radius 45° iv) Long Radius increasing and reducing.
      • The available material list for the elbow is limited to the materials listed in ASME 16.9. The User Defined Material option may be used but is limited to fitting product forms.
      • The total unsupported length of the nozzle connection assembly is determined based on the actual lengths of the individual components. Any flanges included in the assembly are considered as lines of support. An option to specify a custom unsupported length is available in order to account for additional piping that may be connected to the vessel.
      • Default settings may be specified on the new Set Mode -> General -> Elbow Connections page. This includes a switch to include elbow connections past the first seam as defined in ASME VIII Division 1 paragraph U-1(e)(1) and Section VIII Division 2 paragraph 1.2.3(a) in the vessel scope. When this switch is not active the vessel scope is determined based on the first flanged joint (U-1(e)(1)(c)); if no flange joint exists, the vessel scope is taken to the first circumferential seam (U-1(e)(1)(a)).
      [53005]

  • Forms

    • Flat heads with large single circular central openings
      Flat heads with large single circular central openings are now automatically populated in the appropriate tables inside ASME Forms. [55559]

  • General

    • Enhancements to main window style
      Highlights of the new main window style include:
      • Additional colors are available by selecting Background Color in the Window menu item.
      • The Project Window supports the dockable pane feature, allowing the options to float, close, hide, and dock to the main window.
      • Toolbars now support docking and scale with magnification.
      • Tooltips display icons when available.
      • The Status Bar provides helpful tips when hovering over buttons.
      [53160]

    • Bolts now recognized by unique identifiers
      Bolts are now internally recognized by unique identifiers rather than by bolt nominal size. Previously, bolts with an identical nominal size but potentially different characteristics could mistakenly override intentional selections. [5686]

    • Design pressure only now permitted in rating mode
      All maximum pressure option switches on the Set Mode Options -> General 1 page may now be deactivated when in rating mode. This allows the rating mode to be utilized to review a design at the input internal and/or external design pressure values. Previously, at least one of the maximum pressure option switches had to be active. [55827]

  • General Arrangement Dwg

    • Dished covers
      Dished covers are now displayed in the General Arrangement Drawing. [5799]

    • Lift lugs located on transitions
      Lift lugs located on concentric transitions now correctly follow the angle of the transition in the General Arrangement Drawing. [5997]

    • Stiffening rings
      Stiffening rings are now displayed with dimensions in the General Arrangement Drawing. [5916]

  • Hydrotest Corroded

    • Shop test note no longer reported
      The note "The shop test condition has not been investigated for the Chamber bounded by xx and yy" is no longer reported in the Corroded Test Report. Previously, the Corroded Test Report always reported this note for each chamber, which caused confusion as the shop test condition is examined in the Test Report. [54328]

  • Legs

    • Oblique direction now considered
      For pipe support legs specified with an eccentricity of zero, the oblique direction between the legs is now investigated for wind and seismic loads. [56229]

  • Lift Lugs

    • Calculation no longer performed for tail lugs off of perpendicular
      A deficiency is reported and tail lug calculations are no longer performed when the tail lug location is more than 10° off of perpendicular to the trunnion or top ear lug location. This angle is not considered in the tail lug analysis. [56345]

  • Long Seams

    • Support skirts and intermediate skirts with skirt openings
      The Adjust Starting Angle of each Shell Course to avoid Attachments and Adjacent Seams option inside of the Long Seam Wizard dialog now considers support skirts and intermediate skirts with skirt openings. [53118]

  • MDMT

    • MDMT rating of variable thickness nozzles
      Independent MDMT ratings are now determined for the heavy barrel and nozzle neck sections of Type 9 and Type 10 nozzles for carbon and low alloy steel materials. Previously, the MDMT rating was conservatively based on the governing thickness at the shell intersection coupled with the stress ratio at the thin end when the vessel’s stress ratio was not used per ASME Interpretation VIII-1-01-37. This could have resulted in impact testing when not required. [7021]

  • Nozzle Schedule

    • Heads and welded covers now included
      Heads and welded covers attached to nozzles are now included in the Nozzle Schedule report. These attachments are listed under the same drawing mark as the parent nozzle. [56391]

  • Nozzle Summary

    • Pipe mill tolerance note
      The Nozzle Summary report now displays a note in the Definitions table indicating that the 12.5% pipe thickness tolerance is accounted for in the nozzle required thickness value when any nozzles are made from pipe material. This note does not appear and the mill tolerance is not considered when the Set Mode Options -> Nozzles -> Nozzles made from pipe are entered as minimum thickness option is active. [5149]

  • Nozzles

    • ASME B16.5/16.47 flange connections with heads attached to a nozzles
      The option to add a mating ASME B16.5/16.47 flange connection with a head at the nozzle free end circumferential seam is now available. If an ASME B16.5/16.47 flange is already attached to a nozzle, the mating flange will automatically be added to the new head. If an ASME B16.5/16.47 flange is added to an existing nozzle with a closure head already in place, a pair of mating flanges is added. The mating flange is an exact copy of the nozzle flange and is specified in the Select ASME B16.5/16.47 Flange dialog inside of the Nozzle dialog. [55246]

    • Maximum pressure options on the General 1 page of the Set Mode Options dialog now apply to nozzles
      The nozzle calculation settings are simplified by using the maximum pressure options on the General 1 page of the Set Mode Options dialog. This avoids complications when the maximum pressure calculation options on both the General 1 and Nozzles pages were in conflict. The design option Design P, Find Nozzle MAWP&MAP as well as the Rate Nozzles for options are no longer available on the Nozzles page. Nozzle maximum pressures are now calculated based solely on the option(s) selected on the General 1 page. The Reporting page is now more flexible and allows nozzle calculations to be reported at design pressure, maximum pressure, or both. [56317]

    • Available nozzles when adding heads
      Nozzles with attached heads are no longer listed in the Select Nozzle dialog when a new head is added to the vessel. [56061]

    • Circumferential seams at the end of nozzles is now considered in MDMT and PWHT governing thickness
      The circumferential seams at the end of nozzles are now considered in determining the governing thickness for MDMT and PWHT requirements for carbon and low alloy steel materials. If there is no attachment at the end of the nozzle, the circumferential seam is still ignored for determining the governing thickness for PWHT. Previously, only the nozzle intersection with the shell was considered. [55840]

    • Division 2 rules now used as a U-2(g) analysis for the external pressure condition when Rn/R > 0.7
      For a large opening with a Rn / R ratio greater than 0.7, the Division 2 rules are now automatically used as a U-2(g) analysis for the external pressure design condition when the ASME 2013 Edition is selected and the option switch Use Appendix 1-10 for large opening is active in the Nozzle Calculation Options dialog. Previously, a deficiency was reported indicating a U-2(g) analysis is required. [53911]

    • Internal pressure calculations using Appendix 1-2 formulas
      The option to calculate nozzles under internal pressure using the Appendix 1-2 formulas is now available by activating the Force Appendix 1-2 formulas for nozzle calculations option inside of the Set Mode Options -> Calculations -> Nozzles page. [56001]

    • Longitudinal seam now considered in MDMT and PWHT governing thickness for plate product form
      The longitudinal seam of nozzles constructed from plate is now considered in determining the governing thickness for MDMT and PWHT requirements for carbon and low alloy steel materials. Previously, only the nozzle intersection with the shell was considered. [7022]

    • Material Properties button added
      Material Properties buttons for the nozzle and pad material are now available in the Nozzle dialog. [55320]

    • MDMT rating no longer considered in determing nozzle MAWP
      The MDMT rating is no longer considered when determining the MAWP rating of a nozzle. The nozzle MDMT is now always calculated at the chamber MAWP. Previously, the nozzle MAWP was decreased, if required, to satisfy the design MDMT. [56150]

    • Minimum pipe and tube thicknesses reported
      The nominal thickness of pipes and tubes adjusted for pipe tolerance is now reported in the echo section of nozzle reports for nozzle Type 1 through Type 8 constructed from pipe or tube that is not entered as minimum thickness. [56028]

    • Tangential nozzles inserted through cylinder walls
      The maximum Offset CL to CL, Lo for offset nozzles inserted through cylinder walls now allows for the inner radius of the nozzle to be tangent with the inner radius of the cylinder. In Build 7500, the largest offset allowed was for the outer radius of the nozzle to be tangent with the inner radius of the cylinder due to a calculation issue. [55745]

  • Saddles

    • Base plate width sanity check
      A dialog sanity check in the Saddle Design Screen 2 dialog now ensures that the Base Plate Width (F) is equal to or larger than the Saddle Width when the Web/Rib Style is set to Web at Edge. Files that do not pass this sanity check will be automatically corrected upon loading. The increase in the base plate width can affect the saddle base plate thickness check calculation. Previously, the saddle web could be disconnected from the base plate. [4763]

    • Wear plate width sanity check
      A dialog sanity check in the Saddle Design Screen 2 dialog now ensures that the Wear Plate Width (Wp) is equal to or larger than the Base Plate Width (F) when the Web/Rib Style is set to Web at Edge. Files that do not pass this sanity check will be automatically corrected upon loading. Previously, the saddle web could be disconnected from the wear plate. [56031]

    • Weight-only condition with wind present
      The weight-only condition is now investigated when wind is present, except in the case of a Division I vessel with a UG-23(d) Stress Increase factor of 1. [51317]

  • Set Mode Options F7

    • Default material setting for ASME B16.9 fittings
      The default material setting for ASME B16.9 pipe caps and elbows may now be selected in Set Mode Options -> Defaults -> Elbow Connections under the B16.9 Fitting Material dropdown. The available materials for B16.9 pipe caps and elbows are limited to the fitting materials in ASME B16.9. Previously, the default material for pipe caps was set to SA-234 WPB. [55917]

  • Support Lugs

    • Anchor bolt design now available
      Anchor bolt design is now available for support lugs. Anchor bolt properties may be specified in the Supports Page of the Vessel Wizard dialog, or in the Support Lugs / Ring Girder Support dialog. Tensile loading calculations are now provided at the bottom of Support Lugs reports. [6325]

  • Support Skirts

    • Weight-only condition with wind present
      The weight-only condition is now investigated when wind is present, except in the case of a Division 1 vessel with a Skirt/Legs/Saddles Stress Increase factor of 1 in the Set Mode Options -> Calculation -> General 1 dialog. [54731]

  • Toolbars

    • Solid model with Show Internals option
      The Show Internals option now remains consistent between the 3D view and the solid model view. [55894]

    • View Orientation option on Camera toolbar
      The View Orientation drop-down on the Camera toolbar allows for quick positioning of the vessel in the isometric, front, left, right, top, bottom, and back orientations. [56494]

  • Vessel Wizard

    • ASCE&IBC Risk (Occupancy) Category
      The Risk (Occupancy) Category is now available in the Vessel Wizard and Vessel Wizard Defaults dialogs for ASCE and IBC building codes. [55821]

  • Wind and Seismic

    • 2015 International Building Code
      Wind and seismic calculations in accordance with the 2015 International Building Code are now available. IBC 2015 adopts the calculations and references from the wind and seismic provisions of the ASCE 7-10 building code. [55513]

    • ASCE&IBC Risk (Occupancy) Category
      The seismic code Risk (Occupancy) Category is now set to III when activating the Lethal Service switch in the ASME Codes dialog. Previously, only the wind Risk Category was changed upon activation of lethal service. In addition, a warning is displayed in the Deficiencies Summary report when the seismic and wind Risk Categories of a horizontal vessel do not match. [55576]

  • XML

    • XML and XML3D formats extended
      The XML and XML3D formats now include the following:
      • material P No
      • material Group No
      • leg brace material name

Heat Exchanger

  • Dished Covers

    • Identifier of the attached component now reported
      The identifier of the attached component is now reported in the echo section of the dished cover report. [56516]

  • Expansion Joints

    • Flanged and flued expansion joint FEA analysis per TEMA 9th Edition
      Flanged and flued expansion joint Line Element FEA analysis per the TEMA 9th Edition is now available. This analysis calculates accurate spring rates and the resulting stresses due to displacement for each design condition and load case. The FEA analysis is performed when the TEMA 9th Edition is selected and User Defined Expansion Joint Spring Rates (Sj) are not defined. [53942]

  • Tubesheets

    • MDMT deficiencies for UHA, UHT and UNF materials
      MDMT deficiencies for tubesheets constructed of UHA, UHT, and UNF materials are now generated as applicable. Previously, only MDMT deficiencies for tubesheets constructed of UCS materials were generated. [56124]

  • XML

    • XML and XML3D formats extended
      The XML and XML3D formats now include the TEMA size and numbering designation (e.g. "SIZE 20-120 TYPE BEL"). [56009]

Division 2 2007 Edition and Later

  • Forms

    • Manage Forms option
      ASME A-1 and A-2 forms are now available in the Manage Forms dialog. [56388]

  • Nozzles

    • Echo section now always displayed in two tables
      The nozzle echo section is now always displayed in two separate tables. This prevents the echo section from wrapping onto the second page in PDF reports. Previously, the echo section was only broken into two tables if a pad, flange, or studding outlet were present. [56029]

  • Transitions

    • Part 4.3.12.2 and 4.3.12.3 deficiencies clarified
      The deficiencies "4.3.12.3: Mandatory calculations for a cylinder-to-cone junction with a flare are not currently enabled. Independent investigation is required." and "4.3.12.2: Mandatory calculations for a cylinder-to-cone junction with a knuckle are not currently enabled. Independent investigation is required." now read "4.3.12.3: Mandatory calculations for a cylinder-to-cone junction with a flare are not included. Independent investigation is required." and "4.3.12.2: Mandatory calculations for a cylinder-to-cone junction with a knuckle are not included. Independent investigation is required." This change was made to clarify that the calculations are not currently available instead of a feature that can be enabled or disabled. [56016]
