API 579 Part 4

• Part 4 metal loss flaws on nozzle outer surface
  Part 4 metal loss flaws can now be applied to the outer surface of nozzles. [75362]
  
  

API 579 Part 9

• Allow user to input different stress profiles for the minimum and maximum fatigue crack growth cycle loadings
  The ability to input different primary and secondary stress profiles for the minimum and maximum fatigue crack growth cycle loadings is now available. This option can be accessed in the Remaining Life Analysis dialog by activating the Change Input Type button. [75516]
  
  
• Handle level 2 crack calculations with an a/c ratio less than the limits in tables of Annex 9B
  API 579 Part 9 level 2 calculations for finite surface cracks with a depth to half-length ratio, a/c, less than the limit in the corresponding tables of Annex 9B are now performed per the steps in 9B.5.10.2.e using the tables of Annex 9B corresponding to the particular stress intensity factor solution. This applies to the limiting flaw curve and fatigue crack growth calculations as well so that neither can be governed by their table 9B a/c geometry ratios. [75499]
  
  
• Option to input crack stress profiles as tabular data
  API 579 Level 2 crack stress profiles can now be input as tabular data. This option can be accessed by selecting the Weight (Numerical Integration) option in the stress tabs of the crack dialog, activating the Enter Stress as Tabular Data option switch, and selecting the Tabular Data button. In this Tabular Stress Data dialog, known stress values may be input at different locations along the crack depth. This location may be input in terms of distance from crack face or ratio of distance from crack face to component thickness. Values between input data pairs will be linearly interpolated. [75134]
  
  
• Weight function stress profile in level 2 crack growth
  The weight function stress profile type may now be selected for the API 579 Part 9 level 2 fatigue crack growth assessment. [75645]
  
  

Component Tree Pane

• Calculation results now available in the Component Tree
  Calculation results for cylinders, transitions, torispherical heads, ellipsoidal heads, hemi heads, and Appendix 2/Part 4.16 flanges are now displayed in the respective component's Properties pane at the bottom of the Component Tree.
  
  A new option switch labeled Auto-Recalculate Component Results is now included in the toolbar found at the top of the Component Tree pane. When active (the default setting), this switch causes the component results to be recalculated each time a new component is selected in the tree. Deactivating this switch will disable automatic recalculation (this may speed up navigation of the Component Tree for complex or large files). Once deactivated, a button labeled Recalculate will appear in the component's Properties pane which triggers a recalculation of results each time it is clicked. [75781]
  
  

Fatigue Assessment

• Include flange bolts in fatigue screening option
  An option switch to Include Bolts in Fatigue Screening is now available in the Fatigue Screening dialog. [75482]
  
  

General

• INSPECT is now a 64-bit native application
  The 64-bit native application can handle larger vessel and exchanger designs due to the increased memory support above the 4 GB limit available for 32-bit applications. [62332]
  
  

Nozzles

• Placement on sump heads
  Nozzles can now be added to sump heads attached to nozzle attachments such as pipes, B16.9 elbows, B16.9 reducers, or B16.9 nozzle tees. Previously, a nozzle could only be attached to a sump head if the sump head was directly attached to the original nozzle. [63840]
  
  
• UG-39(e)(2) multiple openings in flat heads and covers
  The required thickness of flat heads and covers having multiple openings is now multiplied by the factor h when the spacing between any pair of openings is less than twice, but equal to or greater than 1.25 times the average diameter of the pair.

  The UG-39(e) Summary Table in flat head and cover reports provides the following information for each pair of openings, in the new and corroded conditions:

  • Average diameter of the openings, d_ave
  • 1.25 times d_ave
  • 2 times d_ave
  • center-to-center spacing, p
  • ligament efficiency, e
  • factor h
  
  

  The governing h is calculated from the smallest e, unless e is greater than or equal to 0.5 for each pair of openings. [7555]
  
  

Quick Design

• Rings are now available
  Rings can now be placed via Quick Design using three different methods: Auto-spacing, Mirrored Ring Placement, and Set Ring Spacing. Auto-spacing optimally places rings along the vessel such that the required thickness due to external pressure no longer governs. At this time, auto-spacing is only allowed for vessels with cylinders and heads as the only root components. For Mirrored Ring Placement and Set Ring Spacing, use the mouse scroll wheel to change the number of rings to be placed. [75410]
  
  

Saddles

• Wear plate MDMT and material specification
  MDMT calculations are now performed on saddle wear plates. The coincident ratio, per UCS-66(b) for Part UCS materials or 3.11.2.5(a) Step 4 for Table 3-A.1 materials, is that of the shell to which the wear plate is attached. The saddle wear plate material can now be specified for Division 1 in the Saddle dialog. [1716]
  
  

Wind and Seismic

• NBC Canada 2020 Wind and Seismic now available
  Wind and seismic calculations according to the National Building Code of Canada 2020 are now available. Notable changes in the seismic calculations:
  
  1. There is a new calculated parameter: Seismic Category. Horizontal vessels and vessels calculated as equipment which fall in Seismic Category SC1 or SC2 may be exempted from seismic requirements if they are not in the post-disaster importance category (I_e < 1.5) and the Seismic Codes dialog's option switch "Consider 4.1.8.18.(2) exemption from seismic design requirements" is active.
  2. There is a revised calculation method for design spectral acceleration, S(T).
  3. The Seismic Codes dialog now includes new inputs for S_a(T, X_s), where X_s is the site designation, and S_a(T, X₄₅₀); see sentence 4.1.8.1.(2).(c).
  4. The Seismic Codes dialog now includes a new button which opens the NBC Hazard Tool website and automatically looks up seismic location data for the location specified in the dialog.
  
  Notable changes in the wind calculations:
  1. Updated location database table for wind pressure values, including one new location.
  2. The "Very Dynamically Sensitive" deficiency warning is no longer issued when the ratio of vessel height to effective width is greater than 6 due to the new clause regarding human occupancy found in sentence 4.1.7.2.(3).(b).

API 579 Part 10

• Manually input nominal stress for level 1 creep assessment
  An option is now available to manually input a nominal stress for an API 579 Part 10 creep assessment. This Nominal Stress Override can be input in the API 579 Part 10 Creep Assessment dialog and replaces the automatically calculated nominal stress values for attached components. [75739]
  
  

API 579 Part 14

• Additional fatigue screening warnings
  Warnings now appear in the Fatigue Screening summary and Deficiencies summary when the fatigue screening pressure is less than the design pressure, or the fatigue screening temperature is less than the design temperature of the component. In addition, a deficiency now appears when the fatigue screening pressure is greater than the MAWP. [75672]
  
  

API 579 Part 9

• Plane strain and stress options for crack plasticity interaction factor
  Options are now available to select between using plane strain conditions or plane stress conditions, equations 9.13 and 9.14 respectively, for the calculation of the level 2 crack depth and length plasticity interaction factors. These options can be accessed by selecting the Additional Calculation Settings button in the API 579 Crack-Like Flaw dialog for level 2 crack assessments. [75771]
  
  
• Separate user defined material toughness values for crack growth cycles
  Separate user defined material toughness, Kmat, values are now allowed for the minimum and maximum cycle loading conditions in the fatigue crack growth assessment. [75586]
  
  

ASME/ANSI Flanges

• UNS S32205 available
  ASTM A182 F60 and A240 materials are now available for ASME B16.5/16.47 flanges and blind flanges. [71593]
  
  

Component Commentary

• Commentary applied indicator
  A blue indicator now appears in the Commentary button of a component's dialog when a comment has been written. [74148]
  
  
• Commentary in individual component reports
  Individual component commentary now appears in the individual component reports when activated by the checkbox Include Commentary in Component Reports located in Set Mode Options > Reporting > General > Report Options. [70286]
  
  

Deficiencies Summary

• Deficiencies commentary
  Notes can now be added to the Deficiencies Summary. Notes are added by clicking the Commentary button in the Deficiencies dialog. [69058]
  
  

General

• Account Number in the License Management Dialog
  The License Management Dialog now shows the Account Number for the selected license. [75603]
  
  
• Quick Start Guide
  The INSPECT Quick Start Guide is now available in the Help dropdown menu. [75413]
  
  

Nameplate

• Nameplate centerline attachment method
  The centerline of the nameplate is now used as the point of attachment when entering the nameplate offset. Previously, the outer edge of the nameplate was used. [73143]
  
  

Nozzles

• Warning deficiency clarification when pad thickness is greater than the projection available outside the vessel
  When the nozzle pad thickness, t_e, is greater than the projection available outside the vessel, L_pr, and L_pr is less than perpendicular limit of reinforcement, the warning deficiency reported now states "The pad thickness (t_e= value units) is greater than the projection available outside the vessel (L_pr = value units)". Previously, the warning deficiency stated, “Part of the pad thickness is beyond the limits of reinforcement.” [7526]
  
  

Quick Design

• Hillside option for nozzles and couplings located on heads
  A hillside option is now available for nozzles and couplings placed on heads and dished covers using Quick Design. The option can be toggled during initial placement using the Tab key. [75408]
  
  
• Support lugs positioning
  Support lugs can now be added on vertical vessels using Quick Design, setting the distance from datum and the angular position. Once the lugs are placed, the Support Lugs / Ring Girder Support dialog opens to enter the remaining information. [75361]
  
  

Saddles

• Rating mode - base plate length for saddles with 2 ribs
  The base plate length, E, is now correctly displayed in the 3D view and in the Saddle Design Screen 2 dialog after being automatically increased while performing calculations for saddles with exactly 2 ribs which are tapered inward (e.g. when the base plate length is less than the distance between the ribs' two contact points with the vessel). When only 2 ribs are present, the base plate length is automatically increased during calculations to match the width of the ribs' contact points with the vessel because saddle calculations assume vertically oriented ribs. Previously, calculations in the saddle report would correctly reflect this increased length, but the 3D view and the Saddle Design Screen 2 dialog would not. [5790]
  
  

Seismic

• NBC 2005-2015 exemption from seismic requirements
  An option switch permitting the consideration of NBC 2010-2015 sentence 4.1.8.18.(2) (4.1.8.17.(2) in NBC 2005) is now available in the Seismic Codes dialog for horizontal vessels and vessels calculated as equipment. When this option switch is active, the vessel will be exempted from seismic requirements only if both of the following conditions are met:
  
  1. I_e*F_a*S_a(0.2) is less than 0.35
  2. Importance Factor, I_e, is less than 1.5 (so that the vessel is not considered to be in the "post-disaster" importance category; see Table 4.1.2.1.)
  
  [59331]
  
  

Set Mode Options F7

• Nozzle radiography defaults
  Default longitudinal and circumferential radiography settings for nozzles are now available in the Set Mode Options dialog on the Nozzles 2 page. This default applies to the nozzle attachment radiography settings as well. [73255]
