Technical Changes in PV Elite and CodeCalc 2015, SP1

The following list details changes to PV Elite and CodeCalc (Version 17.00.01), which may affect the numeric results:

  • Fixed an issue in PV Elite in which the software incorrectly interpolated allowable stress values for materials in the metric material database. Previously, when you selected Use Metric ASME Material Database on the Configuration dialog, the software computed an incorrect value for Allowable Stress, Operating of a metric material if you were changing the design internal temperature. The software now correctly calculates stress values for materials in the metric material database.
  • The option to include Japanese materials was removed from the Default Value Settings tab of the Configuration dialog. 

Revisions in PV Elite and CodeCalc 2015, SP1

The following list details revisions made to PV Elite and CodeCalc Version (17.00.01).
Productivity

  • Fixed an issue in CodeCalc in which the software stopped functioning after deleting a WRC107 job in a specific file. Previously, if you deleted a WRC107 job using the Delete Selected Items icon in the Local Stress Analysis file and then immediately selected another WRC107 job, the software would stop functioning. The software has been updated and now allows you to delete a WRC107 job and select a new WRC107 job without incident.
  • Fixed an issue in PV Elite in which the software would not open a template file without generating an error message using the New > From Project Template option. Previously, the software displayed an error message when attempting to open a template file if you selected Do Not Compress Input Files in the Configuration dialog. The software now opens template files regardless of the configuration options selected. 
  • Updated CodeCalc to make Analyze unavailable when no components are available. Previously, Analyze was available upon opening the software and after you deleted all the available components. The software has now been updated to make Analyze unavailable both when the software initially opens and upon removal of all components.
  • Updated PV Elite by including an additional option in ASME Weld Type on the Nozzle Input/Analysis dialog. A new a-1 option has been added to ASME Weld Type to allow you to select the A-1 sketch as a weld type per ASME VIII Div 1 Fig UW-16.1. 
  • Fixed an issue with creating a new tubesheet in PV Elite when using Windows 8 or Windows 8.1. Previously, when you selected Tubesheet Analysis to create a new tubesheet, the software stopped functioning. However, the software functioned as expected when you selected an existing tubesheet. You can now successfully create new tubesheets when using the Windows 8 or Windows 8.1 operating system.
  • Fixed units issue in PV Elite when you customized the Input Processor dialog box size. Previously, if you selected to change the units after you reduced the Input Processor dialog box to where the Units/Code panel displayed as a dropdown box, the software stopped functioning. The software no longer changes the Units/Code panel into a dropdown box, and the issue was resolved.

Calculations

  • Fixed an issue in CodeCalc regarding metric unit conversions for rectangular vessel calculations. Previously, the software did not convert the corrosion value in rectangular vessel calculations from metric to imperial units in the equation substitution. The software now converts all values to the correct unit. This did not affect the results. 
  • Fixed an issue in PV Elite regarding certain tubesheet bending stress calculations. Previously, the software used incorrect load cases in tubesheet calculations for U-Tube tubesheets with the full vacuum case on both sides. The incorrect calculations affected the tubesheet bending stress calculation results on the ASME TS Calc report. The software now sets the appropriate load case for vessels with different vacuum pressures and displays accurate calculations for all tubesheet bending stresses.
  • Fixed an issue in PV Elite in which the software incorrectly calculated the values for Qs and Ql for specific vessel elements in the Division 1 code. Previously, when a negative axial force was applied to an element below a cone below the point of support, the software incorrectly calculated the Qs and Ql calculations on the Element and Detail Weights report. The software now correctly calculates the values for Qs and Ql. 
  • Fixed an issue in PV Elite regarding center-to-center distance calculations for saddles on horizontal vessels. Previously, the software used an incorrect value of Ls in calculations on the Horizontal Vessel Analysis report when using Response Spectrum Analysis as the earthquake design code. The issue has been resolved and the correct value of Ls is used.
  • Fixed an issue in PV Elite & CodeCalc in which an incorrect pressure value was calculated for load case O4 when a differential pressure was specified for a fixed heat exchanger. The software now correctly calculates the pressure for Ps & Pt in the Detailed Results for Load Case O4 Corr ( + Th) section on the ASME TS Calc report. 
  • Fixed an issue in PV Elite in which the software used an incorrect pressure to determine the Sigma 5 stress for horizontal heat exchangers on saddle supports. Previously, the software considered the channel side pressure when calculating Sigma 5 calculations. The software now correctly considers the shell side pressure in Sigma 5 calculations on the Horizontal Vessel Analysis report.

Output Reports

  • Fixed an issue in PV Elite in which a warning message did not display on output reports when certain required values could not be calculated. Previously, the software did not display a warning message when the small end hub thickness could not be determined per UW-21 for Full Face Slip On flanges. Now, when the software cannot calculate the thickness, a warning message displays in the Weld Sizes for Slip on Nozzle Flanges per UW-21 section of the Nozzle Schedule report. 
  • Updated PV Elite to include a warning message when certain values of a cone’s small end are out of range. Previously, the software did not contain a warning when the Rs/tS values of the small end of a cone did not satisfy the requirements of section 4.3.11 of the ASME Section VIII Division II code. The software has been updated, and a warning message now displays in the Conical Section report when the Rs/tS values are out of range.

PV Elite and CodeCalc 2015, Hot Fix 1

The following list details fixes to PV Elite and CodeCalc (Version 17.00.00.0001), which may affect the numeric results:

  • Fixed an issue in PV Elite where the software incorrectly interpolated allowable stress values for materials in the metric material database. Previously, when you selected Use Metric ASME Material Database on the Configuration dialog, the software displayed an incorrect value for Allowable Stress, Operating of a metric material if you were changing the design internal pressure. The software now correctly calculates stress values for materials in the metric material database.  
  • The For ASME, Include Japanese Materials option was removed from the Default Value Settings tab of the Configuration dialog. 
  • Fixed an issue with creating a new tubesheet in PV Elite when using Windows 8 or Windows 8.1. Previously, when you selected Tubesheet Analysis to create a new tubesheet, the software stopped functioning. However, the software functioned as expected when you selected an existing tubesheet. You can now successfully create new tubesheets when using the Windows 8 or Windows 8.1 operating system.

  • Perform finite element analysis (FEA) on thick expansion joints in PV Elite using third-party Paulin Research Group software, You can perform FEA on expansion joints for ASME, TEMA, EN-13445, and PD 5500 tubesheets. You must have the NozzlePRO software installed before using this functionality. (CR-TX-10271, CR-TX-10468)
  • Enhanced PV Elite to allow you to define the dimensions of a stepped tubesheet on the Tubesheet Properties tab of the Heat Exchanger Tubesheet Input dialog Click Stepped Tubesheet and define the dimensions of the tubesheet in accordance with part UHX-10(b) of the ASME code in the Stepped Tubesheet Effective Diameter Calculation dialog box. The software calculates the minimum thickness of the tubesheet, and automatically adjusts the diameter based on the extension thickness. The software enables the Stepped Tubesheet option only when you select Tubesheet Extended as Flange on the Tubesheet Properties tab. 
  • Enhanced CodeCalc to allow you to define the dimensions of a stepped tubesheet by browsing in the Outside Diameter of Stepped Tubesheet on the Tubesheet Define the dimensions of the tubesheet in accordance with part UHX-10(b) of the ASME code in theStepped Tubesheet Effective Diameter Calculation dialog box. The software calculates the minimum thickness of the tubesheet, and automatically adjusts the diameter based on the extension thickness. The software enables the Outside Diameter of Stepped Tubesheet option only when you select Tubesheet Extended as Flange on the Tubesheet tab. 
  • Resolved an issue in PV Elite where the software displayed a torispherical head as a spherical Previously, when the value of the Inside Knuckle Radius fell below six percent of the value of the Crown Radius, the 3D view of the torispherical head displayed as a spherical head. The software now uses a new algorithm to plot a more accurate torispherical head for the 3D model. 

Calculations

  • Updated PV Elite to follow the DIN Standard for EN-13445 for torispherical and semi-ellipsoidal heads. According to DIN 28013, for torispherical heads, the crown radius should be 0.8 x OD (outside diameter) and the knuckle radius should be 0.154 x OD. According to DIN 28011, for semi-ellipsoidal heads, the knuckle radius should be 10 percent of the crown radius. Now, when you enter the outside diameter for one of the aforementioned heads, the software automatically calculates the crown radius and knuckle radius according to the code standard. 
  • In PV Elite, previously when you placed a nozzle at the location of a shell band, the software performed nozzle data calculations without considering the shell band Now, when you select the Is there a Shell Band? check box on the ASME Part UHX/EN-13445 Shell Band Data dialog box, the software considers the shell band thickness in the WRC and nozzle reinforcement thickness calculations. 
  • In PV Elite, previously when you added a saddle at the location of a shell band, the software performed saddle data calculations without considering the shell band Now, when you select the Is there a Shell Band? check box on the ASME Part UHX/EN-13445 Shell Band Data dialog box, the software considers the shell band thickness in the calculations in the Longitudinal Stress at Top of Shell at Support saddle calculations. 
  • Enhanced PV Elite to retain zoom settings in the Output Type CTRL + Scroll up/down to change the zoom settings of output reports. Previously, the software did not save zoom settings when you exited the Output Processor. Now, when viewing reports in the Output Processor, the software defaults the report view to your previous zoom settings.

Output Reports

  • Improved the PDF output reports that PV Elite generates to Report bookmarks display in the PDF based on the reports you select from theReport List on the Output Processor. Click a bookmark in the report to jump to that section of the report without having to scroll, similar to how you select a report from the Report List in the Output Processor. 
  • In PV Elite, previously when you when you added a carbon steel shell band that was thick enough to require post-weld heat treatment or impact testing, the software did not provide a warning message for post-weld heat treatment or an impact testing requirement during analysis and in the notes in the output Now, when you select the Is there a Shell Band? check box on the ASME Part UHX/EN-13445 Shell Band Data dialog box and set the thickness to require impact testing or post-weld heat treatment, the software displays a warning message during analysis and a warning on the ASME TS Calc : Case 1 Ope report
  • Updated PV Elite reports to include notes identifying the factors by which the software calculates the wind and seismic The Wind Load CalculationEarthquake Load Calculation, and Wind/Earthquake Shear, Bending reports include the respective load reduction factor for the load calculations. The reports also identify the scale factor entered in Global Scalar for WI loads or Global Scalar for EQ loadson the Load Cases tab.
  • Added a clarification to the ASME TS Calc: Tubesheet output report in PV Previously, for a heat exchanger with a simply supported tubesheet, the ASME TS Calc: Tubesheet report included a note that stated the minimum shell length that was required for a shell of a certain thickness. The report displays an additional note now that clarifies that, for vessels where calculations meet stress and thickness requirements, the first note is for information purposes only. (CR-TX 10603, CR-TX-10612)

Technical Changes

The following list details changes to PV Elite and CodeCalc (Version 17.00.00.000), which may affect the numeric results:

Calculation Updates
  • Fixed an issue in PV Elite regarding calculations for the bottom opening of conical When a vessel with a flared conical skirt had a larger stress at the top of the skirt than the bottom, and you selected Use and Allow Editing of Local Scalars in the Load Cases on the Load Cases tab, the software calculated a larger basering fillet weld size than was required on the Basering Calculations report forRequired Basering to Skirt Double Fillet Weld Size. The calculation for the moment at the bottom of the skirt has been optimized, resulting in a smaller basering fillet weld size. (TR-TX-11610)

Technical Changes

The following list details changes to PV Elite and CodeCalc (Version 16.00.01.000), which may affect the numeric results:

ASME Tubesheets

In the 2013 Edition of ASME VIII-1, Table UHX-8.1 did not include all eight load cases. Load case 4 is a design load case with full vacuum on both sides. The effective bolt load for load case 4 is 0, instead of what is shown in the ASME table. PV Elite use a value of 0 for the bolt load for this load case, which may reduce the required tubesheet thickness. This reduction occurs when vacuum pressures were entered, especially when the gasket has non-zero m and Y factors. When a nominal shell thickness is specified for the shell side of the exchanger, the software uses the value in the tubesheet calculations.

Flanges

For flanges that are subject to external pressures, when the flanges have a different internal and external temperature, PV Elite recalculates the flange and bolt allowables for the external temperature.

Exchangers with Thickened Shell Bands

With this version, the software now explicitly includes the extra weight of the shell band in the weight calculations. This enhancement changes all weight calculations, and affects all subsequent calculations involving weight. If you previously specified a mass to account for the extra shell band mass, remove this value.

EN-13445 Local Stress Analysis on Nozzles

With this version, EN-13445 local stress analysis on nozzles was revised. The graphs in this code standard (which also appear in PD 5500) determine stress concentration factors for applied forces and moments. Specifically, graphs 16.4-5, 16.4-6, 16.4-7, and 16.4-8 are in question. The curve labels are eb/ec = 0.0, 0.25, 1.0, and 0.5, respectively. Unfortunately, this configuration leads to multiple solutions for different values of eb/ec, which cannot be correct. PV Elite Development verified this using finite element analysis (FEA).

Additionally, the graphs that precede the graphs in question, such as 16.4-3, the curves are correctly labeled as 0.0, 0.25, 0.5, and 1.0, which leads to a unique solution for all eb/ec values in these ranges.

For the spherical graphs, PV Elite Development deduced that the curves for 1.0 and 0.5 in the standard must be mislabeled, and implemented the graphs differently than the standard in PV Elite calculations. Furthermore, this local stress analysis was taken from PD 5500, and the graphs in that standard appear to have the same issue.

Also, in the EN-13445 standard, the SCF is taken to be 1.0 at the edge of the pad, but this was not explicitly stated. Justification for this approach is found in PD 5500.

 

Technical Changes in PV Elite and CodeCalc 2014, SP2

The following list details changes to PV Elite and CodeCalc (Version 16.00.02), which may affect the numeric results:

Revised Calculations

 

  • Revised the calculation of the ASME Section VIII, Division 2 combined stress intensity to reflect the method outlined in the 2013 edition of the Example Problem Manual (PTB-3). For more information, see the ASME publication PTB-3-2013, see Example E4.3.6, Combined Loadings and Allowable Stresses.
  • Updated the allowable stress calculation for elements specified as flanges for some non-carbon steel materials, according to the latest EN 13445 code standards. For flanges, the software now uses Rp1.0/t / 1.5 for the allowable stress calculation. This change affects the calculation of stainless steel materials that are used as flanges when the elongation (A) is greater than or equal to 35 percent.

Revisions in PV Elite and CodeCalc 2014, SP2

The following revisions were made to PV Elite and CodeCalc software for the Version 2014, Service Pack 2 release:

Analysis Updates

  • Fixed an issue in CodeCalc where the software merged partition gasket values (specified on the Gasket Data tab for the flange) for an ASME Tubesheet, even if the flange did not have a partition gasket specified. The software no longer merges partition gasket values for a tubesheet when you clear the Is There a Partition Gasket? check box on the Gasket Data tab for the flange.
  • Resolved an issue in CodeCalc during shell and head analysis with jobs having an Analysis Type of API579, FFS (Fitness for Service). Previously, when you analyzed a file with a Flaw Type of General Metal Loss (Section 4) or Local Metal Loss (Section 5) (specified on the API 579 tab), and then changed the Flaw Type to Pitting (Section 6), CodeCalc closed out of the file and did not perform the re-analysis
  • Resolved an issue in CodeCalc with ASME Tubesheets where the software did not include the calculated Tubesheet Flanged Extension Thickness per UHX-9 in the Summary of Thickness Comparisons section of the analysis if the bolt load is transferred to the tubesheet. In this scenario, when you selected Is Boat Load Transferred to the Tubesheet? on the Tubesheet tab, the software calculated the values for the flanged extension thickness according to UHX-9 (using operating [hr_opr] and seating [hr_seat]). The software now displays the greater of these flanged extension thickness calculations in the Summary of Thickness Comparisons section of the analysis.
  • Resolved an issue in PV Elite when you transferred a bolt load to a tubesheet with a Tubesheet Type of (d) U-tube tubesheets, gasketed on both sides, the software did not display the Tubesheet Flanged Extension Thickness per UHX-9 results on the Summary of Thickness Comparisons section of the ASME TS Calc output report. PV Elite now displays the value in the Summary of Thickness Comparisons section of the report so that all of the relevant thicknesses appear in one final location.
  • Resolved an issue in CodeCalc and PV Elite when you transferred a bolt load to a tubesheet with a Tubesheet Type of (d) U-tube tubesheets, gasketed on both sides, the software did not display the Tubesheet Flanged Extension Thickness per UHX-9 results on the Summary of Thickness Comparisons section of the ASME TS Calc output report. PV Elite now displays the value in the Summary of Thickness Comparisons section of the report so that all of the relevant thicknesses appear in one final location. 
  • Fixed an issue where the CodeCalc software ceased to run when you changed an existing shell Type of Reinforcing Ring to Bar, changed the width and thickness of the ring, and then defined a new shell head component and set the Type of Reinforcing Ring to None. The software now successfully saves the shell head information. 
  • Updated the software to automatically choose the minimum or maximum value of the hub ratio (Xh), when the hub ratio value is less than or more than the dependent values for flanges, as specified in ASME Section VIII, Division 2. According to the 2013 edition, Table 4.16.5 specifies two equations for V. The choice of which equation to use depends on the Xh value (defined in Table 4.16.4). According to the standard, the value for Xh cannot be less than 0.1 or more than 2.0. If Xh is less than 0.1, the Flange Calculation output report includes a warning that the hub ratio (Xh) was less than 0.1 and the software set the value of Xh to 0.1.
  • Fixed an issue on the Vessel Jacket, Vapor/Distribution Belt Input dialog box when you entered a Half Apex Angle for a jacketed vessel of up to 60 degrees. In this situation, when you specified a Select Closure Type of Type (b-2), and you entered a Half Apex Angle of 30 degrees, the PV Elite software prompted you to enter a Half Apex Angle value between 0 and 30 degrees. The software no longer prompts you that you must enter a value between 0 and 30 degrees.

Material Updates

  • Resolved an issue where CodeCalc would stop running if you selected a material that was not in the database, and then changed the design temperature. In this version, CodeCalc prompts you to change the Allowable Stress values for the material, and the software continues to run. 
  • Resolved a usability issue in the CodeCalc software with entering a material. When you typed a material by keystroke and then hit ENTER, the software did not move the cursor to the next box. CodeCalc now moves the cursor to the next logical input automatically, so you can enter values quickly and then hit ENTER to move to the next box. 

Calculations

  • Fixed an issue in CodeCalc with nozzles that have reinforcing pads. When you cleared the Is there a reinforcing pad? check box on the Geometry tab for the nozzle component, the software removed all reinforcing pad data from the job. The software now sets the reinforcing pad data values to defaults appropriate for the nozzle data, as similar to how PV Elite functions.
  • Fixed an issue in nozzle calculations where changing the Shell Section Material to normalized or non-normalized (by selecting or clearing the Is the Material Normalized checkbox on the Shell/Head tab for the nozzle) caused CodeCalc to stop running. The software allows you to select or clear this checkbox for the shell material without issue now. 
  • Fixed issues with the formula substitutions in rectangular vessel calculations for Figure A2 and A6 types in the Figure Number for Type of Vessel box in CodeCalc.

Error Reports

  • Resolved an issue where the software displayed incorrect error message when you selected the Apply Seismic Loads to Vessel option to a horizontal vessel in CodeCalc. The error message stated that the Seismic Zone Identifier specified was not in the acceptable range, when the zone actually was in the applicable range. 

Output Reports

  • Resolved an issue with the Shear Stress check (Tau_ limit) formula in the ASME TS Calc output report for ASME tubesheets using metric units. Previously, when you analyzed a fixed tubesheet model in PV Elite or CodeCalc, the software displayed the Shear Stress check formula results in imperial units on the output report, even when the job was specified as metric. The software now displays the formula results for metric jobs in metric units.
  • Resolved an issue with a formula equation and substitution used in the UHX-13.5.8 ASME TS Calc output report for ASME tubesheets. UHX-13.5.8 Step 8 on the report referenced a formula from ASME Section VIII, Div.1, 2010 Edition 2011A. The report now correctly references the formula from ASME Section VIII, Div. 1, 2013 Edition.
  • Resolved an issue in CodeCalc involving the Bending Stress at the Shell section calculation in the output report for a rectangular vessel. The Bending Stress at the Shell section equation now cubes the t3/t1 expression in the result as per code standards. 
  • Updated the ASME U-1 and U-2 forms for vessel inspections to the latest revision released by the National Board. You can enter U-1 form information by selecting Tools > ASME Form Information. Then, you can analyze the job, review the report in the Output Professor, and submit the form to the National Board or appropriate authorities.
  • Fixed an issue with output report values in heat exchanger jobs. When the Hydrotest Type was specified as UG-100 (pneumatic), the software incorrectly included the hydro weight value in calculations and displayed it on the Element and Detail Weights report. In addition, the software displayed the Miscellaneous Weight on this report as zero percent, when the input value was 10 percent. The software now calculates and displays the correct values on the output report.
  • Fixed an issue where CodeCalc displayed NaN (Not a Number) and Infinity instead of populating the report with the correct input values. The software now displays the correct values on the WRC-297 Report.
  • Fixed an issue on the Heat Exchanger Tubesheet Input dialog box where the software disabled the Interface Pressures inputs on the Tube Data tab when you specified the Tubesheet Analysis Method as TEMA. PV Elite now lets you enter interface pressure information when you specify TEMA as the analysis method.
  • Resolved an issue with API-579 flaw/damage analysis where the software displayed a not-a-number (NaN) value on the Quick Calculation Results report for the Coefficient of Variation (COV) when there was only one thickness provided for the job. While the analysis is actually not viable when there are an insufficient number of data points given, the error message needed revision. When you press QuickCalc on the API-579 Flaw/Damage Input/Analysis dialog box, the software displays a more specific error message, “PV Elite could not perform the check for the Coefficient of Variation (COV) because you specified only one data point.”
  • Resolved an issue in output reporting where the software incorrectly calculate cylindrical component values, including the hoop stress intensity at the design pressure and any stresses induced on an element due to hydrotest pressure. PV Elite now calculates the hoop stress reported in the Internal Pressure Calculations output report by using the reverse of the formula used for determining the Required Thickness Due to Internal Pressure (tr).
  • Fixed an issue with the Saddle Force Q result caused by the center of gravity of nozzles on the Horizontal Vessel Analysis report. For nozzles attached to a Welded Flat head or Blind Attached flange elements on a symmetrical model, the Saddle Force Q was not the same value between the left and right saddle calculations. The output report now shows the Saddle Q Force as the same for the left and right saddles on a symmetrical model. 
  • Revised a calculation on the API-579 Calculations output report involving the conical and torispherical diameters. The software calculated the Inside Diameter of Shell (D) at a different value than the code standard. The calculation details appear in Step 6 in the Conical Shell section. The software now calculates this value in the same way as the code standard. 

Units of Measure

  • Fixed an issue with imported nozzle data in the WRC-107/537 and WRC-297 modules in CodeCalc. When you imported metric standard nominal and hub nozzle data from PV Elite (by browsing from the Import Nozzle Data from PV Elite box), the software displayed the Diameter column in the PV Elite Browser dialog box in inches, even when the nozzle file units were metric. The software now displays the diameter in the units of the imported nozzle file.
  • WRC 107/537 and WRC 297
  • Restored the ability to merge a shell or head component in the WRC 107/537 and the WRC 297 modules. This functionality was previously available in CodeCalc 2012. Select the ellipsis to the right of the Shell/Head Name box on the Vessel tab of the WRC 107/593 or WRC 297 module, and then select the shell or head in the Shell/Head selection dialog box to merge the properties.
