各位 ASME B&PVC 设计师， 早上好，相信在使用PVElite 2014 的过程中，各位已经检测到有更新了，这次就为大家带来了 Service Pack 1 for PVElite 2014 ！
以下是官方更新说明：
New stuff :
Template Functionality Improvements
Added a From Project Template option from the Home>New menu. (PV Elite)
Added a configuration setting to specify a folder location for project templates.
Added the ability to apply a template to multiple files at the same time.
Analysis Updates
Added functionality to skip the SCF method when you specify a Pressure Area method in PD 5500 analysis jobs.
Enhanced to add a single decimal place stress print out for Metric units in WRC 107 analysis jobs.
ASME Code-Related Enhancements
Enhanced reporting to now support printing out Material Stress Ratios used in Hydrotest Pressure calculations.
Updated the software to calculate Section VIII, Div. 2 Hydrotest Pressures for Exchangers.
Updated the software to calculate flange weld sizes (for slip-on flanges).
Activated CodeCase 2286 for heat exchanger tubes.
Unit of Measure Changes
Added the ability to select Metric units for Standard Bar Stiffeners.
Added a configuration setting to convert jobs with Metric input to Imperial units on output/reports.
Content Changes
Added Square Box tubing to the Europe database.
User Interface Enhancements
Added a new Icon Size setting for medium icons from the PV Elite main menu options.
Reduced the size of the Flange Dialog box to support lower resolution hardware.
Added a link to the Intergraph Smart Support website from the File>Help menu. (PV Elite & CodeCalc)
Enhanced the Design option in the Flange Dialog box.
Added a More Commands... option to the Customize Quick Access toolbar. (CodeCalc)
Added an option to Import Nozzle Data from PV Elite (in .pvdb format) in the WRC107/537/297/PD 5500 modules. (CodeCalc)
Updated the software to set the focus back to the input fields (grid) when the temperature value changes. (CodeCalc)
Included a Merge TEMA Tubesheet option in the ASME Tubesheet module. (CodeCalc)
Enhanced the Specific Gravity option so that you can now use the input to specify liquid density in the Horizontal Vessels module. (CodeCalc)
Technical Changes in PV Elite and CodeCalc 2014, SP1
The following list details changes to PV Elite and CodeCalc (Version 16.00.01), 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.
