PV Elite 2011 Enhancements
Significant Code updates
Heat Exchanger Enhancements
Internationalization
Productivity Enhancements
Additional User requests

Appendix 1-10 for nozzles
Alternate (to UG-37) procedure for
nozzles
Can provide a more economicaldesign
Earlier only for “Large” nozzles
Now for all nozzles on
cylinders or cones
Here‟s how to set it
ASME Division 1 Code Updates
4
1/1/2011
ASME Division 1 Code Updates
5
Flanges – bolt space correction factor (BSC)
To limit leakage between bolts
(in circumferential direction)
Penalty factor which increases flange moments
Rigidity Index calculation updated for the BSC
Min. neck thickness for Manway/Access openings
• Additional requirements for the 2010 edition
• Can increase the manway thickness, consider force/moment
• typically less severe than a process nozzle.

Other Code Changes
Section II Part D Material properties
– Allowable stress, Yield strength and Young‟s Modulus etc. updated
ASME Division 2 changes
– Conical transition
– Lots of formulae/table changes
EN13445 2009 Update -
– welded flat heads
– nozzles
– tubesheet flanged extensions

Heat Exchanger Enhancements
Numerous Enhancements for exchanger analysis
Simply Supported design option
Elastic-Plastic for floating exchangers
Tubesheets as „line of support‟ for external pressure
Operating temperatures instead of design temperatures
Implementation of EN Fixed and floating tubesheets
7
1/1/2011 10
Simply Supported modeling
Increase allowable from 1.5 * S
to 3* S (approx)
But, Tubesheet may
become thicker
10
Available for
ASME U-tube
ASME Fixed
ASME Floating
For Pressure cases
Very useful when tubesheet is ok but junction is overstressed.
1/1/2011
Elastic-Plastic Analysis for Floating Exchangers
Shell
Allow small plastic yielding, allowable is
approximately 3*S
after plastic iteration
But, Tubesheet may
become thicker
12
Very useful when tubesheet is ok but junction is overstressed.
( for Pressure cases )
1/1/2011
Vacuum Calculations
Tubesheet as a Support point
13
Previously, Design length LNow, smaller L => more economical design
Old: L = 5089 mm, tre = 7.9 mm
New: L = 3655 mm, tre = 7.3 mm
Useful for vacuum case. Reduced required thickness, may Eliminate rings.
1/1/2011
Option to use Operating Temperatures
Can use Operating temperature instead of Design temperature.
Allowable stresses, Yield strengths and Young‟s modulus at operating temperatures.
Operating metal temperatures are typically lower than the design temperatures.
14
Very useful for removing the overstress problems in the Thermal cases.
1/1/2011
Fixed and Floating Tubesheet Exchanger Analysis
Floating head and floating head flange analysis
Expanded EN HX. Functionality
15
1/1/2011
Internationalization
Continued support for world-wide users
“Metric” Material Database (VIII-1, VIII-2)
2009 IBC Update for Wind & Seismic
Costa Rican Seismic standard added
Updated Mexican Seismic Code standard
16
1/1/2011
New “Metric” Material Database
Imperial Internal Database
Converted from Imperial to user units 20,000 psi = 137.90 MPa v/s 138 MPa
Difference is insignificant
Acceptable per ASME Div. 1 GG-1
But not per some inspectors
Solution : New “Metric” database
It will be possible to choose between
native “Metric” database
or
Imperial to Metric database.
To select one

PV Elite 2011- Globalization
IBC 2009 Wind & Seismic
Same as IBC 2006
Costa Rican Seismic Code
Implemented for vessels and Exchangers
Help screens in English and Spanish.
Mexican Seismic Code Update
Updated to 2008 version
1993 version also available.
Help screens in English and Spanish.

Productivity Enhancements
19
Numerous Productivity Enhancements
Conventional Jacketed vessel
Vapor/Distribution Belts
Datum line customization
New Nozzle stress check for piping loads
1/1/2011
Jacket or Vapor/Distribution Belt
Integrated modeling
Internal pressure, External weight,
Wind, Seismic, CG, MAWP, …
Nozzle on Jacket
Or
Nozzle through jacket
Can choose between vapor belt or jacket
Closure bar Analysis
Can have multiple Jackets
On Screen Results
20
1/1/2011
Adding a Jacket or Vapor Belt
Adding a Jacket
Jacket can span multiple
Shell courses.
Only on cylinders for now.
Vapor/Distribution Belt
21
1/1/2011
No pressure Differential in a vapor/distribution belt so the external
pressure on the inner vessel segment is zero
A conventional Jacket versus Vapor/Distribution Belt
22
1/1/2011
Datum Line Entry Options
User defined Work Flow
Allows the user to set the datum line in a way that best fits
their work methods.
PV Elite will „remember‟ this setting from one model to
the next until these settings are altered. 23
1/1/2011
Nozzle Stress Check for External Loads
WRC 107 computes stresses in shell
Nozzle stress check using B31.3
