PV Elite 2011 Enhancements

Significant Code updates

Heat Exchanger Enhancements

Internationalization

Productivity Enhancements

Additional User requests

4/23

1/1/2011

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

Heres how to set it

ASME Division 1 Code Updates

4


5/23

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 Youngs 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.


9/23

1/1/2011

Elastic-Plastic Analysis for Floating Exchangers

Shell

Allow small plastic yielding, allowable isapproximately 3*S

after plastic iteration

But, Tubesheet maybecome thicker

12

Very useful when tubesheet is ok but junction is overstressed.

( for Pressure cases )


10/23

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.


11/23

1/1/2011

Option to use Operating Temperatures

Can use Operating temperature instead of Design temperature.

Allowable stresses, Yield strengths and Youngs modulus at operating temperatures.

Operating metal temperatures are typically lowerthan the design temperatures.

14

Very useful for removing the overstress problems in the Thermal cases.


12/23

1/1/2011

Fixed and Floating Tubesheet Exchanger Analysis

Floating head and floating head flange analysis

Expanded EN HX. Functionality

15


13/23

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


14/23

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 notper some inspectors

Solution : New Metric database

It will be possible to choose between

native Metric database

or Imperial to Metric database.

To select one

Productivity Enhancements

19

Numerous Productivity Enhancements

Conventional Jacketed vessel

Vapor/Distribution Belts

Datum line customization

New Nozzle stress check for piping loads


17/23

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

Adding a Jacket or Vapor Belt

Adding a Jacket

Jacket can span multiple

Shell courses.

Only on cylinders for now.

Vapor/Distribution Belt

21


19/23

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

Datum Line Entry Options

User defined Work Flow

Allows the user to set the datum line in a way that best fitstheir work methods.

PV Elite will remember this setting from one model to

the next until these settings are altered. 23
