 ASME Division 1 Code Updates  Appendix 1-10 for nozzles 

 Alternate (to UG-37) procedure for nozzles

economical



Can provide a more design



Earlier only for “Large” nozzles



Now for all nozzles on cylinders or cones



Here‟s how to set it

 ASME Division 1 Code Updates 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

1/1/2011

severe than a process nozzle.

5

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 1/1/2011

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

1/1/2011

7

Simply Supported modeling But, Tubesheet may become thicker

Increase allowable from 1.5 * S to 3* S (approx)

 Available for 

 ASME U-tube



 ASME Fixed



 ASME Floating

For Pressure cases

Very useful 1/1/2011

when tubesheet is

ok but junction is overstressed. 10

Elastic-Plastic Analysis for Floating Exchangers But, Tubesheet may become thicker

Allow small plastic yielding, allowable is approximately 3*S

Shell after plastic iteration

Very useful

when tubesheet is

ok but junction is overstressed.

( for Pressure cases ) 1/1/2011

12

Tubesheet as a Support point 

Vacuum Calculations

Previously, Design length Now,Lsmaller 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

13

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

Very useful

1/1/2011

lower than the design temperatures.

for removing the overstress problems in the Thermal cases.

14

Expanded EN HX. Functionality 

Fixed and Floating Tubesheet Exchanger Analysis



Floating head and floating head flange analysis

1/1/2011

15

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

1/1/2011

16

New “Metric” Material Database 

Imperial Internal Database



Converted from Imperial to user units



Difference is

 



20,000 psi = 137.90 MPa v/s 138 MPa

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.
