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

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.

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

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.

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 )

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.

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.

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
