3. DESCRIPTION OF PROBLEM OR FUNCTION

FLANGE-ORNL        calculates
appropriate loads,  stresses, and  displacements for  the flanges,
bolts,  and  gaskets that  comprise  a  flanged piping  joint  for
internal  pressure or  moment  loading  on the  pipe,  temperature
difference between the flange hub and ring, and variations in bolt
load  that result  from  pressure,  hub-ring temperature  gradient
and/or bolt-ring temperature differences.   Flanges considered may
be tapered-hub, straight or blind.

4. METHOD OF SOLUTION

The  solution   is  based   on  discontinuity
analysis and the theory of plates and shells.

6. TYPICAL RUNNING TIME

Program compilation  required 19.4  seconds
CPU  time.  Total  execution time  for six  sample flanged  joints
required 1.15 seconds.

7. UNUSUAL FEATURES OF THE PROGRAM

FLANGE-ORNL has a  unique set of
user-controlled options  which allow  for calculating  ASME boiler
and pressure  vessel code  design criteria  and/or more  extensive
stress analysis, and also for  specifying various different flange
design  combinations for  the  joint.   In addition,  the  program
calculates  values for  various  ASME  code variables  that  would
otherwise have  to be extracted manually  from curves and  used as
input.
