Analysis of Stresses in Pressure Vessels
and Tank Shells at Nozzle and Clip Connections Resulting from
External Loads
WERCO 107/297™ is a comprehensive software
package for calculating stresses in shells in accordance with
the guidelines set forth in the Welding Research Council Bulletins
107 & 297. The program eliminates the need for hours of
tedious hand calculations and manual cross referencing and
dramatically reduces the possibility of errors.
GENERAL FEATURES

Easy to use Data Entry Dialog screens |
|
Easy to understand HELP screens |
|
Extensive Data Checking |
|
Imperial and International units |
|

WERCO 107/297™ CAPABILITIES
|
Calculates stresses at eight points on the shell at the nozzle,
clip or lug intersection |
|
Automatically compares calculated maximum combined stress
intensity with the allowable stress value – automatically increases
reinforcing pad thickness until the calculated stress value
is found to be less than the allowed stress |
|
Determines worst combination of positive and negative loads
and then designs a reinforcing pad so that the calculated stress
is less than the allowed stress. |
WERCO 107/297™ APPLICATIONS
|
Provides an effective tool for evaluating the ability of a
nozzle to withstand the forces and moments applied by piping |
|
Provides an effective tool for evaluating the ability of a
clip to withstand the force and moment loads applied by piping,
structural members and equipment |
|
Provides an effective tool for evaluating the ability of a
lifting lug to withstand the forces and moments applied to it
at lift |
|
Provides technical compliance and documentation for regulatory
authorities |
|
Enables an engineer/designer to determine the reinforcement
required in spherical and cylindrical shell at the intersection
of a nozzle, a clip or a lifting lug. |
