WERCO - Version 107/297 -Calculating Stresses Comprehensive Software Package
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
- Support provided by experienced engineers
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.
