ASME VIII-1, paragraphs UG-80 and UG-81 specify the out-of-roundness tolerances that must be maintained during pressure vessel fabrication. COMPRESS automatically provides the UG-80 and UG-81 permissible out-of-roundness tolerances needed to conform to these forming requirements.
COMPRESS conveniently produces an out-of-roundness summary report that lists all component maximum deviations and chord lengths. In addition, detailed UG-80 and UG-29 calculations are provided. They can be easily found in each of the individual formed component reports.
