The program contains different moduli for the calculation of cylindrical shells, domend ends, opening reinforcements, flanges, flat covers, tubesheets, etc., together with an extensive material database containing the most important, DIN and EN materials listed in the W-sheets of AD 2000. The evaluation of stresses due to supports in accordance with S3/0 to S3/5 has also been provided. Specific program moduli also allow the simplified fatigue assessment in accordance with AD S1 and the detailed fatigue assessment (after a DBA calculation) in accordance with S1. The calculation of stresses due to nozzle loads according to S3/6 is also an option that can be added to the software. As in all the other Sant’Ambrogio packages, the user may purchase a licence only for the moduli that he will actually use. The calculation of the test pressure required by the PED is also possible.
