3.11.4. Calculation as per WRC 537/107(297)

In calculation results as per WRC 537/107(297) the following data is displayed: calculations of stresses under influence of internal pressure as per [10] and table of stresses in the shell (head) and branch pipe as per [8, 9, 11] with conclusions on the fulfilment of the strength conditions in accordance with selected normative document for strength estimation. For more detailed information on calculation methods see section "Calculation as per WRC 537/107(297)".

Calculations with WRC 537/107(297) are possible only for radial nozzles without pads of cylindrical shell, elliptic and spherical heads.
