The calculation results for both variants are shown in Fig. 3 and Fig. 4 and are summarized in Table 1. Analyzing the presented results, we may see that corrosion has influence of the residual wall thickness, i.e. it would be around 13% lesser then in the base case (without corrosion). Thus, corrosion accounting leads to ~50 mm wall thickness, it is still enough to carry the possible over pressure loadings.
