| Abstract: | The article analyzes derivations of the equations for calculating the wall thickness of the internal pressure cylinder in terms of national and international standards according to their different intensity theory and design principles. It raises questions to applicability of some equations by comparison and error analysis. Finally, the author proposes to make the national standards of shell design strength with applicable for both international standards and national situations. |
