How is strength calculation done?

Thread Content

May I ask? The strength calculation for pressure pipelines is carried out using standard formulas, while stress analysis involves evaluating the loads from supports, hangers, and dynamic and static equipment; it does not involve strength calculations. The strength calculation for pressure vessels designed in accordance with GB150 is carried out using standard formulas, followed by stress analysis of dynamic and static loads; strength calculation itself is not involved ； For pressure vessels designed in accordance with GB4732, the strength calculation should be carried out through stress analysis, and stress analysis is also required for both static and dynamic loads. Simply put, it’s not understood: the strength calculation for pressure pipelines is carried out based on prescribed design rules, and it has nothing to do with stress analysis. The strength calculation for pressure vessels according to GB150 is also done using prescribed design rules, without any involvement of stress analysis. In contrast, the strength calculation for pressure vessels per GB4732 is based on stress analysis. Is that correct?
