Safety Balance

▣ Classification of Piping System StressesPrimary StressStress induced by forces and moments applied internally and externally to the piping system, including bending stress from internal pressure, self-weight, wind, and other factors, as well as torsional stress.The safety of primary stress is evaluated by comparing it with the allowable stress of the piping material.Secondary StressStress caus..

▣ Piping Stress AnalysisNumerically verifies the design safety of piping systems, ensuring compliance with design codes and regulations, and determines whether the layout, support locations, types, and design requirements are met.Demonstrates numerically whether the system can be safely used within the allowable stress range under various loading conditions, as required by design specifications ..

Piping Stress Analysis OverviewThe purpose of piping stress analysis is to numerically verify the design safety of piping systems, ensuring compliance with design regulations and that the layout, support positions, types, and design requirements are met. It involves demonstrating numerically whether the system remains within allowable stress ranges under various load conditions specified in the ..
