Title:
ALLOWABLE STRESS CALCULATION DEVICE, ALLOWABLE STRESS CALCULATION METHOD, AND ALLOWABLE STRESS CALCULATION PROGRAM
Document Type and Number:
Japanese Patent JP2023178730
Kind Code:
A
Abstract:
To easily calculate an allowable stress for a piping member in which a thickness reduction with corrosion increases with the lapse of time.SOLUTION: In an allowable stress calculation device of an embodiment of the present invention, a load stress calculation unit calculates a load stress applied to a piping member when flowing a fluid in the piping member under a specific condition set by a condition setting unit, using the amount of thickness reduction calculated by a thickness reduction amount calculation unit. A creep rupture life calculation unit calculates a creep rupture life that is a period of time necessary for the piping member to cause a creep rupture when flowing the fluid flow in the piping member under the specific condition set by the condition setting unit, using the load stress calculated by the load stress calculation unit. An allowable stress calculation unit calculates an allowable stress based on the load stress calculated by the load stress calculation unit.SELECTED DRAWING: Figure 1
