Study on the Safety Margin of Pressure Vessel Pit Defect Based on the Defect Failure Simulation Path

Abstract:

In order to obtain the level of security of the pressure vessel with pit defects, a safety evaluation simulation system bases on the failure paths of pit defects was used to find the level of dynamic security. The parallel method or radial method can not be used to get the real level of dynamic security of pit defects, but the distance along the failure path to the safety critical line, and a new way was provided in detail.
