For assessing reliability of a pressure piping containing defects, it is necessary to know the calculation method and the distributions of flow stress of material. In this paper, the ten sile experiments of material and fracture experiments of 20# carbon steel pipes were carried out.The experimental results were analyzed and compared with the numerical results, it can be concluded that the flow stress should be calculated as follow: (σy+σu) /2, and the flow stress is well fitted for log-normal distribution...
