Measurement and Analysis of Residual Stresses in N80 Steel Pipe
It was found that both of longitudinal residual stresses and circumferential residual stresses in the same position of undeformed N80 steel pipe and deformed N80 steel pipe were not of uniformity in viewpoint of measuring results by section method. The results showed that the main deformation reason was high residual stress and its asymmetrical distribution.
