Effects of Prestrain on the Tensional Function of X60 Pipeline Steel
It is impossible to keep pipelines free from defects in the manufacturing, installation and servicing processes. In this paper, pre-tension deformation was used to imitate the defects of the part of material and the effect of per-tension deformation to the tensional function of X60 pipeline steel was investigated by tension experiment. The results indicate that the per-tension deformation increased the σ5 and σb reduced the malleability of the X60 pipeline steel. With the pre-deformation increase, the ?/is increased but the σf is reduced obviously.
