| Abstract: | This paper analyzes the effect of the bending angle of the transverse tensile specimens for line pipe body on the testing value of yield strength. It expounds theoretically that such bending will decrease yield strength. It also proposes some stipulations for flattening of the transverse specimens for pipe body included in rel-ative standards. |
