Residual Stress Profile in Tubular Components

CODEN: MPCACD

Abstract

The precise manufacturing of seamless steel pipes requires postprocess straightening treatments that lead to rather complex and not easily predictable residual stress fields. In this work, we combine blind hole drilling (BHD) and X-ray diffraction (XRD) techniques to determine the most relevant component, the circumferential (hoop) stress: BHD is used on the outer surface of the steel pipe and XRD is used on the inside; the results from both techniques are combined with a progressive layer removal procedure to determine the stress profile across the pipe wall.
