Rapid Method for Determining the Distribution of Residual Stresses in Pipes

CODEN: MPCACD

Abstract

This paper describes the method of longitudinal residual stress measurement on inner and outer pipe surface layers, which is used for calculation of the distribution of all residual stresses over the wall thickness. The method proposed is applicable in cases of stresses that are opposite in sign and exist inside and outside the pipe. Moreover, in accordance with the hypothesis of a parabolic circumferential and longitudinal distribution of residual stresses, this paper proposes the calculation method of stress distribution by measured ultimate stresses of the same sign inside and outside the pipe. The method is suitable for use in the express laboratory of a workshop that produces cold-formed seamless pipes.
