Two full-scale specimens with recesses in the form of a semi-ellipsoid and cylinder were tested to check the offered method for calculation of residual life of pipelines allowing for the surface defects. The above recesses stimulated surface corrosion damages under cycle loading by internal pressure. The results obtained proved adequacy of the developed method for estimation of residual life of pipelines comprising corrosion damages.
