Abstract
Considered are characteristics of pipeline steels and their welded joints, determining fracture resistance in the zone of detected defects. Attention is focused on corrosion thinning defects, as well as development of corrosion cracks. Proceeding from analysis of the publications and authors’ investigations, recommendations are given on quantitative values of the above characteristics under static loading on main pipeline.
Keywords: soil corrosion rate, «uniform» surface corrosion, pitting, groove-like defects, corrosion cracks, probability descriptions, risk of failure
