STATIC AND DYNAMIC STRENGTH OF RING WELDING JOINTS OF PIPELINE ELEMENTS MADE OF CORROSION-RESISTANT STEELS OF DIFFERENT BRANDS

The main stages of obtaining annular welded joints of pipeline elements from various corrosion resistant stainless steels are considered. The characteristics of the static and dynamic strength of annular seams of pipeline assemblies with experimental cylindrical specimens under loading by internal pressure are determined

LOW-CYCLE FATIGUE OF THIN WALLED PIPES MANUFACTURED WITH ROTATIONAL ROLLING-OFF

The main results of experimental studies on the effect of deformation degree during rotational rolling-off with thinning of the wall of a single-seamed cylindrical shell on the maximum number of loading cycles before the failure of a welded joint are presented in the paper
