摘要: The comparative assessment strength and fracture of three API grade pipeline steels: X52; X70 X100 has been done for conditions hydrogenating. factors cathodic hydrogen charging, time exposition, concentration in metal applied load were taken into account. relationship between critical (failure) loading found. Also, the existence some concentration, which causes significant loss local resistance material, was shown.
