Abstract

The fracture strength and the sensitivity to delayed fracture of the pipes in oil-trunk pipelines that are made of ferritic–bainitic and bainitic steels are studied. The results of modeling of the delayed brittle fracture of pipe steel during a simultaneous action of mechanical stresses and a corrosive medium are presented.
