摘要：

On the basis of the well-known theoretical concepts and some experimentally substantiated hypotheses, we propose a physicochemical model and establish mathematical relations for the description of the stress-corrosion fracture of pipe materials of underground oil-and-gas pipelines with regard for the intensification of this process by diffusion-moving hydrogen. We also quantitatively estimate the effect of hydrogenation on the rate of soil corrosion and residual service life of the pipes of oil-and-gas pipelines.
