The efficiency of the numerical-analytic approach to the evaluation of the kinetics and changes in the shapes of corrosion fatigue cracklike defects in the course of their propagation in the wall of the pipeline is experimentally demonstrated. An exp

We propose a numerical-experimental procedure for the evaluation of the possibility of safe operation and the risk of failures oil and gas pipelines after long-term operation with regard for the influence of the potential development of in-service de

We analyze general regularities of degradation of the mechanical and corrosion-mechanical properties of steels of oil and gas main pipelines and oil storage reservoirs after 28–40 years of operation. The transported oil product not only causes corr

We study the susceptibility of a welded joint of 17G1S steel to hydrogen embrittlement depending on the sequence of application of hydrogenation and loading. The highly plastic welded joint is susceptible to hydrogen embrittlement under rapid active

It is established that the most active corrosion components in gas-water-oil environment are hydrogen sulfide, carbon dioxide, oxygen, and mineral salts (especially chlorides). The main types of corrosion fracture of the metalware of oil and gas obje

We study the joint effect of hydrogenation and plastic predeformation of 40KhN steel of drill strings after heat treatment on its crack resistance under static and cyclic loads. In the nonhydrogenated state, plastic predeformation of steel only sligh
