Ruining the design of water pipelines can lead to negative economic and environmental consequences. The usual scientific, technical and technological developments to ensure reliable corrosion-mechanical resistance and durability of water pipelines are not sufficiently systematic, so there is no need to report the reasons, minds and mechanisms of corrosion-mechanical servicing. Laboratory and experimental investigations were carried out in relation to the operation of structural steels on the structure and instead of schoolhouses. The causes and mechanisms of degradation of metal structures due to routine operation in chemically aggressive technological media were studied. X-ray diffraction studies have established that, with increasing service life of pipes, the surface metal balls adsorb a significant amount of gases. It manifests itself especially strongly in the area of corrosion defects (stains, pittings). During regular operation, the metal walls of the pipes are heavily flooded, which leads to a hardening, increased hardness and decreased ductility. There is a significant change in the mass fraction of cementite in the metal, which indicates a decrease in the value of the material and a decrease in its resistance to corrosion-mechanical damage. Such research is a pioneer in the corrosion-mechanical resistance of metal and its degradation during heavy use in the presence of significant pressures and in the immediate presence of aggressive media.
