Abstract: The introduction of new technologies for diagnosing underground metal pipelines with dangerous surface defects is a practically important task. That is why studies aimed at improving the methods of assessing the quality of deformed metal pipelines and structural elements are necessary and relevant. The evaluation of the effectiveness of engineering and technological solutions for oil and gas enterprises needs improvement. In this context, an important task is to solve the problem of quality control (including durability) of gas and oil transportation systems and the improvement of appropriate metrological support. Based on surface physics and fracture mechanics, development of a methodological approach to assessing the quality and resource of underground metal pipelines (UMP) of oil and gas enterprises, taking into account the constructions strength, corrosion fatigue, parameters of corrosion protection and metrological support. Results of processing of normative documents and scientific works in the field of gas transportation enterprises, as well as methods of surface physics, mechanics of deformed solid body, fracture mechanics, qualimetry regarding the system “pipeline (UMP) – coating”. A new criterion for the strength of the surface of a metal underground pipe is proposed, which characterizes the peculiarities of bond fractures (adhesion) between the coating and the metal. Using the criterion of the strength of a metal tube with a defect in the electrolyte, the dependence of the critical internal pressure of the gas pipeline (UMP) on the geometric and energy (elastic and plastic) parameters of the metal, as well as the current of the anodic dissolution, which characterizes the features of the crack propagation at the bottom of the corrosion cavern. On the basis of surface physics and fracture mechanics obtained, a methodology for evaluating the quality of underground metal pipelines of oil and gas enterprises was developed to determine their resource, taking into account strength, corrosion fatigue, parameters of corrosion protection and metrological support.
