Abstract This article covers the issue of determination of strength and resource of long-term operated oil pipelines and oil product lines. Justification of strength and resource of long-term operated pipelines and oil product lines is based on the results of technical diagnostics and verification calculations. Methods for technical diagnostics and monitoring of oil pipeline and oil product line condition, calculation expressions and its parameters for verification calculation are presented, as well as decisions on further oil pipeline and oil product line operation, based on the results. © 2022 The Authors.

Keywords: oil pipeline, strength, resource, verification calculation, technical diagnostics, monitoring. 1. Problem Definition Oil and petroleum products trunk pipelines in Russia have great length (≈67 thousand km), are operated in different regions and climatic zones (Siberia, Arctic, Caucasus, European part) and under different conditions (under temperatures t from - 600С to +450С), and geological construction settings (above ground, underground, underwater, etc.) (Fig. 1). Development of status, strength and operating life diagnostics and monitoring methods for continuously operating oil trunk pipelines N.A. Makhutov, D.A. Neganov, E.P.Studenov, N.E.
