Abstract. The paper deals with the innovative methods for monitoring the technical state of
pipelines in difficult conditions. Within the framework of the methodology of Risk Based Inspection, the approach is analyzed using the innovative magnetic tomography method, which offers the inclusion of
the registration of real mechanical stresses in the system for assessing the reliability of pipelines by the criterion of transition to the limit state based on the registration of the degree of stress concentration or excess of local loads.
Keywords: oil pipeline, gas pipeline, magnetic tomography method, stress-corrosion processes, Villary effect, corrosion, stress corrosion cracking, metal embrittlement, in-line inspection, pipeline
condition monitoring, stress-strain state, ferromagnetic material.

Pipeline is an engineering system of a lengthy network of seamless or welded-on pipes
designed for the delivery of commercial gas, oil or oil products from fields to consumers in the
domestic or global commodity market (refinery, gas processing plant, liquefied natural gas plant,
marine terminal and others).
The length of trunk pipelines in Russia is more than 250 thousand km, and gas pipelines
and gas pipelines-branches of PJSC Gazprom in Russia is 172.6 thousand km as of 01.01.2009.
According to the international consulting company KPMG, PJSC Transneft is the leader among
oil pipeline companies in terms of the volume of oil transportation – 478 and oil products – 33
million tons and the length of oil pipelines – 51.5 and oil product pipelines – 16.9 thousand km
as of 01.01.2018. Total length of field pipelines in Russia exceeds 0.35 million km.
Internal and external corrosion are the main causes of pipeline accidents. Internal
corrosion was the cause of about 15% of gas pipeline accidents over the past 30 years, according
to Pipeline and Hazardous Materials Safety Administration (PHMSA) database.
