The problem of calculating the stress-strain state of a thick-walled pipeline subjected to the joint action of force load, temperature and corrosion wear is considered. The influence of temperature on the mechanical properties of the pipeline material, as well as on the rate of corrosion wear are taken into account. Such relations of material deformation model and corrosion wear model are used, which allowed to obtain an analytical solution. The analytical solution will allow to perform a timely and correct analysis of the stress state of a thick-walled pipeline, to determine the value of the ultimate pressure for a given pipe wall thickness, to determine the ultimate service life of the pipeline at known initial parameters, limit condition and corrosion wear regularities
Key words: thick-walled pipeline / temperature effect / corrosion wear / pipeline durability / analytical solution
