Способ может быть использован для защиты внутренней поверхности трубопроводов от коррозии. Изобретение обеспечивает повышение эффективности защиты путем увеличения срока службы и коррозионной стойкости покрытия в среде сероводородсодержащих вод. Для этого в качестве цементного покрытия используют цементную композицию со следующим соотношением компонентов мас.%: портландцемент - 63,3 - 74,6; асбест - 1,4 - 3,3; вода - 23,1 - 33,4; причем для увеличения протяженности покрываемого участка трубопровода покрытие внутренней поверхности трубопровода осуществляют пневмопоршневым методом. Твердение покрытия происходит в среде углекислого газа.The method can be used to protect the internal surface of pipelines from corrosion. The invention provides improved protection by increasing the service life and corrosion resistance of the coating in the environment of hydrogen sulfide-containing waters. To do this, as a cement coating using a cement composition with the following ratio of components, wt.%: Portland cement - 63.3 - 74.6; asbestos - 1.4 - 3.3; water - 23.1 - 33.4; moreover, in order to increase the length of the pipeline section to be covered, the inner surface of the pipeline is coated by the pneumatic piston method. Hardening of the coating occurs in an environment of carbon dioxide.
