Claims (8)

1. Способ ремонта стального трубопровода, включающий подготовку ремонтируемой трубы, протяжку секций «чулка» через участки ремонтируемой трубы и соединение секций «чулка», отличающийся тем, что «чулок» выполнен жестким и представляет собой трубу, изготовленную из полимерного материала с памятью формы, при этом в процессе протяжки «чулок» перед вводом его в ремонтируемую трубу подвергают обжатию, а восстановление формы «чулка» происходит после его установки внутри ремонтируемой трубы.1. A method of repairing a steel pipeline, including preparing a repaired pipe, pulling the sections of the “stocking” through the sections of the repaired pipe and connecting the sections of the “stocking”, characterized in that the “stocking” is made rigid and is a pipe made of a polymer material with shape memory, while in the process of broaching the “stocking” before entering it into the repaired pipe, it is crimped, and the shape of the “stocking” is restored after it is installed inside the repaired pipe. 2. Способ по п.1, отличающийся тем, что в качестве материала «чулка» используют полиэтилен средней или высокой плотности.2. The method according to claim 1, characterized in that the medium or high density polyethylene is used as the “stocking” material. 3. Способ по п.1, отличающийся тем, что внешний диаметр «чулка» лежит в пределах между внешним и внутренним диаметрами ремонтируемой трубы.3. The method according to claim 1, characterized in that the outer diameter of the "stocking" lies between the outer and inner diameters of the pipe being repaired. 4. Способ по п.1, отличающийся тем, что степень обжатия «чулка» лежит в пределах от 0,95 до 0,85 его первоначального диаметра.4. The method according to claim 1, characterized in that the degree of compression of the "stocking" lies in the range from 0.95 to 0.85 of its initial diameter. 5. Способ по п.1, отличающийся тем, что внешняя поверхность «чулка» выполнена гладкой.5. The method according to claim 1, characterized in that the outer surface of the "stocking" is made smooth. 6. Способ по п.1, отличающийся тем, что внешняя поверхность «чулка» выполнена с продольными канавками.6. The method according to claim 1, characterized in that the outer surface of the "stocking" is made with longitudinal grooves. 7. Способ по п.1, отличающийся тем, что процесс подготовки ремонтируемой трубы включает очистку, калибровку и антикоррозионную обработку ее внутренней поверхности.7. The method according to claim 1, characterized in that the process of preparing the pipe being repaired includes cleaning, calibration and anticorrosion treatment of its inner surface. 8. Способ по п.1, отличающийся тем, что соединение секций «чулка» осуществляют сваркой его торцов.8. The method according to claim 1, characterized in that the connection of the sections of the "stocking" is carried out by welding of its ends.
