1. Способ покрытия внутренней поверхности трубопровода, заключающийся в введении в него комбинированного рукава из композита на основе пропитанного полимерным связующим волокнистого материала с наружным пленочным покрытием, закреплении конца комбинированного рукава на трубопроводе, выворачивании его и прижатии к стенке трубопровода под действием давления жидкой среды и последующей полимеризации, отличающийся тем, что перед введением комбинированного рукава в трубопровод в последнем размещают вспомогательный рукав из термопластичной пленки и в последний вводят комбинированный рукав.1. The method of coating the inner surface of the pipeline, which consists in introducing into it a combined sleeve made of a composite based on a fiber-impregnated polymer binder with an outer film coating, fixing the end of the combined sleeve on the pipeline, turning it off and pressing it against the pipeline wall under the influence of liquid pressure and subsequent polymerization, characterized in that before the introduction of the combined sleeve into the pipeline in the last place an auxiliary sleeve of thermoplastic second film and the last administered a combined sleeve. 2. Способ по п. 1, отличающийся тем, что вспомогательный рукав размещают в трубопроводе выворотом. 2. The method according to p. 1, characterized in that the auxiliary sleeve is placed in the pipeline by eversion. 3. Способ по пп. 1 и 2, отличающийся тем, что выворот вспомогательного рукава осуществляют действием сжатого воздуха под давлением 0,1 oC 0,5 ати.3. The method according to PP. 1 and 2, characterized in that the eversion of the auxiliary sleeve is carried out by the action of compressed air under a pressure of 0.1 o C 0.5 ati. 4. Способ по пп. 1 - 3, отличающийся тем, что полимеризацию комбинированного рукава осуществляют в замкнутом объеме, образованном вспомогательным рукавом и наружным пленочным покрытием волокнистого материала. 4. The method according to PP. 1 to 3, characterized in that the polymerization of the combined sleeve is carried out in a closed volume formed by the auxiliary sleeve and the outer film coating of the fibrous material.
