Zusammenfassung:	construction and repair of pipelines without stopping product transport. SUBSTANCE: defective surface of pipeline is made ready for repairs; flaw cavities are filled with paste-like hardening material; adhesive is applied to pipeline surface to winding material, the latter is wound on pipeline defective area followed by hardening of adhesive. Rolled glass-fiber plastic pre-overlapped at least on one side by polyolefin adhesive-active film is used as winding material; adhesive used in said method has viscosity of maximum 1500 cP. EFFECT: improved post-repair reliability of pipeline. 2 cl
