FIELD: construction industry.
SUBSTANCE: fibrous construction, for example carbon fibres are put on pipe section subject to strengthening, polymeric material is applied to fibrous construction surface in order to perform saturation of fibrous construction when providing penetration of polymeric material inside fibrous construction to pipe section. Before polymeric material is introduced, components of external cover, for example coupling, casing, are installed around fibrous construction. Polymeric material saturates reinforcing material - fibrous construction and is hardened till strengthened polymeric composite is obtained.
EFFECT: invention allows restoring nominal pipeline pressure.
