FIELD: transportation.
SUBSTANCE: invention relates to pipeline transport and can be used for repair of steel pipelines transporting liquid or gaseous media under pressure. Purpose of the invention is creation of a coupling for repair of the pipeline excluding the specified lacks of analogues and the prototype providing improvement of operational reliability of the pipeline with the repaired coupling by damages of walls of pipes. Pipe repair coupling consists of two half-couplings joined to each other and made in the form of elastic bands from composite material. Tapes at the ends are equipped with embedded elements for connection of coupling tension assemblies, made in the form of plates with thickness not exceeding thickness of half-couplings, having on the side surface a closed along the perimeter of the embedded element slot for conducting threads of composite material when making half-couplings.
EFFECT: technical result of invention is reduction of overall dimensions and metal consumption of coupling tightening assembly.
