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 the pipeline coupling eliminating the specified disadvantages of analogues and the prototype providing reduction of labor intensity of assemblage of couplings at repair of pipelines, and also improvement of operational reliability of the pipeline with damages of walls of pipes. Pipeline coupling includes two half-couplings made in the form of elastic band from composite material. Device is equipped with fixture, in the form of ledges with loop grips and recesses located opposite protrusions of joint tape, embedded elements, rectangular cross-section with rounded edges, which contain support at the ends, spacer elements.
EFFECT: simplified assembly, increased efficiency of non-metal repair couplings.
