Abstract
A method for restoration of carrying capacity of linear and bended sections of acting pipeline consists in that at outside of pipe being repaired one installs metal shell made of couplings installed in step method, with filling under-coupling space with curing mass. For bended sections couplings are made similar to sections of pipelines being repaired, restricted with annular seams. On the sections one turns on wire on which couplings are assembled. Faces of adjoining couplings are welded to each other with annular seam. At bended sections with defect seam angle couplings are installed on technological rings. Between the faces of adjoining couplings in perimeter of pipe one installs metal insert with round cross section. To divide under-coupling space one uses thermo-shrinking band. The technical result is in repair of bended sections at minimal volume of under-coupling space, increase of accuracy of mounting due to optimization of air-gap for welded seam, prevention of loose of tightness of chamber separators of under-coupling space.
