A process of repair of defect sections of pipelines is in fact that defect section of pipe is cleaned with removal of corrosion products, one levels surface by means of putty, it is covered with glue, finally one levels surface of pipe with glass fiber mat, it is reinforced with banding with glass-fiber material soaked with polyether tar. At that preliminarily at both sides of defect section one installs two technological rings that are welded in perimeter to gas between those, one forms composite bandage, and to technological rings one connects by long angular seams metal frame that consists of several segments. Technical result is in decrease of longitudinal load to composite bandage.
