FIELD: construction.
SUBSTANCE: pipeline defect section is cleaned from corrosion products, surface is leveled with the help of putty, pasted with glue, pipeline surface is finally leveled by means of glass fibre mat. On both sides of defect section there are two technological rings installed, which are welded along perimetre in gap between them, and defect section of pipeline is reinforced with band from glass fibre material, impregnated with polyether resin. Thickness of composite band layer is equal to thickness of technological rings wall. Metal frame made of several segments is connected to technological rings by means of longitudinal angular seams.
EFFECT: improved efficiency of method.
