Abstract
Способ ремонта регионального газопровода, изготовленного с подкладными кольцами, заключающийся в вырезке сварного стыка с подкладным кольцом, разделке кромок, «подтягивании» близлежащей трубы и сварке нового сварного стыка, отличающийся тем, что ширину вырезаемой катушки с каждой стороны от оси стыка ограничивают шириной, включающей половину ширины подкладного кольца с добавлением погрешности изготовления и установки, в сумме составляющих 30% ширины подкладного кольца, плюс 0,6 толщины стенки трубы со стороны реза.A method of repairing a regional gas pipeline made with washer rings, which consists in cutting a welded joint with a washer ring, cutting edges, “pulling” a nearby pipe and welding a new welded joint, characterized in that the width of the cut coil on each side of the joint axis is limited by a width including half the width of the washer ring with the addition of manufacturing and installation errors, amounting to 30% of the width of the washer ring, plus 0.6 of the pipe wall thickness on the cut side.
