Abstract
1. Способ монтажа обводной линии трубопровода, находящегося под давлением, включающийустановку на трубопровод муфтовых тройников,монтаж на тройники задвижек, снабженных фланцами,установку на фланцы задвижек устройств холодной вырезки отверстий,вырезку отверстий в трубопроводе посредством указанных устройств при открытых задвижках,закрытие задвижек,сброс избыточного давления из корпусов задвижек,демонтаж устройств вырезки,соединение фланцев задвижек обводной линией трубопровода,при этом используют устройство вырезки отверстий, содержащее корпус, размещенный в корпусе шпиндель, на конце которого установлен режущий инструмент в виде фрезы со сменными режущими пластинами, механизмы вращения и осевого перемещения шпинделя и средство герметизации шпинделя со стороны режущего инструмента.2. Способ по п.1, в котором после монтажа устройства для вырезки отверстий и перед вырезкой в корпус каждой задвижки подают негорючую жидкость для охлаждения режущего инструмента.3. Способ по п.2, в котором корпус задвижки заполняют жидкостью на ½ объема.4. Способ по п.1, в котором вырезку отверстий в трубопроводе осуществляют при скорости вращении режущего инструмента не более 3000 об/мин.1. A method of mounting a bypass line of a pressurized pipeline, including installing coupling tees on the pipeline, mounting valves with flanges on the tees, installing cold cut-out devices on the flanges of the valves, cutting holes in the pipeline using these devices with open valves, closing the valves, dumping excess pressure from the valve bodies, dismantling the cut-out devices, connecting the valve flanges by the bypass line of the pipeline, using a hole-cutting device, with holding body disposed in the spindle housing, which is mounted on the end of the cutting tool as a cutter with replaceable cutting inserts, mechanisms rotation and axial movement of the spindle and the spindle sealing means by cutting instrumenta.2. The method according to claim 1, in which after mounting the device for cutting holes and before cutting into the body of each valve, a non-combustible liquid is supplied to cool the cutting tool. The method according to claim 2, in which the valve body is filled with liquid by ½ volume. The method according to claim 1, in which the cutting of holes in the pipeline is carried out at a rotation speed of the cutting tool of not more than 3000 rpm
