Механизм 3 изготовлени  рукава 4 выполнен из нагревател  5, системы 6 нагнетани  и пуансона 7 с матрицей 8 В кольцевом фланце 9, соединенном с матрицей 8, выполнены отверсти  10 IB низшей части матрица 8 имеет распи- i ракицийс  конус 11, переход щий в тру- бу 12, котора  устаноплена в трубопроводе о The drawing shows a device for: carrying out the proposed method; I 5, the injection system 6 and the punch 7 with the die 8. The annular flange 9 connected to the die 8 has holes 10 IB of the lower part of the die 8 which has a cone 11 which passes into the pipe 12 which is installed in the pipeline.

Полость трубопровода 2 сообщена через трубу 13 с полостью конуса 11 оThe cavity of the pipeline 2 is communicated through the pipe 13 with a cavity of a cone 11 about

Система 6 нагнетани  сообщена вы- соконапорной магистралью 14 с корпусом 15, а магистраль 16 - с полостью конуса 11 о В корпус 15 загружен полимер оThe injection system 6 is connected by a high-pressure line 14 to the body 15, and the line 16 is connected to a cone cavity 11 o. The body 15 is loaded with a polymer o

В трубопроводе 2 установлен пор- шень 17с Между рукавом 4 и поршнем 17 закачан клей„In the pipeline 2 a piston 17c is installed. Between the sleeve 4 and the piston 17 glue is pumped.

В корпусе 15 установлены катуш- ки 1.8 с намотанной на них проволокой 19 из протекторного сплава, Coils 1.8 are installed in the housing 15 with wire 19 made of a tread alloy wound on them;

Устройство работает следующим . образом,The device works as follows. in the way

Расплавленньй полимер через отверстие 10 за счет ,цавлени  рабочего агента, подаваемого в корпус 15 через высоконапорную магист аль 1А, поступает в кольцевой зазор между матрицей 8 и пуансоном 7 вместе с проволокой 19„ За счет рабочего агента, поступающего в корпус 11 че рез трубу 13, полимер охлаждаетс . Давление рабочего агента, подаваемого через магистраль 16, по лимер раст гиваетс  до стенок конуса 11, при этом толщина рукава принимает заданные размеры. На стенке конуса 11 рукав 4 совсем охлаждаетс  и твердеет вместе с проволоками 19, котоThe molten polymer through the hole 10 due to the formation of the working agent supplied to the housing 15 through the high-pressure master al 1A enters the annular gap between the matrix 8 and the punch 7 together with the wire 19 "Through the working agent entering the housing 11 through the pipe the polymer is cooled. The pressure of the working agent supplied through line 16 is stretched to the walls of the cone 11, and the thickness of the sleeve takes on given dimensions. On the wall of the cone 11, the sleeve 4 is completely cooled and hardens together with the wires 19, which

рые располагаютс  внутри рукава За счет рабочего агента, подаваемого в трубопровод 2 системой 1, рукав 4 через трубу 12 вытаскиваетс  в трубопровод 2 оare located inside the sleeve. Due to the working agent supplied to the pipeline 2 by the system 1, the sleeve 4 is pulled through the pipe 12 into the pipeline 2 o.

В трубопроводе 2 рукав 4 перемещаетс  по нему и поджимаетс  к смазанной клеем стенке трубопровода 2, Клей и поршень 17 перемещаютс  по трубопроводу 2 рукавом 4, После того , как рукав 4 уложен по трубопроводу 2, в нем повьппают давление и выдерживают трубопровод до полимеризации кле ,In the pipe 2, the sleeve 4 moves along it and presses to the wall of the pipe 2 greased with glue, the glue and the piston 17 move along the pipeline 2 with the sleeve 4.

They protect the pipeline with a length of 700 mm and a length of 300 m. They manufacture a sleeve of 700 mm and a length of 310 m from 1 mm thick PVC film. On the inner surface of the sleeve, sixteen 0-0 mm thick wires of alcine alloy of the following content are soldered, weight, hours,:

Рукав кле т на внутреннюю поверхность трубопровода проволоки к стенке .The sleeve is glued to the inner surface of the wire conduit against the wall.

После полимеризации кле  в трубопровод подают воду.After polymerization glue in the pipeline serves water.

От коррозии трубопровод защищаетс  слоем кле  и рукавом. Если рукав порветс  и нарушитс  слой кле , то вода заходит под пленку и начинает взаимодействовать с алюминиевой проволокой, котора  самораствор етс . При растворении алюмини  возникает электрический ток, который защищает трубопровод от коррозии. Растворенные продукты осаждаютс  на стенке трубопровода между рукавом . На стенке трубопровода образуетс  окисна  пленка, котора  предохран ет трубопровод от коррозии.The pipeline is protected from corrosion by a layer of glue and a sleeve. If the sleeve breaks and the adhesive layer is broken, water enters the film and begins to interact with aluminum wire, which self-dissolves. When aluminum dissolves, electric current occurs, which protects the pipeline from corrosion. Dissolved products are deposited on the pipe wall between the sleeve. An oxide film is formed on the pipe wall, which protects the pipeline from corrosion.

После нанесени  рукава он был ,порван в середине трубопровода. После года эксплуатации на стенке трубопровода обнаружено покрытие гр зно-серого цвета. Язв и наростов на стенке трубопровода не обнаружено .After applying the sleeve, it was torn in the middle of the pipeline. After a year of operation, a gray-gray coating was found on the pipeline wall. Ulcers and growths on the wall of the pipeline is not detected.

Предлагаемое изобретение позвол ет защгпцать действующие трубопроводы.The present invention allows for clamping existing pipelines.
