Claims (11)

1. Способ соединения двух армированных труб из термопласта швом, полученным с помощью стыковой сварки плавлением, причем каждая труба имеет внутреннюю и наружную поверхности, а стенка трубы простирается от внутренней поверхности внутренней трубы до наружной поверхности наружного слоя при наличии одного или нескольких слоев армирующих волокон, располагающихся во внешней половине толщины трубы; концевые участки труб нагревают, прижимая их к помещенной между ними нагревательной пластине, так что термопласт на концах плавится, и после удаления нагревательной пластины торцевые поверхности прижимают друг к другу, вытесняя расплавленный материал торцов и вызывая течение термопласта наружу и внутрь с образованием внутреннего и наружного валиков, после чего трубам дают остыть, не допуская при этом разъединяющего их смещения в осевом направлении; один или каждый армирующий слой полностью или частично вытесняется вместе с перетекающим материалом наружу в процессе упомянутой высадки, так что в сварном шве образуется слой термопласта между слоем или слоями армирующих волокон при общей внутренней поверхности, в слое которой отсутствуют армирующие волокна.1. The method of connecting two reinforced thermoplastic pipes with a seam obtained by flash welding, each pipe having an inner and outer surface, and the pipe wall extends from the inner surface of the inner pipe to the outer surface of the outer layer in the presence of one or more layers of reinforcing fibers, located in the outer half of the thickness of the pipe; the end sections of the pipes are heated by pressing them against the heating plate placed between them, so that the thermoplastic melts at the ends, and after removing the heating plate, the end surfaces are pressed against each other, displacing the molten material of the ends and causing the thermoplastic to flow outside and inside with the formation of internal and external rollers , after which the pipes are allowed to cool, while not allowing displacement of the axially disengaging them; one or each reinforcing layer is completely or partially expelled together with the overflowing material during the aforementioned upset, so that a layer of thermoplastic is formed in the weld between the layer or layers of reinforcing fibers with a common inner surface in which there are no reinforcing fibers. 2. Способ по п. 1, отличающийся тем, что после получения шва способом стыковой сварки плавлением на шов устанавливают муфту соединения электроплавлением, подключая ее к электропитанию на период времени, достаточный для соединения муфты с двумя трубами электросварными соединениями. 2. The method according to p. 1, characterized in that after receiving the seam by the butt fusion welding method, an electrofusion coupling is installed on the seam, connecting it to the power supply for a period of time sufficient to connect the coupling to two pipes with electrically welded joints. 3. Способ по п. 2, отличающийся тем, что удаляют наружный валик шва перед установкой муфты на шов, полученный способом стыковой сварки плавлением. 3. The method according to p. 2, characterized in that they remove the outer bead of the seam before installing the coupling on the seam obtained by the method of butt fusion welding. 4. Способ по п. 2, отличающийся тем, что между муфтой и наружной поверхностью труб предусматривают зазор и наружный валик образуют достаточно малым для того, чтобы он мог поместиться в радиальном зазоре. 4. The method according to p. 2, characterized in that between the coupling and the outer surface of the pipes provide a gap and the outer roller is formed small enough so that it can fit in the radial gap. 5. Способ по пп.2 - 4, отличающийся тем, что муфта соединения электроплавлением является промежуточной среди трех подобных муфт, соединенных встык, причем наружные муфты соединяют соответственно электросварными соединениями с указанными трубами. 5. The method according to claims 2 to 4, characterized in that the electrofusion coupler is intermediate among three similar couplings connected end-to-end, with the outer couplings being connected respectively by electrically welded joints to said pipes. 6. Способ по п. 5, отличающийся тем, что муфты соединения электроплавлением соединяют между собой стыковыми сварными швами. 6. The method according to p. 5, characterized in that the electrofusion coupling couplings are interconnected by butt welds. 7. Способ по п. 5 или 6, отличающийся тем, что сначала с трубами электросварными швами соединяют промежуточную муфту, после чего с трубами электросварными швами соединяют внешние муфты. 7. The method according to p. 5 or 6, characterized in that first, an intermediate sleeve is connected to the pipes with electric welded seams, and then external couplings are connected to the pipes with electric welded seams. 8. Трубы, соединенные способом по любому из предыдущих пунктов. 8. Pipes connected by the method according to any one of the preceding paragraphs. 9. Способ по п. 1, по существу соответствующий описанному выше со ссылкой на фиг. 1-5 прилагаемых чертежей. 9. The method of claim 1, substantially corresponding to that described above with reference to FIG. 1-5 of the attached drawings. 10. Способ по п. 1, по существу соответствующий описанному выше со ссылкой на фиг. б прилагаемых чертежей. 10. The method of claim 1, substantially corresponding to that described above with reference to FIG. b of the attached drawings. 11. Трубы, соединенные способом по п. 9 или 10. 11. Pipes connected by the method of claim 9 or 10.
