Claims (13)

1. Способ изготовления двухосно ориентированной трубы из термопластичного материала, включающий насаживание трубы на оправку при температуре ориентации пластического материала, при этом оправка содержит расширенную часть, которая образует расширение в направлении окружности трубы, и приложение осевого тягового усилия к трубе после оправки, в ходе которого труба встречает сопротивление, которое противодействует движению трубы по оправке, отличающийся тем, что способ также включает оказание регулируемого воздействия по секторам в направлении окружности трубы на сопротивление, которое противодействует движению трубы по оправке.1. A method of manufacturing a biaxially oriented pipe from a thermoplastic material, comprising mounting the pipe on a mandrel at an orientation temperature of the plastic material, the mandrel comprising an expanded part that forms an expansion in the circumferential direction of the pipe, and applying axial traction to the pipe after the mandrel, during which the pipe encounters a resistance that counteracts the movement of the pipe along the mandrel, characterized in that the method also includes providing a controlled impact across sectors in ION circumference of the tube on the resistance which counteracts the movement of the tube over the mandrel. 2. Способ по п.1, в котором воздействие является, по меньшей мере, эффективным, когда трубу подвергают расширению в направлении окружности при пропускании ее по расширенной части оправки. 2. The method according to claim 1, in which the effect is at least effective when the pipe is expanded in the direction of the circle while passing it along the expanded part of the mandrel. 3. Способ по пп.1 или 2, в котором оказание регулируемого воздействия по секторам в направлении окружности трубы на сопротивление, которое противодействует движению трубы по оправке, включает воздействие на температуру пластического материала трубы. 3. The method according to claims 1 or 2, in which the provision of a controlled action across sectors in the direction of the circumference of the pipe on the resistance, which counteracts the movement of the pipe along the mandrel, includes the impact on the temperature of the plastic material of the pipe. 4. Способ по любому из предшествующих пунктов, в котором оказание регулируемого воздействия по секторам в направлении окружности трубы на сопротивление, которое противодействует движению трубы по оправке, включает воздействие на форму оправки. 4. The method according to any one of the preceding paragraphs, in which the provision of a controlled action across sectors in the direction of the circumference of the pipe on the resistance, which counteracts the movement of the pipe along the mandrel, includes impact on the shape of the mandrel. 5. Способ по любому из предшествующих пунктов, в котором оказание регулируемого воздействия по секторам в направлении окружности трубы на сопротивление, которое противодействует движению трубы по оправке, включает воздействие на трение между трубой и оправкой. 5. The method according to any one of the preceding paragraphs, in which the provision of a controlled action by sectors in the direction of the circumference of the pipe on the resistance, which counteracts the movement of the pipe along the mandrel, includes the impact on friction between the pipe and the mandrel. 6. Способ по любому из предшествующих пунктов, в котором оказание воздействия на сопротивление, которое противодействует движению трубы по оправке, регулируют в зависимости от характеристик трубы за оправкой. 6. The method according to any one of the preceding paragraphs, in which the impact on the resistance, which counteracts the movement of the pipe along the mandrel, is regulated depending on the characteristics of the pipe behind the mandrel. 7. Способ по п.6, в котором оказание воздействия на сопротивление, которое противодействует движению трубы по оправке, регулируют в зависимости от профиля поперечного сечения трубы, измеренного за оправкой. 7. The method according to claim 6, in which the impact on the resistance, which counteracts the movement of the pipe along the mandrel, is regulated depending on the cross-sectional profile of the pipe measured behind the mandrel. 8. Способ по одному или более предшествующих пунктов, в котором способ также включает регулирование осевого тягового усилия, оказываемого на трубу, в зависимости от профиля поперечного сечения трубы, измеренного за оправкой. 8. The method according to one or more of the preceding paragraphs, in which the method also includes adjusting the axial traction exerted on the pipe, depending on the cross-sectional profile of the pipe, measured behind the mandrel. 9. Способ по одному или более предшествующих пунктов, в котором, на некотором расстоянии после оправки, трубу протягивают через калибровочное отверстие, ограниченное калибровочным средством, при этом калибровочное отверстие таково, что оно производит уменьшение наружных размеров трубы. 9. The method according to one or more of the preceding paragraphs, in which, at a certain distance after the mandrel, the pipe is pulled through a calibration hole bounded by calibration means, wherein the calibration hole is such that it reduces the outer dimensions of the pipe. 10. Способ по п.9, в котором расстояние между оправкой и калибровочным отверстием регулируют. 10. The method according to claim 9, in which the distance between the mandrel and the calibration hole is adjusted. 11. Способ по п.10, в котором расстояние между оправкой и калибровочным отверстием регулируют в зависимости от наружных размеров трубы, измеренных за калибровочным отверстием. 11. The method according to claim 10, in which the distance between the mandrel and the calibration hole is adjusted depending on the external dimensions of the pipe, measured behind the calibration hole. 12. Способ по п.11, в котором расстояние между оправкой и калибровочным отверстием увеличивают, если измеренные наружные размеры трубы меньше, чем заданные наружные размеры, и в котором расстояние между оправкой и калибровочным отверстием уменьшают, если измеренные наружные размеры трубы больше, чем заданные наружные размеры трубы. 12. The method according to claim 11, in which the distance between the mandrel and the calibration hole is increased if the measured external dimensions of the pipe are smaller than the specified external dimensions, and in which the distance between the mandrel and the calibration hole is reduced if the measured external dimensions of the pipe is larger than the specified outer pipe dimensions. 13. Устройство для осуществления способа, согласно одному или более предшествующих пунктов. 13. A device for implementing the method according to one or more of the preceding paragraphs.
