Claims (9)

1. Способ расширения трубы из пластикового материала, в котором перемещающаяся вдоль своей длины труба постепенно увеличивается в диаметре под действием внутреннего давления текучей среды в зоне расширения между входной заглушкой, плотно перекрывающей трубу там, где она еще не подвергалась существенному расширению, и выходной заглушкой, плотно перекрывающей трубу после участка расширения, отличающийся тем, что расширение трубы контролируют согласно одному или более параметрам, прямо или косвенно выражающим измерение разности скоростей, с которыми вещество подается в зону расширения и удаляется из нее.1. A method of expanding a pipe made of plastic material, in which the pipe moving along its length gradually increases in diameter under the influence of the internal pressure of the fluid in the expansion zone between the inlet plug tightly overlapping the pipe where it has not yet undergone significant expansion and the outlet plug tightly overlapping the pipe after the expansion section, characterized in that the expansion of the pipe is controlled according to one or more parameters, directly or indirectly expressing the measurement of the speed difference th with which the substance is fed into the expansion zone and is removed therefrom. 2. Способность по п.1, отличающаяся тем, что параметр представляет собой разность скоростей трубы на входе и выходе зоны расширения. 2. The ability according to claim 1, characterized in that the parameter is the velocity difference of the pipe at the inlet and outlet of the expansion zone. 3. Способ по п.1, отличающийся тем, что параметр представляет собой скорость нерасширенной трубы, входящей в зону расширения. 3. The method according to claim 1, characterized in that the parameter is the speed of the unexpanded pipe entering the expansion zone. 4. Способ по п.1, отличающийся тем, что параметр представляет собой диаметр частично расширенной трубы в том месте зоны расширения, которое отстоит от входной заглушки менее чем на три нерасширенных диаметра трубы в направлении движения трубы. 4. The method according to claim 1, characterized in that the parameter is the diameter of the partially expanded pipe in that place of the expansion zone, which is less than three unexpanded pipe diameters from the inlet plug in the direction of the pipe movement. 5. Способ по п.4, отличающийся тем, что указанное место отстоит от входной заглушки менее чем на один нерасширенный диаметр трубы в направлении движения трубы. 5. The method according to claim 4, characterized in that said place is less than one unexpanded diameter of the pipe in the direction of movement of the pipe from the inlet plug. 6. Способ по п. 1, отличающийся тем, что параметр является аксиальной силой, приложенной со стороны расширенной трубы к калибровочному устройству. 6. The method according to p. 1, characterized in that the parameter is an axial force applied from the expanded pipe to the calibration device. 7. Способ по п.1, отличающийся тем, что расширение контролируют посредством изменения внутреннего давления текучей среды, находящейся в зоне расширения. 7. The method according to claim 1, characterized in that the expansion is controlled by changing the internal pressure of the fluid located in the expansion zone. 8. Способ по п.7, отличающийся тем, что расширение контролируют посредством управления утечкой текучей среды из зоны расширения через выходную заглушку. 8. The method according to claim 7, characterized in that the expansion is controlled by controlling the leakage of fluid from the expansion zone through the outlet plug. 9. Способ по п. 8, отличающийся тем, что выходная заглушка надувается внутренним гидростатическим давлением надувающей текучей среды, находящейся внутри выходной заглушки, а утечка контролируется путем изменения давления надувающей текучей среды 10. 9. The method according to p. 8, characterized in that the outlet plug is inflated with the internal hydrostatic pressure of the inflation fluid located inside the outlet plug, and the leak is controlled by changing the pressure of the inflation fluid 10.
