    This plastic tube (1) has two expansions (2, 3) in the form of steps. A third expansion (5) is formed via an oblique wall part (4). The end region (6) is bent inwards, with the insertion of a head part (9) of a sealing device which consists of a head part (9) and of a sealing sleeve (10), in such a manner that the free end (7) ends close to the transition (8) from the oblique wall part (4) to the third expansion, and forms a retaining ring having a J-shaped cross-section. In consequence, the collar can be formed with a seal using extruded plastic tubes which can be produced economically. <IMAGE>

    one
    The invention relates to the field of mechanical engineering, namely, plastic pipes with a socket.
    Ants plastic pipe with a bell, in the internal cavity
    which is installed seal element C.
    A plastic pipe with a bell is also known, having two expanding sections, one of which is supported by the sealing element 12.
    However, well-known pipes do not provide reliable fastening of the sealing element.
    The purpose of the invention is to increase the reliability of pipe s on Il6.
    It is achieved by the fact that on the pipe there is a third extending section with an end edge bent in the direction of the second expansion section and forming an annular groove in which the sealing element is installed.
    FIG. I presents the described pipe with a bell, the end of which 25
    not yet bent in FIG. 2 is a diagram of the formation of an annular groove in a plastic pipe with a socket, the first stage; on fig.Z - the same, vtoro di a .30

    The plastic pipe 1 is bent by extrusion from a thermoplastic material, such as polyvinyl chloride, and has three expanding sections 2-4: the first section 2, the inner diameter of which is larger than the pipe diameter: the second section 3, the inclined transition wall 5 of which passes into section 4. The upper The end 6 of the plastic pipe 1 is bent so that it is again positioned along the axis of the pipe. The free end 7 of the upper end of the third portion 4 is located opposite the transition portion 8 between the third expanding portion and the inclined wall of the second expanding portion. In the space formed by the third section 4 and its curved free end, is located, the upper part 9 of the sealing element 10.
    The distance between the free end of the third section and the opposite section 11 of the socket is selected so that the upper part of the element 10 is securely clamped in the groove.
    Make a plastic tube with a bell as follows.
    The plastic pipe 1 is put on a mandrel having a first portion 12, passing into a second portion, the diameter of which is larger than the diameter of the first portion, and a third portion of the mandrel, into which the second portion passes.
    So form the first 2 and second 3 expanding sections of plastic pipe. The end, wider part of the mandrel forms the third expanding section 4 of the pipe.
    The upper end 6 of the plastic pipe is heated to the temperature at which the plastic deforms (for example, to a temperature of 140 ° C for polyvinyl chloride) and the outer surface of the pipe 1 by the first 2 and second 3 sections is rolled by the outer forming lining 13, which is supported by the wall 14 and fixed by the forming lining 15.
    With the help of a second lining 15 containing a wadding 16, the upper end 6 is bent in the radial direction after the upper part 9 of the sealing element, which is connected to the sealing lip, is installed in its place.
    With the help of the third outer forming lining 17, which is also provided with a recess 18, the upper end 6 is deformed so that its end is directed along the axis of the pipe 1.
    The inner diameter of the pipe at the point where the upper part 6 of the pipe is located and the inner diameter of the second expansion are filled with the same.
