Definitions

  • the invention relates to the production of an adaptor made of plastic.
  • Traditional thermoplastic adaptors are usually produced by means of injection moulding.
  • an adaptor that is used as a junction account is taken of the fact that the opening on to which the branched pipe section is connected constitutes a significant weakening of the wall of the continuous pipeline.
  • such a weakening can be compensated for by enlarging the rim of the hole as well as the wall thickness of the adaptor itself.
  • the problem arises that the injection moulding of adaptors is hardly any longer economically justifiable. In such cases the adaptor has to be made up of individual pieces.
  • the aim of the invention is, therefore, to provide a method with which these problems can be circumvented and a pipeline section having improved strength characteristics can be produced in an economical manner.
  • Said aim is achieved by means of a method for the production of a prestressed pipeline section made of plastic, comprising the following steps: the provision of a first plastic pipe section, the provision of a second plastic pipe section having an internal diameter that is smaller than the external diameter of the first pipe section, modifying the cross-sectional dimensions of at least one end of a first of the pipe sections such that the end of the second pipe section can be fitted over the end of the first pipe section, pushing the pipe sections onto one another in such a way that compressive stresses are generated in the first (inner) pipe section and tensile stresses are generated in the second (outer) pipe section.
  • the starting materials for the method according to the invention can be pipe sections of standard dimensions.
  • a pipe section is preferably chosen that is identical to the pipe sections that are used in the remainder of the pipeline, so that the desired abutment is ensured.
  • first and the second pipe section have identical cross-sectional dimensions.
  • one or both pipe sections can be constructed with a conical end face. By means of end faces formed in this way it is possible to widen the one pipe section and to compress the other to some extent, specifically to such a degree that they can then be pushed over one another.
  • the pipe sections can be produced from a wide variety of plastics, for example semi- crystalline plastics such as polyethylene or polypropylene.
  • Pushing onto one another can be further promoted by heating the surfaces to be pushed onto one another.
  • a temperature of up to 60 °C can be chosen for this purpose.
  • the cohesion of the polyethylene material, and thus the prestress in the pipeline section is maintained, whilst, on the other hand, a significant reduction in the coefficient of friction, and thus of the shearing forces, is obtained.
  • a fluid can also be introduced under pressure between the pipe sections in order to lower the shearing forces.
  • the pipeline sections can be used in various ways. First of all, such pipeline sections can be used to produce adaptors, for example T-shaped junctions or bends. Secondly such pipeline sections can be used as complete prestressed pipes.
  • the method according to the invention comprises the following steps: the provision of at least a first and a second reinforced pipeline section, as described above, producing an end face that is oriented obliquely with respect to its axis at at least one end of both pipeline sections, - heating said obliquely shortened end faces of both pipeline sections, and welding the two pipeline sections to one another by pushing the heated end faces thereof onto one another.
  • the invention further relates to a prestressed pipeline section produced in accordance with the method as described above, wherein both pipe sections have the same length and completely overlap one another.
  • each pipeline section having an end face oriented perpendicularly to the axis thereof comprises only one pipe section over the region adjacent to said end face, and the other pipe section terminates some distance away from said end face.
  • Fig. 1 shows a tubular piece of starting material for a prestressed pipeline section according to the invention
  • Fig. 2 shows a piece of starting material divided into two parts, just before these are pushed onto one another;
  • Fig. 3 shows a cross-section through the finished prestressed pipe section
  • Figs. 4 to 6 shows the steps for the production of a T-shaped adaptor
  • Fig. 7 shows the finished T-shaped adaptor
  • Fig. 8 shows a bend
  • Fig. 9 shows a variant.
  • the pipe 1 of circular cross-section shown in Fig. 1 is the starting material for the production of a prestressed pipeline section according to the invention.
  • This pipe 1 is divided by means of a cut 2 into two pipe sections 3, 4, which have to be pushed onto one another.
  • the one pipe section 3 is flared at its end 5.
  • the end 6 of the other pipe section that faces said flared end 5 can have the original dimensions.
  • these pipe sections 2, 3 are then moved towards one another, the end 6 of the pipe section 2 penetrating into the flared end 5 of the pipe section 3.
  • the pipe sections 2, 3 can thus be pushed completely over one another, after which a pipeline section 7 is obtained which has the cross-section shown in Fig. 3.
  • the pipeline section 7 according to the invention can be used for various applications. First of all such a pipeline section can be used as a complete prestressed pipe, in which case the pipe sections 2, 3 have the same length and are pushed completely over one another. Such pipeline sections can then be welded to one another at the end faces to produce the desired length. According to a second possibility an adaptor, for example the T-shaped adaptor 8 shown in Fig. 7, can be produced using such a pipeline section 7 according to the invention. Three pipeline sections 7 are needed for this T-shaped adaptor 8, which pipeline sections 7 are joined to one another by the weld seams 9, 10 (see Fig. 7).
  • a T-shaped adaptor of this type is produced according to the steps shown in Figs 4 to 6.
  • First of all three pipeline sections 7 are produced for this purpose.
  • the shaded portion 12, 13 is removed from these pipeline sections along cuts running at 45 °C with respect to their axis.
  • these pipeline sections 7 are then joined to one another by their end faces 14, 15 defined by said cuts, an L-shaped junction 11 being obtained by this means.
  • a T-shaped adaptor can be obtained by means of the third pipeline section 7, by removing the shaded portions 16, 17 from, respectively, the L-shaped junction and the third pipeline section 7.
  • the L-shaped junction 11 and the third pipeline section 7 are then joined to one another at their end faces 18, 19 running at 45° with respect to the relevant axes, the T-shaped adaptor according to Fig. 7 being obtained.
  • Fig. 8 relates to a bend that is made up of four pipeline sections 7 which have been welded to one another by means of end faces (21) having a suitably chosen angle with respect to the associated axes.
  • the outer pipe section 3 terminates some distance away from the end face 20.
  • the normal pipe can be welded to this end face 20.
  • the first (inner) pipe section 2 has a conical end face 22 oriented outwards and the second (outer) pipe section 3 has a conical end face 23 oriented inwards.
  • the second pipe section 3 is pushed over the first pipe section 2. In this case it is not necessary first to flare the second pipe section 3.
