Definitions

  • the invention relates to methods for producing a high-pressure pipe connection.
  • the invention further relates to a high-pressure pipe connection produced by this method.
  • sleeves and / or clamps made of thermally weldable material provided with a heating device.
  • the known sleeves, or clamps consisting of two segments are placed on a pipeline to be processed and the two segments are connected to one another.
  • the heating device is then energized and heated via the heating conductor installed in it in such a way that sleeves or the two segments of the clamp form a cohesive weld connection with one another and with the pipeline.
  • these known types of connection cannot be used for high-pressure pipelines.
  • a combination of butt welding and heating coil welding is used for high pressure pipelines. Steel structures are used for line transitions to other networks.
  • the object of the invention is to create a method for producing a steel-free high-pressure pipe connection and pipe connection.
  • the solution to this problem is characterized by the process steps:
  • the method according to the invention is characterized in that the support structure which determines the statics of the pipe connection and which is also suitable for use on high-pressure pipelines is created by the formation of the insert consisting of a fiber-reinforced plastic material.
  • the use of glass-fiber-reinforced or carbon-fiber-reinforced polyamide is preferably proposed as the material for forming the fiber-reinforced insert.
  • the adhesive to be applied to the insert is preferably an adhesive copolymer.
  • Adhesion copolymers are characterized by the fact that, with the appropriate equipment, they combine very well with other plastics, in particular polyethylene, and that when a plastic is sprayed directly onto an adhesion copolymer, it partially melts and a fusion weld connection is formed between the two plastics. Since polyethylene is preferably used for the encapsulation of the insert and thus for the formation of the pipe connection, adhesive copolymers in particular are particularly well suited as adhesive agents.
  • the invention is characterized by a high-pressure pipe connection with an essentially sleeve-shaped heating device and an insert made of a fiber-reinforced plastic material and arranged coaxially and at a distance from the heating device, the insert and the heating device being integrally connected to one another via an injection-molded plastic material.
  • openings for the injection molded plastic material forming a base body are formed in the insert.
  • tubular sleeves and clamps consisting of two segments
  • a sleeve manufactured according to the invention in the connection of a fitting, for example in the pipe connection piece of a shut-off valve, or as an outlet clamp for drilling under gas pressure.
  • At least one pipe outlet is formed on the base body, a recess at least corresponding to the inside diameter of the pipe outlet being formed in the heating device and / or the insert.
  • Fig. 1 shows a schematic longitudinal section through a first embodiment of a high-pressure pipe connection according to the invention
  • Fig. 2 shows a schematic longitudinal section through a second embodiment of a high-pressure pipe connection according to the invention.
  • the high-pressure pipe connections shown in the figures in FIGS. 1 and 2 each consist essentially of a base body 1, an insert 2 embedded in the material of the base body 1 and an at least partially heating device 3 forming the inner surface of the sleeve.
  • the sleeve-shaped heating device 3 is arranged on a mandrel and then the sleeve-shaped insert 2, which is also coated with an adhesive and made of a fiber-reinforced plastic material, is arranged coaxially and at a distance from the heating device 3 on the outside of the heating device 3.
  • This preassembled arrangement is then inserted into an injection mold and molded around with a plastic material, preferably polyethylene, to form the socket base body 1.
  • a materially welded connection is formed between the material of the base body 1 and the materials of the insert 2 and the heating device 3.
  • the heating device essentially consists of a thermoplastic base body, on which at least one heating conductor is fixed at least on one side.
  • the heating conductor is preferably arranged helically in the sleeve-shaped heating device 3.
  • the insert 2 is coated with the adhesive, for example by means of a spraying or sintering process.
  • the insert 2 has openings 4 so that the material of the base body 1 can reach the heating device 3 radially and can additionally claw for the welding to the insert 2.
  • the sleeve has recesses 5 widening the inner diameter of the sleeve on both sides. These recesses 5 serve as stop surfaces for the pipelines to be inserted into the sleeve, the outer surface of which is partially peeled off. The part of the pipeline that has been peeled off and thus reduced in outside diameter is accommodated in the middle part of the sleeve, which has the smaller inside diameter. With the larger outside diameter, the pipe lines pushed into the socket on both sides run against the recesses 5, as a result of which the insertion depth of the pipe lines into the socket is limited and defined.
  • the pipeline is peeled down to the innermost layer, which usually consists of polyethylene.
  • the heating device 3 is energized via connections 6, as a result of which the heating conductors of the heating device 3 melt the plastic material of the base body on the one hand and, on the other hand, the jacket surfaces of the pipelines to such an extent that a materially welded connection is formed.
  • the second embodiment shown in FIG. 2 differs from the embodiment according to FIG. 1 in that a pipe outlet 7 is formed on the base body 1 in this second sleeve, wherein in the heating device 3 and / or the insert 2 there is at least an inside diameter d of Pipe outlet 7 corresponding recess is formed.
  • a high-pressure pipe connection designed in this way is distinguished by the fact that it guarantees a high-pressure-tight connection to the pipes with a simple construction.
