Definitions

  • the invention relates to a pipe section of a double-walled chimney pipe for chimney construction, with a cylindrical inner pipe which has an enlarged end, with a cylindrical outer pipe which has an enlarged end, and with an insulation arranged between the inner pipe and the outer pipe.
  • the invention also relates to a method for producing such a pipe section.
  • pipe sections When creating chimneys on the outside of a building, pipe sections are placed one after the other, the pipe sections being plugged into one another and the plug connection being secured with a clamping band or a clamp clamped around the outside of the pipe sections.
  • the widened ends of the cylindrical inner tube and the cylindrical outer tube are designed like sleeves and are arranged in such a way that an enlarged end is located in the region of each end face of the tube section.
  • the insulation extends in the axial direction from the end face with the widened end of the outer tube to the region in which the inner tube merges into its widened end, so that an annular space formed between the widened end of the inner tube and the cylindrical part of the outer tube is free of Insulation is.
  • the object of the invention is to provide a pipe section from which gas and condensate-tight chimney pipes can be produced with simple assembly.
  • the pipe sections should be easy to manufacture.
  • both the inner tube and the outer tube have a widened, conically widening end and a widened, conically tapering end, that the conical ends have the same cone angle and the conically tapered ends have their long larger diameters than the cylinder parts of the inner tube or outer tube, that a conically tapered end and a flared end are arranged in the region of each end face of the tube section, and that between the tapered end of the inner tube and the flared end of the outer tube formed annular space is free of insulation.
  • all the conical ends have the same cone angle, which can preferably be between 0.5 ° and 2 °, and because an annular space free of insulation is formed in the region of an end face of the pipe section, successive pipe sections can be plugged onto one another without problems, as it were from center yourself. With small cone angles there are also sufficiently large holding forces between adjacent pipe sections and the desired gas and condensate tightness is guaranteed.
  • the length of the conical ends and thus their degree of coverage should be at least 60 mm for pipe diameters of up to 1,000 mm.
  • the insulation extends from the end face of the tube section with a conically tapered outer tube and a flared inner tube to the transition region between the inner tube and its tapered end or the outer tube and its flared end.
  • the insulation can consist of prefabricated mineral partial shells with a density of approx. 120 kg / m 3 and a compressive strength of approx. 10 kN / m 2 .
  • the partial shells are sawn or milled from a prefabricated body, so that the inner diameter of the partial shells corresponds to the outer diameter of the inner tube and the outer diameter of the partial shells corresponds to the inner diameter of the outer tube.
  • the invention also relates to a method for producing such a tube section, the inner tube with its conically tapered end being placed in a base body which has a support surface for the insulation at the level of the transition region from the inner tube to its conically tapered end has, then the insulation is placed on the supporting surface and on the outside against the inner tube and held thereon, and then the outer tube with its conically widened end is placed on the free end face of the inner tube and the insulation and is pushed over the inner tube and the insulation.
  • the insulation is not damaged because the conically widened end of the outer tube acts like a funnel in which the insulation is resiliently deformed, so that after the outer tube has been completely pushed on, it fills the annular space formed between the outer tube and the inner tube and is sufficient forms a firm connection between the outer tube and inner tube.
  • the double-walled chimney pipe shown is intended for chimney construction. It consists of several pipe sections 1 arranged one behind the other, of which only two pipe sections are shown. Each pipe section 1 has an inner pipe 2 and an outer pipe 3 arranged concentrically therewith as well as an insulation 4 arranged between inner pipe 2 and outer pipe 3.
  • the tubes are made of stainless steel.
  • the insulation consists of prefabricated mineral partial shells, not shown in detail, with a density of approx. 120 kg / m 3 and a compressive strength of approx. 10 kN / m 2 .
  • the inner tube 2 has a conically widening end 6 widened with respect to its cylinder part 5 and a conically tapering end 7 also widened with respect to its cylinder part.
  • the outer tube 3 has a conically widening end 9 which is widened in relation to its cylinder part 8 and an end 10 which is also widened and conically tapered in relation to its cylinder part.
  • the conical ends 6, 7 and 9, 10 each have the same cone angle in the range between 0.5 ° and 2 °.
  • the tapered ends 7, 10 have over their length has a diameter that is larger than the diameter of their associated cylinder parts 5 and 8. Because all ends 6, 7 and 8, 9 have the same cone angle and are expanded compared to their cylinder parts 5 and 8, they can be used with the same tools and great precision, especially with identical cone angles.
  • the procedure is such that the inner pipe 2 with its conically tapered end 7 is placed in a base body which, for fills an annular space 11 recognizable in the figure below between the conically tapered end 7 of the inner tube 2 and the conically widened end 9 of the outer tube 3 and which has a support surface for the insulation 4.
  • the partial shells of the insulation 4 (not shown) are placed on this support surface and against the inner tube 2 and held there.
  • the outer tube 3 is then placed with its flared end 9 on the free end face of the inner tube 2 and the insulation 4 and pushed over the inner tube 2 and the insulation 4.
  • the insulation 4 is resiliently deformed, at least in some areas.
  • the pipe sections 1 are placed one on top of the other, an annular body 12 engaging in the annular space 11 of the adjacent pipe section.
  • the pipe sections 1 center against each other automatically and arise because of the small cone angle sufficient holding forces so that the connection between adjacent pipe sections 1 does not need to be secured by additional measures, for example clamping bands or clamps.
  • the conically widened end 6 of the inner tube 3 has a circumferential, outwardly directed bead 13 which serves as a capillary barrier or moisture collector for condensates which cannot then penetrate to the insulation.
