Definitions
- the invention relates to a pipe section of a double-walled chimney pipe for chimney construction, with a cylindrical inner tube, the one has an enlarged end, with a cylindrical outer tube, which is an enlarged End, and with one between the inner tube and outer tube arranged insulation.
- the invention also relates to a method for Production of such a pipe section.
- the pipe sections When creating chimneys on the outside of a building successively placed pipe sections on top of each other, the pipe sections be inserted into one another and the plug connection with an outside around the Pipe sections laid clamping band or a clamp is secured.
- the enlarged ends of the cylindrical inner tube and the cylindrical Outer tube are sleeve-like and arranged so that in Area of each end face of the pipe section is an expanded end.
- the insulation extends in the axial direction from the end face the extended end of the outer tube to the area where the Inner tube merges into its enlarged end, so that a between the enlarged end of the inner tube and the cylindrical part of the outer tube formed annulus is free of insulation. That's why the Interlocking adjacent pipe sections the extended end of the Inner pipe into the insulation of the next pipe section.
- the object of the invention is to provide a pipe section from which have gas and condensate-tight chimney pipes created with simple installation.
- the pipe sections should be easy to manufacture.
- 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 Pipe section, wherein the inner tube with its tapered end in a base body is set, which is in the level of the transition area from Inner tube to its tapered end is a support surface for insulation has, then the insulation on the support surface and outside is placed against and held against the inner tube, and then the outer tube with its conically widened end on the free face of the inner tube and the insulation put on and over the inner tube and Insulation is pushed.
- the insulation is there not damaged because the flared end of the outer tube is like a Funnel acts by resiliently deforming the insulation, so that after the outer tube has been pushed all the way between Outer tube and inner tube formed fill again and a 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 thereto, and 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 widened compared to its cylinder part 5. flared end 6 and one opposite its cylinder part likewise widened, tapered end 7.
- the outer tube 3 has a widened compared to its cylinder part 8, flared end 9 and one opposite its cylinder part likewise widened, conically tapering end 10.
- the conical Ends 6, 7 and 9, 10 each have the same cone angle in the area between 0.5 ° and 2 °.
- the tapered ends 7, 10 have over their length has a diameter that is greater than the diameter of their associated one Cylinder parts 5 and 8. Because all ends 6, 7 and 8, 9 are the same Have cone angles and expanded compared to their cylinder parts 5 and 8 they can be made using the same tools and with great precision, in particular with identical cone angles.
- the procedure is such that the inner pipe 2 with its tapered end 7 placed in a base body e.g. an annular space 11 recognizable in the figure below the conically tapered end 7 of the inner tube 2 and the conically widened Fills end 9 of the outer tube 3 and a support surface for the insulation 4 owns.
- the Partial shells of insulation 4 not shown, are placed and held on.
- the outer tube 3 with its conically widened End 9 placed 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. there the insulation 4 is resiliently deformed at least in some areas. If the outer tube 3 is pushed completely over the inner tube 2, the insulation 4 adapts to the contours of the inner tube 2 and outer tube 3 and forms a sufficiently firm connection between the inner tube 2 and Outer tube 3, the annular space 11 remaining free of insulation.
- the pipe sections 1 are successively placed on top of each other, each with an annular body 12 in the Annulus 11 of the adjacent pipe section engages. Center it the pipe sections 1 against each other automatically and arise because of the small cone angle sufficient holding forces so that the connection between neighboring pipe sections 1 not by additional measures, e.g. Clamping straps or clamps that need to be secured.
- the flared end 6 of the inner tube 3 has a circumferential, after outside bead 13, which acts as a capillary barrier or moisture collector for condensates, which then do not penetrate to the insulation can.
