Definitions
- the invention relates to a fluid-carrying and in particular water-carrying pipe with thermal insulation, which can be used in particular in the heating and / or sanitary sector.
- Heating pipes require a diffusion barrier so that no oxygen can get through the wall of the pipe from the outside.
- the fluid-carrying pipe is made of plastic, it is provided with a diffusion barrier layer made of, for example, EVOH.
- a diffusion barrier layer made of, for example, EVOH.
- Such a pipe is used for insulation purposes of thermal insulation material, e.g. Surrounded by PE or PUR foam, whereby this insulation layer is surrounded by a plastic outer jacket, which is usually designed as a corrugated pipe.
- thermal insulation material e.g. Surrounded by PE or PUR foam
- the invention is based on the object of creating an insulated heating and / or sanitary pipe with an inner pipe structure, for the production of which standard pipe components can be used.
- an insulated heating and / or sanitary pipe which is provided with an inner pipe made of a plastic material, a corrugated pipe made of metal surrounding the inner pipe at a radial distance, a compressible and / or expanded material between the inner tube and the corrugated tube for fixing the inner tube within the corrugated tube, the compressible and / or expanded material for exposing a connection end of the inner tube being detachable therefrom, an insulation layer surrounding the metal corrugated tube and an outer jacket around the insulation layer.
- the heating and / or sanitary pipe has an inner pipe made of plastic, which e.g. Oxygen or, generally speaking, gas permeable, but need not be.
- an inner pipe made of plastic, which e.g. Oxygen or, generally speaking, gas permeable, but need not be.
- this is surrounded by a corrugated metal tube.
- the space between the two is filled with a compressible and / or expanded material.
- This material can be detached from the plastic material of the same for exposing a connection end of the inner tube, in a simple manner and in particular manually, so that the compressible and / or expanded material at the connection end of the inner tube can be removed by, for example, introducing a radial circumferential incision. So now you can get to the exposed
- connection end of the inner tube Connect a commercially available fitting, for example a press fitting, to the connection end of the inner tube.
- thermo insulation material PE or PUR foam
- an outer jacket in the form of e.g. a plastic corrugated tube is surrounded.
- the advantage of the invention is to be seen in the fact that the inner tube structure is oxygen and water vapor tight due to the metal corrugated tube, so that no moisture can get into the insulation layer. Due to the flexibility of the Entire pipe due to the metal corrugated pipe, the pipe can be easily installed as well as wound up and unwound.
- a lengthening of the inner tube is counteracted by the tube structure according to the invention, since this is held by the inner tube and the outer tube via the material.
- the linear expansion of the entire pipe is thus determined by the linear expansion of the metal outer pipe.
- the installation of the pipe according to the invention can be simplified since the overall pipe can be plastically deformed due to the metallic outer (corrugated) pipe.
- the compressible and / or expanded elastic, flexible material is in particular a foam material.
- the permeability tightness in the heating and / or sanitary pipe according to the invention is achieved by the corrugated metal pipe, for which it does not matter whether the plastic inner pipe is already gas-impermeable.
- the production of corrugated metal is a common and common process.
- the metal corrugated pipe can be welded in the form of a longitudinal seam or spiral, or the corrugated pipe structure is realized by shaping a (smooth) metal pipe with subsequent deformation to form the corrugated pipe.
- a pipe made of plastic material that is customary for pipe use, for example PP or PE can be used as the actual media-carrying inner pipe.
- the invention is explained in more detail below with reference to the drawing, which shows a section through a heating and / or sanitary pipe according to the invention, shown in perspective.
- the heating and / or sanitary pipe 10 has an inner pipe 12 made of plastic, in particular cross-linked plastic, which is surrounded at a radial distance r by a corrugated pipe 14 made of metal, in particular aluminum.
- a compressible and / or expanded foam material 16 is used to fix the inner tube 12 within the corrugated tube 14 and fills the space formed by the radial distance r.
- the foam material 16 can be easily detached from the inner pipe 12 to expose a connection end of the inner pipe 12 to be connected, for example, to a fitting, in particular detachable without residue.
- the inner tube 12 is fixed within the corrugated tube 14 by the foam material 16.
- the corrugated tube 14 serves as a water vapor and / or oxygen barrier (the latter in particular when the plastic inner tube 12 does not have an oxygen diffusion barrier layer, for example made of EVOH) and gives the entire tube 10 the necessary permeation tightness.
- the inner tube structure described above is surrounded by a heat insulation layer 18, around which an outer jacket 20 made of plastic and designed as a corrugated tube is arranged. Due to the vapor barrier as a result of the metallic material of the corrugated tube 14, no moisture reaches the heat insulation layer 18 from the inner tube 12, as a result of which the tube 10 maintains its insulation properties over its service life.
