    摘要： In the method for the continuous production of a heat-insulated, corrugated line pipe (1) with at least one inner pipe (2), a corrugated outer jacket of the line pipe is first produced by means of an extruder (27) and a corrugator (28) and the inner pipe arranged in a foil tube together with a foam-forming starting material is guided into the corrugator, in which the outer jacket of the line pipe which has been corrugated before is filled with the heat-insulating foam. The device (10) provided for carrying out the method has a protective pipe (26) by means of which the inner pipe surrounded by the foil tube can be guided separately from the extrusion and corrugation of the outer jacket into the corrugator.

    摘要： The invention relates to the use of special polymer layers as barriers, in particular as barrier layers in composite materials. Suitable polymers for the polymer layer are copolymers consisting of ethylene and vinyl alcohol or consisting of ethylene and carbon monoxide or consisting of ethylene and carbon monoxide and propylene. These barrier layers exhibit a selective barrier effect with respect to different gases, the barrier effect being especially effective with respect to HFOs. On account of these properties, such barrier layers can positively affect insulating properties, for example in thermally insulated pipes.

    摘要： A coupling connection for corrugated pipes includes a coupling element, a support ring which is attachable in a positive fit against an inner wall face of the corrugated pipe, a first annular element which is axially fixable on a circumferential face of the corrugated pipe, a portion of the corrugated pipe being enclosed between the support ring and the first annular element and being fixable axially immovably, and an annular sealing chamber, enclosed circumferentially in a transition region between the support ring and the corrugated pipe, receiving a sealing element, on which a deformation force acts in a functional position which is fixable using a fixing element, including a second annular element, which circumferentially encloses the coupling element and is circumferentially attachable and movable in translation with respect thereto, the first annular element and the second annular element being arranged mutually coaxially.

    摘要： Thermally insulated pipes including thermal insulation, outer jacket and medium pipes, wherein the thermal insulation includes a foam having a density of 30-80 kg/m3, the outer jacket includes a thermoplastic plastic (21) having a modulus of 300-1400 MPa and having a corrugated shape. The invention further relates to the use as well as the manufacture of such tubes. Furthermore, the invention relates to composite materials, their use for thermal insulation, as well as their manufacture.

    摘要： The invention relates to a corrugated, thermally insulated conduit for fluids, e.g. for district heating networks, wherein at least one medium pipe (2) made of plastic or metal is surrounded by a thermal insulation layer (14), consisting of a polyurethane foam for example. The corrugation (25, 26) of the outer jacket (15) made of plastic is formed such that both the corrugation valleys (25) and the corrugation peaks (26) are round, particularly circular. In addition, the corrugation is dimensioned such that the corrugation depth T lies in a range of 4.5 mm to 8 mm for a conduit outer diameter range of 63 mm to 202 mm. This shaping and dimensioning of the conduit results in very good flexibility and thus the ability to roll up the pipe for the transport thereof.
