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: A thermally insulated conduit pipe (22) is produced in that an inner pipe (2), onto which an outer pipe (13) has been extruded and which is enclosed by foam, is worked downstream of the extruder (12) with molding tools (16-21) in order to achieve deep undulation. This results in a conduit pipe having a small bending radius.

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.

摘要: A double-wall pipe includes a media-conveying inner tube, and a multilayer plastics outer tube with a gas permeation barrier layer. The plastics outer tube includes a significant proportion of polyethylene (PE). The gas permeation barrier layer consists of a compact extruded polyethylene terephthalate (PET) layer having a material thickness of from 0.8 mm to 2 mm or comprises a closed-cell foam made from PET having a material thickness of between 10 mm and 100 mm. A heat insulating layer is arranged in an annular gap between the inner tube and the plastics outer tube.

摘要: During the manufacturing of heat-insulated pipes (1) with an inner duct (3) and an outer duct (2) and a foamed insulation (14) arranged in between, the inner duct is placed on a tension member (10). The latter is tensioned between tensioning means by means of a tensile force, such that it runs straight and that the inner duct is held straight. The latter is held on centering elements (16, 17) which are spaced from one another in a defined way by means of spacers (18). In this straight position the inner duct may be surrounded with foam inside of the outer duct, without needing spacers between the ducts.

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.
