Use of tubing as temperature control tubing in motor vehicles, wherein a temperature control medium is passed through the tubing. The tubing has the following layer structure from the outside inward: an exterior layer of at least one polyolefin, a first adhesive barrier, a barrier layer of at least one polyamide, a second adhesive barrier and an interior layer of at least one polyolefin.

The entire wall thickness of the tubing is 0.5 to 3.5 mm.

Multilayer motor vehicle temperature control tube for fluid temperature control media, with the tube having at least three layers. Going from the outside to the inside, the layer structure comprises an outer layer of polyethylene or of a thermoplastic vulcanizate (TPV), an intermediate layer of polypropylene (PP) and an inner layer of polyethylene or of a thermoplastic vulcanizate (TPV). The total layer thickness of the tube is 0.7 to 2.5 mm.

A plastic tubing having at least two layers for a fluid cooling system includes a first layer being formed from an ethylene tetrafluoroethylene or a fluorinated ethylene propylene based plastic material and configured as an internal lining formed of a fluorocarbon plastic material. Further, a second layer is configured as a sheathing to the first layer and formed from polyamide material. An adhesive layer may be disposed between the first and second layer and at least one other layer may be configured as an external sheathing of the plastic tubing formed from an elastomer based material.

A multi-layered pipe comprising a wall having a polyolefin inner layer and a barrier layer being an outer layer relative to the polyolefin inner layer, the barrier layer being formed of a non-metallic barrier material, which barrier material has relative to polyolefin an enhanced resistance to permeation therethrough of hydrocarbon molecules, the pipe further comprising a protective layer being an outer layer relative to the barrier layer, the pipe further comprising a peelable layer between the polyolefin inner layer and the barrier layer, the peelable layer being formable around the polyolefin inner layer by means of extrusion. The protective layer and the barrier layer may together be incorporated in a single layer.

A device for transporting a medium includes at least one channel which extends in an axial direction and through which the medium is guided. The channel is enclosed by an electrically conductive inner envelope that is connected to a first potential equalization conductor. An electrically conductive outer envelope is provided between the channel and an electrically conductive outer casing and is connected to an electrically conductive second potential equalization conductor. Arranged between the channel and the outer envelope is an electrically insulating intermediate layer which is produced from heat-insulating material.

A multilayer motor vehicle pipeline, wherein at least one barrier layer comprised of at least one material from the group butene diol-vinyl alcohol copolymer (BVOH), polyvinyl alcohol (PVOH), polymer blend with BVOH, polymer blend with PVOH is provided. At least one outer layer made of plastic is arranged on the exterior side of the barrier layer.

The invention provides a cross-linked fluororesin having excellent abrasion resistance against metal. The cross-linked fluororesin is obtainable by cross-linking a fluororesin. The fluororesin contains a tetrafluoroethylene unit and a vinylidene fluoride unit, and the tetrafluoroethylene unit represents 50.0 mol % or more of all the monomer units constituting the fluororesin.

A piping includes: a hose made of an elastic material; a pipe made of metal, the pipe having an insertion part inserted inside of the hose; and a sleeve arranged on an outer side of the insertion part and the hose in a radial direction. The insertion part has an uneven surface around an outer circumference side of the insertion part, and the uneven surface has an annular groove and an annular projection. The groove has a groove slope that narrows the pipe toward a tip end of the insertion part, and a groove bottom that extends from an insertion-tip-side end of the groove slope to the projection with a constant outer diameter. The sleeve has a small diameter part located on an outer side of the uneven surface in the radial direction to press the hose against the uneven surface.

A plastic tubing having at least two layers for a fluid cooling system includes a first layer being formed from an ethylene tetrafluoroethylene or a fluorinated ethylene propylene based plastic material and configured as an internal lining formed of a fluorocarbon plastic material. Further, a second layer is configured as a sheathing to the first layer and formed from polyamide material. An adhesive layer may be disposed between the first and second layer and at least one other layer may be configured as an external sheathing of the plastic tubing formed from an elastomer based material.

A high-pressure hose relating to the present disclosure has, within a hose main body, four or more reinforcing layers at which linear reinforcing materials extend in spiral shapes, wherein, at two reinforcing layers that are adjacent in a hose radial direction, a pitch length of the reinforcing material at the reinforcing layer that is disposed at an outer side is shorter than a pitch length of the reinforcing material at the reinforcing layer that is disposed at an inner side.
