Beschreibung
Zusammenfassung:	A pipe, which comprises the following layers: I. an exterior layer composed of a moulding composition which comprises at least 40% by weight of a polyamide whose monomer units contain, on average, at least 8 carbon atoms, III. an intermediate layer composed of a moulding composition which comprises the following components: a) from 70 to 99% by weight of polyamide, selected from PA6, PA66, PA6/66 and mixtures thereof and b) from 1 to 30% by weight of plasticizer, where the moulding composition comprises no impact modifier, and V. an interior layer composed of a moulding composition which comprises at least 40% by weight of a polyamide whose monomer units contain, on average, at least 8 carbon atoms, where a) the exterior diameter of the pipe is in the range from 6 to 20 mm, b) the wall thickness is in the range from 1.0 to 2.0 mm and c) the thickness of the polypropylene layer is from 25 to 75% of the wall thickness, is used as air-brake line which can be produced at low cost and which has high bursting strength and good low-temperature impact resistance.
