Patent ID: 8006722

Claim:
A pipeline for conducting air, in particular in a temperature range between −55° C. and +85° C. and at a differential pressure load of at most ±500 hPa relative to cabin pressure, for air conditioning in aircrafts, the pipeline comprising: a body portion formed with foamed plastics material and/or with a dense plastics material, the body portion extending along a pipeline longitudinal axis and including an outer face and an inner face defining a closed cross-sectional geometry; and a wrapping positioned on the outer face and/or the inner face, the wrapping including at least one linear reinforcing element, the wrapping including a plurality of layers located one above the other in contacting relationship, each layer including a plurality of windings wound in the same direction, wherein the windings of adjacent layers are wound in opposite directions to form a net-like structure of the wrapping, at least one of a spacing between the windings along the pipeline longitudinal axis and an angle of slope between the windings and the pipeline longitudinal axis varies in certain sections to change the winding density as a function of local mechanical load requirements of the pipeline, and the linear reinforcing elements for forming the windings are formed with at least one continuous fiber which is enclosed by a matrix formed from at least one of a thermosetting plastics material and a thermoplastic polymer.
