Abstract
The invention relates to a coaxial pipe with a defined separation between the outer circumference of the inner pipe and the inner circumference of the outer pipe. This defined separation is produced by means of spacing arranged in the unobstructed space between the inner pipe and the outer pipe. Strips (1) of polymer material are used as the means of spacing. Knob-like projections (11, 12, 13) are fitted on one side in these strips (1), offset in sections with respect to one another. These knob-like projections (11, 12, 13) are arranged at least in two rows, offset with respect to one another, on the surface of the strip (1). <IMAGE>
