Patent ID: 10122158

Abstract:
The invention relates to a corrugated tube made of flexible plastic for encasing wires, having circumferential, successively alternating corrugation crests and corrugation troughs distributed over the axial length thereof, wherein the corrugation crests, seen in cross-section, perpendicular to the longitudinal axis of the corrugated tube, each have a corrugation along the outside circumference thereof which forms alternating radially protruding regions and radially inward-offset regions in the circumferential direction of each corrugation crest. The corrugated tube has wall sections, which extend axially over the length thereof and lie adjacent to each other in the circumferential direction, of which wall sections one forms the radially protruding regions in the corrugation and the other forms the radially inward-offset regions. Said wall sections consist of materials of varying hardness in circumferential alternation.
