发明名称 Tubo corrugado
摘要 The invention relates to a corrugated pipe of thermoplastic polymer material for use as fluid line with at least one polymer layer, comprising closed geometric outer contours which are spaced at an interval from each other in the axial direction of the pipe and which define a corrugation on the pipe jacket in at least one radial angular sector in axial, longitudinal direction one behind the other. The closed geometric outer contours are designed in such a manner that two jacket lines of the pipe jacket surface, which lines are approximately opposite one another, are free of corrugations and that these jacket lines extend in the longitudinal direction of the pipe (FIGS. 1b-1d).
