Abstract:
The present invention relates to a hybrid pipe (1) for stay cable, comprising a tubular shaped wall (15), the wall having an internal face (18) and an external face (19). The hybrid pipe (1) further comprises at least one reinforcing element (12, 22), the reinforcing element (12, 22) being provided at the wall (15) to form the hybrid pipe (1) such that the hybrid pipe (1) has a higher mechanical properties/resistance such as higher buckling resistance, higher tensile strength and/or a lower thermal dilatation than the wall (15) itself. The present invention also relates to a cable-stayed system comprising such a hybrid pipe (1) and a method of manufacturing such a hybrid pipe (1).
