Beschreibung
Zusammenfassung:	A method for producing a flexible pipe for offshore transport of fluids such as oil and gas, the method includes: extruding the internal pressure sheath of polymer material; winding one or more armor layers around the extruded internal pressure sheath; extruding the outer sheath of polymer material; at least one of the extruded sheaths of polymer material is extruded continuously along the length of the pipe wherein at least one zone A and at least one zone B are extruded along the length of the pipe and zone A is extruded from a polymer including polypropylene, and the extruded sheath in zone A has an Youngs-modulus EA zone B is extruded from a thermoplastic vulcanizate polymer, and the extruded sheath in zone B has an Youngs-modulus EB, where EB
