Flexible pipe (fP) suitable for transporting hydrocarbons, said flexible pipe comprising at least one polymer layer (L) composed of a polymer composition (C) comprising at least one poly(aryl ether ketone) (P1), and at least one per(halo)fluoropolymer (P2). The poly(aryl ether ketone) (P1) and the per(halo)fluoropolymer (P2) are advantageously homogeneously distributed in the polymer composition (C). The polymer composition (C) is profitably prepared by a method comprising tumble blending the per(halo)fluoropolymer (P2) on one hand, and the poly(aryl ether ketone) (P1) or part of the poly(aryl ether ketone) (P1) on the other hand.
