摘要：The invention relates to a flexible pipe having a multi-layered structure comprising unbonded layers, comprising an inner lining containing the following layers: a) at least one layer, the material of which is selected from the group consisting of polyolefin molding compound, polyamide molding compound and polyvinylidene fluoride molding compound and b) at least one layer, the material of which consists of a molding compound that is based on a polymer and selected from the group consisting of polyarylene ether ketone/polyphenylene sulfide blend, polyphenylsulfone and polyalkylene naphthalate, wherein the outer reinforcement is particularly efficiently protected against corrosion by corrosive components of the delivered medium that diffuse to the outside. The pipe is thus in particular suited for offshore applications in oil or gas production.
