摘要： The present invention pertains to a process for lining a metal pipeline, said process comprising the following steps: (i) processing a thermoplastic polymer composition thereby providing a pipe liner having an outer diameter greater than the inner diameter of said metal pipeline, said thermoplastic polymer composition comprising, preferably consisting of: - at least one poly(aryl ether ketone) polymer [(PAEK) polymer], - at least one poly(phenylene sulfone) polymer [(PPSU) polymer], - optionally, at least one poly(arylene sulfide) [(PAS) polymer], and - optionally, at least one plasticizer; (ii) deforming said pipe liner thereby providing a deformed pipe liner having an outer diameter smaller than the inner diameter of said metal pipeline; (iii) inserting the deformed pipe liner in said metal pipeline; and (iv) expanding the deformed pipe liner to fit with the inner diameter of said metal pipeline. The present invention also relates to a pipeline system comprising at least two coaxial pipes, an outer metal pipeline and inner pipe comprising at least one layer comprising, preferably made of, said thermoplastic polymer composition.

摘要： The present invention pertains to a pipe comprising at least one layer at least comprising, preferably consisting essentially of (or being made of), a tetrafluoroethylene (TFE) copolymer comprising from 0.8% to 2.5% by weight of recurring units derived from at least one perfluorinated alkyl vinyl ether having formula (I) here below:
CF 2 =CF-O-R f (I)
wherein R f is a linear or branched C 3 -C 5 perfluorinated alkyl group or a linear or branched C 3 -C 12 perfluorinated oxyalkyl group comprising one or more ether oxygen atoms,
said TFE copolymer having a melt flow index comprised between 0.5 and 6.0 g/10 min, as measured according to ASTM D1238 at 372°C under a load of 5 Kg [polymer (F)].
The invention also pertains to use of said pipe in heat exchangers and in downhole operations including drilling operations.摘要翻译： 本发明涉及包含至少一个层的管，所述层至少包含，优选基本上由（或由其制成）四氟乙烯（TFE）共聚物，所述共聚物包含0.8重量％至2.5重量％的衍生自至少一种 （I）的全氟化烷基乙烯基醚：其中R f为直链或支链C 3 -C 5全氟化烷基或直链或支化C 3 -C 12全氟化烷氧基，其包含一个或多个 醚氧原子，所述TFE共聚物具有根据ASTM D1238在372℃和5Kg [聚合物（F）]的负载下测量的0.5至6.0g / 10min的熔体流动指数。 本发明还涉及所述管在热交换器中和包括钻井作业的井下作业中的用途。
