Abstract

The use of PEKK for lowering the COand HS permeability of a part intended to enter into contact with a petroleum effluent. Also, a pipe for transporting a petroleum effluent, including a layer intended to be in contact with the petroleum effluent, wherein the layer intended to be in contact with the petroleum effluent comprises PEKK and has a COpermeability at 130° C. of less than 10cm, for a thickness of 1 cm and a surface area of 1 cmand per second and bar of COpressure and/or an HS permeability at 130° C. of less than 10cmfor a thickness of 1 cm and a surface area of 1 cmand per second and bar of HS pressure, the amount of COand HS being measured by GC, respectively. Lastly, a number of methods for manufacturing such a pipe.
