Abstract: An insulated conductor including: at least one electrical conductor; and, an insulating coating covering said electrical conductor, having n layer(s), “n” being an integer greater than or equal to 1, the nth layer being the outermost layer having a pseudo-amorphous composition Cn including at least 50% by weight of a polyaryletherketone. A process for manufacturing the insulated conductor, a heat-welding process using two sections of insulated conductor, and a coil capable of being obtained by heat-welding a winding of the insulated conductor.

Abstract: A process including: the provision of a semicrystalline or crystallizable composition, having a glass transition temperature Tg, including at least one polyaryletherketone; the provision of a compression forming means including: a mold, the mold having at least one cavity; the preparation of the composition in the molten state in said at least one cavity, the mold having a temperature T0 at the end of the preparation stage; the compression and the cooling of the composition in the molten state, the mold being cooled from the temperature T0 down to a final temperature Tfof less than or equal to (Tg+30)° C., to form a compression-formed article; and the removal of the compression-formed article from the mold; in which the composition has a melting point strictly of less than 340° C.

Abstract: The use of PEKK for lowering the CO2 and H2S 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 CO2 permeability at 130° C. of less than 10−8 cm3, for a thickness of 1 cm and a surface area of 1 cm2 and per second and bar of CO2 pressure and/or an H2S permeability at 130° C. of less than 10−8 cm3 for a thickness of 1 cm and a surface area of 1 cm2 and per second and bar of H2S pressure, the amount of CO2 and H2S being measured by GC, respectively. Lastly, a number of methods for manufacturing such a pipe.
