APPLICATION OF PECK FOR THE PRODUCTION OF COMPONENTS WITH LOW GAS PERMEABILITY

摘要

The invention mainly concerns the use of PEKK in order to reduce the CO2 and H2S permeability of a part intended to come into contact with a petroleum effluent. It also concerns a pipe for transporting a petroleum effluent, comprising a layer intended to be in contact with the petroleum effluent, characterised in that said layer intended to be in contact with the petroleum effluent comprises PEKK and has CO2 permeability at 130°C of less than 10-8cm3, for a thickness of 1 cm and a surface area of 1 cm2 and per second and bar of pressure of CO2 and/or H2S permeability at 130°C of less than 10-8cm3 for a thickness of 1 cm and a surface area of 1 cm2 and per second and bar of pressure of H2S, the quantity of CO2 and H2S being measured by GC, respectively. Finally, the invention also relates to several methods for producing such a pipe.
