DUCT WITH SHEATH HAVING REDUCED PERVIOUSNESS TO ACID COMPOUNDS

The pipe is intended for carrying a petroleum effluent comprising at least one of the acid compounds CO2 and H2S. The pipe comprises at least one metal element (3, 5) and a tubular sheath made of a polymer material (2, 4), the metal element being provided outside the sheath. The sheath consists of a...

More Information
Summary:The pipe is intended for carrying a petroleum effluent comprising at least one of the acid compounds CO2 and H2S. The pipe comprises at least one metal element (3, 5) and a tubular sheath made of a polymer material (2, 4), the metal element being provided outside the sheath. The sheath consists of a mixture of a polymer material with a predetermined amount of products chemically active with said acid compounds so as to irreversibly neutralize the corrosive effects of said compounds and to limit the corrosive effects on said metal elements. The pipe is characterized in that the chemically active products are incorporated into the sheath in form of particles of specific surface area above 5 m2/g.
