More Information
Summary:An underwater pipe, including a metal reinforcing layer around an inner polymeric sealing sheath capable of being in contact with hydrocarbons. The inner polymeric sealing sheath includes a homopolymeric polypropylene or a mixture of homopolymeric polypropylenes, wherein the homopolymeric polypropylene or the mixture has a density greater than 0.900 g/cm3, and a melt index measured at 230° C. under a mass of 2.16 kg of less than 10 g/10 minutes, its preparation method and its use for the transport of hydrocarbons. Such a sheath may be used in contact with hydrocarbons at high temperature.
