Beschreibung
Zusammenfassung:	A flexible conduit used for transportation of hydrocarbon fluids for off-shore and on-shore oil and gas applications includes an inner pressure sheath, at least one reinforcing layer at least partially disposed around the pressure sheath, an outer protective sheath at least partially disposed around the at least one reinforcing layer, and optionally a thermally insulating layer disposed between the at least one reinforcing layer and the outer protective sheath. At least one of the inner pressure sheath, outer protective sheath, and the thermally insulating layer is manufactured using a thermoplastic blend (TPB) composition. The TPB compositions disclosed herein are useful for the formation of at least one polymer layer of the thermoplastic umbilical hoses used for transportation of hydrocarbon fluids. L'invention concerne un conduit flexible utilisé pour le transport de fluides hydrocarbonés pour des applications pétrolières et gazières, en mer et sur terre, qui comprend une gaine de pression interne, au moins une couche de renfort disposée au moins en partie autour de la gaine de pression, une gaine de protection externe disposée au moins en partie autour de ladite couche de renfort, et éventuellement une couche d'isolation thermique disposée entre ladite couche de renfort et la gaine de protection externe. La gaine de pression interne, la gaine de protection externe et/ou la couche d'isolation thermique est/sont fabriquées en faisant appel à une composition de mélange thermoplastique (TPB). Les compositions de TPB décrits dans la description de l'invention sont utiles pour la formation d'au moins une couche polymère des tuyaux ombilicaux thermoplastiques utilisés pour le transport de fluides hydrocarbonés.
