MULTILAYER TUBE AND USE THEREOF FOR FLUID TRANSPORTATION AT MEDIUM PRESSURE

摘要

Multilayer tube for fluid transportation, comprising, from the interior to the exterior: an inner layer comprising at least one polyamide in admixture with at least one elastomer; a first adhesive layer; a first layer comprising at least one polyolefin. The multilayer tube preferably further comprises a second layer comprising at least one polyolefin placed internally with respect to the inner layer and bonded to the inner layer by a second adhesive layer. Said tube is provided with high mechanical performance, in particular high resistance to the internal pressure exerted by the transported fluid, whilst still ensuring a suitable amount of flexibility. It can be used in particular for transporting hydrocarbons within the extraction site and from the extraction site to the refinery (the so called "upstream" sector).
