<p>An armoured flexible pipe consists of an inner liner (3), on the inside of which a carcass (1) is provided, while the outer side of the inner liner is surrounded by a layer of pressure armour and a layer of tensile armour, which in turn are surrounded by one or more layers of thermally insulating bands which are shielded from the surroundings by an outer sheath. With the object of ensuring a sufficiently low transport of heat through the walls of the pipe, on the outside of the pressure and tensile armour layers (5, 6, 7, 8) thermally insulating bands are provided, which bands are made of a polymer or a polymeric composition, such as a polymer containing at least 50 % polypropylene. The armoured flexible pipe according to the invention is especially advantageous for use in the extraction, transport or refining of mineral oil or related fluids.</p> |
