An armoured flexible pipe consists of an inner liner ( 3 ), which surrounds a carcass ( 1, 2 ). On the other side of the inner liner ( 3 ) there are two armour layers, where the innermost ( 5, 6 ) is a pressure armour layer, while the outermost ( 7, 8 ) is a tensile armour layer. An outer sheath ( 9 ) is finally applied around the armour layers. With the object of ensuring a low transport of heat through the walls of the pipe, one or more thermally-insulating layers ( 10 ) are extruded on the outside of the inner liner, where, depending on the use of the pipe, the layers can consist, for example, of a polymer or polymeric mixture, polyolefin, such as a polypropylene, or a polyketon. The flexible pipe according to the invention is especially applicable for use in the extraction, transport or refining of mineral oil or related fluids.
