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 armo ur layers. With the object of ensuring a low transport of heat through the walls of the pipe, one or more thermally-insulating laye rs (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.
