Abstract
An armoured flexible pipe consists of an inner liner (), which surrounds a carcass (). On the other side of the inner liner () there are two armour layers, where the innermost () is a pressure armour layer, while the outermost () is a tensile armour layer. An outer sheath () 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 () 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.
