Abstract
In a method of producing a composite pipe for the transport of liquid or gaseous media, particularly for use in floor heating systems, an inner pipe (1) is first extruded from a thermoplastic synthetic resin material, this pipe (1) is then surrounded by a longitudinally-fed metal foil (2) coated on both sides with an adhesive, e.g. a copolymer, the edges of the strip overlapping or being welded together, and finally an outer pipe (4) is extruded onto the metal foil (2), the metal foil (2) thus being caused to adhere both to the inner pipe (1) and to the outer pipe (4). <IMAGE>
