Abstract (en)
[origin: WO2011103606A2] The invention relates to a method for producing a composite pipe (13) which comprises at least one inner pipe (2), an insulating material layer (8) and a jacket pipe (11), a foamable insulating material being introduced in an insulating material molding section (21) which extends around the inner pipe (2) in an insulating material introduction section by means of a blow gun, the insulating material being molded in an insulating layer molding section to give the insulating material layer (8) and the jacket pipe (11) being applied around the molded insulating layer (8), and the composite pipe being heated in the insulating layer molding section, the insulating material introduction section and the insulating layer molding section being heated or cooled to a defined temperature range.
