Abstract: A method for producing an insulated pipe in corrugated casing (100) comprising the steps of: covering an inner pipe assembly (105) comprising at least one inner pipe (101) with a film (106); dispensing an expandable insulation material (102) in a liquid state between the inner pipe assembly (105) and the film (106) thereby preparing an initial pipe assembly (107) comprising a layer of expanding insulation material (102a) positioned between the film (106) and the inner pipe assembly (105); extruding a layer of outer casing (104) onto the initial pipe assembly (105) before the insulation material has expanded completely, thereby creating a still expanding insulated pipe assembly (118); and leading the still expanding insulated pipe assembly (118) through a corrugator (205) having an inner corrugated surface giving the casing (104) a corrugated shape as the at least one layer of expanding insulation material (118) continues to expand.
