The plant (10) produces a composite pipe (12) with a plastic inner pipe (27), metal pipe (16) and plastic outer pipe (39). The metal pipe is produced in a pipe making machine (13) from a metal strip (14), welding the seam at the welding point (18). The inner pipe is then extruded into the metal pipe from an extrusion device. The combined pipe is cooled in a first cooler (30) before the outer pipe (36) is extruded onto it. |
