METHOD AND DEVICE FOR MANUFACTURING INSULATED TUBE
摘要
Method for manufacturing an assembly of a heat-insulation tube and at least a pipe (6) accommodated therein for transport of fluid, in which in a continuous consecutive series of process steps the pipe (6) is supplied, which pipe (6) may for instance be made of synthetic material or metal, a casing (7) of synthetic insulation material is extruded and arranged around the pipe (6), and in which by means of co-extrusion a sealing outer layer (18) is arranged around the casing.
