To provide a method for molding a polyethylene pipe to the inner surface of pipeline which contrives durability of pipeline and facilitation of the molding of the polyethylene pipe to the inner surface of the pipe line.
This method for molding the polyethylene pipe 7 to the inner surface of the pipeline 1 comprises a process of lining the inner surface of the pipeline 1 with a liquid resin 21 and forming an adhesive layer 2 on the inner surface of the pipeline 1, a process of attaching powdery polyethylene resin 3 to the surface of the adhesive layer 2 with an air stream and a process of bonding the powdery polyethylene resin 3 which is attached to the surface of the adhesive layer 2 by using heated pressurizing liquid 6. Therein, the powdery polyethylene resin 3 is bonded by melting to the surface of the adhesive layer 2 consisting of the liquid resin 21 and the polyethylene pipe 7 is molded on the inner surface of the pipeline 1.
