| description | The invention belongs to the technical field of PE pipeline manufacturing, and particularly relates to a manufacturing method of a PE pipeline. The manufacturing method comprises the following steps that molds which are correspondingly provided with a semi-cylindrical inner wall and a semi-cylindrical outer wall are connected together so as to be combined into a cylindrical through hole allowing the PE pipeline to pass therethrough; a plurality of forming grooves and flow guide grooves are formed in the circumferential direction of the inner wall, and at least one reinforcing rib forming groove is formed in the radial direction of the inner wall; and a PE material is poured and pass through the through hole so as to form the PE pipeline, and the two ends of the pipeline are outwards provided with flanging structures which are integrally formed. According to the manufacturing method of the PE pipeline, the reinforcing rib forming grooves are formed in the PE pipeline, so that in the manufacturing process, the |
