Zusammenfassung: | The invention belongs to the technical field of oil exploitation and well repair, and particularly relates to a flexible composite pipe for oil gathering and transportation and composite pipe manufacturing equipment and method. The flexible composite pipe for oil gathering and transportation is of a multi-layer structure and comprises an inner pipe, an anti-wax deposition layer is arranged on the inner wall of the inner pipe, a reinforcing layer wraps the outer wall of the inner pipe, and an outer pipe is arranged on the outer side of the reinforcing layer. The intelligent manufacturing method solves the problems that when an existing flexible composite pipe is used in the field of oil gathering and transportation, oil-resistant swelling occurs, and a pipeline is subjected to wax precipitation and blockage after a pipe body runs for a long time, the intelligent manufacturing method is adopted, and the problems that in the trial-manufacturing process of the flexible composite pipe, manual winding and traction |
