The invention discloses a production line of a steel wire reinforced composite pipe. According to the production process of the composite pipe, the production line sequentially comprises a core pipe extruder, a first cooling box, a first traction machine, a steel wire winding machine, a glue layer extruder, a gluing mold, a first cold air ring, a coating mold, an outer layer extruder, a second cold air ring, a second cooling box, a second traction machine and a cutting machine, wherein the steel wire winding machine is driven by a longitudinal driving device to longitudinally slide. By means of the production line, the steel wire winding machine can longitudinally move in the running direction of the pipe in the production process of the composite pipe, so that even if the traction speed of a core pipe is increased, the relative speed between first and second pay-off assemblies and the core pipe is reduced, and enough reel changing time is ensured.
