A process for forming a steel wire reinforced composite pipe according to claim 3, wherein: v_{Around 0}-V_{Winding 1}＝V_{Winding 2}-V_{Around 0}And the winding speed of the forward steel wire and the reverse steel wire is V_{Winding 1}Is lifted to V_{Around 0}From V_{Around 0}Is lifted to V_{Winding 2}Making uniform acceleration motion with equal acceleration; the winding speed of the forward steel wire and the reverse steel wire is V_{Around 0}Down to V_{Winding 1}、V_{Winding 2}Down to V_{Around 0}The uniform deceleration motion is carried out and the speed is equal.

5. The process of claim 4, wherein the steel wire reinforced composite pipe comprises: and (3) cooling the first cooling box in the step S2 and the second cooling box in the step S7 in a vacuum spray cooling mode, and vacuumizing the interiors of the first cooling box and the second cooling box simultaneously by spraying the surfaces of the pipes with spray water.
