A corrugated tube extrusion process according to claim 8, wherein the step 3 comprises the following steps: Step 3.1: The raw material of the bellows enters the feeding zone, and the temperature of the feeding zone is controlled at 90~100℃; Step 3.2: The raw material of the bellows enters the melting zone, and the temperature of the melting zone is controlled at 260~280°C; Step 3.3: The raw material of the bellows enters the extrusion zone, the temperature of the extrusion zone is controlled at 260~270℃, and the pressure is controlled at 25~30MPa.
