Corrugated pipe manufacturing system and method

The invention provides a corrugated pipe manufacturing system and method, the corrugated pipe manufacturing system comprises a first device, a second device and a third device, the first device adopts an expansion forming technology to conduct primary shaping on the first position of a plate, and after primary shaping, the first position of the plate is subjected to secondary shaping; a first arc-shaped convex part which is convex towards a first surface far away from the plate is formed at a first position of the plate; the second equipment adopts the rolling forming technology to conduct secondary shaping on the first position of the plate, after secondary shaping, a first arc-shaped concave part protruding towards the second surface away from the plate and a second arc-shaped convex part protruding towards the first surface are formed in the first position of the plate, and the second arc-shaped convex part is further shaped for the first arc-shaped convex part; the second surface of the plate is opposite
