The Corrugated Pipe
- May 14, 2018 -


The corrugated pipe is formed by the corrugated plate, and corrugated plate is generally made of sheet roll forming, roll forming, continuous forming system and special pass system. At present, the most widely used production corrugated plate is continuous forming system, namely, first, bending center wave, then bending adjacent wave, and finally bending wave. The advantage of this system is the lowest roll consumption, its disadvantages are the workpiece is easy to come out, now transverse bending and distortion. The special hole system is mainly used for the production of corrugated plate. In the beginning stage, the curved wave is prebent, and then the locking pressure is formed. The method ensures that the metal is thinned at the corners. Its disadvantage is high roll consumption, high requirement for forming equipment and materials.
