Corrugated pipe and forming module thereof

The invention discloses a corrugated pipe and a forming module of the pipe. The corrugated pipe comprises a corrugated pipe main segment and a flaring segment connected with the main segment, the flaring segment comprises an embedded segment and a sleeved segment, the embedded segment is a corrugated pipe body with the outer diameter smaller than the outer diameter of the corrugated pipe main segment, the sleeved segment is a straight pipe with the inner diameter larger than the outer diameter of the embedded segment and smaller than the outer diameter of the corrugated pipe main segment, a warping edge with trumpet-shaped flaring is connected to the sleeved segment, a circumferential bead for enhancing the intensity of the warping edge is arranged on the warping edge, and the forming module for manufacturing the corrugated pipe is disclosed. The circumferential bead is arranged at the position, close to the cutting position, of the flaring segment of the corrugated pipe, the flaring cutting intensity in the cutting process can be ensured, the intensity of the flaring segment in a connecting and mounting process is ensured, phenomena of cracking and folding are avoided, phenomena of water leaking, gas leaking and the like can be avoided, and the service life is effectively prolonged.
