Beschreibung
Zusammenfassung:	The present invention relates to a metal corrugated pipe having a flare joint part, and a processing apparatus and a production method therefor, wherein the metal corrugated pipe having a flare joint part can significantly improve a function of preventing separation of a joint member and a sealing function due to expansion of an area contacting the joint member since the flare joint part for connecting the metal corrugated pipe is formed by directly processing the metal corrugated pipe and at the same time, an angle at which the flare joint part flares out with respect to the metal corrugated pipe is relatively large. The metal corrugated pipe having a flare joint part according to the present invention comprises: a corrugated pipe main body in which ridges and grooves are repeated along the longitudinal direction; and the flare joint part is formed on at least one side of both sides of the corrugated pipe main body with respect to the longitudinal direction, wherein the flare joint part is formed in a manner in which an end of the corrugated pipe main body flares outward. When the direction from the corrugated pipe main body toward the flare joint part is defined as the front, the outer diameter of the front end of the flare joint part may be formed to be 5-25% larger than the outer diameter of the corrugated pipe main body. La présente invention concerne un tuyau ondulé métallique ayant une partie de joint évasée, et un appareil de traitement et son procédé de production, le tuyau ondulé métallique ayant une partie de joint évasée pouvant améliorer de manière significative une fonction de prévention de la séparation d'un élément de joint et une fonction d'étanchéité en raison de l'expansion d'une zone en contact avec l'élément de joint du fait que la partie de joint évasée destinée à relier le tuyau ondulé métallique est formée en traitant directement le tuyau ondulé métallique et dans le même temps, un angle selon lequel la partie de joint évasée s'évase vers l'extérieur par rapport au tuyau ondulé métallique est relativement grand. Le tuyau ondulé métallique ayant une partie de joint évasée selon la présente invention comprend : un corps principal de tuyau ondulé dans lequel des crêtes et des rainures sont répétées le long de la direction longitudinale ; et la partie de joint évasée est formée sur au moins un côté des deux côtés du corps principal de tuyau ondulé par rapport à la direction longitudinale, la partie de joint évasée étant formée de telle
