Method for making corrugated pipe

图片
In the pipe extrusion industry, there are basically two types of machines; the ones used in the production of PVC pipes with a relatively smooth exterior surface; and on the other hand, we have the ones used in the production of the PVC pipes with corrugated or wave surfaces. Now, the later can be either the single wall or the  double-wall corrugated pipe extrusion line . In this article, our focus would be on the  corrugated pipe extrusion machine  and their various applications. Let’s get started. Method for making corrugated pipe The corrugated tube refers to a tubular elastic sensor element connected by a foldable wrinkle sheet in a folding and stretching direction. For domestically produced corrugated pipes, the main forming methods include hydraulic forming, mechanical bulging and roll forming. Hydroforming and roll forming are more traditional bellows forming methods. Most of the small diameter corrugated tubes are formed by hydroforming. For large...
