HDPE/PVC Double-wall corrugated pipe is one kind of outer annular corrugated, smooth wall structure of a new plastic pipe.Compared with metal, ceramic, concrete and other pipes, double-wall corrugated pipe has many advantage such as lower weight, lower cost, erosion resistance, smooth inside-wall, high intensity, abrasion resistance, easy connection and so on. Its weight was significantly lower than the flat-wall pipe or concrete pipe, and connection, construction convenient, the cost of a significant reduction in pipe and increase the market competitiveness of the pipe. So it is used widely for sewerage and drainage system(larger diameter), cable protection system(smaller diameter), etc.
Main parameter of HDPE/PVC double-wall corrugated pipe production line:
