It is convenient to construct and check circuity. Because the silicon core pipe has the lowest friction coefficient,it is very to draw the cable inside. t is new cable hose following PVC, double-wall corrugated pipe and multi-pipe. t resent, t is widely used for communication project, highway and railway project.
There are different models to meet your need. The HDPE Silicon Core Pipe extrusion Line is good telecom pipe plastic machinery.
