Multi-functional PVC Pipe Production Line

Product Description

Adopting *-layer composite co-extruding technology and advanced technics direction, this production line, equipped with spiral groove and co-extruding machine head which can rotate at uniform velocity, can manufacture PVC core foaming pipe, PVC inner screw core foaming pipe and hollow-wall inner screw silencing drainpipe. This kind of pipe is characterized by light specific gravity which is only 0.***1.0g/cm3 about (but the specific gravity of un-foamed foaming pipe and PVC pipe is 1.4g/cm3 ) and excellent sound insulation. So that, the water falls along the pipe wall spirally and the noise problem is solved radically. Appraised by experts that, PVC inner screw core foaming pipe reduce **7 db of noise more than core foaming pipe, ***5 db than solid-wall PVC hard pipe and hollow-wall inner screw silencing drainpipe reduces ***0db than experiment PVC pipe.
