PVC Foam Core-Layer Expanded Pipe Production Line

Feature and Function:PVC three layer pipe is used for water drainage, the outside layer and inside layer is made of rigid PVC. And the middle layer is made of specia formulation, with lower density 0.7-0.9g-cm3.Features:1. Saving raw material (density: 0.9-2-1.2g/cm3), lower cost.2. Smooth inside wall, low friction.3. High inpact resistance, the ring stiffness is 2 times of normal rigid PVC.4. High noise insulation.5. Safely protected from fire.6 High corrosion resistance.7. Long service life.8. Low installation charge, good benefits.
