pvc core-layer expanded pipe production line

is used for water drainage.,the outside layer and inside layer is made of rigid PVC,and the middle layer is made of special formulation,with lower density 0.7-0.9g/cm3.

Features:

1.Saving raw material(density:0.9-1.2g/m3),lower cost.

2.Smooth inside wall,low friction.

3.High impact resistance,the ring stiffness is 2 times of normal rigid PVC.

4.Stable,applicable for temperature range:-30-70.

5.High noise insulation.

6.Safely protected from fire.

7.High corrosion resistance.

8.Long service life.

9.Low installation charge,good benefits.
