PVC Axial Hollow Wall Drain Pipe Equipment

The foamed pipe production line adopts three-layer composite co-extrusion technology, advanced process formula, and is equipped with a co-extrusion head with a spiral groove and a mandrel that can rotate at a uniform speed to produce UPVC, UPVC pipe, core layer foam pipe, foam inner Spiral tube, hollow wall inner spiral tube. This kind of pipe has low density, good sound insulation effect, obvious diversion and noise reduction function, and improves the drainage and ventilation capacity. Compared with the core layer foaming, the PVC inner spiral foam pipe reduces the noise by 5-7 decibels, and the noise is reduced by 7-15 decibels than the solid wall PVC pipe. It is an alternative product to replace ordinary pipes for building drainage in the new century.

Features of PVC foam pipe production line:

1. The PVC foaming pipe production line adopts two sets (foaming tube, one solid wall tube) conical twin-screw extruders with different outward rotation.

2. The composite co-extrusion head has a high quality of pipe material, and can be equipped with a mandrel with a spiral groove and can rotate at a constant speed to produce inner spiral foam and hollow wall inner spiral tube.

3. Vacuum sizing, spray cooling, smooth surface of the pipe.

4. The PVC foam pipe production line adopts centralized control, which is easy to operate and has a high degree of automation.
