PP Soundproof pipes are produced by two extruders or three extruders, with three layer co-extrusion technology. The pipes are three layer structures with a sound-absorbing layer in the middel.

The popular soundproof pipe diameter is from 50-200mm. The pipe is made by co-extrusion technology with at least two extruders. The inner and outer layer is a thin PP layer, and middle layer is a special modified sound absorbing material. The Pipe structure is 3 layer, with thickness ratio is 10%:80%:10%.

Technical Data of Pipe Production Line:

Pipe Size:

Super silent drainage products has advantages of light weight, non-toxic, flame retarcant, corrosion resistance, aging resistance and high resistance performance.
Excellent soundproof performance; by adding special soundproof material to absorb sound waves and prevent sound spread, noise reduction is much better than case iron & upvc drainage pipe.
Super anti-corrosion: inner tube can resist acid up PH2, resist alkali up to PH12.
High temperature resistance: can bare 95ºC hot water.

1.Extruders are specially designed according the raw material's properties. Inner and outer layer is PP-B raw material, Middle layer is special PP-sound proof raw material. Bimetallic screw is adopted for Middle layer extruder, extend the machine service life.

2. Die head&Moulds are specially designed based on a large researches of the PP-B and PP silent raw materials characteristics. and considering the different shinkage ratio.

3. Special designed cutting machine, to ensure smotth cutting surface and also pipe roundness. With online cutting and chamfering function, save labor working time. Tailored design control system which can achieve 2 different length's consecutive cuts.

4. PLC control system with sync control to ensure easy and reliable operation of the line; and remote control to help customer to diagnosis machine problem if any and solve it.
