The PP super silent drainage pipe line adopts special designed high efficient extruder for viscoelastic sound-absorbing PP material, to ensure the extrusion efficiently and improve the service life of the extruder.

Co-Extrusion Die Head 
Special designed adjustable co-extrusion die head of this PP mute pipe line is our unique patented products. 
Layers Distribution-10:80:10, and each layer's thickness can be adjusted easily;
Specialized Three layers spiral pressure storage composite die head, for stable and compact extrusion;

Vacuum Calibration  Tank 
Casing material is SS304 Stainless Steel, with special surface painting treatment for this PP drain pipe production line ;
Installed Inner Pipe tray (stand) adjusted device for convenient operation. 
Water temperature was automatically controlled by Siemens PLC Control System

PLC Control System
The PP soundproof drainpipe making line adopts new generation Siemens PLC programmable computer control system, which could ensure the whole line high-speed synchronous control and its stable & reliable running.

Manufactured Pipe 
The noise reduction of this pipe is better than cast-iron pipe, even the current market dominated UPVC drainage pipe. Indoor water dropping noise is less than 45dB. 
It also has following advantages, such as, high resistance to bending fatigue strength, high temperature deformation resistance, aging resistance and other unique performance, 
Being widely used at office buildings, schools, hotels, high-rise residential buildings, hospitals,nursing homes, the drainage of high temperature waste water of spa and bathplaces etc.
