HDPE/PP/PH-H Doube structural hollowness wall spiral winding pipe extrusion production line

1. HDPE Large diameter spiral pipe (diameter from 200mm-4000mm) has high ring stiffness and high brunt intensity with "H" structure. It can be used for approximate 50 years and has many advantages such as low cost assembly and easy operation, with standing pressure, corrosion resistant such as acid, alkali and salt etc. It is becoming as a replacement of cement pipe and cast iron pipe nowadays. It is being widely used as sewage and drainage pipe.

2. HDPE large diameter hollow wall winding pipe machine .
**The HDPE large diameter hollow wall winding pipe extrusion line is designed with advantaged technology and improved based on long time practice experience. Diameter range can be 200-3000mm.
**Our machine is featured with comfortable operation and high performance/price ratio.
**Due to our special design, it is very convenient in transportation and installment.
**We also developed energy saving method to save energy consumption in large diameter hollow wall winding pipe extrusion.
**By adopting two sets of high efficient extruders, the output capacity is big. Our winding pipe extrusion line can make pipe with ring stiffness 4, 8, 12KN/m2. All parts precisely designed and manufactured so the whole extrusion line works stably and reliably.
**Special design for easy maintenance.
**The HDPE large diameter hollow wall winding pipe extrusion line is mainly used for producing large diameter hollow wall winding pipe.
