Part 1: Plastic Double Wall Corrugated Pipe Making Machine

1. HDPE double-walled corrugated pipe application: 
 HDPE / PP double wall corrugated pipe is widely used as drain pipe. The company absorbs foreign advanced technology, independent research and development of the HDPE double wall corrugated pipe production line, with a number of patented technologies. Our new high-speed PE | PP double-wall corrugated pipe production line, the use of new high-performance single-screw extruder, forming machine using horizontal structure, shuttle drive, sealed water-cooled, online flaring, high degree of automation, stable operation, large output.
 
2. PE / PP double wall corrugated pipe production line, can be used to produce ID90-ID1200 specifications of the single-walled, double-wall corrugated pipe (with Pipe Belling), three-wall corrugated pipe, different shapes and special requirements of special-shaped bellows.

3. Main technical parameters:
Single screw extruders with big  LD, 36:1, and Long die-head

Part 2. HDPE large diameter hollow wall winding pipe 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.

Feeder ,Drying hopper and  Extruder
High production capacity of extrusion on the high quality basis. Lower temperature plasticizing design, ensure high quality extrusion. 

Pipe Extusion Die head

Die head is a tool used to form goods, which mainly realizes the processing of the shape of the goods through the change of the physical state of the formed material.

Vacuum calibration water tank and Water cooling tank

It is stainless steel materials.
It could be water leaching cooling way or water spray cooling way according pipe diameters and extrusion speed.

Haul-off machine

The main function of the tractor is to clamp the pipe after cooling and forming, and transport the pipe forward smoothly and evenly by providing a certain traction speed and traction force.

Glue welding extruder

It has the function of easy operation and maintenance

5. What can the machine produce?
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.
