High Speed HDPE Double Wall Corrugated Pipe Production Line
Product Description
Double Wall Corrugated Pipe Production Line is a new type of high-speed water-cooled corrugated pipe production line independently developed and designed by our company on the basis of advanced foreign technologies.It mainly adopts polypropylene (PP) or high-density polyethylene (HDPE) as raw materials to produce single-wall and double-wall corrugated pipes.
Application:
It is widely used in urban water supply and drainage, underground infiltration, construction water supply and drainage, wire and cable laying, bridge steel cable sheathing, agricultural irrigation and other fields. It will gradually replace the plastic pipe, cement pipe, cast iron pipe due to low assembly cost, easy operation, convenient connection and economical construction. It enjoys broad application prospects and great market potential.
Features and Advantages
Advantages of the New High-Speed PE/PP Double Wall Corrugated Pipe Production Line:
→Higher production speed: mold adopts continuous circumferential pressure water cooling along the entire running track, delivering superior cooling effect. The output can be up to 3 times higher than models with air cooling or conventional water cooling
→Lower power consumption: the extruder is equipped with a buffered forced feeding zone, which greatly reduces power consumption of the main drive motor (by 30%)The screw features a large L/D ratio of 36:1, offering strong material adaptability and excellent plasticization effect.
→Mold Interchangeability: Molds for large and small production lines are fully interchangeable, facilitating production organization, reducing inventory, and shortening delivery time.
→Easier operation: No vertical adjustment of the forming machine platform is required, and module replacement is quick and convenient
→More stable and durable: The movement tracks of modules and water circuits are smoother. Cooling water lines adopt fixed connections, eliminating water seepage and equipment wear caused by frequent pipe plugging/unplugging, thus extending service life,Shorter flow channel in the die head results in lower pressure, reducing wear and prolonging the service life of the screw and die head

| Drive Method |
- Bilaterally distributed gears. This multi-point servo drive mode ensures stable operation with low resistance and high precision
|
- Vertically distributed gears, main drive at the lower part, lead to uneven stress on the module and high operating resistance
|
| Forming Machine Structure |
- Shuttle-type transmission, freely opening /closing left/right frames;
- forming area can be automatically opened, no cumbersome adjustments required for mold change/maintenance
|
- Traditional horizontal design with fixed frames;
- forming area is mostly closed/semi-closed, overall disassembly/assembly required for mold change, low efficiency
|
| Module Design |
- Precision cast aluminum alloy;
- independent cooling/vacuum channels; high strength, long service life, strong heat dissipation
|
- Ordinary steel/simple aluminum molds;
- shared cooling and vacuum channels, easy deformation,poor heat dissipation
|
| Platform Adjustment |
- No vertical adjustment needed
|
- Vertical adjustment is required;
|
| Cooling System |
- Circumferential continuous sealed pressure water cooling with high cooling efficiency;
|
- Open back spray cooling + return section air cooling with low cooling efficiency and high energy consumption
|
| Extrusion System |
- Adopts a buffered forced feeding section
- High-speed and high-efficiency single screw with grooved barrel design; dual-machine co-extrusion with independent feeding for inner and outer layers, compatible with different raw materials.
- Dual-flow channel, 45° angle extrusion die head with short flow channel, low melt pressure/temperature, and uniform pipe wall thickness.
|
- Traditional feeding section, resulting in high power consumption and large power of the main drive motor.
- Conventional single screw / twin screw with average plasticization efficiency; long flow channel in the die head, easily leading to high melt pressure, high melt temperature and high energy consumption.
|
| Power Consumption |
- Low power consumption; The extruder systerm design reducing main drive motor power consumption by 30%
|
- High power consumption;
- The extruder design resulting in high power consumption of the main drive motor.
