High-Performance Double Wall Corrugated Pipe Extrusion Lines from China Suppliers | Reliable Factory Solutions for PE, PP & PVC
Machine Parameters
High-Speed Single-Screw Extrusion Line (For PE/PP Pipes)
- Optimized Cooling & Molding: A newly designed, closed molding machine with a special high-efficiency cooling system for forming aluminum modules dramatically improves cooling rates, shortening cycle times for higher throughput.
- Stable High-Output Extrusion: Paired with a professionally designed corrugated pipe die, it enables large-scale, stable extrusion for demanding continuous production.
- Durable & Customizable Modules: Forming modules are made from precision-cast LY12 high-grade aviation aluminum (copper content ≥5%), ensuring high density, no porosity, and resistance to long-term deformation. Modules offer excellent interchangeability and customizable waveform designs.
- Precision Cutting: Features an automatic DWC cutter with computer control for accurate cut length, stable operation, and easy use.
| Type | Pipe Diameter (mm) | HDPE Output (kg/h) | Max Speed (m/min) | Total Power (KW) |
|---|---|---|---|---|
| JWSBL-300 | 110–300 | 500 | 5 | 440 |
| JWSBL-600 | 200–600 | 800 | 5 | 500 |
| JWSBL-800 | 200–800 | 1000 | 3 | 680 |
| JWSBL-1000 | 200–1000 | 1200 | 2.5 | 710 |
| JWSBL-1200 | 800–1200 | 1400 | 1.5 | 800 |
Conical Twin-Screw Extrusion Line (For FRPP/PVC Pipes)
- Energy-Efficient Production: The line's overall energy consumption is low. The conical twin-screw extruder offers higher conveying efficiency than single-screw models with lower installed power, enabling truly economical operation.
- Direct Powder Processing & Cost Savings: Capable of processing powder formulas directly (e.g., raw material + calcium carbonate), eliminating the need for pelletizing to significantly reduce raw material costs while enhancing pipe ring stiffness.
- Superior Pipe Quality: Equipped with a vacuum venting device to effectively remove moisture and air, preventing bubbles in the pipe wall for a dense, smooth interior and exterior surface.
| Type | Pipe Diameter (mm) | PVC Output (kg/h) | FRPP Output (kg/h) | Max Speed (m/min) |
|---|---|---|---|---|
| JWSBL-300 | 110–300 | 450 | 400 | 4 |
| JWSBL-600 | 200–600 | 800 | 800 | 3 |
| JWSBL-800 | 200–800 | 1200 | 1000 | 3 |
| JWSBL-1000 | 200–1000 | 1300 | 1200 | 2.5 |
| JWSBL-1200 | 800–1200 | 1400 | 1400 | 1.5 |
Parallel Twin-Screw Extrusion Line (For HDPE/PP Pipes)
- Excellent Mixing & Raw Material Flexibility: Utilizes two parallel co-rotating twin-screw extruders for superior dispersion. Can process both powder and granular raw materials simultaneously without pre-compounding, offering maximum formula flexibility.
- Online Formula Adjustment: Includes a side-feeding system allowing for real-time online adjustment of filler ratios (e.g., calcium powder), facilitating quick and convenient formula changes.
- Modular & Easy Maintenance: The building-block style screw and barrel assembly simplifies maintenance and part replacement, minimizing downtime.
| Type | Pipe Diameter (mm) | HDPE Output (kg/h) | Max Speed (m/min) | Total Power (KW) |
|---|---|---|---|---|
| JWSBL-600 | 200–600 | 800 | 5 | 500 |
| JWSBL-1000 | 200–1000 | 1200 | 2.5 | 710 |
| JWSBL-1200 | 800–1200 | 1400 | 1.5 | 800 |
Horizontal DWC Pipe Line (For Small-Diameter Pipes)
- Compact Solution for Small Pipes: Specifically designed for producing small-diameter DWC pipes (Ø50–250mm), ideal for drainage, venting, and conduit applications.
- High Plasticization & Output: Incorporates a new high-efficiency single-screw extruder that delivers greatly enhanced plasticizing capacity and high output of flexible pipe products.
- User-Friendly Operation: The horizontal structure of the molding machine provides a compact footprint and facilitates easier operation and maintenance.
| Type | Extruder | Main Motor (kW) | Line Speed (m/min) |
|---|---|---|---|
| JWSBW-50-110 | 45/33+45/33 | 30+18.5 | 0.6–6 |
| JWSBW-50-160 | 65/33+65/33 | 45+30 | 0.5–5 |
| JWSBW-110-250 | 75/33+65/33 | 90+45 | 0.4–4 |
