Double Layer Corrugated Pipe Machine In West Bengal

Understanding the Dual-Layer Corrugated Pipe Production Process. Double-layer corrugated pipe manufacturing involves the simultaneous extrusion of two material layers into a shared die head. The merged molten stream is directed into a mold-based corrugator where it is vacuum-formed or pressure-shaped into a ribbed profile. The inner layer typically offers flexibility, while the outer layer delivers strength and environmental protection.

Core Assemblies That Drive the Machine Line

• Primary and Secondary Extruders – Individually heat and process polymers
• Dual-Layer Die Head – Precision tool that aligns, presses, and combines two flows.
• Corrugation Module with Closed-Chain Molds – Consistently shapes the pipe using interlocking mold blocks.
• High-Efficiency Cooling Section – Air or water-based cooling quickly stabilizes form.
• Servo-Controlled Puller & Flying Cutter – Ensures clean, accurate pipe lengths.
• Digital Display & PLC Interface – Allows custom setup, synchronized functions.
• Automatic Coil or Stack System – Collects final products based on the pipe

Why This Machine Is Essential in Industrial Pipe Fabrication

Reduced Material Waste: Uses recycled polymers for the inner layer without sacrificing quality.

Enhanced Wall Strength: The corrugated exterior shields against soil pressure and load.

Versatile Line Speeds: Speed is automatically adjusted to match extrusion volume and cooling rate.

Consistent Wall Thickness: Built-in sensors ensure uniformity across the production cycle.

Multi-Diameter Output: Switch between 40 mm to 200 mm sizes by modifying tooling in minutes.

System Integration with Digital and Auxiliary Equipment This machinery integrates seamlessly with feeding systems, gravimetric dosing units, and remote diagnostic controls. It also supports programmable batch output, allowing integration with ERP systems and IoT dashboards for smart manufacturing environments.

Where Double Wall Corrugated Pipes Are Commonly Used. These pipes are widely used in commercial and industrial applications, including:

1. Buried Drainage and Sewer Systems
2. Underground Electrical Conduits
3. Agricultural Water Flow Channels

Subsurface Ventilation Shafts. These products are used in diverse industrial applications that demand long-term durability with lightweight handling.

Adaptable Features for Material and Pipe Customization Operators can select from HDPE, LDPE, and PP for extrusion, and control wall ratio settings via HMI panels. The system allows manual or automatic mold replacement for various profiles—circular, elliptical, or even slot-perforated, depending on end-use needs.

Maintenance Strategy to Prolong Line Performance

Inspect Corrugator Tracks Weekly for mold wear and alignment.

Flush the Cooling System Monthly to remove scaling or blockages.

Replace Seals and Bearings Annually to avoid vacuum loss or drag.

Log Operating Hours to plan preventive service and limit production halts.
