High-Speed Corrugated Pipe Extrusion Line for Conduit

This extrusion line is engineered to produce corrugated conduit pipes made from polymer materials such as HDPE. It covers a complete production workflow, from raw material feeding, plasticization and extrusion, corrugation forming, cooling, haul-off, to final roll winding. The line is designed for continuous production of cable protection pipes used in construction and industrial wiring scenarios. The system operates with an integrated control framework that coordinates each production stage, allowing operators to adjust process parameters based on production requirements. It supports the manufacturing of corrugated pipes with consistent wall thickness and uniform corrugation shape, suitable for cable insertion and fitting assembly in various installation environments.

Core System Configuration of Corrugated Conduit Pipe Extrusion Line

Extrusion Unit

The extrusion unit is responsible for melting and homogenizing raw polymer materials. It delivers stable melt pressure and temperature to ensure consistent material plasticization during continuous production. The screw structure is designed for HDPE processing, supporting uniform material output to match the forming speed of subsequent stations.

Corrugation Forming System

The forming system adopts a mold-based forming structure to shape the molten material into a corrugated profile. The molds are designed with precise cavity dimensions to ensure the outer diameter, inner diameter and corrugation pitch of the finished pipe match the set specifications. The system supports stable operation at adjustable production speeds.

Cooling and Haul-off Unit

After forming, the pipe passes through a cooling section to solidify the material and maintain its structural shape. The haul-off unit works in sync with the extrusion and forming speed, delivering stable traction force to avoid pipe deformation or dimension deviation during the conveying process.

Winding Unit

The winding unit rolls the finished corrugated pipe into fixed-length rolls, with adjustable winding tension to adapt to different pipe specifications. It supports automatic length metering to ensure each roll meets the preset length requirement.

Central Control System

The control system integrates parameter setting, real-time status monitoring and fault alert functions. Operators can adjust extrusion temperature, production speed and other parameters through the control panel, with real-time data display to support production process management.

Performance Attributes of High-Speed Corrugated Pipe Production Line

The line supports adjustable production speed within a specified range, allowing manufacturers to balance output and product quality based on order requirements. The forming mold structure ensures consistent corrugation shape across long production runs, reducing the rate of dimension deviation. It is compatible with HDPE and other common polymer materials for conduit pipe production, supporting material replacement with corresponding parameter adjustments. The pipe produced has a smooth inner wall, which reduces resistance during cable insertion. The integrated control structure reduces the need for manual intervention between production stages.

Application Scenarios for Corrugated Conduit Pipe Extrusion Equipment

Building Electrical Wiring

Corrugated conduit pipes produced by this line are widely used in residential and commercial building construction, serving as protective sleeves for electrical wires and cables. The pipes can be bent to adapt to complex wiring paths, and their material properties support installation in indoor and semi-outdoor environments.

Municipal Communication Cable Protection

The line can produce pipes for municipal communication and optical cable protection projects. The corrosion resistance of HDPE material allows the pipes to be buried underground, protecting internal cables from soil moisture and external mechanical impact.

Industrial Equipment Internal Wiring

For manufacturing equipment, automation production lines and mechanical devices, the corrugated pipes provide physical protection for internal control cables and power lines. The bending performance of the pipes supports routing around moving parts and narrow installation spaces.
